My parents separated when I was ten and I was sent to a boarding school that year while they worked things out. At boarding school, it was a military style school, we had marching and calisthenics, we had group showers, and communal meals. The school started with third graders and went all the way up to high school. Elementary was housed in a separate building.
I had a roommate, who was twelve but held back, and when we showered he gave me the soap and I had to wash his penis. The soap made it slippery and I pulled on it gently, taking my sweet time because I liked to wash his penis. After the shower he gave me his towel and I would dry his penis. After it was totally dry I would lean over and kiss it. This was every day and I looked forward to it. I really wanted to wash and dry and kiss his penis.
Well one afternoon after homeroom, we were both back in the room and he pushed me on the bed and got on top of me and started humping. My legs opened up naturally and I felt his erection rubbing up and down my butt crack. It only took a minute for me to push my pants down and for him to push his down and his naked penis was rubbing along my naked butt crack. I was hard against the blanket holding on hard to the pillow. He was poking trying to get his penis in when the door opened and the weekend elementary school director stood there. Caught us.
We had to sit through his questions and answers, he wanted to know how long it was going on and if we knew it wasn’t proper. Well I was quite and didn’t answer. He let us go with a warning. When we got away and we were around the corner my roommate pushed me against the wall and kissed me. That night after lights out he came over to my bed and had me kiss and suck on his penis, before he had me push my pants down and he got on me and this time he did achieve penetration. It always hurts a little, but it’s a good kind of hurt, the kind you want to feel. From then on until the school year ended I was his boyfriend and I kissed his penis and he kissed my mouth, and he got on my back and he inserted his penis in me.
I also was in a boarding school, ninth thru twelfth grades, second year roommate brought up touching each other one night and it sounded fun so we did in the dark. Eventually we worked up to giving each other head and some weeks it was every night. I have never been sucked off nightly again since graduating high school.
