My Girlfriend [f] Sucked My [m] Dick With Her Sister On The Top Bunk

So for some background, this is my very first post. I am a 21 year old male and my girlfriend is 20. She is about 5’8 and has some really nice tits- I’m talking a 36DDD- and a great ass that looks amazing even in the loosest pants.

A couple of weeks ago, I was spending the night my girlfriends house, which is a studio apartment that her younger sister also stays at. My girlfriend, who I will call “Indica” because she’s a pretty big stoner, now lives with me so things are even more interesting. Anyways, I’m a pretty horny guy and we were getting ready for bed but I knew I couldn’t sleep without getting some sort of action. After all, we hadn’t had sex in a few weeks because of our busy schedules that weren’t coinciding. We were already cuddling so decided to grab her chin with my fingers and began to makeout out with her. I started to feel her entire body and felt my cock twitch the second my hand touched her boobs. They were so soft and I could feel her nipples starting to get hard as I moved my hands across her body. She let out a soft moan as I caressed her pussy over her panties. I suddenly realized that we couldn’t make a sound because there was just one flaw in my plan- my girlfriend has a full over full bunkbed and her sister was already laying on the top bunk.
