After watching the whole ordeal Trish finally spoke "I'm sure Tanya can... Orally prove she's paid for it. After all, we wouldn't want to waste money when we don't have to. Tanya, give this nice man a blow job."

Tanya started to kneel before Trish interrupted, "Wait."

"Thank god!" Tanya thought only to have her relief turned to dismay.

"We wouldn't want to get anything on that nice new outfit, take it off first. Although, you can leave the boots and gloves on."

Tanya immediately pulled off her top before shimmying out of her skirt and once again kneeling in front of the clerk. This time nothing stopped her. She unzipped his pants and immediately started sucking his erect phallus. The clerk thrust over and over into her mouth until finally grabbing the back of her head he blew his load into the back of her throat. Gagging for a moment, she finally pulled her head away, eyes searching for a place to spit before Trish once again interrupted her saying, "Swallow it!" at which point she unhappily did.

"Come back soon!" The clerk added, smiling at Tanya as she stood with nothing covered but her hands and feet.

Trish looked at her with a devilish grin.
