Rabella returned home from work and soon wondered where Simon was. Checking her handheld computer for messages, she read Simon's terse email. "Vagina?... Vagina?! Are we in Health Class, Shelly? God, you needed this lesson more than I thought!" Michelle flinched as Linda cupped her crotch with one hand. "You're going to call this your pussy or your cunt from now on, understand? Do you want me to fuck your cunt?"Michelle hesitated only slightly. "Y-yes. Fuck my cunt."Linda helped Michelle strip out of the rest of her clothes, then took one of the ropes that had been used for the hogtie and tied her sister's hands behind her back,. She was walking around on her own, looking in the shop windows, killing time, and I just started following her.“She was quite small, about five feet two or so, blonde, and very lightly built. I suppose I knew I’d be able to overpower her easily. She was very cute and sexy without knowing it, like she’d never done any sex but when she did it would really hit her.“She had these great eyes, big and very light green, and she was wearing short shorts and a short t-shirt. You could see her tummy. It. They were very soft and a handful.I was so engrossed that I didn’t realize I was still caressing them after regaining her balance. “Uh-uh,” she said. I quickly got back to my senses and apologized. “Don’t worry, quite a few girls have fallen for them,” she said. So I knew she was bisexual, and that excited me.I was starting to get horny now. We went to our rooms and parted with a hug. She hugged me very tightly and pressed my ass. After breaking the hug, she winked at me and kissed me.
