This choice: Shelby grew a couple feet • Go Back...Chapter #5Bigger Shelby by: SLI201   Shelby climbed onto her knees and hugged her midsection as I put my hands on her shoulders, gasping as I felt the intense heat emanating from her flushed skin.
"W-what's happening? Shelby?" I asked tearfully, concern cracking my voice. "What are you feeling?"
"I...I f-feel..." Shelby stammered quietly, her head bowed so I couldn't see her face, but she started panting quite heavily and her arms relaxed. "...really good!"
I stared as one of her hands reached up and gripped my arm as Shelby shuddered and started to grow right in front of me, my room-mate grunting as her body expanded on the bed. As I continued watching, completely lost for words, I felt her shoulders rise higher and higher while she lifted her head and tilted it back, her eyes glazed over and far away, a euphoric grin plastered across her face. Sweat glistened and ran down her bare skin as she kept growing bigger, her tits gradually rising to meet and then move above my eye line. The sounds of Shelby's erotic groans and the sight of her swelling larger right in front of me started to rekindle my lust and I felt my fresh cock twitch and harden again, swelling and thickening to its former 12-inch glory.
Shelby heaved another delighted grunt as her body trembled to a halt at just over seven feet in height, her eyes fluttering and clearing as she gazed down at me, her grin shrinking into a coy smile as her eyes latched on to my member now at full attention. Before I could react she lunged downward and pressed her lips against mine in an urgent, passionate kiss, her hands starting to rub my back.
"Well, that was fucking fantastic," she breathed as our mouths separated, a gentle whimper the only sound I could make as her larger hands firmly grasped my shaft. "I want to feel that again!"
"S-Shelby, wait-ungh!" I groaned as she started massaging my cock, my mind exploding with ecstasy at every pump and my entire body going limp as the euphoria blazed red hot through my mind. I could feel something happening with my new sex-organ, a gentle heat pulsing through my groin that felt different to the orgasm from before.
My lust-crazed room-mate ignored my feeble slaps of protest as she positioned her enlarged self above my dick, her sex pouring juices down her legs as it hovered above my twitching cock and her lower-lips kissing the head as she displayed incredible leg strength in holding the position, her eyes boring into mine. My concerns had been washed away in a flood of lust at this point and my hands gripped her thighs as I tried to lower her down, growling in frustration. Shelby smirked, as much as she could while panting, anyway, and slowly, slowly, lowered herself and let me enter her a second time.
My eyes rolled up at the stimulation as she now comfortably swallowed my entire length into her folds, my cock buried right up to her crotch. A groan erupted from her as she rested her full weight against me, her legs now lying flat across the bed, and sat still for several seconds while teasing me with little twitches of her hips, the stimulation only feeding the mysterious heat building in my crotch. Suddenly I felt the ecstasy intensify and I groaned loudly as I felt my cock start to grow even larger, thickening and lengthening to reach even deeper inside Shelby as she shrieked at the sensation and looked down. Just as a barely-visible bulge started to form on her body my growth stopped, leaving it at least four inches longer.
"S-Shelby," I groaned weakly as I could feel the orgasm rapidly approach, her vaginal walls flexing against my entire length. "I can't hold on..."
My giant room-mate reached under me and pulled me up to meet her, kissing me hard before resting her larger forehead against mine and blowing a whisper against my face.
"Fill me, Mandi."
The combination of her eagerness, lust and expression that close drove me over the edge and I went completely limp as my release crested, Shelby pulling me into a tight hug as we both shuddered in a combined orgasm, my massive cock twitching before erupting with great long spurts of hot cum, quickly filling her womb and then more, causing it to stretch and expand. She cooed in my ear as I drove my hips against her with every spurt, completely enslaved by my mind-shattering climax, her belly slowly but surely bulging out against mine. Shelby started to nibble my ear as my dick showed no signs of stopping, spurting endless ropes of cum into her expanding mid-section.
Finally, after several minutes lost to complete and utter ecstasy, I gradually came back to my senses to find Shelby's belly swollen to the size of a small melon, my room-mate tenderly licking the sweat off my neck. I giggled breathlessly and returned the favour, peppering her shoulder with kisses before our lips met again and we shared another passionate one.
"H-here it comes," Shelby stammered as I felt her body tremble and flush red with heat again...
