"Emilia.." Manuela would say with a lascivious look on her face. "..are you thinking what I am thinking?"
"Oh yeah.." Emilia grinned, as she began to undress. She was wearing a steel breastplate throughout most of her time out on the ocean, which somehow changed to fit with her growing breasts, and some simple clothing made with by Novofortian tailors. After a long day of changes and sailing through mist, she was finally able to take it off. Her green undershirt did little to hide the top of her large breasts. She took it off as well, exposing her bare chest to her sister. Next came the pants and underwear. They had widened considerably to fit Emilia's wider hips and thighs. She removed them to reveal a large ass and a bare vagina.
Manuela would follow in removing her clothing. Starting with her green coat, then her button-on undershirt, which she slowly unbuttoned to reveal her breasts that were basically the same size as Emilia's. She would then remove her pants and underwear as well. Even with the changes continuing, they were still very much twins in appearance.
Emilia's hair had grown a bit since she left the ship, as it now reached her shoulders. She, Manuela, and the rest of the crew thought this was normal due to the mist changing their minds, and the sailors in the tavern were too drunk to notice. Maneula's ponytail had lengthened to reach her back. Nobody happened to notice her hairstyle changing either.
"Oh, Emilia.." Manuela moaned as she begun to caress Emilia, fondling her breasts and ass.
Emilia moaned back at Manuela, returning the favor by finger her sister's new vagina as she also grabbed her ass.
Manuela would take her sister and herself down onto the bed, with Emilia on top, where they took turns fondling and fingering each other for a while. Sweat slowly dripped down from both of their bodies.
"Oh.. Manuela.. I'm gonna cum!" Emilia would say as she bit her lower lip in excited ecstasy.
"Me.. me too!" Manuela would moan in response. Before they knew it, they ejaculated some liquid from their vaginas, sighing in pleasure as they both reached a state of orgasm. They finished off this part of their intercourse with an elongated tongue kiss. Afterwards, they wiped, and even licked some of the sweat and fluid off of each other's bodies, and prepared for their next part of intercourse.
Emilia would be atop Manuela once again. This time, they would go straight to scissoring, rubbing each others clits and moaning as they did so. Within a few sexy minutes of sweat, moaning, and vaginal fluids, they would both orgasm again, sharing another long tongue kiss afterwards. Both of them were breathing heavily, since they spent a good long time fucking each other.
"Manuela, I love you." Emilia would say, giving her another kiss.
"I love you too, Emilia." Manuela would respond.
The two would clean each other off as they did before their bout of tribbing, wiping and licking the sweat and vaginal fluids off of each other, before they simply spent the rest of the night cuddling each others nude bodies, falling asleep in each others arms.
