yesterday i went to my friends house to go swimming. and she asked me to get some towels from up stairs. so i go up stairs and get them and i see her brother we start tlking then i give them their towels and then he asked me to come back upstairs so i did and we start to have sex. it was amazing out of all the guys i had sex he was the best i think its becuz he is 18 and older than the other guys i had sex with and he is soooooo hot . and the problem is my friend dosent like her friends to go out with her brother or have sex with him. so she will probally be mad at me for doing that. and she asked me what took me so long and i said i had to call my mom and use the bathroom and she bought it. but the problem is he wants us to sneak and do it again. i kinda do want to because he was sooo good but i would fell worse then i already do. so should i do it again with him? o yea and we only been friends for 10 months. and should i tel her
