Be truthful

You collapse back onto the couch, much to the gratitude of your weary legs.

"Now we can talk."

Her eyes light up.

"Sister Alanis, we can save him!"

"Hallelujah!" you hear the old ugly one call from the kitchen. She bustles back in with a cup of tea in one hand and a chocolate biscuit in the other. Now blood is returning to your brain you remember that you keep those biscuits hidden away in the back of your cupboard so you don't have to share them with guests. That old bitch must've gone through your kitchen pretty good. She looks at Sister Holly with disapproval.

"For heaven's sake, where's a towel?"

You gesture in the direction of the linen cupboard. Sister Holly arises and goes and gets a towel, coming back in while wiping herself off.

"Now are you ready to hear the good news?" asks Sister Alanis.

Wait, have you got one more chance to get out of this? Sure, you got a mighty fine blowjob and are now seriously satisfied, but giving the hag one of your choccie biccies was never part of the deal.
