I placed the head of my cock at her anus, and started pressing it forward. I felt her sphincter instinctively tighten, fighting to keep out this unfamiliar intrusion. The trick in such a situation is not to increase the pressure - that will either result in the cock sliding off the target, or pain/injury to one or both parties. So I kept the pressure steady, and focused on keeping my cock right at her anus. The sphincter muscle can't sustain a tight contraction for long, and soon I could feel her resistance weakening. The sphincter slowly gave way in small steps, and at each weakening, my cock slid forward a few millimeters, aided by the lubricant and the steady pressure.

Then, as I was expecting, the sphincter suddenly gave way, and the head of my cock slid in easily, while she uttered a gasp of surprise. I held my cock in that position until she got used to my presence. Although this was rape play and I could be as rough as I wanted, I didn't want to ruin her first experience with anal and put her off that for life.

After I held my cock in position, only applying pressure at times when her sphincter tried to expel me, I could feel that the attempts to push me out were becoming less frequent. So I slowly slid my entire length inside her not-virgin-anymore anus while she drew a sharp breath between her clenched teeth.

She sighed as I slowly withdrew, until the head of my cock was all that was remaining inside her. I pushed in again, and the sharp in-drawn breaths and the relieved sighs sounded in tact with my rhythm.

After a few thrusts, I could feel her anus loosening up and becoming nice and slippery, and her breaths and sighs started turning in to soft moans. I ordered her to slide her palm underneath her and start massaging her clit. Soon, the room was filled with the sound of my rape victim's first ever anal orgasm.
