She preferred mmf first and after she try then onli she allow mff. We haven started any yet as I worried she will like the feeling and permanently fucked by some other guys like what bro sadfa said.
Might change plan now instead of mmf, perhaps I could blindfolded her, tied her up, pretend to have some role play with her and have my fren to fuck her in front of me without letting her know and once he's done then my turn
she doesn't has much experience in sex, sometime I lied her that I wore condom but actually I didn't and she didn't even noticed when I cip so I guess she wouldn't find out she is actually fuck by another dick
Well, let's see and will update further if any.
