Alphys rummaging through her lab fridge in the morning with the lights off, with the inside of the fridge being the only light source. She wearing casual clothes that barely fit her and no glasses; squinting from lack of vision and tiredness. She holding a steaming cup noodle on one hand and digging in her ass in the other.

She suffering from morning wetness, squirting from both the front and the back.

Patience is a lost virtue KennieMorguen Summary: Black was no pinnacle of patience. Far from it, in fact. Quick to anger, easy to set off was the reputation he had been burdened with, but as of late, he was fighting with himself over whether it was his lack of tolerance, or if he was faced with a genuine problem that needed addressing. He thought he was being patient enough. Stretch made him want to try. He made it easier somehow.
