Kinktober day 8 hanging around

Sophia, just finished her training session at home but her best friend and roommate Luna decided to play a little prank on her...

Tying her up and leaving her hanging for a while, later on Sophia's girlfriend, Alexa, decided to pay her a visit, Luna opened the door and after being asked if Sophia was home she said, "Sophia?, yeah she's okay she is just hanging around"

"Mmmmmphh!" Could be heard from the other room

Alexa decided to enter the house and go investigate the noise but from behind Luna with chloroform in hand grabbed Alexa from behind and covered her mouth making her slowly fall asleep.

Why does Luna have chloroform?, what kind of prank is this? and most importantly why is Luna doing this?

Unanswered questions that will most likely remain like that, but something is certain, this will be continued (I'll draw Alexa tied up, maybe in the next one? idk but I will make her appear in one kinktober drawing as a continuation of this little story I made up in 10 minutes)
