I’m not bi but I really enjoy making other women cum using my fingers. I believe that I have a really good technique and I like to show off my skills. I do not want to jump in bed and have sex with these women, I just want to masturbate them till they cum. This is what makes it an awkward question. I have masturbated a few strangers but it gets awkward once they cum, because they are expecting more after they come or want to play too. I have done it to a few of my friends and some of my husbands coworkers’ wives, but asking is the hardest part cause it’s awkward explaining what you want to do. It’s almost always at a dinner party when drinks are involved, so it’s like I’m performing a magic act in front of a crowd. “Watch me pull an organum out of your wife’s pants. My question for the group is. How would you react if another woman asked if she could make you cum. Straight women would you be willing to let another straight woman giving you an orgasm? Men would you be ok letting a woman make your wife cum knowing that that was as far as it would go?
Certainly, why not? If the two women want to do this together it's their choice. No one else should interfere. If it stopped at masturbatory orgasm or continued further who is to say other than the participants when it should stop? No one IMO.
I’m a straight guy. If my GF wanted to get it on with another lady (with or without my presence), I would not feel threatened. As long as I got my time with my sweetie, I would not be jealous of some other lady getting hers. Some other guy with her, on the other hand, that would make me VERY uncomfortable. When I licked her pussy, all I’d be able to think about would be that some interloper’s dick had been there. It would put a tremendous strain on our relationship.
I’m a strict believer in 100% absolute and complete monogamy. My wife would never go for that, either. No matter how many glasses of wine were involved. Regardless, it’s still a very hot story.
I discovered the joys of e masturbating women as a teenager and to this day live to make a woman cum multiple times while masturbating her before sex. I wouldn't mind watching a straight woman do my wife as long as she is cool with me watching and taking care of myself. Even better if you'd let me try your technique on you at least once.
