Fuck her ass

You stand, quickly undressing and pulling out your hard cock. You help position Caoimhe, bending her over the bed as she obediently grabs her ass cheeks, spreading her cheeks to allow your thick, bulbous cock-head to be lined up with it, ready to penetrate. Caoimhe nods so you're sure she's ready, and you slide forward. Awkwardly, your cock slides, missing the first few chances to slide inside, as the first few thrusts to enter her just leave your cock sliding along her asshole. Then, you grip her tightly, and press your cock against her anus, before slowly moving forward, holding your cock in place.

Your head disappears inside of her with surprising

"Wait!" Caoimhe begs, taking deep breaths to calm herself. "Give me a moment... to get used to it."

You hold for a moment, feeling the tight squeezing on your cock, the strange sensation of warmth and tightness without the familiar wetness you normally find in the holes you frequent. After a few seconds of holding your position, Caoimhe looks at you.

"OK. Slowly, please."

You slide in forward as Caoimhe whimpers, her anal virginity being taken. Her tight ass squeezes so tightly around your cock, the strange warmth taking you as you have to focus to not just start hammering away. Slowly, your cock disappears into her tight confine, until Caoimhe's surprisingly taking your entire length, with little more struggle that an at first getting your cock in.

"How does that feel?"

"Its OK. Are you in fully?"

"I am."

"OK. You can... you can fuck now."

You slowly slide backwards, allowing your cock head to rub along her insides, filling you with pleasure. You grip Caoimhe's hips tightly, slowly sliding out until only your cock head remains inside, before your cock disappears inside of her again. You slowly find a rhythm, slipping in and out of here as you feel every bit of pleasure of her tightness. Caoimhe moans, half in pain, half in pleasure, but she remains eager to take every bit of her tight pleasure cave. You start thrusting, soon taking up a rhythm as you fuck her sexy ass, using the last unused hole of your girlfriend, making her completely yours. Her ass feels so tight as you continue fucking, almost struggling to keep it from squeezing out your hard dick. Your cock is squeezed so tightly, squeezing your dick closer and closer to orgasm until you're eager to blow your load.

"Can I cum in your ass?"

"Whatever you want. Fill me up, baby."

You keep thrusting, until finally, your cock fires, cum spurting out as you thrusting slows, sending spurts and spurts of cum deeper into her asshole, filling her ass with your cream. Caoimhe moans in pleasure, gasping as her little asshole is filled with your cum. Slowly, yo slow down, until your softening cock is pushed out of her asshole by her squeezing. You groan in pleasure, leaning in and wrapping your arms around her in a hug.

"God, your asshole felt good," you say.

"I'm glad," Caoimhe acknowledges. "It was nice to try."

"Maybe we try again some time."

"If you want, though. Not now, though. I need a break."
