I have a crush on my brothers best friend

So for anyone who didn’t read the last post here it is

So be prepared this is going to be super long!

To start out my questions are if he truly does want to be friends with benefits (because that’s really all I want or what he’s doing) also what I should do about it.

My brother is 26 and I’m 18. So me and his friend are 8 years apart. His friend and him have been friends since I was a baby and at first I didn’t think of him as a friend or another brother because he just never acted like a brother. Anyways a little after I’ve turned 18 he’s been REALLY flirtatious and we’ve gotten closer but he’s been especially like this the past 2 days. So on Saturday my whole family including him and my brother went for a family get together. While we where there we both got SUPER drunk we had a ton of shots and drank some beers. So I was up dancing with my cousin and I walk over to him eating some candy and he starts to play with my bra he asks me what this is and I say it’s my bra and he stops. Next on his way out he smacks my ass not noticeably to everyone else but noticeable to me and says “see ya” I shrugged it off because we where both drunk and I thought that’s all that was. The next day I posted a picture of us the night before and he dms me “ straight baddies😍😍” as a reply to the picture. We talked for a little bit about random stuff and a little while after that he came over but I was asleep. I’m usually a heavy sleeper unless someone is looking at me then I wake up so I woke up and he’s standing right over me staring at me. He starts to walk away and says “ I thought you where dead don’t die ok” then I get up for a second to go get water and he’s in my spot laying down so I sit on the couch far enough away from him that I can lay down. Anyways he started out with his feet on his side of the couch and slowly he gets them to my side and starts hitting my ass with his foot. Then he gets it under the blankets and starts to rub my ass and get closer to my vagina. Then it all stops suddenly and he gets up to leave and go find his keys but they where in my moms car so i walk him out and as he goes to leave he cups but only lightly the bottom of my boob and says “ bye loser”. All this is obvious he wants to fuck but then I posted a little friends with benefits thing and he said “ yo chill” like wtf does that mean. I’m confused can anyone help me!

Now here’s the update-Ok so here’s what happened this weekend (note we don’t really talk besides when he’s over we talk a bit but not much and nothing huge) on Saturday my brother, my dad, him, and me went to a dodger game we didn’t talk much but on the way home we both fell asleep and I ended up on him arm when we got to the house he rubbed my check and told me where home and then we went to bed that night. Later that night my brother and him went to the casino and didn’t get back until around 6am. When they got home my brother went straight to bed but Andrew (my brothers friend) came to my room I was asleep (of course it was 6am) and he put his hand on my butt note I only have underwear which should be counted they where for real a thin thong, and started shaking me so I would wake up. I can’t remember what he said but I know he did say something then he put his fist out so we could pound it. A few minutes later he came back and woke me up the same way again then left again. At this point I was asleep but not fully and just as I was finally getting there HE COMES BACK IN and lays on my bed. He said the dogs where jumping all over the couch where he was trying the lay down. Let me just say like god anytime I see him I literally want to pounce so imagine when he’s in my bed and I have no pants on I was going insane. Anyways as we both start laying there he goes to sleep because he snores in his sleep I know when he’s actually sleeping and then we wakes up and AGAIN starts pushing on my butt with his hand and tells me to move that I got to sleep so it’s him turn. Then he takes his head and starts trying to put my butt with that. I had to get up anyways and honestly if I stayed it wouldn’t be much longer till I would start acting on my thoughts😬. Anyways by the time I came back from my shower which was no more then 10-15 minutes he was back on the couch. I’m still not sure what’s going on here and I’m terrified to do anything because if he’s just doing it just for fun then our friendship is ruined and my brother could find out. At this point I’m not sure what to do or what he’s doing and it’s driving me insane!!! Can anyone help!

FYI this is him and I
