STANDARD DEFINITION VERSION. Part one of MILF886. Rachel's step-son Aaron is a total geek and fancies himself an inventor. So far he has not invented anything practical or useful but Rachel does not want to discourage him. His step-sister Misty loves her step-brother but would rather not be seen in public with him. He is pretty embarrassing when you are trying to be cool. Misty calls out when she comes home. Aaron is in his room as usual working on some stupid gadget. He is excited and tells her that he thinks that this one is going to be a big hit. It is a device that stimulates brain functions. It could help people with learning problems overcome brain injuries. He asks Misty to test his invention. She asked him if it was going to fry her brain. He told her that there would be no problem. He attached the collar to her neck and inputted the first instructions into the remote. She felt a little jolt and reacted. He told her that this was normal. He punched in the second set of instructions and gave her some simple directions which she followed to the letter. He knew it was working because Misty never did anything that he told her to do. He punched in the third set of instructions when it stopped going according to plan. Misty started touching her crotch and breasts. Aaron looked at the remote control and tried to figure out what went wrong. It suddenly occurred to him that this was a chance for him to have real sex. He looked around to ensure that his step-mother was not home. He told Misty to take off her sweater and pulled down her dress to expose her young breasts. She took it off and resumed playing with herself. He dropped his pants and told her to suck his cock. She bent over and took his cock in her mouth without any objection. She continued to suck his cock until he instructed her to lie back on the bed. He spread her legs and pulled her panties to the side. He played with her pussy and she almost immediately had an orgasm. The device had made her clit extra sensative. He told her to play with her breasts while he played with her pussy. He was so horny that he told her to resume sucking his cock until he load of cum down her throat. He removed the collar and found to his surprise that she still responded to his commands. That effect was permanent! He knew that his step-mother would be home soon so they went into the living room to wait for her arrival.
