A little more potion

Tess walked away, proudly laughing. "We really make you that hard Gregg? Neither of us are even naked."

"I... I'm not enjoying this. It just... happened." He complained, taking a second to adjust himself and get his dick covered by his undergarb again.

The customer pouted, but Tess noticed something. A piece from the broken potion bottle! It still had some potion in it! "Well, naked or not, can I buy a tent from you? I'll tip extra for the little show you gave. Even if it's over now." The customer teased.

Tess bent down and picked up the potion. Carefully, she brought the piece over to Gregg. She grabbed his pants (which was hard since she couldn't see them), pulled them away from his body and dumped the potion on his undergarb.

It was only a few drops, so she was able to do this pretty stealthily. Gregg didn't even notice, since he was helping the guest!

Even for just a few drops, they began to make his undergarb entirely vanish!

As he helped the woman, he didn't realize that he had become entirely naked! His cock, now soft again, was back on display for the woman. As were his balls and large butt.

The woman snickered, but didn't want to ruin the fun this time. So she just accepted his help, only quietly stealing glances at his package.

Meanwhile, Tess was enjoying his rear.
