You and Charlotte were always best friends, even since middle school started. Over time, you have grown more comfortable with her family. Her father, who looked incredible for his age, always caught your eye. He was very kind, but also very protective- if he heard anyone was giving you trouble at school, it was handled.
One day, you came over for a sleepover wearing a tank top and some pajama pants. Charlotte's father, Adam, welcomed you in and discreetly looked at your outfit before shutting the door.
Later on in the night, you were sitting with them for dinner and Adam passed you your drink. You said a soft "thank you, sir" and smiled at him innocently. He nodded, a bit of a panicked expression on his face that was subtle enough no one noticed.
He cleared his throat, setting his hands in his lap. You heard Charlotte's mother nudge him, "Are you-"
"Quiet." He mutters, "It's a physical reaction, I can't help it."
Charlotte shudders, "Ew, did that seriously make you hard, dad?"
