Dealing with Sister

Mark could see and feel that Sarah was starting to feel good. He saw it in the way she breathed and how her pussy tightened around his hard cock each time he thrust inside her. Her hips even started to move to meet his thrusts. He wasn't sure if it was to make him come quicker or if it she did because she wanted to reach her own orgasm. Either way it felt even better as she started to take a more active role and soon Mark was sucking on her nipples while their hips slammed into to each other. It wasn't just him who fucked her now; she fucked him just as much as he fucked her.

She didn't hide her moans anymore and the way her pussy squeezed his cock made it very difficult for him to hold back. Mark could feel how his orgasm was approaching quickly and he started to thrust more rapidly inside her. He had a hard time keeping a steady rhythm as the tingling feeling in his cock became too much. His whole body screamed for release and he could see it in Sarah's eyes that she needed it too.

"Don't come yet, just a little longer. Fuck. I need to come," Sarah said. She struggled with her speaking, overwhelmed by the pleasure of her brother's cock.

Her moaning got louder with each thrust and soon it became impossible for Mark to hold back. He tried, but eventually it became too much. As soon as Mark knew he was about to come he grabbed Sarah's hips and thrust in and out of her as quickly as he could and right before he was about to come he felt how her pussy contracted on his cock and she let out a huge moan. Moments later it all became white, the feeling of her contracting pussy pushed him over the edge. Mark buried his cock as deep inside her as he could before the orgasm overwhelmed him.

Mark held on to her hips with all his might while his cock pumped his seed inside his sister. It felt unlike any other orgasm he had ever had. The feeling was unmatched and hearing his sister scream as she came was part of the reason. He released more cum inside her as he continued to come.

They had done something he would never forget. Even as he started to calm down after the orgasm he still felt no regrets. It had been more amazing than he ever thought it could be. He sought out his sister's lips once more and this time she kissed back. It was a short and sensual kiss, but he could feel that it meant the end.
