Oral of my best friend’s cousin while she masturbates [FFM]

My boyfriend has an ongoing fantasy where I have sex with someone else. He has told me repeatedly things like how he wants to see me make out with another guy and other situations.

This happened Just before the lockdown but I’ve retold parts of it to my boyfriend so many times I feel like it was just last week. He got me to write it all down to jerk off to, and I finally got around to posting it here.

One of our friends applied for convocation early by overloading in the fall to graduate in the winter so we did a New Years / Grad get together in a house she shares with her cousin and her cousin’s boyfriend that I’ll call Liz and Tyler.

We’re socializing with everyone, it’s a big party and I end up talking with Tyler a lot. The conversation eventually gets flirty and when I call him on sneaking a peek down my tank-top, he says that he would love to see my tits if only my boyfriend would let him. I’ve known Liz since my first year of undergrad and didn’t quite believe him. We went to her bedroom where she was busy writing applications for some summer trip. Tyler was still joking around and didn’t seem worried at all.
