Goes back inside.

Mark decided to just head back inside. There was no more Nick. There were only two redheads the required his attention. In the house he found Ashley arms folded staring at his mother's back. She was back in her teddy but was still missing her thong. The teddy was barely long enough cover her up and he could clearly see her ass and pussy peek through under the short lacy hem. His mother was frozen in mid-stride her back to the living room.

"Well..." Mark started to say as he unfolded Ashley's arms is raised them up. "You're practically naked so..." he added looking at Ashley's blank eyes as he started to work the teddy northward.

Soon Ashley was naked once more. She stood posed with her arms raised in front of her like a zombie, the look worked considering how blank her face was. Mark admired his sister's nudity and pose before he turned his attention to his mother.

"Time to join the party..." he said as he spun the older redhead around. Robin's arms were raised and Mark started to work the tight-fitting compression top off of her. Her naked breasts soon popped free and he eyed them as he tossed the top aside. Robin has perfect sized breast capped with pink nipples that stood hard and erect. He played with them a bit before his eye went wide. "Fakes!" he blurts as he looks at them closer and then at his mother's blank face. "When did you get fakes..." he asks but was not expecting an answer. Shaking his head he moves south and pulls down Robin's shorts. He was not surprised that she had no underwear underneath. He gave her clit a quick fingering before he got her naked the rest of the way removing the shorts completely and then taking off her sneakers.

Robin soon stood next to Ashley mirroring her pose. Mark looked between the women, ideas were swirling in his head. In the nude he could see the resemblance. Taking in their poses he started getting hard.
