Won't say how old I was when this happened but a church preacher used to use me for anal sex

It started one afternoon after a church event. He took me into his office. He was giving me a talk a d the whole time rubbing his hard on through his pants. Finally he stood up, dropped his pants and he was standing there it's a hard in in his white briefs. He was in his 50s.

Then he had me stand up, he undid my pants a d let them fall to the floor. He proceeded to pull my white briefs down and had me lean in his desk. I guess I sorta knew where it was going. He reached in his drawer and pulled out some Vaseline. He rubbed Vaseline on my butthole then at a steady speed he pushed his dick into me

The pain was intense but he kept saying relax. After a few minutes of him just leaving his dick in me, he vent me over his desk and said your ready. That's when he started thrusting in and out. At that point I was sorta used to it but it still hurt. After about 5 to 10 minutes he tensed up and I felt him cumming in me.

After cumming he pulled out, grabbed tissues and wiped my butt off. He told me to pull my underwear and pants back up. My butt was so sore. I swear I was walking funny. He told me while he was getting dressed that he did cum in my butt and in a little but I probably will feel the urge to go to the bathroom. He said at that point I just ha e to push the cum out.

These little sessions went on for a few months then he just stopped. I'm not gay by no means but I got used to taking him anally
