Have Beth use the strap-on

"I'm not insecure to be compared to a piece of plastic," you chuckle. "Go on, get it out. I could use the help."

Beth nods, as you wrap your arm around Caoimhe's waist, enjoying the warm feeling of her skin on yours. Beth ventures over to the drawers, pulling out a curvy, purple dildo attached to a black harness. Katie smiles eagerly, leaving your cock go as she sticks up her little ass in the air, wiggling it in front of Beth. You watch as Beth guides the plastic cock to her pussy, pressing it against Katie's slit. Katie bucks her hips, eager to take the full length as Beth thrusts forward, the dildo disappearing inside Katie.

"Oh, I can feel your tight little pussy tighten around my new cock," Beth smiles, as she continues her speed, leaving Katie moaning loudly with each thrust.

You pull Caoimhe close, bending her over the bed, positioning her so that her face is almost touching Katie's. Katie eagerly latches onto Caoimhe's face in a series of sloppy kisses, the dildo still buried in her pussy. You take your cock out, pressing it Caoimhe's wet slit. You gently rub your cock head all around her slit, letting her pussy juices coat it, before you thrust forward, penetrating Caoimhe.

"Oh fuck," Caoimhe splutters out between kisses, as you're fully buried in Caoimhe's cunt.

Katie and Caoimhe continue to make out, their tongues exploring each other's mouths, as Beth and you grab onto Caoimhe and Katie's hips, holding them tight as you both take up a pattern. Soon, you're thrusting in unison, eliciting a matching chorus of moans from the two little sluts as you fuck them, harder and harder.

"Oh, yeah, baby," you moan, your cock bursting deep into Caoimhe as you increase your speed, cock head rubbing and pressing against her inner walls.

Katie begins to thrust her butt back, trying to get the strap-on deeper and deeper inside of her pussy as she's filled with pleasure. Beth's inner thighs are coated with her leaking pussy juice, her eyes trained on the tight little fuck toy she's balls deep in... figuratively.

"Oh, that's right! Take it like a little slut for me, Katie! God, this is so fucking hot. No wonder you like it, Jack! I feel powerful!"

"Oh, I'm getting really close," Katie says. "Oh, Beth, fuck me harder! Harder!"

Caoimhe and Katie burst into excited moans, the two of them starting to cum as you. Your balls slap against Caoimhe's clit as you penetrate her. Caoimhe squeezes down on your cock, giving each of your thrusts some resistance, but the pleasured gasps elicited from Caoimhe with every thrust just turns you on more, giving you the energy to fuck her harder and faster, eliciting even more moans of pleasure.

"Alright, now I want to fuck Caoimhe!" Beth suggests. "Shall we swap?"
