Kat wasted no time getting naked, and once she'd pulled off all her clothes she practically leapt at Dan, pushing her to the floor and making her flustered as hell. She felt Kat's boobs squishing against her own and their wet slits rubbing together, her legs having been pushed apart by Kat's. The girl kissed her, tongue pushing into Kat's mouth, and she felt the air run out quickly, gasping for air once Kat pulled away.
"So, ready?" Kat purred, not caring to hear Dan's answer. "Time to fuck you up!"
Dan felt her crotch grind against her own, and she yelped in surprise as the other girl's hard clitoris rubbed along Dan's own. Kat's nipples were sliding against Dan's almost in sync, and that only intensified the weirdly arousing feelings of Kat fucking her. Her motions seemed to grow more eager as she continued, and when she kissed Dan's neck the transformed girl moaned loudly at the heightening of the sensations.
Kat was in heaven as she continued grinding at the adorably helpless girl under her. She'd humped her pillow so many times imagining getting to do this (and similar stuff with guys, but there wasn't a chance in hell she'd want Dan to do anything to her as a guy), and getting to live out the fantasy was just as amazing as she'd imagined. The softness and wetness of all of it was intense, and she knew it wouldn't be long before it made her peak.
By contrast, Dan had never even imagined this, but that made it feel weirdly good for her too. To think he'd gotten so emasculated that another girl was topping and fucking her- but the way her body rubbed against Dan's made her feel amazing, and she moaned just as readily as her lover.
Before long, they both felt their climaxes racing towards them, and kissed sloppily and moaned into each other's mouths as they came hard, slick juices mixing on their pussy lips while their nipples and clits pulsed against each other.
While Dan lay there in a pleasured haze, Kat thought of another wish she wanted to do...
