I masturbate to this experience regularly even though it happened some years ago now.
When I was about 14 or so i started to realise i didnt want to attend the local church services instead so i would have a lie in on sundays.
One weekend my uncle Harry was staying at our house and not being at all religious he also decided he would stay at home. That morning I had a lie in and then went to the bathroom for a shower, thinking that Harry was still in bed i left the door unlocked as the room gets very steamy otherwise. Once i had finished i stepped out of the shower and took a towel. as i did so I heard a cough and turned around to see Harry standing there completely naked with his hand round his cock and his other holding a glass of ice and water. I was shocked but he told me to relax and he was going to show me a good time.
He told me i had a beautiful body and he had been fantasising about me all weekend. he asked me if i masturbated, I told i did occasionally but didnt really know much about it. With that he pulled my towel away from my warm, clean body and pushed me to the floor. he started to rub my clit and kiss me. He told me he wanted to french kiss which i did because i was getting so incredibly horny. Soon we were getting bored of just that but before i said anything harry stopped for a drink and took an ice cube between his teeth - he rubbed it up and down my body. Circling my nipples which were getting as hard as rocks and then moving down to my pussy. The contrast of ice and hot skin was amazing. Once we had finished playing he got me on my hands and knees and entered me from behind whilst feeling my supple breasts. we were both moaning so loud and shouting each others names, It was amazing. he came all over the floor and my breasts which he told me to lick up. I did eagerly. We then took a shower together where more fun occured.
He went home that aftanoon and havent spoken since!
