has left the doorway

Matt could have sworn Nate would have entered the kitchen, but the look around proved that was not the case. She walked to the door, peering around the doorway, her breasts pressing against the jam, and for the first time, the reality of the breasts connected to her body. One hand strayed up to feel the soft mound, and Matt smiled. Apparently, his mom didn't always wear a bra around the house.

Keeping a lookout for any movement, Matt's hand slid down her side and between her legs, feeling her sex beneath the skirt and panties. Even though Matt was using borrowed fingers, the thought that the pussy beneath those fingers was the same one that gave birth to him sent a thrill through his mind.

She rubbed her pussy for a few minutes, reveling in the thrill she felt with each stroke, fingers easily finding the small nubbin of her clit beneath the cloth. There was no movement or sound throughout the downstairs level.

Matt could only watch as Nate thrust his cock into his eighteen year old daughter again and again.

With a final thrust, Matt realized Nate was trembling with orgasm, filling the girl with sperm. No, Matt corrected, using the memories of the body. Nate had gotten fixed soon after Matt and Lily were born, so they wouldn't run the risk of yet another child. That wasn't the only realization Matt had, however.

The second realization was that Helen had seen this activity before, and Nate knew she had seen. Seen, and not done anything.

Matt jumped back, trying to process what he had seen while inside his mother's mind. It was only as he lay there that he realized the look on Lily's face, at least the part that he could see over their father's hand, was one of pure...
