You're woken up by some loud whimpering

In the middle of the night, you're woken up by some noise next door, you can't seem to go back to sleep so you decide to check it out.

You knock on the door and on the other side is Bianca and Aiko, by the loud moans and whimpers from before you could conclude that they were probably..... fucking.

Bianca , Aiko

"I'm sorry I didn't mean to bother whatever you guys were doing but could you please lower down the noise? I can't sleep" You ask nervously. "Oh of course dear, it's just my friend Aiko here can't seem to handle me so she's been quite loud, we apologize, thank you for telling us." Bianca answers.

You walk back to your room and get on your bed, but no less than 10 minutes later, they're back to being as loud as before. Not able to sleep, but also too nervous to knock again, you deal with their noise. After a while of hearing all the clapping and moaning, you start to get horny. "Fuck... the last time I fucked a dick was during the 1st round with that freaky hung guy.. but I did all the work and didn't even finish... The girls next door seem to be having so much fun... It won't hurt to... masturbate a little~~"

You finger yourself fantasizing about whatever sex they're having next door, and cum all over your bed sheets before going back to sleep.

By the morning, the sounds have stopped.
