Make Her Swallow, and Tease Her

(This chapter inspired by Thunder30.)

Your sister's insatiable mouth is sucking your cock like her life depends on it. You're not lasting too much longer. As you take a big bite of your breakfast to hold back your groan, you shoot your first load of the day right into her mouth, coating her tongue and throat.

Kelly doesn't miss a beat. Feeling your cock's impending explosion, she made a perfect seal with her lips right at the tip of your dick. She swallows every single drop of cum you give her. She then gives out a satisfied sigh.

"God, that tasted so damn good," Kelly says under her breath. She licks up a few stray strands left on your dick. You shiver and discretely slip the MCR off of your cock and into your lap.

You glance at your sister and see her nipples sticking strait out, harder than you've ever seen nipples get. You can tell your sister is completely horny.

"Barbie," you say around a mouth full of toast, "stick your hand down your pants. Have Kelly masturbate."

Kelly immediately brings her hand to her crotch, sticking it right in and playing with her pussy.

Kelly moans, "Fuck, I'm so damn horny I could fuck myself at this table right now."

Obviously, your order that was specific to Barbie didn't quite make it to Kelly's consciousness.

"Barbie, have Kelly look down and notice that both her shirt is gone and that she's fingering herself. However, do not stop fucking that twat. And whatever you do. Do. Not. Cum."

Kelly then looks down and gasps. "What the fuck? Where's my fucking shirt?" She gasps and moans. "Oh god, I'm fucking myself... Mmm, god. it feels to good to stop..."

Her eyes close in bliss, and you continue to watch her. You're already getting another hard on just watching your sexy sister fuck herself without a care.

After a moment, her fingers stop and she gasps and frowns. "Huh?" she says to herself. "Why'd I stop? I was so close..." After her breathing normalizes and she calms down, her fingers start moving again, fingering her cunt with wild abandon. "Oh my fucking God" she says with a moan before suddenly stopping once more. She groans in frustration. "What the everloving hell? Why won't I let myself cum?"

As you grin to yourself and finish up your toast and cereal, you watch Kelly continuously fuck herself and stop, frustrating herself and unable to reach her orgasm.

Your attention turns to your mom, who's flipping through her phone while she eats.

What shall you do with your currently oblivious mother?
