Please help! i really like this girl but i think our friendship is ruined!! help!!?

NOTE: SORRY ITS SO LONG I JUST REALLY NEED HELP ON THIS!

Okay so first off let me name everybody, the guys: me, Eric, and James (btw the guys are 17)And the girls: Desiree (the main girl in the question), Monique, and Alexis. (girls are sixteen)I like Desiree A LOT but like I’m not like some guys who will just like a girl for sex. That’s what it seems like when you hear this but I promise you I’m not and btw it also may seem like Desiree is a whore in one part of this but she is a really sweet girl so please don’t judge her or me. Okay so for my birthday my mom got me a condo or whatever that me and my friends stay there during the weekend and over the summer. So last night, everybody but me and Desiree had to go to work the graveyard shift at their job (me and Desiree work somewhere else) so it was just me and her. So we were sitting on the couch watching tv and she told me she was hungry so I took her out to eat. And when we got back it was kinda late and she went upstairs. So after about 10 minutes I went upstairs to ask her something and the door was cracked but I couldn’t see anything so I slowly creaked the door so I could see and I saw her you know..masturbating. so I was just gonna walk away when I heard her say “yeah f*** me harder Cameron! Harder!” and I was thinking through my head “why is she screaming my name?” and I got hard listening to her and I needed it to go down and so I started jerking off. And I was about ready to come and I heard her say “oh my god Cameron! I want your hot creamy come all in my mouth! Uh! I want it!” and without thinking I walked in and said “oh god take it then!” and she opened her mouth and sucked me hard. And I came in her mouth and she swallowed ALL of it. I was actually kinda impressed since I come a lot. Then just realizing what I did I ran outta her room and didn’t talk to her for the rest of the night. So this morning, when they all got home she came downstairs and didnt even make eye contact with me. Alexis was asked what we did last night and this was her reply: “nothing really we just got something to eat and came back home and we watched t.v for a couple of hours then I went upstairs and fell asleep.” And Eric asked me, “and what did you do when she fell asleep?” I said “same as her, fell asleep” he just said “oh” suspiciously (the guys know that I like Desiree) so they went upstairs to sleep and Desiree was going to eat a pop tart or something and I looked at her and said “can we talk?” she asked “about what?” I told her “abt last night…” and she just said nervously “i-I’m gonna…go upstairs” and ran quickly to her room and I walked up there to see if she was okay and I heard her through the door saying “im such an idiot!! Why did I do that!? He probably thinks im a effing whore!!! Now he’ll never like me! Oh my god I hate my life!!” and I heard her kinda crying. And she just stayed in her room and said she had a headache but I knew what was wrong. Then I got pissed off and went for a run when I got back she was out of her room but she still wont look at me or talk to me or anything. I don’t think she’s a whore I still think she’s cute and funny girl she’s always been.

I kinda also think she started being sexually attracted to me about two weeks ago when sometimes I got huge boners (still do) just by looking at her not in a sexual way but I just like her. So we all were out in the yard kidding and joking around and James pushed her down and she grabbed me and I fell with her and everybody else fell too. And her hand was on my crotch but I don’t think she noticed and she kept moving and laughing and her hand moved to and I was trying not to moan or anything. And she was laying next to me and stopped moving but still laughing and she kinda squeezed my crotch and said “oh wow!” and I swear I heard her say under her breath, “so big” or something. I seriously am not making this up.

But I just wanna know what to say to her because theyre working again and leaving at 10 tonight. Im afraid of what to say to her or if she hates me or what. I just need help. I really like her, I don’t know if she likes me, but I know for sure that I like her and don’t want to lose her. Please help!
