Your parents are so cheap! They couldn’t even spring for a place with two bedrooms, so you and your sister are stuck on a little pull out bed on the floor of your parents room. Of course, you don’t want to go to bed when they do, but you’ve got no choice–their rules. So stupid. You and your sister stay up goofing off, being ridiculous…when you get an idea. You dare her to play a version of the "Penis Game," directing your silly words and phrases at your parents, in bed just feet away. You start easy: yell penis, tits. Then you go further, knowing your sister won’t back down. She’s always down for a dare. You have her flash your parents. First her tits, then her pussy. Your cock is getting so hard watching her do it, so you keep going: finger your pussy and call dad’s name, you tell her, and watch as she obliges. You can tell she’s getting excited. You can hear it when she plunges a finger into her wet pussy. You want to reach over and grab her by the face, pulling her throat deep onto your cock–you’ve heard the rumors at school, about how sloppy her skills are, how dirty she gets–but instead you make it her move. You dare her to touch it, your rock hard cock…and from there, you know there’s no turning back. Bettie isn’t one to back down from a dare, even if it does mean swallowing her brother’s semen.
