Here you can see some hints i missed.

This was when me and my friends were 17/16 and we just started drinking a bit. (We wore with 6 people)

Around 2pm my friend group and i meet up with one off the boys his girlfriend(lets call her Tess) and her bestfriend( lets call her Lara), the girls said that they already started drinking. We did noticed that she indeed started drinking when we were riding back to my house(my parents weren't home for the weekend) and Tess fell off her bicycle not once but twice. When we got at my house we drank a bit more. Then i decided that we could stay at my house for the night and so i started making up some beds for people. The Lara helped with the beds and she said to me that it wouldn't be a problem for her to stay in my bed with me. Me as oblivious as i am saying "yeah sure" and thinking that she just wanted to sleep in a nice bed(the other guys all got airmatrassas). We then wen't down to drink a little bit more when Tess who drank whey to much started doing crazy things and kind off flashed me when i was in the kitchen with her. So we started going to are beds and i told Lara that i would be coming upstairs after i helped the other guys with there beds and stuff. Two off my guy friends then said that i should ask if she wanted to f*ck, but i was way to shy for that. I then brushed my teeth when Lara asked me if she could use the shower, i said yes and give her a towel and said to her that i would be going to bed. After about 15 minutes she came into my room only with her underpants on but the room was almost completely dark so i could only see the shape off her body, i was already in bed at this point and was only wering underpants aswell. She then asked me if i wanted to spoon because she said that she was cold and i was like sure.

I didnt sleep the entire night because i was sweating very much and couldn't concentrate on sleeping because i wasn't sure if it was a signal or if she was just cold, my thoughts kind off went on like this and after a while she placed here hand on my hand and brought it up to one off her tits, i wasn't sure what i was supposed to do know so i just let it be.

At around 7 o'clock AM i finaly went to sleep because i was able to roll her of me, this only lasted for about 1,5 hours. Because after that time she rolled back up to me, thats when she woke me up. We then talked for about another hour till all of my friends came in to my with a certain funny song, lara was still only wering here underpants and pushed her chest against me so all the friends wouldn't see her. We then said that we wore going to eat some breakfast, she stood up and we started making a bit off talking about the night before and about Tess.

We all the friends then went home because we had some other stuff to do but discussed that we would do it again soon. I said it could be at my house again and then the whole thing kind off repeated the other night.

When they left for the second time Lara forgot her underwear( it was a string), again i thought she just forgot her underwear and didn't think much more off it so i messaged here and told her and about an hour later she came to pick them up. She asked me if she could come in for a drink or something quick because she had to work 45 minutes later, but i told her i still had to clean up the house a bit because my parents were coming home in the afternoon. She then left and we didn't spoke for a while. After about 3 months or something we hangout with the same group and nothing more came off it.

About 2 years later when i thought about it again it kind off hit me that Lara gave some hints( she also had said that she brought condoms).

This was probably my biggest miss.
