Consensual sharing by all parties involved is such an erotic experience. My wife once lent me out to her girlfriend.
That is an amazingly sexy story
I am male and have watched a very close female friend masturbate to orgasm as I held her legs open.
On another occasion we arranged for me to watch her and her BF in a hotel room by acting as room service (I had a key), leaving a drink for them on a table as they fucked and pretending to leave, but staying in the room in the near dark & peering around wall to the en-suite bathroom to watch them fuck
So this story hopefully represents the next step where I join them..... soon I hope
