First vaginal double penetration

I took the rest of the roll of film which had been an almost full… 36 exposures … and moved over to the dresser to change film. That’s when Dawn told me to forget that fucking camera and join them!! She did not have to tell me again I was already naked so I walked over and she motioned me to her and told me she wanted to try out something new for us. I said fine and asked what she needed me to do. She told me to get between her legs and see if there was any way I could shove my cock into her cunt with him still inside her!!! I know he’d heard the same thing I had and we looked at each other and kind of nodded like why not?
