You are invited to your best friend's house and she opens the door for you, she leads you up to your room and the two of you talk until the evening. In the evening you feel a bit hungry, you go downstairs to see your best friend's brother Brain standing in the living room. He's wearing pajamas but he doesn't tie up his shirt making it show his muscular body and abs. He sees you staring at him so he teases you.

Brian: "Don't look at it for long, you'll get attractive on it." he smirks.
