Cover your ass.

"Shit..." you whisper. "Get back in the shower..."
Alli returns to finish her shower, and you head downstairs to see Riley, laying out some groceries on the kitchen counter. It looks like she went out to get stuff to make tacos.
"Riley, we just went shopping before you got home." You try to sound and act casual.
"You didn't get anything for tacos, and Alli wanted tacos." She turns and smiles, walking towards you and putting a hand on your chest. "Do you want some tacos, too...daddy?" She takes your hand with her other one, moving it to her crotch.
"Riley..." you start to admonish her, but she stops on her own when she hears the car doors close. Jenna and Karen are home.
"Hey baby...hey honey." Jenna greets you both from the door. She gives you a kiss on the cheek while Riley does her best innocent face.
"Who's in our shower?" Jenna asks once she hears the water.
"It's probably Alli." Riley says. "She got a little sandy at the beach this morning." Not that you could see, you think.

The rest of the afternoon passes without incident. Jack comes home around 3:00, and heads up to take a nap before dinner. You made reservations at Chat Noir this morning, setting them for 6:45 PM, so at 5:30, you shave, get dressed in a nice pair of slacks, and a deep blue shortsleeve button up shirt. Jenna brushes out her hair and puts on makeup, wearing sheer knee high stockings under a tight dress, with a garter thong and no bra as far as you can tell. Your mouth waters as you watch her dress, and she winks at you as she clasps her nylons.

You head downstairs where Jack and Karen are waiting. The smell of tacos lingers in the air, and the girls are eating by the poolside. Zoe's with them: she came home from the tattoo parlor around 5:00 PM. Karen's wearing almost the exact same outfit as Jenna, though she's clearly wearing a bustier under her dress.

"You guys ready?"
"Abso-fucking-lutely, Jameson!" Karen pronounces with gusto. Jack looks a little sleepy. Probably still whipped from his encounter today.
Jenna comes down, and the four of you head out, taking an Uber so that you don't have to worry about driving home.
