All of the mutants created by the outbreak were slowly settling into their temporary rooms, and now wanted to explore their new bodies without the fear of spreading their condition. Throughout the hotel, several orgies began to start, and those who wanted privacy were dragging friends and strangers alike into their rooms.
Flora and her three sisters, sensing that after their family chat their parents wanted some more “alone time” and went to hang out in Margret and Izzy's room. Once there however, they all began to feel their lust building. Margret insisted on staying in the room, claiming that she wasn't horny, and Izzy immediately left to find her girlfriend, leaving Flora and Sophia to look for a partner, or partners, of their own. Their search ended prematurely however when someone called out to them from behind.
“I never imagined that I would see another person with a body so similar to mine”
The sisters turned around to find a young woman who also had a spider-like lower body, though her back abdomen lacked the breasts and cock that theirs did. Unlike the sister who had lacked any clothes that fit their oversexed body, the other woman was wearing a blouse and a long skirt that was lifted up in the back by her spider abdomen, but covered her front decently well
“My name is Janet, Nice to meet you miss.”
“Oh, hello,” Flora answered, “I'm Flora and this is-”
“I'm her younger sister Sophia” Interrupted the face on Flora's crotch.
“Sorry Sophia, I didn't see you there. So you two were fused together when you mutated?”
“Yeah, when I started mutating I lost control and infected Flora as well and we ended up fusing together, that's why I don't feel to bad about being stuck to her crotch.”
“Don't be so hard on yourself dear, when I transformed I was only barely able to keep myself from infecting my son, why he might have even gotten fused with me like you two.”
The two sister furrowed their brows in confusion at Janet's story
“Your son?” Asked Flora, “but you look the same age as us.”
“Well looks can be deceiving, I'm seventy years old. When I mutated my body regressed back to when I was nineteen years old.”
“Wow, your old enough to be our grandmother!” observed Sophia.
“I am a grandmother, my son David has a daughter that's just about your age. I imagine that she's going to be very surprised next time I come to visit.”
As the three of them were talking Janet had been staring at the sister's nude form, and at this point in the conversation Sophia noticed the older woman's skirt begin to tent.
“Oh my, it looks like your having a bit of trouble down their Janet.”
Once Sophia pointed out her hardening cock, Janet rushed to cover it with her hands, “Sorry, I'm not used to having one of these and the two of you are just so sexy...” Janet's hands shot to her mouth after she said that, allowing her now fully erect cock to lift her skirt to the point where her sizable balls were in clear view to Sophia from her lower perspective.
“Once she had heard Janet's true feeling slip out Flora stepped towards the woman and wrapped one of her chitinous arms around her shoulders, “If you find us so sexy, why don't you bring us to your room and you can show us just how sexy you are as well.”
Unable to deny her lust any more, Janet eagerly escorted to fused sisters back to her room, and practically tore off her clothes, revealing her large, but still normal sized breasts as well as the throbbing eight inch cock.
“It's been awhile for me, and never before with, or as, a mutant, so I'm not entirely sure how we should go about this...” Janet said once she had finished taking off her clothes
The sisters though a moment before Flora had an idea, “Lay down on the bed, face up.”
Janet did as the girls instructed, spreading herself out on the single king sized bed in the room. The sisters than crawled over the woman's prone form and lowered themselves onto her, the six breasts on the underside of their abdomen pressed between their arachnid bodies, while their human halves were now facing each other. Flora took hold of Janet's cock and slid it between her gargantuan, vagina-tipped breasts, while Sophia used her pedipalps to lift Janets ball out of the way so she could begin kissing her pussy. As Sophia continued to press her mouth against her lovers fold, her canine cock-tongue began to extend from her mouth. Her appendage slowly filled Janet with its length until the cocks knot eventually slipped out of Sophia's mouth a popped inside Janet, causing her to cum on the spot, the load shot from her cock lost in Flora's endless cleavage.
However, neither of the sisters had finished yet, so Flora slipped her breasts out from around Janet's now limb cock and roughly pressed the woman's face against one of them, forcing her to pleasure it's pussy-nipple. She then guided Janet's hand to the other breasts and got her to begin fingering it. Janet had never had sex with another woman before, so she was inexperienced at first, but she quickly began to get into the proper rhythm. Sophia meanwhile was unable to thrust her cock-tongue now that it was knotted inside Janet, so she began grinding their lower halves against each other, stimulating the nipples on her and Flora's underside and causing streams of milk to begin leaking from them.
Eventually the fused sisters simultaneously reach orgasm, causing Janet's mouth and pussy to be flooded with both types of cum, while the sisters currently neglected back cock shot a powerful stream of semen onto the floor of Janet's room. Now spent, the sisters fully laid down on top of their lover and pulled her into a hug, the three of them content to cuddle for the next little while.
