I'll never forget the first time I ejaculated when I was masturbating. I had been masturbating for a while but always just had a dry cum never had anything more than a little moisture come out.
I was in the backyard at my house one summer and my sister had her friend Siobhan over. Siobhan was really well built and was filling her little blue bikini quite nicely. She also had a great ass but it was her tits that always caught my eye. Her tits were nicely rounded and she was showing quite a bit of cleavage that day. I was staring at her and had a million thoughts running through my mind of how great she would look without the suit on. Before long, I could feel myself getting very hard.
I slipped into the house and went to the upstairs bathroom because the window overlooked the backyard. I locked the door and took off all my clothes. I went to the window and stared out at Siobhan. I grasped by dick and started to stroke it slowly as stared at Siobhan's body. She just looked so great. I started stroking harder and faster. I could feel me getting ready to hit what I thought would another peak with the usual drop of moisture. Instead, I felt like I was exploding. I shot what seemed like tons of cum all over the bathroom wall and floor.
I never did get to do anything with Siobhan but I will always remember that day!
