Offer her your ass

You move to the ground, bending over and offering up your panty-clad ass. Saoirse wastes no time, tearing the panties clean off you in a single, solid motion and tossing them aside. Then, Saoirse presses the strap-on against your anus, pressing forward as you let out a little moan.

"Ready, slut?"

"Use me whenever you feel the urge to, mistress," you say meekly.

Saoirse smiles, thrusting forward as she penetrates your asshole. It stretches around her strap-on, burning from the lack of lube, but Saoirse doesn't seem to care. She knows the truth, that you don't care either. Because you're just a little fuck slut, who wants to be used as quickly, as often and as hard as possible, without regard for how much it hurts. Saoirse grabs you by either the side of your waist, pulling you onto her cock with every thrust as she jams into her. Your g-spot sends trembles of pleasure running through you, your cock hardening. Saoirse slaps her ass hard, causing you to moan, as she continues to pound you as hard as she could.

"Take my big dick, you little whore. Let daddy show you how good it feels to be a little slut!"

"Thank you, daddy!" you moan in response, before Saoirse laughs.

"God, you're so pathetic," she says, giving your ass another smack. "You're a filthy little hole that just needs to be filled! My own personal cum dumpster!"

There's a loud slap with every thrust, your asshole getting stretched wider and wider. The strap-on is clearly rubbing against Saoirse's clit, no doubt as she intended, while she moans extensively, while filled with pleasure. As she forces you down again, you note that her inner thighs are covered with pussy juices. Saoirse moans gently.

"God, that feels so good."

Finally, the urge to cum begins to overwhelm you, as you grow even more and more eager to explode all over yourself, your balls filled. You groan in pleasure, your asshole tightening around her asshole, squeezing it as you ready yourself to cum.
