"So you really did grow another one," Sylphie said. Sylphie had come to check up on things after Aisha went running downstairs screaming something in the lines of 'there's tentacles in the house!'
Roxy was flat on the bed, juice still oozing out of her, spent. She occasionally let out a moan or two but mostly just hummed something in demontongue.
Eris stayed sat, while Sylphie hovered over her, observing.
"Yeah."
"It looks different. You also have balls," she said, giving her a touch. The cock jerked once but Sylphie quickly moved back. "It moves."
And so big… no, long?
"It does," Eris said. "Even more sensitive than typical cocks. It's almost as intense as my clit," she said, brimming with pride. Her cheeks steadily came to a flush.
"What about your vagina?"
"It's gone. But my ass is more sensitive now," Eris said, lifting her butt up for Sylphie to see.
Sylphie touched Eris's butt and noticed moisture in there. "Almost like a vagina," she said. "It sort of looks like one too; the wrinkles have straightened. Does it feel odd to poop?" She went a tad closer. "Smells like it too; nothing like an ass…"
"I haven't gone yet," Eris said. "I'll tell you lat- ahh!" she moaned when Sylphie touched her. "It's sensitive." Her cock had stretched a fair bit and was starting to wiggle about. Before long it bent and slowly slid into Eris's ass. "AHH!" It stretched and stretched and when her ass was fully plugged started vibrating. "Oh yeah," she panted. "See, it's- ahh! Mmhh! Yeah!"
Sylphie wasn't sure what was happening or why. She just watched. At first with curiosity, then with a mild uncertainty. But before long her nipples stood erect and her vagina slowly moistened. The more she heard Eris's moans, the more she saw that mindless pumping action and vibration… the wetter her vagina got. SO much so that she soaked her panties and started rubbing without even realizing. Just how good… must it feel?
"AHHH!!! AH AH FUCK!!!" Eris howled and a burst of cum oozed out of her along with the spent penis; yet her hips still shook for at least a minute as she nearly knocked herself out. She kept panting and panting and fell face first into the bed where Roxy welcomed her into her sleepy. arms.
"Mmmgh…" Sylphie panted but stopped. She sat down next to Eris and observed her butt. "It's semen?" She wondered taking a bit of that cum into her fingers and examining the texture.
"Yeah," Eris said. "I have balls if you haven't noticed."
Sylphie giggled. "Can I?"
"Go ahead. I don't think there's any refractory period like Rudeus. It just keeps on providing."
Sylphie touched the cock and started giving it a stroke. The thing didn't respond at first but slowly hardened when she poked around in Eris's butthole. The butthole didn't feel like one, not as tight, not as constricting. But rather it was warm and welcoming like a vagina. Sylphie had her doubts about how Eris would use the bathroom but that wasn't a concern right now. After all, the cock had hardened and her pussy was more than screaming for some action.
"So, umm… turn around," she said. Eris obliged and faced Sylphie.
Sylphie meanwhile sat on top of Eris's cock and was about to take it into her pussy.
But instead, the thing slowly… slowly reached for her ass.
"Oh!" Sylphie cried out. "Fuck?"
