Marge is getting too aroused by the situation to deny her own arousal anymore. She lets go of Lisa's head and sits back in the couch, spreading her legs. Bart saw the show his mother was giving him and got even more excited than he already was. His lust overtook him to the point where he forgot that the sweet, hot hole he was fucking was in fact his sister's throat. He kept fucking her face hard and fast as he looked at Marge mastubating with her legs spread wide. Bart's cock stayed deep down Lisa's throat, chocking her even more with each passing second. Eventually Bart noticed that there was no more fighting or resistance of any sort from his sister. He looked down at her and realised that she was about to faint. Reluctantly he slid his throbbing dick out of Lisa's mouth and allowed her to fall limply on the couch.
Since he didn't have time to cum in Lisa's mouth, Bart is still fully erect, throbbing and close to shooting his load. Marge has her eyes closed and she is still rubbing her clit furiously, while Lisa is slowly catching her breath, sprawled on the couch. |
