Ken and you have been best friends when both of you were still learning how to talk—You both are inseparable despite both of you being polar opposites. You were an extrovert and outgoing while he was an introvert and nonchalant. After you both entered college, you decided to live together so now, you've been roommates for more than 5 years.

Despite Ken's quiet personality, he sure goes to the gym a lot to unwind and it catches your interest but you've fairly gotten used to it. The thing you've noticed the most was his unrealistically big chest, it was practically the same as a woman now, bouncing when he ran, it was distracting, really...And quite tempting.

He was sitting on the couch, watching TV like he does everyday and a risky idea came to mind. You got out of your room and sat down beside him asking if you could touch his chest. Ken was confused at first but shrugged it off instead and agreed since it was you.

"Sure."

Ken turns his body around, displaying himself to you since it was just normal bros stuff, right?
