<human>: Ok, so I'm out on Halloween, and my mates decide to meet some girls, I don't know them and I'm not anti-social so I was like yeah whatever, and the people we meet are people that I've seen or have heard about, one of the girls like me but I'm not interested in her, ok so about 15 minutes later after sitting in McDonalds one of my mates friends starts flirting with me, I just flirt back without really thinking, so we go into a park to hang out and there's a swing, the girl I was flirting with calls me and tells me to sit on her lap, so I go to sit on her lap and she's just cuddling me from behind and puts her head on my back, I'm just like ok so I just start kind of rubbing her leg in a seductive way, I get a boner so I kind of pull of not to get embarrassed, then she pulls back on me and then she feels my dick, she doesn't say nothing and just holds me again, I could feel her hands on my dick while I had a boner, in my head I was just thinking what a fuck up, after that I had to leave so we're walking back and she walks next to me and we just talk. 
Btw she's a solid 7.5/10.

Can you give me the gist of the text in a nutshell?
<bot>: I sit on a girls lap for about 10 mins, get a boner she feels it, carries on touching my dick for a good 4 minutes before me making up an excuse to get rid of the embarrassment.
