Gf Sister

Threw a surprise party for my gf graduation with three of her siblings. We were prepping and ended up taking a few shots. While two of them were out buying food, I confess I was blowing her youngest sisters back out in her home. My gf is 5’4, d cups boobs, gorgeous peach butt, 120lbs ish. Her sister is 5’3 110lb ish b cups boob, bubble butt, tan skin.

She was acting very flirty and touchy and kept mumbling on about how she envied that her sister always seemed happy around me. I told her jokingly it was because we have lots of rough sex all the time. She came up to me, and started grinding her butt on me, and said she don’t believe it. I said okay let me show you so I bent her over a table and pulled her leggings down. I rubbed the outline of her panties and massaged her wet pussy. I massaged her pussy with my cock and noticed it was a little tighter than her sister. I penetrated and it felt like a really tight warm condom. Her pussy fit like a glove on my cock. Her sister usually creams on my cock but she seemed more watery. I went slow and deep and then started punishing her and kept feeling water down my legs. She kept saying my pussy better than hers haha, so I pushed her off and said f u you slut.

I had to stop because I started feeling guilty.
