I knock on her door

I knock on her door. But I couldn't here any reply. I try calling her but she doesn't pick her phone. I try to look in through the window so I can see her. But all I see is her phone ringing. I can't find her inside the house. I think she might have left her phone home. So I decided to wait for sometime outside her place waiting for her. But then I see her coming in a car with a dude from our college Sam. It was Sam the same guy who used to hit on her and she refused him for me. I decided to hide and watch what is going on. I watched them get out off the car and walk in her apartment. Before entering I saw him spank my girls ass but she didn't react that made me so angry. They entered inside and close the door. Suddenly I recieved a call from my Gf she said she was busy all day with her project and forgot a mobile phone at home so she couldn't receive my calls. I said sorry for yesterday and she said it's ok. But at the same time I saw her sitting next to Sam on couch and he had placed his hand on my girls thigh while she was talking to me on the phone. I was really angry at Sam as well as Elsa as she didn't hit him for that. I asked Elsa babe can i come over we can continue where we left yesterday and she said no She's busy right now and needs some time.....
