Sarah didn't need to be asked twice. She quickly made her way to the bed and practically pounded on Biff. She was much stronger than him now and her approach had pushed him flat onto his back and she positioned herself kneeling over him, her bulging cock rubbing against his panty covered crotch. The sensation of feeling overpowered was new to Biff but he loved it. He could only squirm with the arousal it was causing him. As he squirmed he felt even more powerless to escape from Sarah's control but that was exactly what he wanted and it just added to his excitement.
Sarah leaned over him and started to gently caress his breasts through his negligee. Biff could only arch his back and moan at the pleasure he was feeling. He reached up to pull Sarah down for a kiss but knew that it would only happen if she wanted it to. Biff had to quickly accept his new role in this relationship. He was now completely at Sarah's mercy. In theory she could do whatever she wanted to him but at the same time he trusted her with his life and knew she would only continue as long as he consented.
The couple shared a deep, passionate kiss, their tongues exploring each other's mouths as their hands explored each other's bodies. Biff didn't hesitate in wrapping his hand around Sarah's engorged penis. He could remember enough from when he had a penis to know it was as erect as it would get and ready for action.
Biff quickly opened the lace string that held the front of his nightie together and let it fall down beneath him. This exposed his breasts to the air and his nipples, already hardening, quickly finished the job. Sarah seemed to be completely hypnotized by his chest. She knew rationally that up until yesterday she had a pair of her own and had seen her friend's breasts more times than she could count. In that life breasts were just breasts, they were part of her life but she never got anything sexual from looking at a pair of breasts. But now, the mere sight of Biff's breasts was causing her already erect penis to strain and spring up with every last muscle. She quickly put her mouth over one nipple and then the other and sucked and licked like her life depended on it. Biff kept his grip on her penis and slowly worked his smaller hand up and down the shaft.
Biff leaned forward to bring his mouth close to Sarah's ear and said what she had been hoping to hear since coming up the stairs. Between gasps and in a breathy voice Biff said, "I'm ready Sarah. Fuck me. Do it now. And don't go easy on me. I can take it. I'm all yours."
Sarah kissed Biff with more urgency and passion than she ever had before. She gently guided him onto his back before kissing her way down his body from his mouth to his lower stomach. She took particular care around his breasts, giving some extra attention to his nipples. She found herself with her face against the delicate material of the panties Biff was wearing. She quickly but carefully removed them and took a few seconds to marvel at the inviting softness that was nestled between Biff's legs.
Biff meanwhile was writhing around in ecstacy, just begging for it. He gently held Sarah's penis and guided it towards his pussy. He spread his legs and when the tip was just outside him he opened his eyes and the lovers made eye contact. They felt as if their souls had connected now and as Sarah began her first slow, gentle thrust they both gasped at the sensation. She slowly pulled most of the way out again before pushing in with a little more force this time. She continued in this fashion, gathering momentum and Biff tried to encourage her but couldn't manage more than grunts, gasps and the odd shout of joy. Sarah wicked the pace and was soon pounding Biff like the newlywed bride he was now. Biff was loving every second and after a few minutes felt the start of an orgasm building. He lost his connection to reality for about 30 seconds while his body convulsed and pleasure spread to every nerve. When he came back to reality he felt Sarah continue without missing a beat. And his own pleasure didn't stop, it just simmered for a while before he felt another climax coming. He managed to verbalise what he was feeling and this was enough to push Sarah over the edge and they both climaxed together in sync.
Exhausted Sarah pulled out of Biff, gave him one more passionate kiss and collapsed onto the bed beside him. Neither spoke, they just lay beside each other panting. Their hands found each other and they silently squeezed each other's hands, enjoying the unspoken connection.
