My 18 yo niece lives with me , I made the basement into a large bedroom for her. She goes to a local college and worked part time. She has her boyfriend who also is in college and works. He’s over daily and they seem to be getting along fine, they’ve been seeing each other for about three weeks now, they’ve other night he came over and we all watched a movie, they’ve other night were snuggled under the blanket and I could see her twitching every once in a while, after a few minutes they said they were going downstairs.

Once the movie was over I went down to start the laundry, as I walked past her room to the laundry room I saw her door was mostly opened and he was hitting her doggystyle in her bed, he was smacking her ass as his cocked tore her pussy up.

I watched for about 10 minutes before he collapsed on top of her after he came.

I started the laundry and went back upstairs, shortly thereafter I turned the TV off and heard them at it again, they continued for quite a while before they came upstairs and said they had a question to ask me? They asked if he could stay tonight, I had no issues and they returned to the basement , upstairs was quiet and I heard him say now we can play all night.

They made my night.
