How to play

Some time later, after the automated cleaning system takes the brunt of the work, you finish mopping up the last spots of Brittany’s ‘accident’. Brittany emerges from her bedroom, peaking around the corner, a remorseful pout poised her face, “I’m sorry…. I just got a little a carried away…”. Her tone was sincere, her post nut clarity showing her how difficult she could potentially make things for her brother.

“It’s okay Brittany. It actually didn’t take that long to clean up. These Clankers did most of the hard part for me”. Brittany perks up, her usual big smile returning as she strutted around the corner in her heels. She wore no bottoms whatsoever, and her thighs jiggled ever so slightly as she walked. Her cock was flaccid but her nuts were still noticeably swollen and making just enough cum for her flaccid cock to leave a leaky trail around the house. She wore a fishnet laced bralette, but it barely served its function. Her nipples were caught in the knitted fabric, and the rest of her smooth tan breast bounced and undulated with her every step. Brittany giggled and held her tits up before embracing you into a big hug, her tits spreading across your head. You sink deep into her soft pillowy cleavage, her natural post nut pheromones coating your hair and face.

“Thank you Bookie, I’ll make it up to you any way you want me too. Just tell me how you want it baby, and I’ll give it all to you”. Brittany’s cock twitch and flexed against your leg. You can feel its cum leak down your leg as her balls slowly inflated, still warm to the touch.

“Perhaps next time, you could just use some of the equipment. I mean, that is what they’re there for”, you hug Brittany back, your hand squeezing into her incredibly soft ass. “If it’s in the house, you can cum only with the equipment here. If we are in public I ask you try not to cum everywhere, and if you can’t help it, then please just have a condom on. Those are the rules from the hospital”. Brittany’s tits begin swelling around your head, you can feel their weight on your shoulders as they fatten with milk. Brittany moans softly in your ear before you break away moving closer to a strange tool just off into the corner of the room, “one more thing. You can’t lose control. If you ever feel like you’re getting to that point, you can use and do whatever it takes to avoid that, like this thingy here. This looks fun right?”

“That’s my breeding mount!”, she says jumping to the end of the equipment.

“Breeding mount? Like for horses?”, you say as she examines the fleshy orifice at the tip of the mount.

“Yes! I can use it to empty out my balls if they still have too much cum in them. I don’t mind leaving a little trail where I go, but sometimes they get a little too swollen and then I can’t get around”. Brittany spits on her hand and starts jerking off, her massive cock growing to full size right before your eyes. “Mmm, fuck, I haven’t used one of these in so long. I think I might need to empty the big boy tank”, she says whilst spreading her legs and aiming for the fleshy hole. Brittany’s swollen pumped pussy, releases a stream of cream onto the floor as she begins to slide into the breeding mount. The smell of a hyper in heat hits you like a wave.

“Hey, I don’t care when or how often you use this thing, as long as you replace the condom after your finished”. You head towards the bathroom only to be startled by how aggressively Brittany began to fuck the shit out of the breeding mount. You’ve never seen this side of her before. Her happy, ditzy valley girl persona was completely gone as she jack hammered this breeding mount. Grunting, and panting like an animal, Brittany slammed her pelvis into this breeding mount repeatedly, the sound of squelching lube and precum pumping into the condom at the other end of the mount. You advert your eyes, as Brittany grunts and groans, “And at least, try not to make too much noise at night. I still have to go to work In the morning”.

She doesn’t acknowledge you, only quickens her pace as her balls visibly swell to the size of pineapples. Her thighs shake as her ass and legs gain mass and weight. Her belly grows, pushing her tits aside as they spray multiple streams of milk in every direction. Her ass continues to grow, glimpses of her thick pussy flashing between her thrust into the poor breeding mount. Slapping against the mount, Brittany’s nuts tighten up, as her eyes roll from the mind numbing pleasure. “Oh fuck, it’s shoooo tight! Fuck yeah! *hmmgh* You little tight boy pussy, I’m gonna stuff you with so much nut. *moans* fuck baby, you’re gonna make me cum! I wannna fill you up baby, take… *moans* these big fucking….. *groans* NUTS!”.

Brittany’s eyes cross as she bottoms out Into the breeding mount, cum exploding into the condom on the other end. *hngh! Hnnngaah*, Brittany grunts as she thrust a few more times. Her balls contract, forcing wads of cum up her now doubled cock size and into the tight breeding mount. Brittany thrust two more times, the second one on perfect rhythm to her cock as it shoots a long rope into the cum balloon. Brittany thrust again for an even bigger load, this time with her tongue falling out of her mouth, followed by two more loads both equally as huge as the previous two. This continued for 20 more minutes, ending with Brittany hunched over the mount, her ahegao face resting onto her couch cushion sized breast.

Right before she passed out, you noticed she stopped growing after she started orgasming, but her pussy definitely grew a few inches during the climax. Something to keep in mind for further incident.
