Compromising with Kelly

Because of all the activity today, despite still being in your sister's tight asshole, your cock starts to go soft.

Feeling this, Kelly frowns deeply. "Why are you going soft on me? Don't you like fucking my ass?" she asks with a pout.

You shudder and look at her. "Kelly, your ass is the most amazing, most fuckable ass in existence. It's not you. It's me. My dick is going raw and it's actually starting to hurt." You gently pull away from her and your soft dick slips out of her well-lubricated ass.

Kelly immediately starts moving, trying to get her head close to your cock. "Do you want me to make it better? I'll lick it, make it feel good again."

You stop her, placing a palm on her head. "Kelly. Get a hold of yourself. I really, truly need a break. I cannot fuck anymore today."

She frowns. "But you've been here all day. You haven't been fucking at all."

You think quickly. "I've basically been jacking off non-stop all day."

Kelly pouts again, crossing her arms. "Selfish John, using all of his hot hardness on his hand."

You find your sister's obsession with your dick in her ass really hot. Still, you need to focus.

"Okay," you say. "Let's compromise. Tomorrow, if you do a couple of my chores for me, I'll fuck your ass again."

She looks up at you hopefully. "You mean it? All I have to do is some extra chores and you'll give me what I want?"

You nod. "Cross my heart."

She eyes you suspiciously. "You're not going to jack off for most of the day again, are you? I want the next time to last way longer."

You chuckle. "I promise I won't even touch my dick, unless I shower or piss."

She nods. "Good. And if you DO feel horny, we can always just do it multiple times tomorrow. Or even one continuous, all-day session. I'd totally fucking love that." Kelly gets up and stretches, showing her amazing body to you. You almost drool at the sight. She sighs, dejected. "It's so weird. My ass feels super empty without your hard dick inside of it." She glances at your cock and licks her lips. "Are you sure---"

"Out," you say as you pick up your underwear. "Before I change my mind."

She pouts and leaves.

You pick up the MCR. Obviously it's powers need to be focused a little better. Your thoughts turn to Kelly. Should you fix her compulsion? Maybe make her forget the whole thing. Or do you like her this way? Maybe you should even make her completely obsessed with all different kinds of sex with you. Decisions, decisions...
