Ok, so it started out as a little gift that was pretty thoughtful. My stepbrother (call him d) gave me a vibe for my birthday. I was like thank you so much. So I was in my room using it one day when he came in with a dildo and nothing on. He told me to take off my shirt and he said, "this is gonna be awesome." So he told me to stick the vibrator in my pussy and turn it on. I started squirting like mad. He got really horny from that and his dick went to like 6 in. erect! (Hes only 13!!) Next thing I know, he's eating me out, which felt great, and then he fingered me, too. Then I gave him a blowjob. Our parents are going out tonight and I want to do it again, so how do i ask him? I know he probably wants to, but I dont want to go to intercourse or stuff because i consider incest wrong.
