Aleanna let out a small squeak as she was lifted up, spread eagle into the air, looking at her mistress with curious eyes. She gave an experimental wiggle, but only achieved getting her boobs to jiggle.<br/><br/>Chocoleanna nodded with an obedient "Yes Mistress," and took the chain, giggling as her chocolate hardened with it's touch. She walked behind her sister, and bent over, moaning a little as she slid the first few links of the chain up her own ass. She gave a little flick of the hip, causing the chain to jiggle and clank, before she knelt down, and kissed Aleanna firmly between her cheeks.<br/><br/>Aleanna's eyes shot open with a gasp, as Choco's tongue ran rings around her asshole, then they went half lidded, as she moaned in delight. She continued moaning for a while, as Choco continued her attention, then, her eyes shot wide open, and she cried out, futilely struggling against her bonds out of reflex, as her clone began to flow up her asshole at surprising speed, the chain sliding up her pucker, link by link.<br/><br/>Aleanna shut her eyes, gasping, moaning, and screaming as more and more of the ice-cold chain entered her. Then, she started to gurgle. Chocolate flowed out of her open mouth, then, the tip of the chain, strangely clean of chocolate began to exit. The bubbling mass continued to flow, forming a blob on her chest, which solidified back into Chocoleanna, straddling her sister, kissing her, her legs wrapped around Aleanna's hips, several links of the chain hanging from her ass. She allowed herself to flow down Aleanna, drawing more and more chain through her, until she reached the ground. She morphed into a blob again, and reformed, having turned around, so the chain coming out her ass led to Aleanna's mouth. Choco got down on all fours and, moaning, crawled forward, letting the chain pop out of her ass, one link at a time, until at least 8-10 feet hung out of the front of her sister, who had already cum at least once from the treatment, judging by the clear fluids mixing with the chocolate around her crotch..<br/><br/>Choco slithered up to Serna's leg, and hugged it, "Is this to your liking, mistress?"
