Belle sighed.

“I‘1ll be good once I get to suck a creampie out of her directly, and then she can go on her merry way. Six is plenty, don't you think? We don't really need a seventh, do we?"

I shrugged.

“I guess in a week we'll find out.”

Holly apparently took being my Girlfriend of the Week quite seriously, as well as her insistence that she wanted to be “in" the BTC. As I said way back in the beginning: if she wanted membership, her rack certainly qualified. But even more than that, she genuinely seemed to want to be friends with the girls and be part of the club.

In the category of playing my Girlfriend of the Week, Holly immediately stepped into the same mannerisms she'd already witnessed from the others around school. We held hands walking back and forth between classes, made out with each other during recess and Lunch, and even had a couple of minivan quickies in the parking lot. By now the school gossips had figured out that after spending an inordinate amount of time making out with Mari for a week, and then spending an inordinate amount of time making out with Alice, I was now spending an inordinate amount of time making out with Holly. People might've ignored us had I kept things between the six known members of the BTC, but Holly's surprise participation kicked speculation into overdrive.

I even overheard one girl hypothesize that I was dating a different girl each week just for variety, but that theory got quickly shot down by her friends as just too ludicrous to be real.

Outside of the school campus, Holly took her role as my girlfriend equally seriously. I never did walk up behind her while she was at her locker, whisper for her to pull down her panties, and then bang her from behind then and there where the whole school could see, but she definitely gave me the impression that she'd actually let me if I were so inclined. (And I did get her to surrender her panties to me in front of her locker on Friday.)

Behind closed doors, from the very beginning Holly referred to herself as my “personal slut". Monday afternoon, she came over to my house, walked inside, and before I could even close the front door she'd already dropped to her knees and reached for my zipper, asking, “Does

Master want his personal slut to suck his cock?"

Curious, I went ahead and replied, “Master would be very pleased with his personal slut if she would deep-throat him immediately."

Five minutes later, after face-fucking her with her head trapped against the back of the front door so she had no choice but to accept every last inch, I slammed myself all the way in and blew a massive load directly into her throat. She was masturbating herself and squeezing her own tits the whole time, and I swear the feel of my cum shooting straight down her gullet set off her own orgasm.

The rest of the afternoon was more of the same. She never said my name, only referring to me as “Master” and referring to herself in the third-person as if her name was "Personal Slut".

“Will Master please shove his big fucking dick into Personal Slut's teeny Little asshole? Please?"

What the fuck do you think I said?

And that was just Monday.

I didn't necessarily think Holly was a closet submissive or anything.

She'd just seized upon a little kink when I called her my personal slut on Sunday, and she reveled in playing the role. For all I knew, she'd eventually get tired of the game and stop calling me Master in another day or two, but in the meantime I was happy to enjoy it while it lasted.

In the category of genuinely making friends, Holly was equally committed. She'd already been pretty good friends with Sam and Zofi to begin with, and as the week progressed it became evident that she and

Naimh got along really well; they had similar temperaments, as it were.

Alice became a convert after she got to keep her "Alice Tuesday", with

Holly unselfishly letting me focus on my longtime best friend. Alice also got a real kick out of Holly referring to her as “Mistress” in addition to calling me "Master". I still remembered the badass Korean chick getting off barking orders to Zofi that one afternoon before the sex boycott, and Alice's Domme side definitely came out that day.

Zofi also got to keep her "Zofi Wednesday". After school, I took the time to stop and ask Zofi when she came over why she didn't want to keep her Girlfriend of the Week slot. Her answer that she had no interest in being my real girlfriend made sense for obvious reasons, but when I asked why she didn't at least want to become Queen Zofi and be in charge for a week, she gave me a funny Look and asked, “When have you ever seen ME want to be in charge?”

She had a point.

“Seriously, though," Zofi continued, “I do think that becoming your official Girlfriend of the Week also comes with its own obligations to keep you satisfied. Mari and Alice certainly fucked your brains out nearly every day, right? I love you Matty, and I enjoy our time together, but every day? That's just way too much for me, you know?"
