One night Nicky one of these woman came up with a bet for Kat her sister was coming for two weeks and she said no matter how Kat tried she could not g...t her! Now Kat didn't want to take the bet but was pressured into it so she says OK but if no when I win you are my sex slave for a month. Nicky agrees then she tells Kat that her sister is a sister of St. Anthonys Kat says so and we drink the night away. Friday night at the bowling alley Nicky brings her sister in ( dressed in a 50'ish. Shep allowed himself to be led, and as Bennie let him out the back door he saw that the big dog was showing signs of being sleepy again, heading directly for his dog house several feet away.Bennie's boyish face and body were flushed with excitement as he rushed back to his waiting brother and stepmother.Inside, Carolyn lay in a semi-swoon upon the floor, anguished thoughts and feelings mingling with the strange sensations that the boys' special potion had aroused within her. Just as she was. These doubts did not come from any type of religious guilt or anything like that, but just a nagging feeling.

Her smooth outer pussy-lips and asshole were momentarily flashed in my direction. I suspected that she'd done it for my benefit. A quick cheeky-smiling glance from her back at me seemed to confirm my suspicion. I smiled, my dick expanding quickly in my shorts, and hoped rather.
