Lara looked over her shoulder at me with a sinister half smile. My back was turned, but somehow I could feel her grin as her eyes bored into the back of my head. I looked over my own shoulder back towards her with an expression that showed some concern. Just as we locked eyes she returned her attentions to Derrick who was moaning so hard I could swear he was dying from pleasure. Charity wasn't much different. Each thrust seemed to elicit a gasp and moan to the point that she seemed to inhale and exhale simultaneously. I held her legs apart, her body contorting into something that resembled a Y yet folded in half. Holding up her ankles separate at double the width of my shoulders I was methodically maximizing penetration while she seemed to lay as still as possible.
"Damn, baby, I think I'm about to cum. Again!" I heard Derrick shout. Just then I felt Charity's pussy contract around me and her eyes opened just long enough for her irises to flash a flourescent pink. The image made me pause just as she convulsed into an orgasm simultaneous to Derrick's own. She arched her back as she seemed to convulse again and again, her ass leaving the cushions entirely. For a moment I thought she was seizing.
"Well, Derrick," Lara sighed, standing up on the coffee table, "That was fun but... I'll need my man back."
"Leaving so soon baby?" he whimpered, Lara licking her teeth in response. She turned around and grabbed me, pulling me away from Charity who looked at us with disappointment, her thick lower lip puckering in a pout that almost looked sexy.
"Mind if I borrow him?" Lara asked.
"But... I want more..." Charity whispered in reply, a hand moving unconsciously towards her neglected pussy.
"There's a man," Lara argued, nodding towards Derrick whose eyes were on us. "He happens to want more too. Keep each other busy," she grinned.
In that instant, Charity seemed to snap. Not even allowing Derrick to answer or get up she jumped on him, literally. I couldn't believe what I was seeing because as she leapt off the couch on onto him, his dick slid straight into her pussy. It was like she aimed, but I doubted anyone could pull off such a feat aside from Lara, perhaps. "Whoa, baby I thought we were broken up!"
"Oh, just shut up and let me fuck you!" Charity shouted. She began bouncing up and down vigorously as though his dick held a winning lottery ticket. Derrick blinked, seemingly just as shocked as I was about her sudden change in attitude. Was this the same girl? Then it dawned on me. The supernatural pink flare of her irises...
"Lara did you-" I was interrupted by a sudden passionate kiss that she planted on my lips. For a brief moment I thought of how those lips were wrapped around another man's... maleness, but the taste of fresh strawberries lulled those thoughts away. She was also hot, as in burning up. I wondered if she was alright but the way she nonchalantly guided my dick back into her warm, wet snatched convinced me she was healthy.
"Let's see if you have anymore in you," she whispered.
I looked over to see Charity on top of Derrick and going to town. She had stripped down fully in between mounting her man and now, taking the opportunity to massage and carress her perfectly shaped boobs that were capped with tiny pink nipples. "Baby, I'm about you cum," Derrick warned.
"That's okay, hun, cum inside me. I want it all," she shouted back. He gave out a grunt and then released. That's when I saw it. Right before my eyes the pair changed. Derrick seemed to shrink, his muscular frame seeming to soften just a little bit and his shoulders narrowing just so that it was barely noticeable, but it was there. By contrast, Charity seemed to grow. Her body became more defined, as hints of biceps, abs, and thighs seemed to come out of nowhere. She seemed to grow about an inch taller and her boobs inflated just a hint but I swear I could see it. "Oh, baby... that was... amazing..."
"R-really?" he asked, sounding surprised. She smiled and nodded, leaning down and squishing her breasts against him as she planted a kiss on his forehead and then dismounted him. This time he softened, the monstrous meat seemingly had enough, finally. As Charity stood, it confirmed my suspicions: Derrick had shrunk about an inch while Charity had grown in similar measure. Where there used to be a defined five inch gap, the difference could only have been three now. They both stared at us as Lara pushed me to another climax, her moaning and sighing really showing them up. After a few brief moments I came, hard.
"That's it baby," she whispered to me, stroking my cheek lovingly. "You really are the best."
"I wouldn't say the best, but he is pretty good," Charity contradicted. Lara rolled her eyes, obviously not believing a word that came out of the girl's mouth. With no response received, Charity began to dress herself, only turning to Derrick after she had once again donned the emerald panties that she had abandoned for me. "Listen, Derrick, maybe I was a bit to harsh when I said we were done. I still love you and... I see now that I haven't been a very good girlfriend."
"No shit?" the other asked in unadulterated shock.
"Of course not. You deserve sex whenever you want, and it's my responsibility to give it to you. So from now on, anytime you want laid," she paused, grabbing his collar and pully him down to her level for dramatic effect. "Tell me, and I'll fuck your brains out," she smiled, planting a deep kiss on him. "Come on, let's go get something to eat, then maybe we'll move on to round two," she giggled as the two gathered their belongings and left.
I sat there in silence for a bit, Lara next to me, caressing my flesh with her silky smooth finger. "What the fuck was that?" I finally asked.
"Your first foursome. But I doubt it'll be your last group activity." I blinked. I liked the sound of that but it really wasn't what I was referring to.
"No, I mean... did you do something to them?" I asked, already knowing the answer. I mean realistically in the span of 24 hours she's changed my whole family and gave Stacy a dick that Heather's probably still riding, so it seemed more likely that Lara did do something.
"Of course I did," she smiled.
"You gotta stop fucking with people like this, it's wrong," I growled.
"Really? And what, exactly have I done wrong? I made your family love you and each other better. I siphoned off your mother's grief, reignited your father's passion, and- oh yes, gave your sister her dream body. As for Stacy and Heather, well, you wanted me to get them together."
"You chose an odd way of doing that."
"I can't just make someone bisexual or lesbian. Attraction doesn't work that way and forced sex produces toxic energy. Stacy was a flaming lesbian who wouldn't want anything to do with anything remotely resembling a man and Heather's love of the dick was far to strong to simply dismiss. So I gave Stacy something she would never volunteer to have in exchange for attracting the one person she wanted in life. I can influence people's lust and even push them to engage in sex but even in the most orchestrated circumstances, they always say yes and it's always of their own free will."
"Okay," I relented, feeling embarrassed by my rushing to judgement, "So what did you do to them?"
"Oh... you'll probably find out in a few days. Just don't be surprised when she comes knocking on your door." I grimaced. There was fun and then there's was such a thing as too playful. Succubus or not she took way to much pleasure in these things. But, if I had to wait, I had to wait.

"Oh, oh, oh yeah baby come on, just a little bit more, just a little bit more baby." Charity moaned like a common slut as she rode Derrick's manhood to climax. Since their run-in with Lara and Jethro, Charity and Derrick's sex life had taken a drastic new turn. Charity wanted sex all. the. time... At first Derrick welcomed the desire, the lust, and the insistance. He had felt wanted like never before. In fact, he actually considered that he may not have to cheat ever again. After all, he had always blamed Charity for his sex drive. She was hot and lovely but her stand-offish attitude made those stary-eyed, come pre-lubricated freshman look so enticing. So he fucked them. Any girl he thought he could get away with was in his bed and out by morning. His only mistake was gaining that reputation; the reputation that literally any freshman with decent looks could crawl into his bed and sample his sausage. That's how Charity found out. The best way to get out of the situation was to simply blame his prude of a girlfriend, so that's what he did. It worked at first, but Charity didn't like sex all that much, so eventually she gave up trying to keep up with him. Now, ironically, he was desperately trying to keep up with her. He was buying condoms daily, and when he ran out, she took it raw, not even caring if he came inside her. She would just always get this weird glint in her eyes and rub her belly while licking her lips. Was she equating him filling her insides with eating him? He shuddered at the thought, but something weird was happening. He had been shrinking. He no longer stood as tall, felt as strong and his member... was no longer its usual nine inch self. What's more, Charity seemed to be growing. He didn't know what was going on, just that something was going on. He looked up at Charity who seemed to be in her own little world. Her boobs were bigger now... significantly bigger. He remembered when she was only a D cup and now she was pushing E. He couldn't really complain though, as watching them bounce finally pushed him to the edge and he came inside her.
"Oh, baby that was so good," she smiled, the typical glint in her eyes as she caressed her taught six-pack stomach and licked her lips. "Thank you baby," she said, leaning down and squishing his face between her boobs. "Ready to go again?" she asked perking up. Derrick grimly shook his head, noticing how she seemed to be getting taller. Those thighs straddling his hips seemed to widen as space suddenly appeared and separated them.
"Baby... I think we should take a break from... this," he muttered, suddenly feeling smaller and weaker once again. Charity stood up, his member flopping limply out of her. He remembered when her pussy was so tight he was practically stretching her out every time they fucked. Now, he couldn't remember when he last hit her uterus.
"Are... are you breaking up with me?" she gasped, standing upright and looking offended.
"N-no, no, I'm just... I think we should take a break from... you know..." He paused, hoping Charity would take the hint, but she just stared with the same sour expression. "All the sex..." he hissed, almost afraid others would hear him.
"Really? Why? Is it not good enough for you?" she asked, crossing her arms as her boobs seemed to expand a few more inches before Derrick's eyes. He blinked, convinced he was going crazy and hallucinating. "You spent the better part of a year fucking every girl with a pulse because 'Charity won't fuck me, you don't put out, I have needs.' Now suddenly I'm hornier than a porn star and you want a break?!"
"Baby, listen, I'm just... I'm not feeling myself lately," he tried to explain, still laying on the bed while Charity stood against the wall. She looked to be almost six feet, something she claimed was attributed to 'late blooming.'
"Oh baby... is this about my little growth spurt again?" she asked, dropping her arms and giving him a pitiful, if not slightly condescending look. "How many times do I have to tell you, it's okay. I don't care what size you are, I still love you." She took her place back on the bed, laying next to him while supporting her upper body on her elbow.
"Baby, it's not just a growth spurt. I wish it were that simple, but it's not," he scolded, using a knife hand to emphasize the issue.
"Now don't go pulling that attitude with me Derrick. I've done nothing to you."
"Yeah well I'm not so sure about that," he retorted.
"What's that supposed to mean?"
"Baby," he scowled, sitting up and directing his hands to his new physique, "Look at me. Look at this!"
"Look at what?" she asked.
"I'm shrinking baby. I used to be six foot and now you must be five-eleven and you tower over me. My muscle mass is almost gone, coach says I'm probably going to lose my spot on the basketball team and my dick-" He stopped, looking at Charity who cocked an eyebrow. "Charity I measured it just the other day. It's only six inches. I'm shrinking baby and it always seems to happen after we have sex. I'm seriously thinking there's something wrong with me."
"So, you want to stop until you figure out what's wrong?" Charity asked, making the question sound stupid.
"Well... yeah," Derrick answered, crossing his arms trying to look immovable. Had he been standing it would have made more of a difference but sitting on a bed really made him look more like a child.
"Okay," Charity answered.
"Wh-what really?" he asked.
"Of course baby. I wouldn't want to make you uncomfortable. I mean, this is obviously bothering you a lot so, do what you have to. I'll support you."
"Wow... thanks baby."
"No problem hun," she smiled. "But Derrick, would you mind terribly if we just had sex one more time before your break?" she asked, raising a singular finger to emphasize her request.
"For you, baby, anything," he smiled, relenting. "You wanna be on top?"
"Of course," she smiled, Derrick laying down.
CLICK
"What the fuck?!" Derrick shouted as two pairs of handcuffs were locked into place around his wrists and fastened to the bed posts. Charity stood up and smiled down at him maliciously. "Baby what the fuck are you doing?"
"You were right, Derrick. There is something VERY wrong with you. I noticed it back when you fucked that girl Lara. You see, you have been shrinking, quite significantly. Where you were once six foot, you're now five-eight, and while your dick was once nine very proud inches, it's now only six- no... you came inside me so it should now be five," she gloated.
"What the hell are you talking about you bitch?" he screamed, pulling violently at the handcuffs.
"You see, Derrick I've always been smarter than you. I noticed after the second time it happened. When you cum inside me, you lose an inch, and I gain inches. You shrink and I grow. Now, the condoms and pulling out seemed to neutralize the effect, which is why I let you use them, but eventually, your desires outweigh your protection and I take from you more. It was just more fun doing it gradually. But now that you've finally grown a brain, I'll just have to take what's left all at once."
"What the fuck, baby? What do you mean take what's left?"
"Well, you've got five more inches to go so I'd say a good three, maybe four more inches and I should have all you can give me. Bigger tits, four more inches of height, and more muscle. I'll be an amazon that every guy wants to nail. But you'll be that little boy no girl will look at twice."
"No, baby come on don't do this to me," he pleaded.
"Why? You fucked around on our relationship while I became the laughing stock of the cheerleaders squad. That's why I quit you know. So now, I really don't care if you want this or not. I'm taking it." She grabbed his dick and began rubbing but nothing came of it.
"You'll have to do better than that, bitch. I'm not about to lose my manhood."
"That's okay. The medication should be kicking in soon," she smirked.
"Medication?" Derrick whimpered.
"For Erectile Dysfunction. I could sense you were about to do this, considering you didn't tackle sex with nearly the enthusiasm you once had. So, I drugged your last drink and look, it seems to be working." As though by magic he watched helplessly as his dick grew erect by itself. In no time at all Charity was on top of him.
"No baby, stop, please don't do this, I love you, please baby. I promise to do anything just don't take this from me," he pleaded as she lowered herself onto his average manhood.
"Shh, sh, sh, sh," she whispered, caressing his head. "Don't be scared baby. If you be good, maybe I'll leave you with an extra inch." He didn't reply but began to whimper again. "Don't cry baby, look, you've given me such big boobies, and they're about to get bigger. Just watch them grow, it'll cheer you up, I promise. With that she went to work, squatting over him like she was taking a shit but bouncing up and down, centralizing all sensation into his penis. He could feel the drug taking effect as all attempts to control his ejaculation began to gradually fail. After a few strokes he winced and came inside her.
"Ah!" she squeeled in delight, clapping her hands together. "Come on girls, grow for mommy," she giggled as sure enough her boobs seemed to expand and inflate, passing E cup and into double E. Her height increased as well, as Derrick felt himself decrease an inch. "Aw... Derrick, I remember when I was your size," she smiled, now being six feet tall. "Let's see how your little guy's doing," she smirked, getting off of him to reveal his erection had decreased. "See, he's just fine. Giving mommy plenty of nutrients. Let's keep going shall we?" she announced. This time she laid on him, her whole body pressing against his. "Look Derrick, my legs hang off the bed and your face is squished in my boobs. Wanna feel them grow this time?" she asked before bouncing her hips up and down on his member. Just as before he tried to hold on but eventually the medication won out and the felt the blissful agony of defeat as his dick painted Charity's inner walls. "Oh, here it comes," Charity squeeled as her butt seemed to round out more, her legs stretched an extra inch and her breasts began to expand. She made sure to press them hard against Derrick's face, the titty flesh ballooning and spreading up to his nose and eyes. He began to turn red. "Oh, are my titties to big for you to breathe?" she mocked, lifting up to him gasping for air. She got off the bed and laughed.
"Oh baby look at me. I'm the amazon you've always wanted to fuck. Now, you get to. Unless... you really want to stop... psych!" she squeeled, jumping back on his dick. He was only three inches now, barely penetrating her sizeable pussy. Of course, even at nine inches he may not be able to satisfy her. "Looks like I'll have to take special care with him," she whispered, sitting up on his groin and grinding her way to another orgasm. "Oh, yeah, yeah, give me all you got... and more," she moaned as her growth continued. Her boobs were now a bra breaking F cup and she stood six foot, two inches. "Fuck I love this shit!" she moaned as she started again. Derrick held back the tears, knowing that he was one ejaculation from a one inch baby dick. "Come on, Derrick, just one more I promise. This is it! Oh, oh, yes," she squeeled. Devastated, Derrick surrendered, releasing the cream that sapped him and was absorbed by her. She grew, oh did she grow. Her boobs were now a double F, ass big enough to break a melon, and she towered at six foot, three inches. She smiled with glee as she felt Derrick's dick shrink inside her, eventually unable to penetrate past her lips. "Aw... poor little guy," she mocked, looking at Derrick's micro-dick. "He's all tuckered out... but I know what he would like," she smiled. Moving over to Derrick's face she turned towards his feet and assumed a sixty-nine pose. Reaching down with her hand she began to rub the puffy lips sensually while also licking what remained of Derrick's manhood. Small as it was, she had to give it credit, even at an inch it stood erect and proud like a woman's clit. She licked and sucked, struggling to wrap her plump lips tightly around it. Her fingers plunged into her vagina eliciting a moan. Using her fingers she penetrated herself over and over. This would be the last sexual experience Derrick would have: Charity rubbing herself out in his face. She began to constrict, climax was close. She felt so sexy and powerful being so tall, so curvy, and seeing the fruits of her labor. No one would sleep with Derrick, but she would fuck anyone she wanted. The thought of men all lining up with erect cocks in hand excited her and she plunged her fist into herself, finally cumming, spraying herself all over Derrick's face. Seeing his micro dick twitching she dropped her mouth around it and sucked one last time. Much to her surprise, he came.
Her head shot up as she looked down. For the first time since this whole thing started she wondered what the hell she had just done. His dick softened, then shrunk, getting smaller and smaller before suddenly it disappeared. Charity suddenly felt panic grip her. She wanted her revenge but holy shit! "Hey, hey I can't feel anything down there!" Derrick shouted. "Charity?!" She didn't reply, she didn't know how to. Suddenly there was a quivering, and then his groin seemed to shrink in on itself. A slit appeared, flesh around it puffing out, and then a hole. "Charity, whatever you're doing feels really weird," he called. Charity blinked, Derrick had a pussy, or at least it looked like one. She leaned down and ran her hand along the edges before poking a finger inside. Derrick lurched. "Wh-what the hell?" he screamed.
He got no answer except the hysterical laughter of Charity as she dismounted him and went to dress herself. "What's so funny? You ruined me!" he shouted spitefully. Charity tried to fit into her clothes but nothing fit anymore. She had grown too big too fast.
"Well, Derrick, your dick is gone, but it seems you now have a pussy. A fitting end for you, I guess," she smirked.
"N-no way," he hissed. She tossed him a key to the handcuffs.
"Get yourself out, and enjoy your new body. See you around," she smiled and left.
Still giggling to herself she walked down the hall, her skirt so short that her butt cheeks poked out beneath them, her top unbuttoned to let anyone have a peak at her G cups. She knocked on a door, hearing the faint sound of two people having sex. The moans stopped and the door opened to reveal Lara nude and Jethro covering with a sheet. "Mind if I join you?" Charity smiled. With supernatural strength she found herself thrown to the floor by Lara whom she dwarfed. The succubus raised up Charity's skirt and went to work eating her pussy while Jethro sandwiched his member in between her boobs.
