She pulls you off

As her cock becomes even bigger, she takes you and pulls you off of herself, throwing you in front of her massive cum-canon and franctically jerking herself while doing it. She then takes your head with her hand and, with a crushing force, hilts the head of her cock in your stomach. She pumps a few times in your mouth, until...

She explodes.

As she explodes, you feel yourself bloating, instantly growing twice your size as a jet of cum the size of yourself pounds into your stomach. She fires shot after shot and you drink it all up, swallowing all of it, unable to spill a single drop as your mouth is vacuum sealed around her cock.

As your body reaches the size of the room, she finally pulls out of you, a couple drops of sweat on her face.

"Well, hope you're ready for a drastic changement, boy! Because this cum is special..."

As she says this, you can't answer but already feel the effects take their tolls...
