I wonder how long it takes until she guesses the safeword

You continue to listen from around the corner. After a while it sounds like Evellyn manages to wrestle the gag free, but that does not mean her troubles are at an end.

“Ouch! Polly why are you…”
>smack!<
“I order you to ceas-“

“Ow! Ow! Ow! Uhm, ‘breakfast!’”
>slap!!<
“‘Snow!’ ‘Sword!’”
>smack!!<
“‘Orange!!’” (That one was very close)
>spank!!<
“‘Stop this at once Polly!! ‘Painting?!’”
-“You were closer before, milady,” Polly replies, before continuing the rhythm of spanking.

In the end, rather than guessing the correct fruit, Evellyn appears to only find relief when the other condition on the card is fulfilled, and you peek around the corner to see the maid undo the knight’s restraints while being chastised by a painfully red-buttocked Evellyn.

“What by the goddess made you think I wanted to get spanked?! Where did you get such a firm paddling hand anyway?” Evellyn mutters while rubbing her sore ass.

“From the card, mistress; It’s just that I’ve always been taught not to question my betters,” Polly apologetically offers.

“What ca-“ Evellyn stops as she notices the tag on the floor, and after quickly scanning through it she gnashes her teeth, tears the paper into a hundred pieces, and orders the maid to prepare her a bath before storming inside.
