Well, Quinn says hookah doesn't hit hard and if it's softer than bong indeed, the effects shouldn't last long. Maybe a few hours. But if it's in the morning, it's all the better.
Wait, wasn't Lily in her bikini? If you choose to hang out with Josy, she is there with that bikini at the pool, no? Not a full sleepover, but she let MC take a nap in her bed. That equates to a full package sleepover to me. Hell yeah.
The next time she visits my MC's room, she won't have any other option than sleeping there.
