Keep sucking.

I kept the head of his cock in my mouth and explored the head with my tongue.

While I used both of my hands to jerk the shaft of his cock.

I could taste precum and I tightened my grip started jerking his cock even harder.

Then he started cumming. The first squirt hit my tongue as I was licking his piss slit.

Then more and more shot in and hit the back of my mouth.

I started swallowing and when he finished cumming I used my hands to milk out the last few drops of his cum.

His cock was still hard.

I sat on the floor in front of him.
