My best friends bro

I was 16 and so was my best friend Kimmy. Her and I have known each other for 5 or 6 years. One night her brother Adam who was 15 at the time got my number and started texting me. Adam said I was really hot and that he and I should make out. He and I both knew that if Kimmy found out she would be sooo mad. So, Adam and I didn't tell her. 

So I spent the night at Kimmy's house. I told her that I had to go to the bathroom to wash my face, brush my teeth... But her brother Adam came in and locked him and I in the bathroom. So he picked me up and set me on the bathroom counter. We started making out and feeling eachother up. Adam and I were both virgins by the way. Kimmy had never kissed a boy, never held hands, never been on a date as where I have done all that. Adam had just kissed girls and held hands. 

So anyway, Adam and I were getting really horny and so he took my bra off and lifted up my shirt. He then started sucking on my nipples and caressing my thighs. Then I got off the counter and stood up while kissing him. I grabbed his rock hard penis and started fondling him through his shorts. I pulled down his shorts and under wear and stroked his penis eventually giving him oral sex until he came on my face and breasts. Adam loved it and wanted more. Adam picked me back up and put me on the counter again. He moved my shorts and thong to the side. Adam rubbed his penis over my soaking wet pussy, as he was still hard despite shooting his load on me. He kept rubbing his penis along my slit and teasing my clit which was now really exposed. It was driving me crazy so I started rubbing my clit like crazy as he rubbed himself around my pussy hole. Quickly I orgasmed and began rubbing his still hard penis until he shot another small load of cum into my hand. Eventually he left the bathroom and I got cleaned up and went into Kimmy's room. She never knew what happened to this day.
