Yes/Chad/Cum in her cunt and change position
You shoot a massive load of incestuous cum deep inside your sister as she quivers in orgasm. You lift her up and turn her around, not letting her come completely down from her orgasm, and not taking your cock out of her cunt. You let her down until her feet touch the ground, then put her arms against the column she was just pressed up against. She grabs hold obediently, and looks over her shoulder at you as you start to fuck her slowly in the standing doggy position. She whimpers softly as you fuck her, gradually increasing speed.
"Oh god," she moans, "fuck me."
"Who am I?" you ask her. Hoping to get a little more out of her.
"Chad," she says, "yes, fuck me Chad."
"Just-" you start to say stopping yourself because of the ring. Rephrasing, you ask, "What am I to you?"
"Okay, big brother," she says, "I get it. Fuck your little sister!"
"Try again," you say as you pound her.
"God," she moans, "what do you want? You're - fuck - you're my brother - yeah, like that - my lover - fuck - my husband - ugh! - my master, my owner, my GOD! Please give me your cum." Seeing that as the perfect response, you pump yet another load of cum into your sister, then sink to the ground with her. You hold her as you both come down from the intense experience.
"My god," she says, "I can barely feel my legs."
"Um hum," you say with a chuckle. "I'm your god."
She elbows you lightly. "My poser god." She gets quiet for a bit as you hold her close. You just enjoy her presence for a time, then she says, "No, actually!" Then she sits upright.
"What?" you ask.
"You aren't my poser god." She gets up, and starts getting dressed. "I meant what I said. You are my god now. I am your servant. I am your property. I am your slave. I'll be anything you want me to be. What I want you to be is my master, my owner, my god-king . . . and I want to be your queen." Finished dressing, she grabs her skateboard. "But there's something we need to take care of first!" She jumps on her skateboard , and jets away at a decent speed with practiced agility. You know you can easily overtake her, but your curiosity gets the better of you. You follow her at a discrete distance.
She skates back to the school, and right into the halls. Skating through the hallway, she shoves the hall monitor on his ass as he tries to stop her. She rolls through the hallways at break-neck speed, and only stops briefly to pick up her skateboard before barging into a classroom you know all too well . . . Ms. Wells trig class. You follow your driven sister into the classroom, becoming a bit concerned over her possible intent.
She wastes no time, jumping over a desk, and laying her board heavily into the side of Dana's face. The pretty black girl is caught totally by surprise as she is violently ejected from her desk. Gwen tosses the broken skateboard to the side, and is on Dana like a tiger on a wounded faun. She lifts Dana off the floor , and knees her twice in the abdomen in rapid succession. Dana seems completely dazed and unable to respond to the sudden attack. The look in Gwen's eyes tells you that this is only the beginning.
How do you handle this turn of events?
