Standard disclaimers of everybody being over 18 etc
Back when I was 25 or so and living in Santa Cruz I was involved with a woman who was a "late" bloomer in the sense that she gave me her virginity after she graduated college.
She was tall (5'9") small breasted with pink pearls for nipples.She could have been androgynous if she ever choose to emphasize that. Lets call her J
I was 6'2" about 240 lbs. Think blue collar construction.
A year later she is sharing a house, and a bed, with me and another woman. They used to joke about writing newspaper advice columnist's to ask proper convention as to choose which of the others to go to bed with at night. As she said once. it was a busy year.
I always felt some sort of guilt to her for taking her virginity, teaching her to suck my cock, and her learning to eat pussy in my presence.
One evening when she was apt. sitting for a friend whose neighbor was a gay/bi man of same age group, who was not "flaming" just another guy who was out, neater and better attired then I this was the early 70's. I enjoyed his company as he was part of a greater circle of friends. He was androgynous before that term was widely used or acknowledged.
So one evening the three of us were sitting around with some good pakalolo and wine. The conversation continued to bump up. Somehow the subject of the sensitivity of mens nipples came up. I admired that I had sensitive nipples and enjoyed women sucking on them during foreplay. The gay man expressed a certain skepticism and my lady decided to show him by running her hand under my shirt and over my nipples while kissing me. Next thing I am aware of is my shirt is open and they are both sucking on my nipples. Needless to say i was expressing pleasure with some slow moans and pressing their heads against my chest. At this point the gates opened and clothing vanished.
At the time I thought that surrendering my oral and anal virginity to cock with her participation would help balance the sexual/ karmic balance. Plus it was feeling real good.
First with J's encouragement I slid down and started too going into 69 with the man and I sucked my first and only cock as J mounted his face in reverse cowgirl. I remember looking up and see a look of carnal voyeurism on her face that was almost scary.
Then I pivoted to 69 with him using his cock in my mouth as the pivot point.. Shortly she joined me in bathing his cock with our tongues and mouths. she kept going back and forth between our two mouths and two cocks sucking eagerly.
