The addiction

"Sis. I need to go back to find Mr Y again. I just can't sleep without it," Yuna plead to her sis, shaking her shoulders continuously.

"You were just on it this morning and now again?" Mikki trying to stablise herself from the shaking...

"Come'on... just for awhile only..."

Yuna's obsession with Mr Y started when she was 15 when the order came for her to use him for the first time. Ever since the first, she had been on it fourth times a day for the next 2 years, till Mikki started to tone Yuna's addiction to it by restricting it to twice a day. Oh ya, both are 18 yrs of age now, in perfect figure to die for. After years of 'training' and maintenance, Yuna has the killer looks - standing at 1.65m, she boasts of a full C breasts, small waist and slender long legs. Mikki on the other hand, as a twin, she looks exactly like her sis but with a D-cup instead. Both their nipples are pink and erected always, from years and years of massaging.

Back to Mr Y.

Yuna grabbed Mikki by the arm and walk to the basement. All along, Daddy knew what was going on in their room. After all, every room has cameras installed. Daddy grinned, awaiting patiently for his next show to start...

Yuna ran towards Mr Y with much delight. Caressing the legs, wiping it clean and turned around, "Mikki. I AM ready". Eyes wide open, showing much delight and excitement to come. The addiction was severe. The dose ultimately have to be delivered.  "STRAP ME!"

Mr Y is the nickname given by Yuna for a device in the shape of a 'Y'. The legs were spread and the hands stretched to the back, forming the 'Y' shape. Each time Yuna is on it... she gets wet straight away...

Mikki yanked Yuna's arms backwards, stretched them to the back, cuffed and locked to the wooden block. Then her hands slowly trickle down the bare body, teasing her nipples a bit along the way down to THE slit. Pushing herself in between Yuna, she spread her legs and strapped them tightly to the 'handles', immobilizing the thighs and ankles. Yuna lay there helpless. There is no way she could ever close her legs. Mikki bent down with eyes directly in front of Yuna's clean shiny waxed pussy. Mikki got more to just teasing her sister there. She unlatched a catch and Yuna screamed. 'Mr Y' just sprang and stretched her legs wider to almost 180 degrees - the widest and the first for Yuna for usually she is on 150 degrees spread eagle.

The pain from the suddenly stretch shot up her brain, the tension at the crotch is obvious. Mikki could see the muscles trying to pull the thighs back in vain and the slit cramp inwards. Mikki's tongue is restless by now. Moving in, Mikki ravage her sis's clitoris with rapid movement. Up, down, left, right, in, out... randomly and fast, sending Yuna screaming in ecstasy, twitching her body everywhere trying to relief the pleasure she was receiving from her sister...and then, squirt. the first wave was over. Mikki face was wet and she wanted to get her 'revenge' on her sis for not warning her. Yuna was still panting from the sudden tongue attack by her sister and catching her breath....

Mikki stood up, wiped her face and went to the fridge to get Yuna's favorite dildo - The Iceman. There on the plate lay the 7 inch long and 1.5inch thick dildo, totally made up of ice with a little handle frozen into it. Mikki grab it and walked back to Yuna who was still panting... not knowing her favorite dessert was going to be served....

Once again... Mikki love to play rough today. The Iceman locked on its target and fired itself into the tight wet cave... Mikki had started what Yuna was truly addicted to - The pleasurable pain and rapid change in temperature in her love hole... Mikki arms were train in that way.. well toned biceps through moving the ice in and out of Yuna on the right, while the left fingers twisted and pulled her sister's nipples....Each time the dildo went in... water squirted out from the melting of the ice as well as the juice from Yuna's red pussy... in no time, the Iceman was reduced to a mere 3 inch length and .25 inch thick... Yuna's pussy was totally ravaged, red and wet. Extremely sensitive to touch....

"Sis... thanks.. I think I have enough.. totally exhausted..." Yuna whispered with her eyes closed...

Suddenly Yuna felt a pair of strong hands on her breasts, rubbing and teasing her also red nipples... getting her aroused again... she smiled.

"Hi Daddy,' Yuna greeted, with her eyes still closed.

"Good girl, enjoyed what your sis did to you?" Dad asked but look at Mikki.

Mikki shaked her head not wanting to have what's coming next. After all, she is also naked in front of daddy and had guessed what will be coming.

Jackel unstrapped his daughter, helping her up and whispered to her ears, "Why not return the favor to your sis?"

Yuna look up and giggled in a very girly manner and turned to Mikki,"Why not?"
