We went out to the bars and hung out and after the bars we all decided to go back to their place and have the drinks keep flowing and so we did. Slowly everyone started going to bed but me and my friend’s sister decided to keep chatting. And one thing lead to another so we started making out and that’s when she grabbed my cock. I was shocked but drunk and horny so I honestly didn’t care. We were on the couch so I grabbed her hair and started to throat fuck her as hard as I could. She had little to no gag reflex so she was almost taking my entire cock. She was gargling and getting spit everywhere (I was so turned on). She was stroking my cock and licking my balls and kissing my taint. The shit part was she was on her period so we couldn’t fuck but I made her throat my little hole that night. She made me bust and she choked on all the cum I had and I stuffed her throat in my cock until she couldn’t breathe and gasp for air. My friend never found out thankfully.
