Cum in her throat

James' breath grew quick as he approached what was about to be his greatest orgasm to date. Even as his sister's throat struggled to get air around his cock, the feeling of that **** suction was driving him wild.

He didn't care if she couldn't breath he just needed to cum.

He couldn't control himself any longer. His entire body shook and he bellowed out as his cock began to unload. The feeling so intense it bordered on painful as he fired shot after shot of scalding seed directly down his sister's gullet.

Looking down, James realized he had been squeezing Courtney's breasts so hard he'd left sharp red marks on both of them, sure to bruise. As his cock shrunk and fell out of her throat he looked at what remained of his sister. Her breath was shallow and she was completely ****. She was an absolute mess. A mix of snot, semen, saliva, make up and sweat formed a thick film of filth all over her face. She was nearly unrecognizable from the pretty teen future valedictorian she was just a little while ago.

James staggered backwards, steadying himself on the sofa. His mind reeled from what had just happened, from controlling his sister to that mind shattering orgasm.

He could hear his sister's thoughts, even ****. It was a whisper, but he could hear it. She was babbling crazily, denying the reality of what had happened to her. He smiled to himself, she had no idea what was to come.
