So during rehearsing for a P.E. exam, to becoming a P.E. teacher, I (M25) was rehearsing with a groupmember (F23). We have never been sexually interested in eachother, but this one afternoon things got a bit heated.

We were practicing acrobatics and got a bit physical, a lot of holding, grabbing and body contact. At one point we collapsed and fair to say, I had to grab at something and I got a good hold on her curves. We decided to take a break at this point.

During the break, things and conversation got a little heated, and she did notice I had gotten quite the bulge in my shorts. Without a doubt she asked if I wanted to go get something in the lockers, and I agreed. When we got up there and closed the door, she told me to pull it out, she wanted to see it - So I did.

I ended up stroking as she got topless and dirty talked at me while I stroked, before getting on her knees and finishing me off with an extremely hot handjob. I ended up spraying all over her breasts and neck, before she simply gave me a surprised look and said 'good boy' - Hottest thing that's ever happend to me.
