It came down to the little moments. That feeling of intense pressure and stretching open as his c*** entered my virgin bottom, my mind panicking and that inner voice screaming “omg he is trying to put his c*** in your a** you can’t let him do this to you”. That panic disappearing with the sudden relief from the pressure as my body yielded to accept him and the breathlessness of him effortlessly sliding in fully. I had been physically squirming to escape it but as soon as my body yielded and he was sliding in fully my body went limp as I was completely unmanned in an instant,groaning with the fullness of it. I squirmed under him because I felt impossibly stuffed and impaled. He lay fully on my back, gently whispering in my ear and blowing on the back of my neck and despite the overwhelming sense of impalement i could feel his c*** twitching inside me. Breathe, he told me, kissing the back of my neck and shoulders. He asked if i was ready, i whimpered. He slowly pulled back for a first thrust and i moaned from that helpless sensation. He was nearly out of me and i panicked again. Shocked at how my body clenched and tried to hold him inside me and my hips pushed up and back to keep him in me. I heard him chuckle and then he slowly plunged back in fully and i groaned in pleasure. Aware of nerves deep inside my body that had been dormant until his c*** woke them. He began to slowly deeply f*** me and i became a helpless w****. Growling moaning wailing as his c*** slowly relentlessly plunged into my guts over and over. He never quickened his pace, but sometimes stayed deep and ground his hips against my cheeks and told me how my insides were spasming around him. I have np idea how long it went on I only vaguely recall my eyes rolling back in my head constantly. At some point he pulled my a** up and it was so lewdly vulnerable. A rare moment or twelve of “omg you are letting a man f*** you in the a** wtf is wrong with you”, but my body knew what it wanted. At some point I was turned on my back and my legs instinctively went up and around his waist and my arms around his neck and shoulders and i was lost. He thrust deeply, growled in my ear, and my clarity was absolute….a man was about to empty his sperm inside my a**. I blurted it out….yes baby…and i felt it happen as his c*** literally swelled and twitched inside me. He collapsed on me and i clung to him desperately. It was final…..i had long known I was a cocksucker but now I was not only a f*****, i was his f*****.
