You both sleep

From Torg Adventure

Your releases get the better of you, and you both fall asleep. You dream that you are the one in charge, not your father, and your mother sleeps with you. She gets out of bed and you realize she's pregnant. She berates your father for being unable to knock her up, while her son had to do the deed.

You wake up in the dark, hard from your dream, and your mother is still sleeping next to you. Thinking over your interlude, you think she would be amenable to going farther, so you decide to wake her up in the best possible way -- oral sex. She's laying on her side, so you roll her on her back. You get out of bed and crawl up between her legs. Her pussy smells wonderfully musky. She definitely got hot last night.
