Stepsis has been becoming more and more sexually aware lately. She was too scared to experiment with a boy, so she has started slow and just been rubbing her pussy on her pillows and stuffed animals. One day when she was really getting into it, her stepbro walked in on her! She thought he was perving out until she realized he was unconscious. Then she remembered her stepmom told her of his sleepwalking problem. She threw him on her bed and decided that he would be just as good as a pillow, only a little bit more advanced ;). Charity rode and sucked her first ever real boy cock, and boy was it much better than a stupid pillow! If only stepbro was a little more into it and not so tired. Damn was that good, and even stepbro enjoyed it in his dream state, making this the most wettest dream he has had all year!
