It happend when Jen rushed into the metro. She had a close brush with an old lady and ripped her tights on her umbrella. Jen noticed only when she was standing in line for the club. Considering the dress code tonight, she cursed and went to a small café near by to change in the ladies room. Luckily, she thought, I got that pair of Sam's in my bag. Sam would be fine wearing ripped tights for the night. She would be inside after all. Jen hardly hesitated and put on the other pair without giving it a second thought or look. Gladly it was also opaque, covering the hair on her legs just as well.
Sam on the other hand went through the most intense Experience of her life: First, light flooded the insides of the bag. Before Sams vision could adjust, she felt a gigantic hand close around her. Excitement shot through her every fibre: We are inside! She thought, The party is about to start! To her surprise, the toilet looked much cleaner than she would have expected from a club. Also, Jen appeared distressed and would not even look at her. Something was wrong. Sam wished, she could have screamed or at least moved... Then she realized, that she felt really weird for a dress: To her, it felt, like she was bent down, with her hands touching her feet and her arms lying on her legs. Her face was right inbetween her two merged limbs with her tongue out. Inbetween her legs, her pussy felt really open and wide and when Jen grabbed her now with two hands, she felt two thumbs entering it an pulling it open. Then it felt, like her right lims wer sucked in and crumpled together while on the inside of her vagina, Jens fingers massaged all the right spots and seemed to reach ever deeper. She would have moaned loudly already, but nothing prepared her for the feeling that rushed through her, when Jen suddenly pushed her foot deep inside Sam and pulled Sams body up to her knee: Never had she felt something penetrate her so deep and thorough. It might have hurt, had she been human. But her soft fabric adjusted and it all felt gentle and incredibly pleasant. Sam could not wait for the second leg and when she got pulled up to Jens hips and she felt her tongue making contact with the strip of moist panties between her sisters legs and when two but cheeks pushed into what were formerly Sams breasts, Sam was reeling with ecstasy and somehow finally felt complete! It was weird, it was super strange, to be wrapped around her sister, but the feeling to finally be worn, to make someone's legs look so beautiful... It was perfection. Sam almost forgot herself as she more and more gave in to the pleasure. She managed to hold on by a thread, just when Jen pulled down her super tight dress and Sam realized that her Klitoris was now where the seams of the pantyhose was. The stimulation was just too much... Same couldn't possibly hold on to even one straight thought.
While her sisters personality was swept away by pure pleasure, Jen got herself sorted and went back to the queue. She was nervous now: Would the plan she had for the dildo still work? And would her sister still have a chance to meet the guy she had come here for? Once inside, Jen rushed for the girl's room and immediately got the dress out of her bag. She held it in front of her, but she just couldn't find any sign of her siter in it. "Sam?" she whispered, "Sam, do something, do anything! I can't seem to find you..." Jen was so focused on the glittering dress, that she didn't notice the slight twitch between her legs, when Sam mustered up all her strength and tried to push her tongue up against ther sisters pussy.
Jen got more and more nervous. What had happened? Did she do something wrong? Was it just the light in here? Did the gloves not work properly? Then she remembered, that she had never actually seen Sam merge with the dress and that she had reached into her bag blindly... Cold sweat crept on her forehead. In sheer panic, Jen pulled out everything she could find from her bag: First the broken pantyhose, which she dismissed, then the underwear her sister had packed for the party, then the shoes, the dildo, than all the tiny little things, eventually she checked for traces on the bag itself end even checked the gloves...
