TL;Dr : Girl says I'm too young to fuck her, says I'm butt hurt when I leave

Last night chilling with this girl. She's (22) older than me (19) and we know each other from work, went over cause she needed help with something. We drink and chill, talk about life (have done this once before and this is where I Neo dodge all the shit tests) then go for a smoke with her roommates.

Roommates were giving me crazy IOIs whole time I was there, like preening and walking around in skimpy clothes. This is probably what made her want me.

So we're outside and I tell her I'm heading out. She asks where I'm going and I hold frame (thanks trp) and say "to catch a vibe" and look off into the distance. Corner of my eye I can see both girls getting wet, couple of minutes later she texts me while we're smoking "can I use you for cuddles".

So I head in again, whatever happens. But as I'm escalating (I might have been a little intense cause I was drunk) she's kinda not fully into it. I ask her what's wrong she says "idk if I want to do this, you're so young". I say cool and move away but with her ass in my grip. Then she decides to suck my face off. Again try to escalate, no progress. So I say I need to leave, and she says "aww don't be butt hurt"

This has happened before as well, was talking to plate and she says some weird shit, I say I gotta go and she thinks I'm just in my feelings.

How do I show I'm not butt hurt, I just don't have the time to waste on her bullshit? I don't want to act like a bitch, I genuinely just have better things to do than entertain a bitch
