The girls were making out.

My cock sprung to life at the sight of my wife and her best friend eating each other out in the 69 position. Sam and Emma were best friends since they were little girls and I suspected they had experimented with lesbianism as they grew up since there was never any awkwardness when they kissed during our orgies. They were not only sisters but lovers.

I had to fight my primal urge to join them, reminding my dick that I was going to fuck the two Asian girls all night.

The girls either didn't seem to notice me or didn't care I was in the room as they kept munching each other's twats as I sneaked over to the dresser to grab the camcorder and tripod. Before I left I decided to record a couple minutes of lesbian action.

Katsumi and Julia were waiting for me in the other bedroom. They were lying back with their hands between their outspread thighs, fingering themselves.

"Oh good, you're hard already!" the Japanese girl chirped.

I was tempted to pounce on them right there and then if I didn't need to set up the camera to record our fucking so I could view it later when I got home. I hurriedly set up the tripod and angled the camcorder.

"We need your big cock in our tiny pussies," the Chinese girl teased, sliding two fingers into her drenched snatch.

With that I pressed the record button.
