When I was 14 my sister had her mate Nicole round for a sleepover. I was masturbating in my room and Nicole was looking for the bathroom when she walked in on me. I was so embarrassed and she closed the bedroom door and told me to carry on. Nicole took her knickers off and handed them to me and told me to use them while she fingered herself. I came quickly into the crotch and Nicole had two orgasms while I got hard again. She was still horny and Nicole said she wanted me to f*ck her but we were only 14 and we didn't have any protection so I said we couldn't do that. She did suck me off though and I came in her mouth.
