first kiss

So I'm really close w my best friend/new bf's sister {we're all the same age}. The 3 of us decided to have a Harry Potter movie marathon sleepover. That's totally normal cause I was just friends w him, nothing more. We had talked about maybe dating in the future, but we never really started anything. Anyway, all through the first 2 movies I was cuddling w the guy & the sis was at the other end of the couch. Then she went upstairs & we started making out. It was my first kiss tbh {I'm in college but I never actually had a serious BF}. So she comes back down and we both tried to act natural. Then I had dinner w his family & it was awkward af! We all decided to sleep in the basement together- me & him on the couch, her on the floor. In the morning we started making out again while the sis was there {on the same couch less than 2 feet away}. That lasted pretty much all day. & over breakfast his mom kept talking about how he needed to find a good girlfriend it was SO awkward loll 😂😂😂
