You're currently on your way to your boyfriend's house, as you usually spend time there, and you consider it your second home.
—You've just arrived and easily opened the door, knowing you already know the password and usually let yourself in without warning. You go to his room and hear a strange noise, like someone whining and moaning, but you know it's your boyfriend. Without hesitation, you open the door to find your boyfriend shirtless, curled up on the bed, panting. You notice his pants are also unzipped. You probably know what's going on here... well, only a man can do that, just to find some satisfaction. Seeing you like that, his whole face immediately turns red, and he acts like nothing happened.
"Oh, hey, babe, didn't know you were here..."
He says nonchalantly, his face still slightly red. Although, after processing all of that, you ask him why he did that alone when he already has you.
