Later in the evening when the last encounter took place Mari called me to tell me about Becca’s request. Her request was fairly specific, she only wanted to see my dick, she had never had sex and had pretty minimal experience beyond making out with guys. Mari told her she was ok with her looking as long as I was ok with it. Apparently their conversation took a turn and somehow Becca asked if she could watch us have sex. Mari again told her that as long as I was up for it she was open to the idea.
The following afternoon Mari called to let me know that she was going to be a little later getting home but that Becca was there and if I wanted I could go over early she would let me in. It felt a little too arranged, but I had nothing better to do so I headed to their apartment.
I rang the doorbell when I got there. Nothing. I waited for probably fifteen or twenty seconds and tried again. Still no response. Just as I was about to knock I heard Becca announce from the other side that she was coming [to open the door].
