Once Frieda and Lucy had recovered from their orgasm, the new addition to the group made a suggestion:
“Thanks for the help you two. I'm sure you understand how hard it can be for me and Lucy to deal with our urges. Let's head back to the boardwalk and get some food now that we've worked up an appetite.”
The sisters, not entirely sure what their relation to Frieda was at the moment, decided to go along with her and Lucy for the moment. As they returned to the boardwalk however, the sisters saw a perfect opportunity along the way. They altered their course slightly and passed over a man buried up to his neck in the sand and Claire dropped a pill into his mouth before swinging back over to Frieda and Lucy. The two girls then turned their ball-heads around and watched to see what happened.
Since he was buried, all they saw at first was that his head became more feminine, with thick lips, chubby cheeks and long, platinum-blond hair. Just before they gave up on seeing anymore of the transformation, they saw what looked like more of the victim's body emerging from the sand. First it was a pair of shoulders, then a pair of beach-ball sized tits, until it looked as if the victim were only buried up to the waist. This illusion was broken when they stood up out of the sand, revealing that under the sand was the six foot tall body of a male bodybuilder, with the bimbo torso attached where the head would be. The sisters were unable to see what their victim did next since the crowd became too thick closer to the boardwalk.
The four women had soon gotten some food from one of the many stands and were now sitting at a table as they ate. Luckily for Jen and Claire, they were able to lay their equine body sideways on a bench in such a way that made it easy for them to bring food down to their mouths despite the distance between their arms and their heads. As they ate Frieda and Lucy looked around at the people milling about on the boardwalk, which included many people transformed by Jen and Claire's pills.
“It's so weird seeing so many Mutants around, back in Germany me and Lucy were the only one in the entire country. Her though you can barely go anywhere without seeing at least one.” observed Frieda, before taking a bite of her fish sandwich.
“That's why we wanted to come here during our post Collage world tour, it's nice not having everyone stare at you like some kind of freak show.” Continued Lucy
“Yeah, we can't really imagine what that would be like. Around here, we've never really been seen as anything other than completely normal” stated Claire.
“Maybe once we're done travelling we can come back and find a place to live in town”
“That would be the nice Lucy, just as long as it's not a town-sized mansion, no offence to you two”
“I get it, we've lived there all our lives and it still feels like it gets bigger everyday” Jen replied, completely aware that their house HAD grown larger almost everyday since she was cursed.
Their discussion trailed off as the four women focused on finishing their meal. As they ate, Jen and Claire noticed Frieda and Lucy's cocks growing erect, until it seemed like the two of them couldn't ignore their lust anymore and began using three of their four arms to masturbate while the fourth one continued to feed their breast-mounted faces more fries. Not content to just pleasure themselves, the conjoined fish-woman used their feet to tease the tip of Jen and Claire's horsecock. Since the two sisters had never cum with their new form, they were on a hair trigger and the sisters soon found themselves painting the two women sitting at the next table over with their semen.
Jen and Claire were worried that the women would get mad at them, but when they stood up to apologize they noticed that both women had begun to transform. The only conclusion either of them could come up with was that because their heads are also their balls their semen gets infected by any pills they cough up like this. Already thinking of the potential implications of this, both sisters decided to watch the show about to unfold before them.
The first woman's transformations began with her arms growing a dark crimson plumage, while her hands simplified into a single large finger and thumb, as if she was wearing oven mitts. Next her legs morphed into scaly bird talons, and a feathery tail grew behind her. Her bikini bottom then tore off as two, foot-long, cocks grew just above her vagina, leaving the woman as a twin-dicked harpy.
The other woman, who seemed to be the other's wife judging by the matching wedding bands they wore, started her transformation with a new pair of legs growing from her hips. These legs rapidly grew as her entire lower body stretched out into a second torso, which was soon covered in indigo scales that caused it to morph into a more reptilian form as they spread. The woman's draconic lower body was completed by a long and thick tapered tail and webbed spines that grew down the spine of her dragon torso. Finally, six large feral dragon heads attached to six-foot long necks grew from her dragon body's shoulder, three on either end of the spines.
The newly transformed couple were still looking over at the group, but instead of looks of anger or annoyance, they were looks of desire.
“Wow, that's some impressive 'firepower' you two have got there” the dragon-taur purred.
As she said this one of her feral heads licked some of the sister cum that hadn't yet slid off her scales, causing her to grow another pair of arms, as well a making a two-foot dragon cock to grow between her back legs
“mmm, it tastes lovely as well. How would you and your friends like to go somewhere less crowded and have a little fun?”
The sisters looked over at Frieda and Lucy, who gave them an enthusiastic quadruple thumbs-up, before eagerly accepting the woman's offer.
As they left the crowded boardwalk, the couple introduced themselves as Anges, the dragon-taur, and Steffany, the harpy. It turned out that “less crowded” didn't mean “private” as Anges stopped only a couple dozen feet away from the boardwalk before stopping. The area had a good amount of space, but there were several people nearby sunbathing and whatnot. Regardless, the dragon-taur seemed fine with the potential audience and bent herself over and presented her pussy and asshole to the sister before declaring:
“Take your pick!”
Still horny from watching the couple transform, Jen and Claire immediately mounted Anges and rammed their cock into her tight pussy. Their other three companions, not wanting to be left out, joined in on the others and turned the threesome into a six-some. Steffany flew over the sisters headless upper body and grabbed their shoulders with her talons as she lined up her twin cocks with the pussies on their shoulders. Frieda and Lucy meanwhile, moved in front of Anges and guided three of her feral heads to the canine cocks between their shoulders, which the heads began to eagerly fellate. Wanting to leave any of her extra heads out of the action, Anges had two of the remaining ones begin eating out the nipple-pussies on Frieda and Lucy's lower pair of breasts while the last one wrapped under her lower torso and started giving her own cock a blowjob. Steffany, cocks now hilted in the sister's shoulder pussies bent forwards and began ticking the strange nipples on the sisters four breasts with her feathers.
All this stimulation meant it didn't take long before Jen and Claire found themselves on the edge of climax, knowing that their semen now carried the transformative power of the pills made them think twice about cumming inside Anges, though if they pulled out their was a good chance that they could hit a bystander(not to imply that outcome was considered a bad thing by them.) with just moments until they came, the sisters made a decision.
