Have a peek

Tai knows it's wrong, but he can't help himself. So he quietly cracks the door, and sees on his bed. Kari sitting their only wearing a bra on one breast. One hand fingering her vagina, while the other carreses her revealed breast. At first Tai is upset that she's masterbating on his bed, and not hers. Then his penis hardens as he watches his sister. Tai decides to continue watching, as he whips his penis from his shorts, and rubs the shaft. Kari's fingers move in differ motions inside her vagina massaging her clitoris. Tai goes to get on his knees, but stumbles into the room. "AAAAHHHHHHH!" Screams Kari covering herself as quickly as she can.

"Tai....hum......you okay? Kari asks. Tai still face down on the foot sits up, his penis still hanging out "yeah" he says. Kari notices"YOU PERVERT, YOU WAS WATCHING WASN'T YOU!" screams Kari angerly while blushing in embarrassment.

"Here's....busted" reply's Tai. Before either could say another word, they her a scream from their parents room. Tai re inserts his penis, as Kari wraps up in a robe. They then rush down the hall to their parents room, opening the door. Only to see their mother laying naked on the bed, and their farther standing beside the bed, also naked. Blood on his mouth, with fangs inside. His eyes black with glowing red irises, staring at them. "Good now I don't have to come looking for you" Susumu says with a smirk.
