An Unexpected Grooming Experience with a Friend

It started out all innocent. My buddy, ****, wanted to help me "manscape". He was a jock, athlete, had a reason to keep his body smooth. I didn't have much definition at all. I'm only 5'7" about 135 lbs, compared to his 6'1" and pecs and abs... Pretty much every muscle the body has, could be seen on him.
"Fine," I consented. We went into the bathroom and he pulled out a trimmer. The chest was easy, I was already smooth there, but before the waist was intimidating. I wasn't well endowed. I closed my eyes and followed his instructions... When we were done, I couldn't get over how smooth my legs were. "Wow! Just like a woman's!" ***** ran his hand up my leg, and as he did so my nerves exploded! I was so turned on I got an erection, however small it was, he noticed.
"You like that?" He asked.
"Weirdly, yes." I offered. "That turned me on." The words just fell out of my mouth without thought.
"Well, let's see what else turns you on, shall we?"
***** dropped his shorts, his body smooth, ripped, and very well endowed. My mouth fell open at the sight.
"Haha! Nice!" He chuckled. The problem is, I'm straight. So, if you wanna get with this, you gotta dress like a girl, but that's okay, you've got the legs for it. *****'s hand felt it's way up my thigh and my heart was pounding!
"Uh, I uh, ummm, I uh..." I couldn't speak.
"I've got an idea. My roommate's out of town tonight and tomorrow, she may have something in her closet," **** informed me.
"How do i, what do we, do?" I asked.
"Let's just see what happens."
I crept over to *****s roommate's room. She wasn't home, but I felt the need to be stealthy. She had a chest of drawers, inside I found a pair of lacey black panties, some thigh high stockings and a bra. I went to her closet, on the right side was a few pieces of lingerie pushed back in the corner. There it was, a pink corset with black trim. I didn't know if I was her size, but I had to try. I put on the bra and panties, pulled the stockings up, then fiddled with the corset. Front closure with ties in back. I got it on and closed, but not tied. I went back in to *****'s room. He was on the bed now.
"Wow! You look the part!" He exclaimed. I felt flattered. Perhaps this was my calling. I confessed that I couldn't get the corset tied. He offered to help. He stood behind me, played with the strings then pulled. I felt the corset cinch around me, squeezing me. "Tighter please," I asked. He started at the top, then the bottom, then back to the top, then to the bottom, withing his way to the ties in the middle. When he got there he pulled and the corset tightened strongly.
"Ooof!" I exclaimed as the air was pushed out of me. Then as my body adjusted I realized, this was perfect. It held me, and my body felt it all over.
"Too tight?"
"No, no. It's perfect. I love it!"
"I love it too." **** countered.
He turned me around, looked me head to toe, then he kissed me. I kissed him back. Then I kissed his chest. Then I kissed his abs. Then I kissed the top of his penis. Then I opened my mouth.
The taste was immense. I had to get down on my knees because the corset was forcing me to have good posture. I felt him becoming more and more erect as I sucked. I gagged some, but tried to hold it off. This was the best thing ever.
After what seemed like a few moments, **** grabbed my arms and pulled me up, then threw me on to the bed, on my stomach. I pulled my knees up under me, and he pulled my panties down.
A mouthful of spit came from ***** right down between my cheeks. His erection followed. As he slid into me, I knew my life was changed forever.
I've got a few corsets of my own now, a
