violated at the dentist's office

just a hastily written story for this pic. this is basically the first thing i have written

how do i put the spoiler button in the post?

I started groggily waking up. I could remember going to dentist's office for a routine checkup but now I was lying stomach down on the patient's chair still half asleep. As I started to become aware I felt something in my rear area, it felt like my butt was open! When I tried to clench my muscles I instantly became alert as I felt a hindrance in my rectum. There was something long and hard steadily pumping in and out of my ass! I tried to get up but someone much stronger than I am was holding me down, so I looked behind me to find that pretty nurse I had seen earlier thrusting into me, her hips smacking into my buttocks gently. She looked at me, apparently just noticing that I'd woken up. Her top was unbuttoned and her breasts were jiggling with every movement. She had an excited look on her face yet she kept glancing at the door.

"The doctor should be here any minute, but I just couldn’t help myself!" she bit her lip and looked down, apparently admiring the sight of her long schlong violating my asshole. That was when I finally registered the new sensations being forced upon me. My ass burned, even though she was being relatively gentle, and at that moment I felt a sense of humiliation I had never felt before, yet inexplicably, my dick started to get hard very fast. "Oh, I knew you'd like taking it in the ass. I could smell the bitch in you as soon as you walked through the door," she taunted as she started to speed up her pace. I started feeling worse because despite the pain, it was starting do feel good. My swaying dick was as hard as it had ever been as her shaft kept stroking a certain spot in my butt. I could feel the cum rising from my balls, I was gonna cum without even touching my dick!

I couldn't let that happen. She had already mocked me for getting an erection while getting ass-rammed and that was bad enough. If she saw me come I felt I might die of embarrassment.

In the end though, it was no use. It was as if she was repeatedly pushing an 'ejaculate' button buried deep in my ass. I held it in for as long as I could, which made it even more intense when she forced me to shoot out the most powerful orgasm I had ever had. I couldn’t help but cry out pathetically as I spewed ropes of semen onto the chair beneath me.

"Oh my god, are you coming!?" she asked with ecstasy in her voice. "Your butt is closing around my cock. It feels amazing!" A few seconds later she unloaded a copious amount of steaming hot jizz into my bowels. It felt like it went on forever as I could feel it every time she spurted forcefully deep inside my butt. When she was finally done she gave me a loud smack on my butt cheek before sliding out her dick. My anus felt ruined, and I could feel her little gift sloshing around in my guts, still steaming hot.

I didn’t get to have my check up
