Ungentlemanly...

You should probably warn her about what's coming, but as you open your mouth to tell her, she takes your cock all the way down, pressing her nose into your stomach and gagging loudly.
"Oh fuckkkkk....." you can't hold it: you cum hard. "Jesus..."
Allison coughs, pulling off your cock fast and spitting your load onto the floor. She wipes her mouth with the back of her hand and sits back, still coughing and with watering eyes.
"Jesus, Alli... I'm sorry." You grab some tissue and hand it to her, and she spits into it and then wipes her mouth. "You took me by surprise with that last move." You kneel down.
"It's..." another round of coughs rack her tiny body. "It's okay. I just... it went right into my throat."You take more tissues and wipe her cheeks and face, and clean up your cum from the floor.
"Well...it felt really good, for what it's worth, honey." You help her up.
"Do you...." Allison runs fingers across your chest. "Want to...."
The distant sound of the front door saves you from having to answer.
"Shit..." you whisper. "Get back in the shower..."
Alli returns to finish her shower, and you head downstairs to see Jenna and Karen. Your wife, and the mother of the girl who just blew you. You do your best not to look guilty.
"Who's in our shower?" Jenna asks once she hears the water.
"You know, I'm not 100% sure?" you bluff. "I was about to knock on the door and find out when you got home. I think it might by Allison. Zoe's car isn't here, and maybe Riley dropped her off for some reason."
Suiting your words, Riley pulls into the driveway a minute later. She alks in with some grocery bags: it looks like she and Allison are having tacos for dinner tonight.

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.
