Video Description: Dakota Tyler rushes into her bedroom and screams into her pillow. Her older stepbrother Jason Pierce comes inside to see what's wrong. It's not fair! The double standard, Jason, if we put out then we're a slut, if we don't we're a cock tease, and if we don't let them touch us at all we're an ice queen. There's no instruction manual for a girl to know what they're supposed to do. We always lose, she exclaims. Where's all this coming from?, Jason asks.

Video Description: Tyler Cruise pulls up his pants, as he and his stepsister Kyler Quinn get dressed. You have to promise me something, she says. Not to tell anyone?, he asks. Well that, and you have to promise to never see Liz, she says. Uh..., he pauses. Pinky promise, she says, and they wrap their little fingers around each other as a pledge. Kyler leaves the bedroom, saying Bye. Later, Tyler is doing jumping jacks in the living room when Liz Jordan arrives and knocks on the door. He opens it, and she says Um, you don't have to do that on my account, as he fumbles trying to put on his shirt. Is Kyler home?, she asks. Kyler?, he says. Your stepsister, dummy, she responds. I know, but no, she isn't, he declares, adding I'll let her know you stopped by. Well, aren't you going to invite me inside?, she asks...

Video Description: Coco (Lovelock) and her cousin (Theodora Day) argue about an upcoming birthday party for a guy she's got a crush on, when Coco's stepbrother (Jason Pierce) enters the kitchen, just as Coco storms off in a huff. Theodora fills him in on the argument and flirts a bit, but then runs off, after agreeing that Jason can help her with her trigonometry homework tomorrow. Coco returns after the birthday party and plops down on Jason's bed, telling him what happened. With mascara running down her cheeks, she relates how birthday boy Dirk was with her all through the party, getting drunk. After she kissed him, he got fresh and tried to force her to give him a blow job. She screamed and he ended up throwing her out of his house. Jason sympathizes with her plight, and lets her sleep with him, innocently, that night, with Coco promising to leave before anyone wakes up. He surreptitiously watches the petite teen undress and put on one of his tee-shirts to sleep in, and she lies on the bed with her back to him. He advises her to find her own friends, and stop hanging out with the wrong guys. "I know, I actually found a guy who's really sweet, but it's pointless. He'll never like me", she tells him. "You'll never know unless you try", Jason responds. Coco impulsively kisses Jason, and he backs away from her in surprise. "If I'm not pretty or something. I knew you thought I wasn't pretty!", she exclaims. "No, you're beautiful. We can't", Jason responds. "Do you have a thing for Theodora, or something?", she wonders. "No, ol course not", he says. "Then what is it? We don't have to tell people that I'm your stepsister. We'll just say we're really close", she insists. He lets her stay, but they get under the covers back to back -no sex. Later, Coco reaches over and starts fondling Jason's groin, pleading: "I want my first to be with somebody who loves me". "I should not be your first -I can't be", Jason replies. "I think you want to be", she starts giggling and pulls off his pants. "I've never put a penis in my mouth before", she murmurs. Watch the taboo scene unfold, and then see Theodora in action in Part 2.
