Harry inhaled more potion fumes

    by: Austinmclamegrowth Author IconMail Icon
Harry now examining Draco’s huge body, bigger than him thought he looked hot all confused and worried still looking at his hands in shock

“Are you enjoying it?” Harry said with a proud tone “I guess… I mean I won’t fit in any of my clothes anymore.” Draco said timidly Harry didn’t care if people saw him completely naked they should be happy they got the chance to see him like that

But Draco didn’t seem to like the idea that much “my clothes are so tight.” Draco complained so Harry walked up to him and started undoing Draco’s shirt his pecs bouncing out and his the rest of the shirt immediately rolled off his arms

“W-what are you doing!?” Draco said timidly not doing anything to stop it “helping you out.” Harry said slyly and he finished revealing Draco’s top half he couldn’t wait to see what was underneath his pants

Harry immediately undid the button of Draco’s pants and practically peeled them off Harry’s cock immediately went hard being held back by his pants at the sight of a massive dick in a jock strap

Draco only let out and embarrassed shutter but Harry couldn’t pay attention to anything other than Draco’s body Harry immediately started rubbing Draco’s pecs and running his fingers along Draco’s cavernous abs

“P-potter!” Draco said backing up accidentally tripping and falling making a huge thud but Harry only followed him now fully overtop of Draco

“You like this don’t you” Harry said in a confident tone only to have the caldron that was beside them minutes ago to be shoved into his mouth and have the contents emptied into his mouth only growing him bigger sending his clothes flying off of him

His pecs rested below his chin his 6 pack now and 8 pack and humming his cock was huge sticking out 19 feet in front of him and his arms were being pushed even further apart but all this muscle wouldn’t fit on his 8 foot self so he started getting taller first 10 feet then 12 feet and finally reaching a massive 15 feet barely touching the ceiling of the room
