Looking over the shelf you couldn’t help but focus back on the Cum Production cylinder vial, the thought of it too tempting.
You picked it up and studied the label.
CUM PRODUCTION - M - 5ml
CAUTION: DO NOT DRINK. APPLY DIRECT TO GENITALIA.
The pale gloop inside pressed itself against the warmth of your hand outside the glass. Maybe it wouldn’t hurt to see what would happen ...
—————
You carefully looked around for signs of Nullos before taking your place before the shelf. In one hand, the vial of Cum Production essence. The other, fishing out your own cock and balls through the hole in your boxers. There was nothing wrong with what you had, but the idea of doubling how many loads you shoot … well, you’d be like a real pornstar!
Twisting off the seal, you held the open end toward the tip of your dick and watched as the essence inside was tipped toward it’s entrance. As it touched your warmth you saw it perk up and start to move faster to pool around your dick head, almost as if it was excited to find a body again ...
Then it started to push in. You bit your lip and started breathing raggedly as the slimy pearl liquid streamed down inside your member rapidly, bulging out the length and sending a chill down your crotch. As the last of it flowed into you you felt it spreading past the base of your crotch before the cold began to pool in both your balls and your prostate making them quiver and swell.
You felt unusually full as the chill subsided. You were now producing the same amount of cum as two grown men!
