Cousin Visiting

Around the end of summer I had 2 cousin visiting from out east, both very nice girls and both are nurses. We were invited over for dinner on the lastnight before the left the next morning. All were drinking and hot tubing. As the drinks were going down smooth and the fun was picking up i went to mobe the car instead of doing it later just in case I hot too tipsy. As I went to get up and move the car one of the cousins Brooke said she was going to go video call her boyfriend back home. So I go to the car she goes to the room she is staying in. As i am returning to the party down the driveway a light in the basement turns on and I obviously look in through the window and I see broke taling on the phone and think nothing of it. I go to walk away but before my eyes turn away she starts taking her pants down revealing a black g-string and so now I am peeping on her. She is on the video call with her bf stripping for him, she is fingering her self with her phone on selfie mode. As she is doing this the part continues and I find myself in a trance and can't look away. She then pulls out a dildo from her suitcase and starts sucking on it then puts it in her pussy, this goes on for a minute or 2 then puts the phone down sticks the dildo to the wall and starts fucking the dildo doggystyle. I am in shock looking through the window my jaw dropped and am hard as a rock. She finished up and returned to the party as did I. I will never look at her the same
