Reading 60's stuff about using obstacles to create tension: "you're lucky your friend is here or I'd be fingering you"

Was thinking of an analog for for when she says she has a boyfriend.

"You're lucky you already taken or I would: tear. you. up./be fingering you / be tearing off your clothes / be pressing you against that wall

I know this will create tension but I don't know if its tension that I actually want to create. What would be the effects in terms of

- becoming an emergency dick for her if she breaks w/ BF
- becoming the-BF-she-makes-wait material vs one night stand material
- social consequences of saying that on a college campus
- BF destroying

1. Possible but I don't think this will happen.
2. When going hardcore sexual she probably won't see you as boyfriend material.
3. When she tells the whole campus well yeah, girls and boys will know who you are.
4. I don't think this will happen. Most girls (but also boys) who cheat return to their LTR lover.

the fact that you're telling her that she's "lucky" to have a boyfriend or else you'd tear her up is pretty creepy imo. Makes you sound like a serious predator

yeah i mean

the quote in 60's book - you're lucky your friend is here or I'd be fingering you

that's pretty predatorial too

evidently there are times where it is good. Crude stuff. I dunno if its just high risk high reward like GM style and I should accept that but honestly I haven't tried pushing the envelope on what I can do and say sexually very much and

Part of me WANTs to learn how far I can push things but another part is thinking fuck this is crazy I'm going to get slapped and become the weird guy.
