My bisexuality... My cousin

THIS WAS VERY RARE IT WAS MY FIRST TIME WITH A MAN I am a boy this happened two years ago when I was 18 just turned I always saw that my cousin had videos on his cell phone porn and always saw him looking at me when I got out of the shower one day my parents decided to take me on vacation to my cousin's house and I innocently thought they were going to be normal and quiet vacations for two weeks a Saturday night my aunt and cousins went out to dance or to a casino I stayed with my cousin alone in this I slept in the living room on a mattress watching TV to sleep that same day I looked at porn to masturbate as I like it always shave my penis and the Booty I like feeling the skin well smooth in this just my cousin arrives and sees me quickly put my penis inside my underwear my cousin makes himself out to be stupid and says this is good, that movie looks stays on the couch next to the window in this my cousin tells me goodbye, don't forget to change the channel and turn off the TV when he leaves I go back to masturbating and see that my cousin was spying on me but didn't say anything because he was scared since my cousin is five years older than me and when I put myself sideways to touch myself sideways feel my cousin snuggled up next to me and says do you want me to help I tell him okay and he touches my Booty and balls making me even more excited although I take his hand off the Booty and told him I didn't like it (I had a lot of fear so I took it away) he undresses in front of me and tells me you like how I do it I tell him yes because he has a penis that measures 25 cm in this he gets back on top of me with me touching his chest and making him suck my breast I get excited so much that I let him put his fingers in my Booty in this he tells me how beautiful you are, all shaved after that he grabs me and says let me do it to you I tell him I was scared it would hurt him and he says wait gets up brings a stimulating gel and pours it all inside the Butt and a little at the tip of the penis that sucks my side of the penis and tells me you're mine all mine and I moan from the pleasure of being excited by the penis. Then, when he hears me moaning, he goes crazy and opens my legs and starts sticking it in for an hour without stopping and I'm moaning and screaming until I fill up my whole ass with cum. He tells me if I want to be his boyfriend or his cousin boyfriend. I said yes. And then he lets me do the same thing to him today, every time we see each other, we laugh when we're alone, we touch ourselves but we are the best cousins.
