You start with the change rooms.

You decide to check the nearest change room first, opening the door carefully and listening, but hearing no sounds of any kind, let alone a happily rutting couple. You walk along the corridor, quietly opening doors at random but hearing and seeing nothing.

You frown in puzzlement. From the sounds of their conversation neither Millie nor Mr. Carrollton seemed like they would be likely delay finding a spot for their tryst, but you're beginning to wonder what has happened to them.

You open the door of one of the small gyms, finding it in darkness and hearing nothing. You're about to close the door and leave when you notice light seeping around the outline of a door on the far side of the room. You cross the gym and listen at the door, smiling as you hear the unmistakeable sounds of fucking on the other side. You turn the knob and slowly ease the door open, peeking through the gap.

Millie is bent over a pommel horse, her face an ecstatic mask of lewd pleasure, Tony Carrollton behind her pounding madly away at her shuddering body.

"Oh Yes! Harder! Give it to me harder! Fill my little pussy! Fill it!" she moans frantically, writhing on his cock.

"Take it! Take my cock! Who's your best fuck! Who fucks you hardest!"

"You do! Oh Yes You do! Give it to me! Give me every inch! I'm your schoolgirl slut! Your best slut! You fuck me so hard! Fill me up with meat!"

"You're so tight! So tight and hot! Oh Fuck I've missed this! Missed fucking your tight pussy!"

"Make me come! Make me come on your cock! I'll come so hard for you! Make me come!" she wails, grinding in ecstasy.
