As Coal's orgasm faded his cock became limp and laded between his legs onto the floor. It was still huge even know it was not at full erection and now measured a foot and a half long. Coal just sat there looking down at his huge cock when all of a sudden it began to grow bigger and bigger. His cock expanded until it came to a stop half way across the dorm room.
"Xan why his my dick still growing?" said Coal in a panic. "The demon seeds are making it grow so big" said Xan. "How do I make it stop?' asked Coal
Just before he was about to answer him there was a knock at the door. Then the door few open and standing there was fellow dormy from down the hall. It was 18 year old Justin. Just as he walked into the room Coal's cock began to grow again. Justin and Coal watched as Coal's cock grew until it reached the open doorway. It then stopped growing ad blocked the only way out of the room. Justin then looked at Coal and said "How did you make your cock so big" Coa replyed "I drank some demon seed and it began to grow and I don't know how to stop it from growing."
Coal then felt that he was going to cum any minute and he did. The cum shot out, flooded the hallway, and went into each dorm room.
