"Hmm, you're quite a bit taller than the last girl. You're what, five foot ten?" I asked."Five eleven, actually," she replied proudly, as if she had a...y control over her height."Nice," commented as I felt my gift lengthening the table to fit her perfectly."Now, for the test, do you want to be standing up or lying down?" Which one hurts less?" This is a test, not a spa treatment, but my gift will ensure that each one hurts equally if it makes any difference." Great," she sighed, chewing her lip.. My sister's head snapped around and she stared into the gloom. I wasn't sure if she could see me but a mischievous smile crossed her face and she kept staring out in my general direction. She lifted the front of her bridesmaid dress. Her long legs clad in the black gossamer nylon stockings contrasted nicely with the pink taffeta dress and her creamy white thighs.Between her legs the V of her white satin panties seemed to glow in the dark. She rubbed the front panel of her panties and then she. It was the most exquisite feeling I had ever had to have her soft lips moving up and down my cock. "MMMMMMMMM" she groaned as she bobbed up and down on my cock, reaching down to fondle my balls with her free hand.I looked up to see the glory of her squirming ass and wet pussy. I reached up and parted her cunt lips and began to lick inside. Eventually I focused my attention on licking and flicking my tongue on her pulsating clit. My sister's moans began to increase in intensity, indicating her. Already I’ve missed three weeks of classes. And I asked to two or three people but none gave good response.Finally I approached to her for the same, she immediately responded by giving some notes to copy at my home. I copied three subjects for three days, and fourth day am unable to write even in class dictations. She found that my fingers are completely turned to green with some irregular shape. Then she immediately scolded like anything and took all my empty notes with her without any reason..
