In response to Jen's question, Lucy simple let out a bark and gave her a quick lick on the cheek. The two sisters deflated, the tension from the idea that the pills might have allowed lucy to talk gone. Jen and Claire took another look at the Fair that they had corrupted with their pills, and while they would have loved to continue it was starting to get really late and neither of them had eaten dinner yet.
"Alright Lucy, let head back home." commanded Jen
In response Lucy stood up and began walking back they way they had come, finding the trip taking much longer due to their smaller size and bipedal stature. Luckily, when they got back they found that while they had to eat out of bowls like Martha back when she was part of Lucy, their bowls had actual food in it instead of the kibble Lucy was eating. After dinner, Lucy headed off to the sisters shared room, which had once again changed to accommodate the fact that they were a part of the family dog.
Once inside the room Lucy flopped down on the couch and began stroking her cocks, the sisters soon discovering that their television, as well as several other electronics in the room now had voice controls, allowing them to spend the rest of the night watching shows while Lucy lazed around and masturbated. Occasionally one of the six Martha's would flutter into the room to clean up and “assist” with Lucy's self-pleasure. Soon enough Lucy had tired herself out and the three of them went to sleep.
The next morning, Jen and Claire were woken up by Lucy finishing her first masturbation session of the day. Lucy then brought them out to the kitchen for breakfast before she crawled up onto the huge couch of the sisters fused parents and began to snuggle with the massive sphinx-taur as they drank their morning coffee.
“Good morning you three.” Greeted the snake-like that was originally Claire's dad, while the red-skinned left hand of Jen's mother reached down and began rubbing Lucy's belly. The two sisters returned the greeting and chatted with their parents for a bit. Eventually the belly rub stimulated Lucy enough that her cocks once again grew hard, but instead of stroking her own cocks, Lucy adjusted her position so that she could fuck the pussy-face that was originally Jen's father. Even her mismatched dicks, being nearly twenty feet tall each, were not large enough to fill the pussy of the two-hundred and fifty foot tall behemoth their parent had become, but Jen's dad clenched her muscles and “sucked” on the pair of cocks inside her.
Lucy and her two passengers were taken by surprise when one of the Marthas, the one with red wings, began fucking their mostly neglected pussy with her twenty foot shaft, adding even more to their already overstimulated body. I wasn't long after this that Lucy blew her load, filling Jen's dad's mouth with her seed, while she clamped down on the Martha's horsecock. Not long after both the Martha and the sister's parent came, Lucy's belly bulging with cum while the parents horsecock once again unleashed a room-flooding torrent that caught Lucy in the crossfire.
The five other Martha's soon went to work cleaning the mess, with the red-winged one joining once she had recovered from her post-orgasm daze. While Lucy let herself be cleaned, Jen and Claire were left in a decent position to feed anyone in the house a pill, they might even be able to crumble a pill and catch all six Marthas with the dust.
