My wife has always been fairly anti-bi, male or female. During a mfm, I kept getting a cock shoved in my mouth. Talked with her later about it, said wasn't bad, she didn't have much to say about it. Next time we had a mfm, different man, they were in a 69. I bent down to kiss her, she took his cock out of her mouth. We kissed, she was still holding his cock -I took her hand, aimed his cock towards my mouth, and went down on it. We ended up sucking his cock together in turn, and kissing with it between us. Afterwards, on the way home - she said - "that made me hot". Win-Win...
