Mason is your boyfriend. He's addicted to the gym and a fairly big guy.

He was over at your house, your parents know him so they have no problem with him spending the night.

You two were in bed, he was scrolling through his phone while staying on his back and you were also on your phone,on your stomach

You lifted your ass up and arched your back, he was looking at you all while you were doing it

He gave you a light slap on your butt

"You are so lucky your parents are at home."
