Jen looked at her little sister, sitting on the floor in the bathroom stall, smiling at her and asking her to merge her with a pair of pantyhose for the second time. She could hardly believe it. The merging must have done something to her sister. And now, with that in mind, she also realized, that Sam hat incredibly smooth skin. She seemed to have not a single hair on her body, except from the long dark mane on her head. Even her eyebrows wer gone. Her skin tone also appeared a little darker and when she moved, Jen was almost certain, that there were some sparkling little spots on her sisters skin. Jen shook her head. This was no good... She really shouldn't merge her sister with anything again. Also, she felt really worried about Daisy now. But just when she wanted to protest, she heard someone enter the girls room, just as Sam bent towards her and said: "Pleeeease!"
Without further hesitation, Jen put on the gloves, grabbed the tights with one hand and Sam with the other and -swooosh- merged them again. From outside the stall, she heard someone shout in surprise. "Sorry! That was my phone!" Jen shouted quickly, before gathering her stuff together. After having put everything back in her bag, she looked at the Sam-tights. What should she do now. Sam was her sister. Wearing her felt absolutely wrong. She should better get home real quick and return Sam to normal - if that was possible - and hope for her to snap out of it eventually.
Sam in the meantime was dangling from Jens hand, feeling the air pass through her and hoping, no wishing, wanting, longing. for Jen to wear her. Just thinking of the sensations she would have then, almost made her come - even though, as a pantyhose, she could not come at all. But she loved being constantly on the brink of an orgasm. And she loved being so close to her owner - no, wait, her sister. That was the word.
