Mike was really getting into it. He could tell some things were off, but it didn't matter to him now. His mind was starting to be flooded by visions of Rachael. She was standing there in a field of grass on a sunny day. Her butt was much bigger than he remembered it. She was smiling and motioned Mike to come closer. As he approached her she started to turn around and lean forward. Rachael raised her rear into the air and bent over, her jeans split at the seams exposing her butt to Mike. Mike could also see her swollen sex just begging to be penetrated, but that wasn't all. On her newly exposed flesh she was growing a short coat of chestnut fur and a small numb started pushing out from her tailbone. The remnants of her pants fell to the ground in tatters. The fur was spreading fast and soon covered the entirety of her legs and was rapidly covering her abdomen. Rachael started to pull her top off and Mike reached out and..
"HEY!"
Mike Snapped out of his blissful trance and tried to take stock of the situation. "Mike! What are you doing?" It was Rachael, "I can see you've missed me, but let me clean this up." Reality slowly dawned on Mike as he realized that what he had seen wasn't real. In reality he was leaned over his girlfriend, his dick pressed tightly against her, about ready to start humping.
'Were the changes real?' He wondered and looked down to his crotch. 'Yep, that was almost three times the size it was supposed to be. Why didn't Rachael freak out?'
Rachael was bent over fiddling with something on the ground. She continued to speak as mike dismounted her. "I can see you found that bottle I left for you in your bag? I put a little something extra in it to help with your little size problem. I didn't think the effects would work THAT well though, you're huge! Sorry about the mess here, I dropped my paperwork and I can't let this get mixed up." She hurriedly tried to finish putting all the loose papers into an organizer. "If you want, I'll meet you in the bedroom in a minute. I'd say don't start without me but I can see you already did." Mike didn't need anymore coaxing then that and he was off to the bedroom.
Mike barely noticed that his hair was longer or that he had to duck slightly going through the door way. He also didn't notice that he couldn't quite feel his feet or that he was feeling a lot warmer all of a sudden. None of that mattered right now, he wanted Rachael so badly. Mike had a long history of disappointment when it came to his sex life. He wasn't the most well endowed and wasn't very good at making up for it, but tonight he felt fantastic. His confidence was brimming and he couldn't wait to finally show Rachael the time of her life.
Rachael, meanwhile, had just finished gussying up after stacking her folders on a table. She was really excited, it had taken a lot of willpower not to turn around earlier and jump on her man. She wanted to do it right tonight and the way he had started earlier didn't give her the chance to really get ready. She liked him a lot but he had never really been able to fulfill her before. That's why today she had put some male enhancement pills in a drink and replaced his water with it. Rachael's mind drifted to the feeling of Mikes shaft as he had brushed it over her moments ago. It had felt huge and just the thought of it now had Rachael turned on. She could feel herself getting wet with excitement. It was time.
Rachael opened the door to be greeted by darkness. A solitary candle burned from the safety of a nightstand. "Hey babe" Mike said trying to sound seductive. He laid on the bed one hand reached out to invite Rachael to join him. "Oh Mikey!" Rachael swooned taken aback by the candle and rare confidence being shown by her boyfriend. The shadows were long in the room and Rachael didn't even notice Mikes slightly pushed out face, the fact that he only had two fingers on each hand, or the fact that an even darker shadow was spreading up his legs.
Rachael sauntered over to the bed and straddled Mike's abdomen. Leaning down to his face, she planted a kiss on Mikes lips. They felt a little puffy to Rachael but she wrote that off as a wound suffered in his competition today. Mike kissed back, nibbling her lips gently. Rachael reached her hand up to the back of his head and squeezed their kiss tighter. Their tongues intertwined in a deep french kiss. They continued to make out while Mike started pulling her shirt up her body. Mike took the time to caress Rachael's body as he did so, his more clumsy hands gently gliding over her curves. They broke off the kiss as Rachael started taking off her pants and panties. Mike finished removing her top and threw it out of the way. Rachael reached down from her perch on top of Mike and found his member. She started stroking it, feeling it's substantial girth. In truth Rachael was a little scared it might be too big now but she was too lost in the feelings of the moment to let that bother her. She positioned herself over the tip and slowly lowered herself onto Mike's large shaft. He was indeed huge, she had taken all that she could and there was still more. Rachael slowly started to ride Mike, taking as much of him as she could. Each thrust sent miniature shock waves through her body. Mike started to buck in time with her forcing himself even deeper into her folds. Mike couldn't believe how good it felt. He couldn't believe how tight Rachael felt to him now that he was so well endowed. It was amazing. He was filled with euphoria but somewhere at the very back of his mind he could tell something was off. His feet were now complete horse hooves and his legs had reformed to provide a more unguligrade stance. Fur had also covered his entire lower half and was spreading up his back around his sides and over his shoulders. The fur traveled around his body and the muscle underneath began to expand. If he had been wearing a shirt it would have been torn to shreds simply from his new muscle mass. Finally his ears tugged up and his face pushed out a little further. It was at this moment Rachael looked down from her position above him and finally registered the changes.
Rachael instantly stopped thrusting and tried to focus "Are you ok Mike? What's wrong with your face?!" She blurted out.
"Oh, don't stop Rachael, what are you talking about?" Mike asked not entirely sure what she was talking about. Mike continued trying to thrust into her but realization was finally dawning on his girlfriend. "Y-y-you have horse ears! A-a-and fur! A-a-and your face looks different!" Rachael was starting to freak out. She quickly jumped off of Mike and hurried for the door. "What are you?! What happened?!" She yelled as she quickly fumbled around for any semblance of clothing. "You're turning into a monster!"
"I didn't do anything Rachael, what are you talking about? It's me, Mike." Mike responded. He got up as quickly as he could but couldn't find his balance on his new hooves. He fell over in a heap on the floor. Rachael was already halfway to the apartment door. She stumbled trying to put her pants on and finished throwing on a shirt. Quickly she made a run for the exit. Mike tried to follow but just couldn't adjust to his new stature in time. Mike could hear her car door slam and the engine start before she peeled out of the parking lot. She was gone.
Unfortunately for Mike the fact that Rachael had left did not relieve him of his need for release. Mike grabed his engorged member and tried to resume his pleasure. Mike was now out of his trance and could feel everything happening to himself. He could feel the last bits of dark fur cover his chest and he could feel his tongue lengthen and fall out of his mouth. He even relished the feeling of his new tail swishing this way and that. He felt amazing, so what if he wasn't quite human anymore? Now he was more than human. Mike finally came with a huge shudder and his load shot all over the apartment. It spewed everywhere and just seemed to keep going and going. "Rachael has no idea what she just missed out on" Mike proclaimed right before passing out.
