Damage Control: Obedience Training

You step out of your pants and kick them up to you so you don't slide out of Kelly. You grab the ring and pop your finger out of the bed in front of her and she eagerly takes it into her mouth as you consider what to do next. You needed a way to suppress or otherwise control Kelly's anal compulsion, depending on how much of a dick you wanted to be there were a few ways you could do it.

Kelly's moans around your finger and her gyrating hips on your hardening cock make up your mind: "Dick it is." "Mnn?" You squeeze the ring and clear your throat, "Kelly, when you taste or otherwise sense my cum inside you you feel compelled to do what I tell you to do... unless it's impossible or would seriously damage you. You love the taste and the feel of my cum on or inside you but you can still be resentful about my power over you and your dependence on my cock. You will rationalize all of this as part of your weird compulsion and not suspect that I gave it to you." The ring vibrates and Kelly's lips make a popping noise as your finger slips free.

"Why do you keep talking like that?" You hesitate, "And why are you always sooo right, oh fuck it feels good to have your cum in my ass!" Nice.

"So Kelly... I gave you your compulsion to have me fuck your ass."

"Pft, yeah right."

"Bitchin'. Alright Kelly, I think we're done for now." You pull out of her with a shared groan, "How's that lube feeling?"

"It's warmed up and it kind of tingles... and it's still slippery so why don't you get back in there!"

"Eh... I don't think so. You've had enough."

"Please?! I'll do your chores for the next week!"

"Nope."

"I'll wake you up with a blowjob every day for a week!"

"You're speakin' my language now but still, no."

"Come on John!"

"Call me something more respectful than my name when we're alone or with Mom."

"Yes... Sir... but I will literally do anything if you-"

"That's enough Kelly."

Your sister slumped, unable to continue begging thanks to your command. She slowly got up and looked at you sadly, puppydog eyes in full effect.

"Oh my God would you just take no for an answer?"

"I didn't say anything!"

"You didn't have to, jeez. Feel like I kicked a puppy. Ok Kelly, I'll tell you what." She perked up, looking hopeful, "Since you've been so good and since I still have a messy cock, I'll let you blow me right now." She glanced down at your shiny cock with a look of disgust but began to kneel, "Only if you want to, of course."

She stopped. You waited. She licked her lips and looked up at you resentfully, "It's not even that bad, not like I didn't clean myself before coming to you... Sir."

"Are you telling me or justifying it to yourself? Also: no hands."

She glared but didn't break eye contact as she bent forward and nuzzled your erection, bobbing it this way and that over her features. It seemed like more than what you asked for until you realized she was covering her face in the traces of cum her ass hadn't sucked off.

"Does that feel good Kelly?"

"No! ...sir."

"Tell me the truth sis..."

"...yes." You give her a hard look, pulling your cock out of reach until she rolls her eyes, "Yes sir, it feels good." You smile and let her at it.

She bobbed her whole torso back and forth, hands clasped behind her back, tongue slipping out to maneuver your bouncing cock over every inch of her face. She shivered and slipped her mouth over the head, letting it spring free and strike her nose. You turn back and forth, lightly cock slapping her cheeks as her eyes became more heavily lidded and her breathing quickened. She licked and sucked the tip of your cock, drawing out small dribbles of pre that she deftly spread over her face.

It was one of the hottest things you'd ever seen, made better by the fact that this wasn't porn: just your sister doing it because she wanted to. But you had limits to your patience. As she lapped up your cock into her mouth a final time, you grip her by the back of her teasing head and **** her to take more of you. You begin thrusting, sliding deeper until you are hitting the back of her throat. She makes an indignant noise and her hands unclasp-"Keep 'em back there"-before sullenly rejoining as she stared daggers up at you.

You pick up the pace, your thrusts hitting the back of her throat harder and making **** noises, "You can try and relax your throat and swallow with the thrusts." It wasn't an order, so it took her a while to get the hang of it, but holy shit it was worth it. "Ohhh Fuck Kels... Your throat is sooo good!" She tries to say something and the vibrations egg you on, now edging into deepthroating territory as your pullback becomes less and less. Her eyes are tearing and she looks at her limit but you're so close... you just have to decide where she gets her reward.
