Only if Enid is in the middle.

"On one condition," Morticia says.
"What's that," Enid asks.
"This threesome is just both of us using you."

Enid blushes at the thought.
She nods nervously.

Jack takes a seat as he watches Wednesday strip down while Morticia leads Enid back to the couch.
She slides off her panties and tosses them aside.

Enid starts to go down on Ms. Addams as Wednesday is now in her underwear.
She goes to a nearby drawer and presents something to Jack.

A Strap On Cock.

She slides her panties off and slides into the harness.
She tightens it and then smirks at Jack.

Wednesday is nice enough to lube it down as well, which is good for what she's about to do.

She goes behind Enid, who is just lapping away.
She rubs the rubber phallus against her pussy, pulling her panties aside.

Morticia pushes her face back down as she goes to look.

"This is what good girls like," Wednesday says, rubbing against Enid's pussy, "But you're a bad girl."

She aims the rubber cock at the blond's asshole and makes entry!

"Take it," she says, pressing Enid's face down this time and fucking her.

Jack loves the Show.

Deep down though, he wonders if he's only there as a participant.
