This happened to me last semester in school with a guy that lived on my floor. I met him on tinder and mentioned I was interested in bondage. He was really excited to help me have my first time. An hour later he was at my door I let him in and we made small talk for a minute. Then he bluntly asked if I was ready.
We both sat down on my bed and he told me I should take off my shirt. I complied and he pulled a short piece of rope from his bag. He motioned for me to put my hands behind my back. Once I did he expertly tied them together. He placed a hand on my shoulder and asked how I was feeling. I replied “a little nervous but I found it really erotic so far” As I responded he moved his hand down my body from my shoulder down over my pec resting it on my ribs.
He glanced down at my crotch being covered only by a pair of sweat pants. My erection clearly visible through the fabric. His hand continued down until it wrapped around my cock over the pants. With a smirk he said “someone’s excited”
