The next several minutes went by quietly, the silence broken only by an infrequent soft slurping sound or a restrained noise of pleasure. Ellen's mind kept toggling back and forth between visions of fellating her son and remembering that she was supposed to be pleasing her husband as best she could. In front of her, Victor was fighting a losing battle against the imagery of his daughter being the one with his hard cock between her lips, and the shame and arousal he felt from it.

A short distance away, Carla was occupied with enjoying the feel of her brother's mouth and tongue doing such wonderful things to her pussy and clit while fantasies of sucking her father's cock played through her mind… and further fueled her passions. Between her wide-spread legs, Robert was busy cycling between trying to stimulate his sister into producing even more of her nectar for him to lap up, and stealing glances over toward where his mother's head was bobbing back and forth on his father's shaft while his own penis continued to grow longer and harder.

The silence was finally broken when Vic lost his fight to keep the images of his daughter out of his mind; with a deep groan, he began erupting into the warm, wet cavity his dick was in. His release was made even more intense by the thought that it was Carla's mouth, and not his wife's, that was receiving his cum.

Even though her eyes were closed at the time, Carla knew that the sound she heard was her father; almost immediately, she knew it signalled that he'd reached his climax. Knowing that he was cumming, it was easy enough for her to imagine that hers was the mouth he was filling with his cream- particularly since she still had the taste of her brother's semen still on her tongue. The visualization of his cock spurting in her mouth was enough to push her over the edge into the strongest climax she'd ever experienced.
