For contributors As was stated at the top: while there were will be two general threads to go off of (for a guy and girl), feel free to create your own characters or scenarios. The only shared premise among them needs to be that they find themselves, however you decide that happens, in this universe and, as The Eagles would say, "You can check out any t...

I asked Lexi, my lips practically tickling her ear as I formed the words. Our arms were around each other's shoulders, linking us together and allowing us to whisper our conversation such that it would, hopefully, not be over...

Christa grinned as she tore aside the tattered remains of Kasey's suit, exposing her luscious round posterior for the world to see. She clapped her hand down upon one of Kasey's globular ass cheeks, watching the fat and muscle jiggle as a red hand imprint formed. "This ass is mine, girl." Christa growled, aligning her 3 foot erection with Kasey's dripping w...

Author's Note: Alisa and Bianca are a happy couple together. One is an underdeveloped futanari and the other is a stacked babe respectively, but a night out, and some drinking, changes that. For better? Or for worse? * Alisa moaned softly into her girlfriend's lips. She felt so hot and tight, yet smooth like velvet as Alisa was bathed in her pleasure. Alis...

Tuesday and Wednesday soon passed. Two days since Carmen wrote Mary's name in the book and transformed her, entirely out of a desire for revenge. A desire that was left unsated. Mary hadn't changed in the slightest, not in any way that Carmen could discern. She remained as narcissistic and hateful as ever, tormenting anyone and everyone who crossed her path....

The wait exasperated everything. Carmen's sharp and heavy breaths, the thudding of her heartbeat in places she wished it wasn't, and the rush of air on her skin all seemed too focused. She listened to the clamour of customers outside, footsteps passing to and from the door, always alert for the dreaded knock. And yet, in spite of that anxiety, her cock stood...

Whatever expectations she had were shattered. Pleasure was no stranger to Carmen anymore since masturbating daily, nor was oral from her time with Stacy, and the infrequent blowjobs Ryuka snuck upon her, but this shocked her to the core. Moans trickled from her mouth like sweet nothings. She stared at the ceiling, hoping to reconcile reality with the sensati...
