"The upper chests shall converge..."

"Well... this one says 'The upper chests shall converge, and so the participants shall remain inseparable by their chest region and any tissues residing within.'" Lindsey says, giving a funny old-sounding voice. "Think that means our boobs? What does it even do to them?"
"I... don't know. Wanna go for it?" Jane asks, smiling. She should have known Lindsey would have said boobs first.
"Fuck yeah. Let's do it." Lindsey grabbed the book and held it on her lap, as she read and re-read the passage. "Stan sam‍milt... s-sammilit rahen, rooke rahen... Stan sam‍milit rahen, rooke rahen..." She repeated. As she said the quote again and again, a slow tingling emanated from both Jane's and Lindsey's nipples, slowly spreading across their areolas and the areas surrounding.
"Ooooo... do you feel that, J?" Lindsey asked, stopping the repetitions.
"Yeah... it's like... someone's pinching my nipple..." She brought her hand to her chest, covering it, but it did nothing to stop the feeling. "D-don't stop repeating it!" Jane said, quickly.
Lindsey continued repeating the phrase, her accuracy going up. Suddenly, though, the tingling stopped, causing Lindsey to stop, too. "Fuck, did I screw it up?"
Jane sighed. "...Try aga-"

They were interrupted when they were suddenly pulled by their breasts. Specifically, they were pulled into each other by their breasts. Lindsey's slightly larger tits hammered themselves into Jane's average ones, an immediate fusion beginning. The mass of both grew as they connected, though their nipples were completely obscured during the process.
"L-Linds! What the hell?" Jane asked, completely surprised by the sudden impact. "C-careful! S-stop!" She said, confused.
"T-this isn't me, J!" Lindsey returned, looking down. She sharply inhaled when she saw her breasts, having seemingly connected to Jane's.
"J-Jane! Look!" She said, alarmed.
Jane glanced down, and shrieked. "Oh my god, our boobs! They're..."
"They're f-fused!" Lindsey finished. "They're... we're stuck!"
Jane quickly reached up to feel them. She fondled them, trying to find a split between their breasts. To her astonishment, though, she could easily trace a fine line from her neck to Lindsey's, proving they share breasts. "How the hell...?" She asked. She started to lean away, experimentally, but not even a foot apart she was stopped by a tug, keeping her and Lindsey stuck together.
"So that's what this book does..." Lindsey noted. "It's actually magical... I thought this was just an elaborate joke, but... we're stuck now. Like siamese twins..."
Jane stayed silent; that isn't to say she wasn't enjoying it. She continued her small tugs, each time hitting a smaller-than-foot limit between them, forcing her to press her chest back against Lindsey's.

"So..." Lindsey said, wrapping her arms behind Jane. "What do you wanna do?"
