... in her tight little asshole.

You had tested it. Lubricated it. Only barely threatened to part its tight, unviolated pucker. You don't know the state of her colon... and you don't care. Your cockhead, swelling as the pressure builds at the base of your spine, offers no mercy as it pries her asshole open, centimeter by centimeter, the ungodly pressure causing your whole body to shudder violently as you defile her virgin anus. You're not about to knock up the girl ready to go back to her family... but there's just no way of convincing yourself to not come inside this helpless, cock-shy slut. Despite your mercy, her face shows nothing but wide-eyed disbelief, a whimper that doesn't match her gaping, frozen mouth, and the breathless horror as she feels you **** past her inner-sphincter and slam your entire rod into her rectum. Your body arcs as the intense pleasure shoots up your backbone and out of your manhood, blinding you with stars and the colors of satisfying, defiling release. She offers no words, no pleas as you grind and shake your pelvis, rubbing the invading head all over her terminal intestinal walls as you paint her insides, enjoying her immobile state as your personal masturbation toy. You finally fucked Penelope... and there wasn't a damn thing her family could or would do to fix it.

"Oh God, Penelope... you should thank me, since I just saved your life," you manage in a shaking voice. You give her a few more pumps; your dick still isn't soft, and you think you're ready for a proper round of anal now. She doesn't reply. You withdraw your meat until your head threatens to be squeezed out - God, the pleasure, how is she not a professional with how she's-! - and then bury yourself back into her ass. "Thank me, slut."

With no tears left to cry, she smiles as she sobs out her words.
