& varied, although primarily the wife & I favor opposite sex some of our Bi experiences for me at least (her as well) have been some of my more memorable, one for example a earlier partner, female & I used to work together & both of us had the hots for another worker, a guy that worked in the same place, she always wanted him to fuck her thinking he had a huge cock, he came home with us one time to fuck her, he wasn't what she hoped for but I really wanted him to fuck me.

He struggled some days with work there was a lot of pressure in that work place, I invited him around again so he could relieve himself inside me, he went to the bedroom with my partner both striped off & chatted while I went off to wash out, I went into the bedroom, my partner started fucking herself with her dildo while she watched me sucking his cock hard, I lubed him up & bent over & he started fucking me hard, his balls slapping on me.

He fucked me for a while then I heard him moaning just before he exploded inside of me, filling me with his warmth, my partner exploding in orgasm watching us at that moment, he kept thrusting until he was empty & started to go down, then pulled out of my ass his cum running out over my balls, fuck, so sensual, we had him over many times.
