She craved love and affection, yes, but most of all she craved a good screwing. Mary and Danny were her outlet for love, but was tired of fingers in her lonely bed. She decided to phone Judy later and have a serious discussion about her future.

Outside the Lasky house, Mary squealed, and Danny hurried to his sister's side.

"What's the matter?" he asked, pushing Blackie aside. The dog was sniffing Mary's legs and yipping playfully.

"Oh, just his old cold nose," Mary complained. "He got behind me and pushed it against my leg and it felt like an ice cube!"

She turned to leave when the dog shoved his big head under her skirt and prodded the bottom of her ass with his wet nose.

"Eeek," Mary squealed again, then giggled and rubbed herself through her skirt. The sudden contact had startled her, but she knew it was her own fault for not wearing panties. As she jumped away, Blackie thought she was playing and he tried to worm his snout under her skirt.

Danny watched, then pulled the dog away. "You must smell like dog food," he teased.

Mary turned angrily and just then Blackie lunged and broke from Danny's grip.

"Yow," Mary cried, rubbing herself again. "He nipped me!"

She backed away a few yards and Danny followed. "Gee, he didn't leave a mark, did he?" she asked, lifting her skirt to her waist and sticking out her cute ass. She looked at it over her shoulder, then looked sideways at Danny.

"Wow, what an ass, Sis!" Danny breathed, admiring her tight, quivering, snow-white cheeks. "Are you askin' for what I think?"

Mary didn't answer, but she kept her skirt up and breathed harder. She knew what she was doing was dangerous, but she was feeling awfully horny these days, and she was curious, like all young girls, about what boys are like. And Danny was the nearest boy.
