[MF] Wife’s sister naughty video call

So I’ve had a thing for my SIL for years now. Me and my wife are happy enough but our sex life has taken a dive and the SIL has always been very flirty with me.

So last night I was feeling brave and after messaging the SIL about Xmas presents I decided to “accidentally” video call her while I was in the shower.

I placed my phone on the ground in a way that it looked like it could have been an accident, hit the video call button then jumped in the shower. I’d angled it so she could see pretty much all of me from the neck down but not my head or face, that way I could watch it to see her reaction.

She answered the call, at first I could see she was trying to figure out what she was looking at then her hand went over her mouth in shock…but she didn’t hang up.

She just kept watching.

So after about a minute of just washing myself I was getting really hard and decided to start jerking off to see what she would do. She watched me all the way until I finished.
