On my knees

I couldn't believe I was doing it, but my body felt like it was on autopilot. I got to my knees and turned my back to him, presentinh him with a view of my ass.

"Oh, the birthday boy wants to pop his cherry," David said. "I'm normally a bottom, but for your birthday I can make an exception."

I don't know what had come over me, but he didn't really give me much time to think about it. I felt him lean down and run his tongue up the crack of my ass, and then he was in position, the head of his cock against my asshole.

"Happy...birthday," he said as he applied pressure.

I was surprised at how easily my asshole stretched to allow David's cock inside me. For the first few seconds there was an intense pain that made me think I'd made a big mistake, but once he was all the way in, it subsided. It was replaced by a sensation of pleasure like nothing I'd ever felt.

"Like that don't ya?" he asked as he slowly fucked me in the ass, and much to my surprise I really did.

I felt no attraction towards David or his cock at all, but the sensation was beyond words. I couldn't help but moan softly as he fucked me.

"I'm almost there," he told me.

"Hey, Alan!" a voice said from acroas the room.

If I could have dove from the bed and covered myself I would have, but David kept me pinned to the bed by fucking me harder. I turned my head towards the voice only to find Amy standing next to the open closet door, filming me with her phone.

"Oh fuck, Alan," David moaned as his balls exploded inside me.

"Oh God yes," I moaned as a second later I orgasmed myself without even touching my cock, spraying cum all over the sheets. Apparently he had managed to trigger my prostate.

"That was great," Amy said as she shut off her camera and pocketed her phone. "Thanks David."

"Trust me, it was all my pleasure," he said as his limp cock slipped out of my ass. "Happy birthday, sexy. Call me."

David quickly pulled on his clothes and left. Amy stood over me smiling.

"That went better than I thought it would," she said with a laugh.

"You can't tell anybody," I begged.

"I don't have to tell them, I can show them," she said, patting her pocket. "From blowjob to ass fucking, its all right her on video."

"Oh fuck," I moaned. Now my ass was starting to hurt.

"I really expected you to storm out after the blowjob," Amy said. "I did not think you'd get on your knees and give it up o easy."

"Why did you do this?"

"Because now I own you," she said.

"Please, delete it."

"Nah, its too good a leverage," she said. "I might need it someday. Not right now though. Right now I'd suggest you get your shorts on and get in the pool. Your asshole ia gonna be a little sore for a while. It'll be easier next time."

"Fuck no! There won't be a next time."

"We'll see," she said and left.

Slowly and carefully I pulled my swimming trunks on.
