That night Amy was alone in her room, sleeping naked with her newfound dick, but in Mark's room the three trio of females were all wide awake and... exploring Mark and Josh's new sex.
Josh had taken it upon himself to enjoy his new vagina with Victoria, the two of them grinding their vaginas against each others' and enjoying the new found sensations. Mark however was simply pleasuring himself with his fingers, all three of them were very vocal about their pleasure, with loud moans coming from the room that surprisingly didn't reach Amy's room.
When the three of them were done with their self pleasuring Mark had opened the drawer that Amy had told them their surprise was in. Pulling one of the objects out left a very deep blush on each of the trio's faces. In Mark's hand was a dildo, one of three in fact as Mark handed them out. Each one of them held their new toys with a blush and a look of need.
Victoria however was the first to take the plunge, sticking her dildo in her vagina and using it with ease, thrusting it in and out as Josh as Mark shared a look between each other before blushing.
Josh stuck his dildo in Mark's vagina and Mark stuck his in Josh's vagina, something breaking inside both of the new girls before they started thrusting the dildos up and down in each other's vaginas. But as three of them enjoyed themselves, their next changes began.
Flesh began to gather under both Mark and Josh's nipples, which were becoming more swollen. Victoria's breasts on the other hand quivers before growing slightly larger, her change not nearly as major as Mark and Josh's. As both Mark and Josh were moaning in pleasure their chests began to swell, becoming puffy and soft as small, pert breasts grew on their chests, slowly becoming bigger as they continued to thrust the dildo's into each other.
Over the next few minutes those breasts continued to grow until they were large C cups and bumping against each other, at which point both Mark and Josh noticed them and let go of the dildo's which fell out of their vaginas as they blushed as Victoria came over to them.
"Look at us, slowly becoming sisters." Victoria said quietly as she put her arms around their shoulders as both Mark and Josh blushed and looked between each other and Victoria before all three of them turned to face each other. Mark was left fascinated with his breasts as Josh hugged Victoria, squishing his breasts against hers as the changes continued.
Both Mark and Josh's asses began to inflate, becoming bigger and more feminine as their hips expanded. Mark's shoulders crunched inwards as Josh's midsection caved into a similar hourglass figure to Victoria's. Following up Mark's midsection did the same as Josh's as Josh's shoulder crunched inwards, finishing off their changes for the night as all three of them looked between each other with blushes on their faces.
But there was one other thing that all three of them had, small bits of fur appearing around their vaginas, it was small, but it was there, their first animalistic traits as all three of them climbed back into the bed and huddled with each other for warmth and because they wanted to.
