I let my friend watch us fuck and she masturbates while we do it.

When I met her, I'd just started dating my then-boyfriend, and she immediately told me how attracted we were to each other. She said she loved our bodies and joked that she wanted to see us fuck. I took it as a joke and didn't pay much attention. Until the day came. She stopped by for a drink after a date to tell me all about it. Well, one drink turned into two, and two turned into way too many. The three of us ended up on the couch, very drunk, talking nonsense and joking. That's when things got a little too heated. She started talking again about how sexy we were and how she wanted to see us fuck. This time, however, she said it in front of my boyfriend. I looked at him to see how he reacted, and I could tell he was interested. I told her I'd put on a show for her and got down on my knees, giving my boyfriend a blowjob. She started touching herself through her dress, until she finally pulled it up and started touching herself right in front of us. It was incredibly hot. She held a glass of wine in one hand and kept touching herself with the other while my boyfriend moaned and I gave him a blowjob.
