Joan carefully slid her panties down to the floor and stepped out of them, leaving them on the floor with the huge mound of shit heaped in the back. It was a spectacular sized load that would not be out of place for a farm animal to create.
"Momma, I just came from out there and there were lots of guards walkin' around,” Becky said. “Maybe you should go out there and check things out first?”
Joan opened the door again with a loud creaking noise, and gently closed it again after surveying the area once again. Becky was right. In order for them all to escape, they would need to get rid of the guards - or create a distraction somehow.
"Alright, I'll go first. The rest of you wait here and I'll see what I can do." Joan said.
Exiting the building, Joan could see the long dirt road she came in on being lit up a row of lights every 20 feet or so. Every so often, a guard patrolling the area would appear under the light and disappear again once they left it.
There was a large building on the opposite side of the farm, just beyond the pen. It looked like a large warehouse, with several garage doors in a row. Bingo, she thought. There may be a truck or something inside the warehouse that she could use to escape with the rest of the herd.
Joan crept along the fence towards the large building. The night air caused her four nipples to get fully erect, and her hardened, gargantuan breasts were completely full and in desperate need of milking.
She realized then that her nipples had grown in proportion to her massive bust size. They looked positively huge, each one stuck out four inches from the base to the tip. They were big enough now that she could wrap her fists around them, and she did. Pulling on them caused generous spurts of milk to shoot from them onto the grass.
The relief was immense as her cock began to stiffen from the pleasure of it. Her half limp monster cock swung between her legs and she knew that too was in need of release. She fell to her knees as it continued to elongate and harden, inching upwards as it did. Within moments it was nestled between her four huge tits.
It reminded her of the time Frank had asked for a titfuck on their honeymoon some decades ago. She obliged his request, but it was a bit cumbersome with her C cup breasts.
Obviously her situation had changed. Realizing she could now titfuck herself with little effort, Joan bent forward and pushed her four boobs together, sandwiching her dick between her 80 inch bust as she began to rhythmically buck her hips. Her tail began to sway back and forth along her huge ass as she made every effort to not make noise. Thick, creamy milk leaked like a torrent from her huge nipples, coating her massive rod and its warmth running down her legs.
Joan threw her head back in pleasure as her pointed ears twitched, causing her to lose balance as she lost her footing and fell back onto the grass. She used one hand to wank her nipples, causing milk to surge from them as she massaged its creaminess into her breast flesh, and used her other hand to stroke her cock's massive length. She took turns milking each of her four breasts as Her mouth fell open, her tongue lolling out of her mouth in absent-minded bliss.
As she built towards orgasm, she paid no mind as her asshole suddenly opened, and a long, thick turd emerged, reaching 12, then 16 inches long and then began coiling up between her thighs. She closed her eyes and spread her legs, savoring the intense sensations she was experiencing, while the mound of poop built up between her thighs, covering her balls. Those sensations caused her to quickly reach orgasm, her hips spasming as her cock erupted like a fire hose, coating her tits in massive amounts of cum.
Coming out of her post orgasmic daze, Joan realized what a mess she’d made. Her cock laid limply between her four tits, which were covered in milk and cum. Sitting up, she could see the huge mound of shit she’d just produced. Whatever was in the syringe that Jeb gave her had changed her in some very unusual ways.
She did her best to scoop the cum off her chest, wiping her hands on the grass. The insides of her thighs were filthy, and would need some way get cleaned off. In the moonlight she could see the shimmering of water in a long trough beside the fence, so she got up and went over to it, placing her hands on the edge and carefully dipping her ass into the water. She washed her ass and balls as best she could, then got up.
She continued along the fence and finally approached the door of the warehouse. It had a magnetic card reader and was locked, and with no windows at eye level it was impossible to see what was inside.
