Finally, Mother announced it was time for her to go, and the girls all said goodbye. That was usually Sam's cue to start flirting with me, perhaps playing footsie under the table or otherwise making some double-entendre designed to put us both in the right mood for her regular Sunday afternoon shagging. But today she didn't, and the girls kept right on going.

It was Mari who stopped the conversation and realized aloud,

“Waitaminute, you two haven't fucked Matty yet! You left the room yesterday morning while the rest of us were fooling around with him."

Sam and Belle exchanged a glance, and Sam explained, "We had some stuff to work out with each other." Her gaze was a little hard, an expression that clearly told Mari to ‘drop it'.

But Mari waved her off with a waggling hand.

“Not what I was getting at. What I MEANT is that you two are long overdue. And... all sweaty from the run and everything, you two should totally go take a shower with him."

Belle grinned, but Sam frowned. "But he's your boyfriend this week."

Mari shrugged.

“It means I'm his primary, but it also means I can share him if I want. And I want."

“You sure?" Sam asked a little uncertainly, although there was no mistaking the arousal in her eyes or the way she'd started squirming in her seat.

Sam looked alarmed and exchanged another glance with Belle. "Ummm... what?"

Mari grinned.

“I think I like being Matty's girlfriend.”

The other girls both laughed. Belle was now visibly squirming in her seat. "So that's a yes, right? We can fuck him?"

Mari beamed at her bestie.

“I'm gonna enjoy this for now, but I can't believe you even think you have to ask. Once Team Belle, always Team

Belle." Mari even pumped her right fist into the air.

Belle couldn't shove her chair back fast enough, racing around to grab my hand and start tugging me up to my feet. Sam also got up, but was rather more casual about it. Mari, however, didn't get up right away, and Sam frowned.

“Aren't you coming?"

Mari waved her off with a waggling hand.

“Oh, I'LL come up to watch once you guys get started. But I really want him to focus on the two of you. It's like Neevie said yesterday: ‘All for one, and one for all.'"

Sam grinned and patted Mari's shoulder, saying sincerely, "Thank you."

Belle had already dragged me halfway down the hall. "C'mon, Sam. Let's
