Conor groaned as gallons of cum oozed out of Marcus and on to his chest. Of course, the growth spell, Conor chanted and added a proportionality spell, so that Marcus the penis and Yoshua the balls would always be proportional to him, along with his clothing. He chuckled as he began to grow to fill the room. Marcus and Yoshua's furniture were crushed like matchsticks under the giant's bulk. Then Conor transported himself outside using a teleportation spell.
Yoshua groaned as the giant stepped over some mountains, and sat down in a valley to jack off.
"I bet you were feeling neglected, Yoshi," Conor says fondling his giant ballsac with a giant hand.
NO, NO, No, no, oh, YES! screamed Yoshua's and Marcus' minds as they exploded 140 gallons of cum on to the giant's massive abs.
The room mates were too exhausted to resist and Conor cast a spell to make him normal sized again. He teleported back to his own rooms.
Conor wiped himself off, and pulled on some boxers. "Hehe, you guys should thank me you're going to be room mates for a long time."
Marcus and Yoshua shrank into each other. Flesh pressing against flesh, the two slept in the darkness of Conor's zipped trousers.
