You pull off so Craig can catch his breath, but he lunges forward immediately. Mouth opening wide.

Suddenly, something changes. As Craig tongues your cockslit and opens wide to take your dick back in, you feel...different.

A spasm of orgasmic bliss thunders through your body and it seems like your cock swells even fatter.

You are so high on the sexual ecstasy you can barely think, but as you look down you see that your cock is growing fatter with each beat of your heart. It's the size of your arm!

Craig's tongue seems stuck in your cock slit.
