Sarah wakes up.

Sarah awoke to movement next to her. Her naked body was pressed up against her son's, who had his arm around her. For some reason there were slight vibrations traveling up through his body. Sarah opened her eyes and lifted her head from John's chest and soon discovered the cause: her son and Cameron were in the middle of a very deep kiss while the girl steadily jerked him off.

Sarah shifted against him, then lay her head back down on his chest, the fingers of her right hand drawing random patterns on his stomach. After a few moments the kiss between him and Cameron ended.

"Morning, Mom," he said breathlessly.

"Morning," Sarah replied.

Suddenly Cameron rose up, throwing all the blankets to the end of the bed. Maintaining a firm grip on John's manhood she straddled him, guiding his tip to her entrance, then slowly sheathed him inside her. Sarah felt John tense as her womanhood engulfed him. When she had finally taken all of him into her John relaxed slightly, letting out a long, slow breath.

Sarah sat up against the headboard. "What time is it," she asked lightly.

"7:26," Cameron replied evenly, from her tone it would have been hard to guess that she had almost seven inches of cock stuffed in her pussy. "Do we need to leave soon?"

Sarah shook her head. "Take your time Tin-Miss. LA is only four hours away, and it's not like we have anything we need to be doing."

Cameron nodded. John put his hands on her hips as she began to slowly rock her pelvis back and forth, causing her vagina to shift around him. As she did this John thrust up against her, hissing as she tightened around him.

Sarah watched as they slowly fucked, her own pussy growing wet with excitement. As if she had read her mind Cameron reached out, touching and exploring Sarah's sex. Sarah spread her legs and scooted her ass a few inches further down the bed to allow the cyborg easier access. She felt one of the girl's fingers invade her cunt, her inner muscles quickly clamping down around the intruder.

Cameron began to ride John in earnest, her perky breasts shaking merrily as she rose up and down on his cock. For his part John seemed content to lay back and enjoy the show. Sarah was equally mesmerized, though she did remove Cameron's hand from her pussy and replaced it with one of John's, felling that he should do something to participate.

John almost absentmindedly fingered his mother while Cameron road him. The terminator might lack anything even remotely resembling passion, but god did she have technique. Her cunt rippled around him as it engulfed his cock. When he was balls deep inside her she seemed to stop for a moment, (but the way she was moving there was no way she could have time to), and she would clamp down on him like a vice. A hot, wet, vice. Then she would rise up, her pussy clinging to every millimeter of his cock, fighting to keep him inside her despite her upward motion. And despite the fact that the whole thing took less then two seconds, over and over and over again, every moment, every sensation, every contraction of her pussy felt deferent and unique.

Cameron ran her hands up John's chest, bending over him while maintaining her fast pace. John faintly realized that one of her hands was slick with what he dimly realized mush be his mother's cum. Suddenly Cameron stopped, her pussy contracting around him.

"How tight do you think I can get John?" she muttered in his ear. "I bet I can make you cum with only the muscles in my vagina. Without moving anything else. Do you want to find out, John?"

"This I have to see," Sarah said. John had forgotten about stimulating her, but she didn't mind. Somehow seeing Cameron just sit there, knowing what she was doing to her son but not being able to actually see it was the most erotic thing she had ever witnessed. John just lied there, breathing heavily and letting out the occasional moan while true to her word Cameron remand perfectly still on top of him, their eyes locked as she silently worked to bring him over the edge.

A minute later he came. His eyes screwed shut and he shuttered, his body becoming completely rigid. After a few moments he relaxed, his breathing slowly returning to normal. Cameron remand still for a little while longer, her vagina slowly relaxing its grip on his spent manhood. Then she slowly rose up until his softening cock fell away, a faint trail of their combined fluids seeping out from between her folds and down her inner thigh. Cameron sat down besides him, copying Sarah's position on his other side.

John stirred. "I'm going to go take a shower," he said after a moment.

Sarah nodded. "I'd like to talk to Cameron. You go and get cleaned up."
