They both work together to get their prize

For five minutes they switched my cock back and forth. Using each others spit to lubricate my member.

And then their were two mouth on my cock, working back in forth together. and I was too far.

There were moments when they both would be at my cockhead, and they would share a kiss before continuing to suck. And sometimes both of their tongue would work together on opposite sides of my cock.

And both of their asses, covered with sweat giving me an amazing view.

It was too much, and when my dick first twitched Sasuki knew what to do.

Her lips wrapped around my cock. My cock almost was in pain as I sprayed shot after shot of cum into Sasuki's throat.

"Damn it," said Tenten," we both worked for that."

Sasuki said nothing as it collected in her mouth. When I was spent, she stroked me a few more times and got out the last drops into her mouth. When her lips left my cock she looked at my sister, and Tenten suddenly understood.

Their lips connected in a clumsy kiss that allowed cum to pour down their chins. Sasuki's tongue flew into Tenten's willing mouth, and quickly the cum was traded back and forth.

"Oh fuck," I said.

Suddenly, their eyes grew wide, and both looked to me.

With an audible gulp Sasuki swallowed all the cum that was in her mouth.

Tenten looking at me not knowing what to do.

It was then we heard a very frightening noise.

KNOCK KNOCK KNOCK

Our eyes grew the size of saucers. The girls were frozen in place. It was up to me to do something.
