“We really going through with this,” I asked Sherel as we both peeked out the window of the small house we leased. There were four of us roommates here, all college students and all psych majors, five if you counted the pet, but we usually didn’t; we considered ourselves sisters of a sort. “It was your idea, Mandy,” she replied with a condescending look, “Unless you got money from some fucking job, we need this gig.”

“Gig? Is that what it is,” I muttered as my heart raced at the approach of a car coming up our driveway. “That’s got to be him!” I hissed in warning as we both prepared ourselves for this visiting stranger, while we looked in unison at the small closet door jammed under the stairs. We sometimes jokingly called this closet the Harry Potter room, like in the movies, but not today. Today was serious.

“Were’s the lab report?” Sherel asked excitedly as someone knocked on the door.

“It’s right there on the chair,” I told her as I opened the door carefully, revealing a tall man wearing a baseball cap, who I guessed was just under thirty. “Ted?” I asked as I did my best to see past him in case someone else was lurking out there. Us girls couldn’t be too careful in this situation, particularly since none of us had ever done anything remotely like this. Well, we had enslaved, I reminded myself but never sold.

“You Sherel?” he asked in a gruff voice, setting off my lesbian sensitivities immediately. Fucking men and their low voices! Gave them advantage on everything, well over women anyway. “No, she’s Sherel,” I told him as I opened the door to let him in, a little surprised to see how large the duffel bag he was carrying was. I could see my other three roommates hovering secretly in the background, looking as jitterily as I felt now.

“Here’s the labs,” Sherel said as she handed over a stapled set of papers which detailed the health state of a girl we were about to introduce him to. “Mine,” said Ted as he handed us a similar lab report. It read, “Theodore” as the first name, but the last name was blacked out.

“Is it close enough?” I whispered to Sherel for fear the STD report might have been for someone else. We wanted our little bitch back in good health after the lease period.

“Umm ... can you show us a driver’s license or something ... you can hold your thumb over the last name ... and address...” Sherel said with her best stern lesbian face on. The guy nodded his head in agreement and then proved to use by the photo and the first name that he was likely who he said he was. It was a good move on Sherel’s part, I felt. Still, like every girl here, I had reservation about selling our pet to a man. We’d all voted for this in the end. We really needed the money.

“Seven thousand,” Sherel said as Ted put his driver’s license away. From the duffle bag he pulled out a thick manilla envelope and gave us a short look inside. It was stuffed with one-hundred-dollar bills.

“Let’s see the merchandise,” Ted demanded with grin.

“Fuck,” I muttered under my breath when I saw the disapproving look on Sherel’s face. She hated men like him with a passion and could sink this deal on a whim I knew. I unlatched the small door under the stairs, finding a wide-eyed pet staring back at me with a frightened look on her face. “Don’t speak, understand!” I said forcefully, getting a quick nod in return. For over two years we’d kept this bitch isolated, training her to please us sexually by any means possible. She’d originally volunteered for this psych experiment, but I’m guessing didn’t understand how we’d become so bold and domineering as to sell her on a whim.

“She goes by Pet,” I said as I pulled her out by the chain attached to her collar. I really didn’t know what else to say to this guy. He had money, and we had need. College fees had gone up along with the rent, so here we were. It had never been the plan to whore her out, just to subjugate her mentally as far as we could. She’d consented to the experiment, at least originally.

“She’ll do,” the guy said as he reached out to brush Pets long black hair out of her eyes.

“Ok!” Sherel injected firmly, “We want two thousand at the end of each month, like we agreed. And she has to be back here physically by September first ... when the next semester starts.”

“Got it,” Ted said softly as he used the leash to force Pet to do a three-sixty. He made no effort to hide the leer on his face.

“What about the other stuff?” I reminded Sherel.

“Like what?” Sherel asked as she watched Ted lift the short crop-top our pet was wearing, exposing her boobs which had heavily pierced nipples.

“Piercing and bruising ... things like that,” I hissed at Sherel.

“Umm,” Sherel shrugged as she watched Ted run his hands over Pet’s naked ass, which was easily done as Pet only wore leggings that run up to her upper thighs, leaving her bald mound fully exposed.

“Umm,” Pet groaned softly in complaint as Ted ran his finger over the piercings through her pussy lips. As a group we were proud of the body piercings we’d put on our pet.

“Three on each side, nice!” Ted said as he started thumbing the one through her clit, causing Pet to lean forward a bit with a surprised look on her face. “She’s thin like you said,” he nodded in satisfaction.

“We keep her under a hundred,” Sherel informed him, “she’s weighs ninety-five ... ninety-six maybe...”

“You can keep her that weight?” I dared to ask, “She doesn’t have stretchmarks or anything ... wouldn’t want her to be thinner.”

“I can handle that,” he said, “She got a tight pussy?”

“She’s the dildo queen!” Sherel smirked in reply as if bragging. “I’ve had two hands in that cunt ... think I told you that.” Pet closed her eyes as he inserted a couple finger into her pussy, clearly, she was wet already. Had to add this fact to my coming Ph.D. thesis on this experiment, I told myself. Humiliation and arousal would be the chapter.

“She free to leave,” he asked next as he unclipped the leash from her collar and took a step back as if testing this fact. Pet made no move to flee.

“Physically yes ... mentally no,” Sherel chuckled, “Pretty sure she’d stay where told, even if the house was on fire. Don’t you think Mandy?”

“Ah ... I really don’t want to find out,” I replied, “ ... but probably ... we’ve disciplined her enough times ... cruelly a little ... lot of hypnosis. Guess her mind is subordinate to about everything external ... at least for now.”

“She means we’ve choked her out on occasion—go ahead!” Sherel dared him with a sneer. I shook my head slightly at Sherel’s behavior, thinking it totally unnecessary as the deal looked sealed to me. When Ted expertly slipped a hand up under Pet’s chin and began to squeeze, a thrill ran through me. Seconds passed as Pet’s face turned red, still Ted wouldn’t relent. Pet finally began defending herself by pulling on his arm, but that earned her a sharp rebuke from Sherel who looked to be fascinated by this foreplay.

“Behave, Pet!” Sherel snapped, getting an immediate response from Pet, who quickly lowered her arms as her face became ever redder.

“Whoa!” I called out as Pet’s knees started to wobble, helping now to keep her from hitting her head if she fainted. She nearly did, but the three of us caught her, just before her knees would have hit the floor. Ted released her throat, allowing us to keep her on her feet as she blinked in confusion. Another entry for the same chapter I promised myself. I desired more from him now!

“You can scrag her now if you want ... test drive ... Andie’s boyfriend rides her like a bicycle sometimes,” Sherel told him, obviously as turned on as I was at these tests. Andie’s name was really Amy, and she was bisexual; a fact we hadn’t known when we excepted her as a roommate but decided to let it pass once we did learn. Sherel never let Andie forget the transgression.

“Put your hands on the wall—feet back!” Ted ordered as he forced her a little to comply by kicking her ankles further apart. ZIP! Out came his dick through his fly, and a moment later he was in our little Pet’s twat. I watched Sherel carefully to confirm she wasn’t going to freak out at this blatant fuck. She hated men and the sight of cock, but I saw nothing but amusement on her face now.

“Uggh, uggh, uggh,” Pet groaned as she was fucked hard by this stranger, who now had a tight grip on hair.

“You going to cum in her?” Sherel practically panted after nearly a minute of silently watching in awe.

“Yeah, she’s not on birth control,” I warned, “We ... we never needed it much. Right Sherel—Andie’s boyfriend always used a condemn?”

“Not our call,” Sherel said with a flushed look to her face, dismissing my worries completely.

“Ahhh ... ahhh ... ahhh,” he growled as he fucked then suddenly pulled out of her pussy and demanded she blow him. Pet did without hesitation, though a little robotically, I thought. I wondered now if that was an unwanted side effect of our training as showing enthusiasm would have been better, though this was pretty hot to watch all the same. We’d created a complacent slave for sure!

“I don’t want to see any cum drip on the floor!” Sherel growled down at Pet, “I’ll fucking whip you in front of him!”

“Accckk ... accckkk ... mmphhh!” Pet choked around his cock, making me think she would fail at her next task when it came time to swallow.
