Last week I was with my girlfriend and before we went out she needed a shower. Right after she got in I wanted to surprise her, so I stripped naked and snuck into the bathroom. I sat down on the toilet and got hard then started masturbating while listening to her.
I sat there and stroked slowly for about 15 minutes until the water shut off, and when she opened up the curtain and saw me, she shrieked and shut it quickly, then started laughing when she realized it was me and what I was doing. She then got out dripping wet, grabbed her towel and started drying off in front of me, bending over and wiping off her breasts. She was having fun with it, and I was getting hornier and hornier watching her.
At one point, she bent over my lap and let her long wet hair fall onto my hand and penis. It was cold, but it felt amazing. She was about to put me over the edge, then she put her damp foot on my leg and started running the towel between her legs. That part did it, and I clinched the rug with my toes and shot my hot cum all over my chest and hand. She giggled and sat in my lap and started kissing me, all with cum still dribbling out of my penis. Even though she was freshly clean, my cum was getting smeared between us.
After a few minutes she grabbed her towel and cleaned both of us off, and even though we didn't have time then, later on that night we pleasured each other in just about every way we could think of.
