A blowjob.

Tibby giggles quietly, her eyes on the bulge in your pants. "You think she'd be jealous if I played with that?"

"Only one way to find out," you whisper back, already lifting your butt so you can pull your sweatpants off. The moment your cock is out, Tibby reaches down to wrap her hand around it. Glancing over at the kitchen, where Ashley is just opening a cupboard to look for snacks, Tibby gives you a few slow strokes.

Then she bends over to lick along your shaft. Once up and down the side. Then along its bottom, her head in your lap and her face up to make eye contact. Finally she sits up a little to lick and kiss its tip. Your hands land on Tibby's head, encouraging her to take your dick into her mouth. That's when Ashley comes out of the kitchen, her arms laden with snacks.

"Well well," she smirks as she places the snacks on the table. "I guess I'm not the only one being affected by this punishment."

"Edging you on my lap was a mistake," you admit, groaning when Tibby's lips plunge down your shaft. "I needed some relief after you rubbed your booty all over me."

"If I help her give it to you, is there any chance I can get some relief too?" she asks.

You know you should stand firm, but you're too far gone for that. All you can do is nod, and before you know it a naked Ashley is kneeling in front of the couch, leaning forward to lick the lower half of your cock while Tibby bobs on the upper. While she licks away, Ashley snakes a hand down between her legs and starts rubbing her clit. Her other hand goes to your balls, fondling them as her tongue flicks against the base of your cock.

After a while of blowing you Tibby lifts her head to let Ashley take over. Standing up, she watches Ashley wrap her lips around your mushroom head and suck it into her mouth. Then Tibby takes her clothes off, one garment at a time until she too is completely naked. "This time I'm stealing him!" she declares as she pulls on Ashley's shoulders until your dick pops out of her mouth.

All Ashley can do is say "oh" and sit on her butt, watching the thieving cat straddle you and line up your penis with her entrance. Tibby lowers herself slowly, sliding down your shaft until it's fully sheathed in her pussy. That's when you hear Ashley's plaintive voice from behind her. "Do I still get to cum?"

You have to laugh despite the situation you're in. "Go ahead Ash. We weren't serious about making you do this for hours, you know."

Ashley begins to mutter something under her breath, but cuts herself off with a moan when she starts fingering herself. You can't see what she's doing, but it sounds like she's having a good time down there.

Meanwhile Tibby begins to ride your cock, staring at you with lust in her eyes as she raises her hips and drops them back into your lap. You kiss her, then grab her butt and start lifting her in time with her own movements to make her really bounce on your dick. Tibby mews loudly as your cock rubs against her inner walls, and the sound is accompanied by moaning from you and Ashley.

You bottom out with every thrust, digging your fingers into Tibby's booty and giving it an occasional smack, making the kitty squeal and clamp down around your shaft. You fuck her rapidly, and when she arcs her back to shake her tits you pull her down against you, burying your face between them as you cum, filling her pussy with your seed.

You can hear Tibby's voice above your head, letting you know that she's cumming too. After a while she settles down, resting her head on your shoulder while your hands come up to stroke her back. Looking down past her sweaty body, you can see that Ashley is right on the edge as well.
