The two women haply accepted the invitation, and started moving inside at a normal walking pace for a human, which somewhat shocked mother and son. Speaking of which despite time having passed, the slime on them didn't seem to dry up or go anywhere, they both looked like they were doused in water. Whitney was a tall woman at almost six feet tall and despite her age she was in incredible shape and it was all for everyone to see as her clothes were clinging to her skin, her E cup natural breasts were the most prominent feature on her frame, but the outline of her pussy on her pants was a close second right now. Jeff had never seen his mother in a sexual light but he couldn't help but stare at her form, even her blonde long hair seemed a bit more attractive than usual.
Jeff was no ugly duckling himself, and Whitney was also seeing him in a new light, especially the large bulge in his pants, which he was not ashamed to show the world anymore. The closer they both got to the kitchen, the more the shame for seeing each other like that faded. Megan stopped to look at a painting in the hallway just before the kitchen when Lucy, the oldest daughter and Jeff's twin came to see what the commotion was all about. The same as had happened with mother had son happened with the daughter. Lucy was a free spirited woman that never had the same hair color for more than six months, now it was green. As for the rest she had taken to her mother, being tall and busty, although a bit taller at exactly six feet, one inch bellow her brother. As one cannot gain something without losing something else, her bust was "only" DD cups but that made her the largest sister in the house in any form or measurement.
While Jenny was covering Lucy in her slime, Jeff and Whitney showed Megan the painting she had made. Shame being long gone, Jeff stared at her ass while she explained and Whitney stole glances at his still hard cock whenever she could. The two of them were incredibly arouse and only made halfhearted attempts to hide it.
Meanwhile, the commotion attracted the last two member of the family to the hallway, which was luckily large enough for all of them. Megan soon let go of Lucy, who was regretting not wearing a bra a little, and moved on to Zoe the second oldest sister. She had the very dark hair of her father and the same blue eyes. She was short for the family standards, but average for most women with equally average boobs, and fortunately (or unfortunately for her) she was wearing a skirt while gave Jenny full access to her backside, not that she minded. Mean while Lucy was greeting Megan who was done looking at the painting. The two slugs took their time covering all women with slime, which meant Grace was just looking for a minute.
Grace was the youngest of the sisters. She had inherited her mother and fathers few Irish genes making her a ginger and very different from the rest of the family in that regard, but she was still a tall woman with above average breasts.
While the neighbors took their time introducing themselves, Jeff noticed a hole in his mothers yoga pants and one in her shirt. Curious he decided to investigate with his fingers the hole, but accidentally touched Whitney's skin making the woman feel an electric shock and pleasure as he did. He felt the same on a milder scale, due to being his hands. She turned back to him only to see his shirt and shorts also had a few small holes in them. She was curious but that was the extent of her reaction, but the arousal was not subsiding and that feeling of being touched didn't help it at all, if she wasn't already soaked there would be a wet spot in her crotch without a doubt.
Jeff was really focused on Whitney's tits and how her shirt clung to them despite the bra, but it all changed as Lucy finally was done with Megan and Jeff could see her breasts almost as if she was nude. A white shirt and no bra is a bad combination if you get wet, but Lucy like Jeff were pretty comfortable around each other, they were twins after all, they considered each other their best friend and had never seen each other in a sexual light. Of course all of that was out the window now, and Jeff had no shame in staring at his sister's tits, and he even took to rubbing his cock from above his pants. Lucy saw that and was horrified, but she froze and just looked, then she was less and less horrified for each stroke until she was more aroused than anything else.
Whitney was never a jealous woman, but she felt sad that her son wasn't paying attention to her anymore and tried make her superior size count by pushing it outward. What she didn't know was that her bra strap was, like everyone's clothes. Being corroded by the slime and her efforts broke it.
A perverted idea flashed through her head and, she quickly asked Jeff to help her remove it, and her wet shirt was making it difficult, which was true.
Jeff jumped at the opportunity as his mother lifted her shirt up until her shoulders and he helpfully removed her bra after running his hands down her sides and back. The pleasure both felt was well above what should be possible. Jeff could tell he was leaking pre cum despite his state and Whitney was dripping from her cunt. They both felt they could understand why slugs loved physical contact so much.
Unfortunately for them, before they could loose themselves more, Grace's stomach made a pretty audible sound, which made the shy girl get beat-red.
Grace – "S-sorry."
Whitney – "Hey we are all hungry sweetie, let's eat"
As she said it she put her shirt back on, much to Jeff's sadness, but now he could see the outline of her tits much better anyway.
