My pet/toy Alyssa stood seductively before me in all her buxom glory, hands on her hips, a playful smirk on her lips. She practically begged to be fucked.
"Alyssa," I commanded, "I want you to take my pants off."
The girl's face brightened even more. "Yes, Joe!" She said enthusiastically, and kneeled down in front of the armchair, her face level with my crotch. Her hands reached up my legs, slowly running their manly contours, and her hands slid over my thighs towards the bulge in my pants. She paused and looked up at me with wide eyes, in a sort of 'what do you want me to do now' expression.
"Keep going." I smiled, and leaned back into the chair in bliss.
Alyssa's feminine hands purposefully slipped over the bulge in my jeans, caressing my member through my clothes for a moment, before her hands reached up and unbuttoned my pants. She grinned wider, having felt my length and girth, and gently pulled down my zipper.
"Yes." I whispered.
She pulled my pant legs off and removed my jeans, leaving me sitting with a massive boner in my tighty-whiteys.
"Keep going." I whispered.
My slave complied with gusto, removing my shorts with not so much care. She was horny, I could see it, and wanted my dick. At last, my seven inch long and two and a half inch thick penis sprung up to slap my abs. Alyssa practically licked her lips in amazement. "So big..." She whispered.
"And all yours." I finished. "Suck me."
Alyssa blushed deeply, and closed her eyes, grasping my penis in her hand and holding it as she extended her tongue and gave the underside a smooth lick from base to tip.
"O-Oh god!" I moaned, and leaned back further.
She licked again, and again, and finally harder. Her tongue was soon licking my tip, around it, tasting shaft. I trembled in pleasure as her warm soft lips took me into her mouth, and she began giving me the best blowjob of my life.
I opened my eyes to see the dark haired slavegirl sucking me off, and it felt amazing. I was already horny, but her steady sucking and slurping was driving me insane with delight. To my amazement, I saw Alyssa's other hand caressing her big tits and pinching her nipples.
Those big perfect breasts. "I wish your boobs would get bigger and fuller."
Alyssa's eyes widened in alarm and I saw her grin with my cock in her mouth. Amazingly, she never broke her rhythm and kept sucking. She trembled for a moment and her other hand began massaging her breasts more. I watched with astonishment as ever so gently they began to expand, pressing forward and outward like inflating balloons. Alyssa kept sucking, even harder then before, and I felt my orgasm approaching fast.
I watched with delight as she grew while sucking me, her big full orbs even larger and rounder. She had melons before, now they were getting to be as big as basketballs, with pert inch long nipples and big round areola. She moaned on my cock and squeezed her left tit, clenching it as it surged forth in her hand, the breast flesh beneath ballooning and ballooning with meat instead of air.
I came. Hard. I cried out in delight and threw my head back as I whited out with burning pleasure. Five or six ropes of thick semen squirted from my cocktip and into Alyssa's eager mouth. She sucked harder, bringing my orgasm to a dizzying height, and gulped my cum down.
I opened my eyes finally, panting and exhausted, as Alyssa drank the rest of my cum and parted her lips from my cock, letting it go and licking her lips. Her cheeks were flushed red, she looked feverish, and both of her hands were now on still growing watermelon sized breasts that were so big and heavy the poor girl could barely stand up from their weight. "Oh, Joe..." She said lustfully. "You taste wonderful. And my tits are getting so huge and sensitive for you."
"I like watching you grow." I admitted, and joined Alyssa on the floor, my hands caressing her enormous boobs and nipples. She moaned, and leaned forward to kiss me, pressing still amazingly firm breasts into my chest and neck. We began embracing, kissing, touching. Soon I was hard as steel again.
I pulled Alyssa down to the carpet and placed her on her back, lying on top of her. She moaned deeper, still kissing me, and I plunged my hardened penis into a wet well lubricated pussy. She felt incredible, her breasts were still growing, and we started to fuck. With every thrust of my hips her enormous boobs bounced and jiggled on her chest, pressed into me and getting bigger by the second. I wrapped my arms around her back and held on tight as I gave her everything I had.
She squeeled suddenly and cried out. "Oh God! I'm cumming! I'm-- aaahhh! Ahhhhhh!" I felt her clench on my cock and grunted as I blew inside of her, the orgasm intense.
I opened my eyes, covered in sweat, and stared in disbelief. Her boobs were now easily the size of an overinflated punch balloon - each, and were parted on either side of her, massive and heavy. Still they grew, and from Alyssa's delighted satisfied face, she didn't mind.
"Ohhh." She moaned, and broke into a giggle. "This is wonderful, but I fear I won't be able to get up again."
"Who needs to get up?" I laughed. "But I wish your breasts would stop growing."
With almost relief, Alyssa let out a contended sigh and her eyelids grew heavy. "Come sleep with me," She offered. "You can use me as your own personal bed."
I grinned, nuzzled my face into one of Alyssa's giant breasts, and we spooned. I was starting to feel a little tired myself.
