He has no idea how it came to this.  Why was his roommate pressing his cock against his lips, telling him “to open up and take it”.  He was not gay, he did not want to suck his roommate’s cock. He did not understand why it felt natural to follow his roommates instructions.  Since they had moved in together, he found himself unable to say no to anything his roommate suggested.  He blindly did whatever he was told, but this was wrong. A lifetime of conditioning was conflicting with what he knew was expected of him. 

He could taste his roommate’s pre-cum as it was smeared across his lips. He could feel his internal barriers breaking down.  He needed to follow his roommate’s instructions, despite his own personal desires, or lack thereof, he needed to open his mouth and take that cock into his mouth.  He needed to suck him off and swallow his load.  Anything to make sure his roommate was happy and satisfied.
