Family Ties/Since she's being so accommodating, demand a threesome with your daughter.
"I'll fuck you senseless, but only if you do something for me."
Stacy has pressed herself against your torso, clawing at you desperately. "Yes! What?! Anything!"
"I want you to seduce our daughter into a threesome with us."
You can't keep yourself from grinning. She already offered up your daughters as compensation for her interest in Timmy. But you're curious if she'll follow through with it.
"Oh. As in right now?"
You almost tauntingly kiss your wife's lips before nodding slowly. "Yes. Right now."
Stacy has to bite her lip to keep it from quivering. With only a brief pause of contemplation, she snatches her blouse from the floor and slips her way past you. She's already at the stairs, hastily pulling on her top, before she stops herself.
"Wait... did you mean Heather, or... Jessie?"
