Left a surprise

I've had something similar happen to me, me and my friends were drinking in the park, and I ended up getting really drunk and don't remember what happened. I guess I ditched my friends and ran off, I came to in my bed and my skirt was pulled up around my waist and I was face down ass up and some fat guy was fucking me, I think I had an intense orgasm and it woke me up because I was wet all the way to my knees, he only lasted a few minutes and then he ended up cumming inside of me and it kind of freaked me out because I've never had that happen before, or have sex without a condom, afterwards I found a bunch of receipts two places that I didn't remember going. And I looked in my phone and realized I met him on Tinder, I found a bunch of text that I sent him that I don't remember sending, the next morning I was late for school and I tried sneaking him out before my parents could see him but I ended up getting caught, I ended up coming up with this big lie, saying that I knew him for a long time and that we didn't really do anything and they believed to me.
