One hot bitch

Sean's stepsister, Brianna, drove him crazy. She was a hot bitch who, when she wasn't ignoring him, was teasing him. She knew he lusted after her, and she walked around in skimpy clothes just to tease him.After watching her waltz around in a skimpy skirt and skintight top, Sean would disappear into his room for a quick bout of quiet, desperate masturbation. He so wanted to spite fuck the hell out of her.
So when Sean found a magic spell that would let him swap bodies, he schemed to use it on Brianna's boyfriend so he could finally have his way with her. The instant he finished the last word the world spun.
Suddenly, he was on his knees straddling Brianna's boyfriend. That in itself wasn't right; Sean should be in him not on him. Something warm and hard-soft thrust up into Sean, bringing with it a deep aching pleasure. Long, dark hair whispered down Sean's back and his little tits(!) bounced as Brianna's boyfriend gripped Sean's hips and thrust up into him -- into his pussy. Shit, he was in his stepsister's body.
Sean gasped and half-turned, grabbing the plump butt beneath him in shock, his fingers dimpling the fat flesh he'd coveted for so long. Just not like this. He tried to climb off but her boyfriend took it as a sign that he wanted more and he thrust up into Sean's wet folds.
Sean cried out as unwanted pleasure spiked through him, Brianna's body already so warm and aching with need. The cry from his lips was tiny and feminine, echoing the sound from his fantasies and it pushed him over the edge. 
Sean sank back down and gripped the back of the couch, begging for more, as Brianna's boyfriend suckled at his tits and thrust up into Sean faster, faster, until he exploded. Sean gasped as the delicious heat filled him. The gasps quickly turning to moans as he enjoyed Brianna's stolen orgasm.
He'd have plenty of time to enjoy more of her orgasms, because he was now sealed in her body forever.
