Before getting to the good stuff, Ari took a moment to make sure Lori was okay with what she had planned. Claire and Silvana were going to perform their own experiments, but Ari had intended for it to be herself, Lori, and Renna as the 'second squad'. But, Lori and Renna seemed to have a bristly relationship with each other.
'Is it fine?' Ari mouthed at Lori, still wrapped in her embrace, pressed tight to the other girl. 'Renna?' she mouthed next, to make herself clearer. She gestured her head, subtly, back at the wolfgirl.
Lori's eyes flicked over Ari's shoulder. She shrugged, unconcerned—a yes. Ari scrutinized her, making sure Lori wasn't being blase because of the bizarre dynamics of the group … because she viewed Ari as her 'owner'.
Ari was satisfied. Lori meant it. Lori and Renna weren't friends, but they didn't need to be friends to have fun together. And, Lori wasn't the best at masking her emotions, either. Ari saw more than a lingering interest for the monster between Renna's legs.
Maybe their vague dislike of each other would even make things better. That was a thing, wasn't it? 'Hatefucking'? Not that they hated each other; that was going too far. It was a built-in species dynamic—the same reason Claire and Silvana had found companionship so easily, but in reverse.
Ari grinned. "Okay. Let's get to it, then." Her hands went to the hem of Lori's shirt, and she helped tug the clothing off, revealing Lori's smooth skin and hard, pointy nipples. Claire and Silvana were pretty flat up top, but Lori and Renna weren't—Renna having the most by far, with Lori on the medium side.
Ari gave them a squeeze, feeling the echo sensation on her own tits. It sent a shiver down her spine. Sex by itself was great … but getting to feel two sets of pleasure? Her own, and Lori's? Ari couldn't wait.
Ari tugged down Lori's elastic pajama bottoms, and Lori kicked them off. Ari pouted when Lori took her panties off, not letting Ari have the honor. Lori blinked at the reaction, and Ari clarified for her: "I wanted to do that." She pointed at Lori's now-discarded panties.
Lori rolled her eyes.
"Renna's substance, then?" Lori asked. "We want to see what it does, before we … finish experimenting with Claire's?"
Ari nodded. She gestured for Renna to come over, and she did. Lori and Renna barely acknowledged each other, though both their ears flicked. Maybe Ari shouldn't have picked this setup as the trio … but then again, maybe their vague hostility was exactly why she should. Getting to explore each other's bodies might warm them up, at least in a small way. Then again, maybe it'd backfire. Ari hoped not. She'd take the event as it came, watching her two partners. It would be hard, though, when she knew she'd be having so much fun.
Ari grabbed the flask with Renna's harvest in it, then returned to the group. Her eyes flicked to Claire and Silvana. They'd already started, but were too occupied with kissing each other, not moving to the main event but just basking in each other's mouths. It was surprisingly chaste—hands not straying. Ari grinned at that, then turned back to Lori. Lovebirds, she thought.
"Well," Ari said. "Time to find out." She took a swig of Renna's essence, swished it around and enjoyed the flavor for a second—or the lewdness of the act, more accurately—then swallowed.
Ari passed off the flask to Lori, but before it had crossed hands, she felt the effect take hold.
Her breasts started to tingle, then, in one of the most bizarre sensations she'd ever experienced, to grow.
"Oh," Lori said, her arm going up to press at her own breasts. "I—I feel that too."
Right, because their sensations were linked. Ari shivered as the effect continued. "This is weird."
Ari looked down at herself as her tits—not as flat as Claire or Silvana, but smaller than Lori's, who was already on the lower end of medium—grew. Ari's heart slammed in her chest at the foreign sensation, and in excitement. She wasn't super insecure about her body, but she had wished, a few times, that she had bigger boobs. Her strict training routine had always left her lean, not soft and curvy. The same for most adventurers, besides people without physical classes, or who were naturally endowed.
She cupped herself and jiggled. Lori shivered at the linked sensation—Ari wasn't stimulating herself, but the link was bizarre to experience, even so—then Ari pushed and squeezed, moving them about, getting a feel for the new, temporary her.
"Wow," Ari said. "I've gotta be at least a full size up. More." She cupped herself in a more flattering way and bounced them up and down. "Do you like them?"
"They're, um …" Lori trailed off. "They're nice."
Ari's grin widened. Coming from Lori, that had been a resounding 'yes'.
"How big do you want them? What's your favorite?"
Lori stared for a second longer—like she couldn't tear her eyes away—then met Ari's gaze. She paused. "It's up to you."
Ari rolled her eyes. "I asked, didn't I? How big do you like them?"
"Whatever's fine," Lori said.
Ari realized why she wasn't answering. The question was unfair. Lori thought she'd hurt Ari's feelings if she said she wanted Ari's tits bigger. And … maybe she would hurt her feelings? Ari didn't know. She was a bit insecure about it.
So Ari would have to pick herself.
But, Lori's concern spurred Ari forward to give her a quick, chaste kiss. "Why are you so sweet?"
Lori's ears flicked, as if she were offended by the word. "I'm not. I just don't have a preference."
"Right," Ari said, rolling her eyes. "I totally believe you. Anyway, we're experimenting, so go ahead and take a drink yourself." She grinned at Lori, knowingly. "Even though yours are my favorite however they are, too. But we're trying to figure out how the potion works."
Well, not potion, but it might as well be. Just a very lewd sort of potion.
Lori took a drink from the flask.
