Sister in-law

When I was with my ex (24f) I would spend most of my free time at her house just relaxing, her younger sister (18f) always has had a thing for me. One day we were all chilling and smoking and my ex had to use the bathroom, her sister went and sat by legs legs and started laying her head down. Didn’t think nothing of it she always used me as a pillow when I was there.

Fast forward later that night my ex was sucking my dick, I had my eyes closed, when I opened my eyes I seen her sister standing in the door way playing with herself. I came then my ex went to bed. I tried to go to bed but kept thinking about the sister.

Next day, we wake up (I sleep in my boxers) and I go to use the bathroom. Well morning wood was definitely there and I didn’t notice my boxers had shifted overnight. So I’m walking to the bathroom and her sister opens her door to come out. Well she seen my dick an just smiled, turned around and closed the door.

Later that day, my ex needed to go to the store. So she did, well little did I know her sister was waiting for her to leave. As soon as she pulled off her sister walks out the room with only a towel. She asks me for help in the bathroom because the shower wasnt working, while I’m fixing the shower she whispers in my ear “I’m mad that she’s the only one who gets to help you cum” I turned around shocked from her saying that then I seen she had dropped the towel an was already on her knees waiting for me to turn around.

I turned an she immediately grabs my dick, she looks at me with big puppy dog eyes an asks “can I make you cum like she does” as soon as she grabbed my dick I wanted it. I said “if you dont tell no one and can make me finish before she gets back” she agreed pulled my dick out an starting sobbing all over it.

Needless to say she sucks dick like a goddess and made me cum 2 times before my ex got back home. Honestly waiting for her to text me and ask me to fuck since im no longer with her sister.
