My GF Sister and I Part 2 [MF]

Since a lot of you guys asked here’s the second part of the storie

A few days after our couch adventure, I was back in my girlfriend’s apartment and of course her sister was there too (let’s call her sister Kaitlyn, obviously not her real name).

I had spent all afternoon in the bedroom with my girlfriend, when it was close to midnight she fell asleep and I carefully got up and went to the kitchen to get a glass of water as usual. When I was coming back Kaitlyn appeared, she was wearing a tight and very transparent shirt and a tiny short. She smirked and called me to go with her to her bedroom to watch something on netflix, she said that seh watched a scary movie and was too scary to be alone. My girlfriend has a extremely heavy sleep, so I didn’t worry and followed Kait.

My GF sister and I [MF]

First of all English is not my first language so I apologize for my grammar mistakes.

The story started about 5 months ago, my girlfriend has a beautiful skinny sister with big breasts, a beautiful ass and a wonderful face (my girlfriend is 23 years old and sister 19). They share an apartment downtown and for obvious reasons I’m always there. Some time ago I noticed that whenever I was in the apartment, her sister would not take her eyes off me and was always making an excuse to be around. One night we decided to see a movie in their apartment and she soon joined us. Somehow she managed to get me between her and my GF on the couch, it was cold and we all shared a single blanket. About 20 minutes later my girlfriend slept and it all started.
