Reply: my step brother

I'm an 18 year old female and I've been having oral sex with my 19 year old step-brother.

The problem is that he is much better then my boyfriend.

Yea. I did it. I am str8 too but my step bro and i started to play with each other when i was 12 and he was 10 and HE started it. He was always trying to look at my cock when I was getting outta the shower or gettin changed. One day I said "IF you wanna see it then there it is" and dropped my towel standing naked in front of him. He came by me and bent down to look at my cock which just made me hard. He smiled and grabbed my dick and started to jerk me off. I could see his cock gettin bigger and showing thru his pants. I dunno why i did it but i unzipped his jeans pushing them down along with his boxers and his little dick springed up. he had some cum around the tip of his dick so i rubbed it into the head. i didn't have any cum when i was his age so i spose he was more mature or something. the more i rubbed the tip of his cock the more cum was coming out which made me real excited. he was still jerking me off and it took about 2 minutes for me to jizz into his hand as he kept rubbing me. i was still feeling his cock tip when his face went all screwed up and i knew he was gonna shoot. i did it more and more until some more cum came out and he went limp. then i started to feel guilty about what we had done and told him it can't happen again but the next day he came in my room asking if we could do it one more time.
we both got our of our cloths and were jerking each other off. then he wanted to rub our dicks together so we did. the i pulled him close to me so both our dicks were pointing up but touching and i jerked us both off at the same time util we both jazzed on each other even though he didn't have much. this went of for a couple of years till i was 14 and got a girlfriend. even after that we still did it sometimes. now i'm 18 and still feel a bit weird about it

First off i would like to say that i am a 16 yr old male, and i consider myslef straight...but sometimes i have thoughts about doing stuff with my younger step-brother...we have done alot of stuff like jacked eachother off,and sucked eachothers dicks, but after i cum, i feel weird about it, i tell him that its not right, but weeks later i end up doing it again with him and he really likes it...whats wrong with me. i am 16 and he is 12...i love girls, but i enjoy playing with him...i only feel weird afterwards... anybody else do it
