The first time we ever experienced this was during a MFM threesome. Hubby has seen and been with me in threesomes with both women and men (we are swingers) but nothing significant between the guys ever happened. I had actually wondered about him with another guy and the thought for me was a turn on but I did not know if he had any bi inclinations himself as the subject was never brought up.
One night during a threesome, my husband was on top of me fucking while or partner whose cock was coated with my pussy was kneeling next to me while I sucked him. We all three had smoked a generous amount of cannabis beforehand and were extremely horny to say the least. My husband was leaning in, clse watching me suck and on a whm I offered our partners cock to him, which he greedily sucked in. Neither man flinched and our friends hand when to my hubbys head urgin him. I swear it felt like my hubbys cock became harder if possbile. In a few moments our friend announced he was going to cum but my hubby didn't move. He buried in me balls deep while our friend exploded in his mouth and throat. Not long after he came in me as well. Since then we have branched out into this aspect. My husband is bi passive (he can take it or leave it) but for me it is exciting to watch him with a man as it is for him to watch me with a woman![]()
SO HOT, I think I'd like for it to happen like this, too.
