I was lucky enough to to be the only male in a FFFM foursome.
My college years and I delayed graduation for a year to participate as long as possible.
I was living on the ground floor of a boarding house. Upstairs were three women living together. One lady was a 35-year-old nurse. The other two were nursing students.
As things started out, I was invited up for dinner one Saturday night. It ended up as a reoccurring orgy and fuck anytime two or more of us could find the time between classes and my part time job.
The older lady was a bi-Dom. The two girls were bi-Subs. They were all into Medfet. I was their willing patient, and they were very generous with their favors.
Imagine being a horny 20-something college student with an ongoing sexual relationship with three women and one of them being a very sexually experienced 35-year-old. Who wouldn’t put off leaving that situation?
They didn’t hide anything from me or each other. If I was having sex with one of the students and one of the others came it, she would say, “Don’t cum. I’ll want some of that dick after I get a shower.”
All of that action called for a lot of discipline on my part and the nurse was the perfect teacher. She would not hesitate share her considerable sexual knowledge.
In my case, she taught me about tantric sex practices while teaching the students about lesbian sex and the pleasures of anal sex. My being the instrument she used for their instruction and practice didn’t hurt either.
I called them my A B C girls because their names were Amy, Brenda and Carol. Amy was a petite blonde with small breasts but large nipples and aerolas. Brenda was a natural redhead with larger breasts and an ample soft ass. Carol was a brunette with an hourglass figure and the largest, thickest bush I had ever seen.
This was during the height of the hippie era and Beatlemania. Lots of hair everywhere and it was celebrated as a right of passage.
Our situation turned kinkier that group sex. The little devils made me their practice patient for any and every invasive procedure they were studying in class.
I didn’t really mind after awhile because Carol made sure I got to learn some amazing nursing skills, which I practiced on the students. They particularly enjoyed giving me large soapy enemas, prostrate massages and they loved playing with my urethra.
In return Carol taught me to perform vaginal and rectal exams and let me practice speculum insertion on Amy and Brenda as well as herself, which she especially enjoyed. I rarely had to use lube on any of them!
Sadly, like all good things, our time together came to an end. I graduated and moved away to begin my career, Amy and Brenda did likewise while Carol got a much better job in another state.
We all stayed in touch for a time with cards and letters but eventually we lost touch, got married, had families and moved on with our lives.
