A little history about my gf (24) and myself (26): we at the end of 2020 decided we would try a threesome (mff) and my gf absolutely loves them. She is extremely bisexual and loves extremely pron-like threesome sex.
Around February we decided that we wanted to go to Vegas with a group of friends for spring break. Us being how we are decided to jump on tinder to find us a unicorn and after a couple days of searching we found this beautiful tall girl who was new to the idea of a threesome. After getting comfortable with the idea of all of us having a threesome, we talk, in particular, about kinks and what we like and our third tells us that one of her fantasies is to be fucked with a strap on by another female. We stay in touch up until our trip.
Since we are with a group of friends we just tell them that she is our friend. 3 people in the group knew she was our third and the other 7 didn’t so it was a little fun to keep that a secret. All of us as a group hit up a bar and go to a strip club. After the strip club is when the magic happens.
