Fuck No - Keep Going

Aaron's initial disgust at tasting his own dick (albeit with his sister's tongue) was overridden by the pleasure of taunting his sister.

Forcing her lips apart again, Aaron positioned his hand and began slowly inserting the entire length of his dick into Natalie's open mouth.

The warmth of her sent a thrill down his crotch, up his spine and into his arm, and he could feel Natalie writhe, caught in the conflict between her disgust and arousal. The deeper he pushed into her, the more she squirmed, but the sensation was delicious so that even as she lost herself to lust, her mouth and tongue didn't stop wriggling.

Finally, finally, Aaron felt her lips come to rest at the base of his cock and stopped pressing downwards. The sensation of his dick snugly buried in his sister's detached mouth was heaven, and he wondered if she was daring enough to try and bite him.

The sensation of teeth against his skin made him jump, but again the sensation was transmitted to Natalie who let go quickly. It was clear that whatever she did to Aaron while in this state, she would have to suffer through it.

Rather than try to hurt him, Aaron eventually felt his sister's trapped soul grow impatient that nothing was happening and began to reluctantly suck on his cock. Gently at first, but with increasing vigour as the pleasure grew. Aaron lay back, hand against his crotch and basked in the sensation, doing his best to ignore the feeling of a cock in his other mouth and instead focus on the mouth on his cock.

The sight of Natalie's body staring glassily into space just feet away from him filled his mind with all of the things he could do now that she was at his mercy. The debased images flashing through his mind's eye and the steady sucking on his cock brought Aaron quickly to orgasm, and he could taste his own semen squirting into his sister's stolen mouth.

Even after cumming, Natalie continued to suck and Aaron's body began to convulse, too overcome with pleasure to make her stop. It wasn't until he was **** to climax a second time, his oversensitive cock firing blanks, that Natalie's mouth finally released him and Aaron collapsed in bed, exhausted.
