To his home

The car stood in the driveway of a nice suburban home. From the bell sign i could easily guess that we were at Zack's home. Ashley opened the door and as soon as she was outside the car she got on all fours and obediently waited for instructions. Zack fixated me in the backmirror of the car.
"Simple rule: female bitches on the premises are to crawl on all fours. Now get out and follow me, if you'd be so kind, Miss Stone."

The way he pronounced my name left no room interpretation, i wasn't his homeroom teacher anymore but rather i'd be his painslut for as long as he saw fit. I got out and on all fours, as soon as my hands touched the ground Ashley pressed her wet pussy in my face and i started eating her out, tasting a mix of cum and piss from her, until Zack stood next to us. He grabbed Ashleys hair and pulled her forward, grunting to me to follow before he took both of us to the backyard.

The grass was evenly trimmed, most likely by a mower drone and a table with some chairs was set up under a parasol. The door to the kitchen was open and the wet sounds of someone getting pounded were clearly audible from inside. The gate in the fence to the next property was open, suggesting that the neighbour was spending some time inside Zacks' mom. He seemed unfazed by that and grabbed a garden hose before roughly cleaning first Ashley and then me with it.

Afterwards he gestured us inside, we entered through the kitchen door. The place looked tidy and clean, disregarding Zacks' mom getting railed by a man on the kitchen counter. From the looks of it she had been preparing dinner prior to her current engagement. Bits of chopped vegetables were laying everywhere and her ass had been stuffed with carrots, giving her an obscene green tail. The man that pumped into her cunt looked over and greeted Zack.
"Hi there sport. School already over? Nice fresh meat you brought in. Can i take a pounding at that later, maybe over dinner? She looks delicious." He leaned down, stopping his **** on the womans private parts to feel up my body and casually grabbed a fistful of my tit, squeezing it tightly, the pain forcing a wave of pleasure troughout my body that made me squeal involuntarily. He grinned but Zack denied his request.

"Sorry. I brought that home for a very specific task at hand. But i'll send Ashley down as soon as i don't need her anymore." His sister took that as a promt to move into the corridor and up the stairs, before i roughly got pulled the same way. While we were ascending the stairs, Zack on two legs like a human being while i crawled in front of him like a house pet he leaned forward, telling me: "You know, my sister might be just another freeuse fuckslut, but my dad made sure what came from my mom's womb was just the best quality offspring. She's not only hot, hyper fertile and obedient, she is also incredibly smart. I am really lucky i get so much use out of her since my dad has a whole staff full of qualified girls around him, tailored to his needs. I hope i get the same benefits for you after i breed you today. So that was his angle. I was sure at thsi point that i wasn't the only teacher of his that he had taken home and knocked up, the sly devil had a whole system to it, it seemed.

I was at the last steps when my body heated up, i could feel the effect of hormonal flood as i got aroused beyond anything i had felt in a while. My pussy geban dripping, leaving a trail of fluids down the hallway and my body were shaking as we entered Zacks' room. Ashley knelt in front of a laptop, setting up a software before she put it on a nearby desk and looked at Zack. "Her inhibitor is disabled, she's ovulating for the next 60 minutes as usual. I set everything to max values, no way she's not conceiving." She gave a look that was equal parts curiosity and pride before she crawled out of the room.

I already had trouble focusing on anything while Zack dropped his bag in the corner of the room and sat on the bed, beconing me over. I crawled towards him and kneeled in front of him, panting, my body shivering in anticipation of what's to come.
