I was naked on all fours on my bed. Mark came out of the bathroom with a bottle of lube in one hand and his erect cock in the other. He walked up to me and sat on the edge of the bed. His hands were shaking so he put the bottle down.
"Don't you want to fuck my asshole?" I asked.
"I've never done this before, Tom"
"Stand up," I said.
I stood up when he did. I grabbed his cock. He was oozing precum like a leaky faucet. "You're gonna squirt that shit on your cock head and my asshole. But first I want you to tongue fuck me," I told him. I crawled back
on the bed and lay flat, face down, spread my legs for him.
"Get up here and spread my cheeks."
He crawled up behind me and soon I felt him massaging my ass. His hot breath on my wet asshole was making me hard as hell. He was very good with his tongue.
"That's nice. You're doin' great. Now, stick it in my hole. Pull those cheeks apart and tongue rape my asshole!"
Mark spread me open and shoved his tongue up my ass as far as he could. It felt great.
"In and out, Mark. Fuck me with that wet, warm tongue!"
He suddenly pulled out and slapped my ass HARD! Then again and a couple more hard whacks had my ass stinging, my cock was even harder now. Then I felt his tongue up in my tight little asshole again.
"That was great. I'm so fucking hot right now." I stood up and slapped him hard in the face. He looked at me and said nothing, so I hit him again. I grabbed his hardon and got in his face. "Fuck my asshole, Mark."
I got back up on all fours on the bed. I stuck my ass out as far as I could. I felt the cold wetness of the lubricant being spread over my anus and then a finger went up inside me, again moving in and out like I had a rectal itch that he knew how to scratch. Then two fingers. That was a tight squeeze but it felt so good that I began rocking my hips to match his finger thrusts.
