How does your first time in Stocks go?

You’re given the rules

Locked into the stocks and bent over at the waist, you can feel the evening air all over your body. A chill breeze gives you goosebumps across your skin. Beside you is Jessica, similarly locked up. She bites her lower lip and looks over at you, but before either of you can say anything your mistresses lock the padlocks keeping you in place and speak up.

“Ok holes, you’re gonna be here for 2 hours. Not that you have a choice, but your job is to make sure every futa, girl, or boy that passes by leaves satisfied. Even if they’re just passing by I want to hear you beg to suck them off until they cum, or let them **** your holes. Is that clear?”

“Yes mistress” you say in unison.

Confident that you’re properly secured, your mistresses leave you and go back to their dorm.

Several minutes go by until you see someone cutting across the park and you both perk up, eager to follow your mistresses orders.
