Part of the problem was that Heidi and her parents had just moved to town a few months ago, and so Heidi didn't have many friends. Brandi, on the other hand, was very popular, and had lots of friends. Heidi was glad that their moms had introduced them. They had become friends almost immediately. And Brandi had admitted to her that even with all the kids she knew at school, she'd never really had a best friend. And from that point on, best friends they'd been. Heidi still hadn't gotten to know many of Brandi's other friends very well (she was something of a shy girl), but that didn't matter, not as long as she was friends with Brandi.

"Well, here's my stop," Brandi said when they reached the walkway to her house.

"Okay," Heidi said. "Are we still getting together tomorrow?"

"Oh, I'm afraid I can't," Brandi replied. "I've got something planned. With the family and all. How about Sunday?"

"All right. See you Sunday!"

Heidi waved to her friend as the blonde girl walked down the pathway to her house, then continued walking to her own house, which was just a few doors down. When she reached her house, she very quietly entered through the back door, gently closing the door and tiptoeing into the kitchen, where she carefully set her book bag on the kitchen table, trying her best not to make a sound. Her mom didn't know she was coming home early, and she thought it would be fun to surprise her. No one was in the kitchen, but she heard noises coming from the living room, so she tiptoed in that direction. When she entered the living room, she stopped dead in her tracks, her eyes wide with shock.

Her mother was sprawled out on the couch, and she was completely naked! And even more shocking, the paper boy was lying on top of her, and he was naked, too! Heidi simply stood and stared. The paper boy was thrusting his hips against her mother's, his ass cheeks tightening every time he drove forward. He was kissing and sucking on her mother's neck, while she ran her fingernails down his back, moaning and gasping. Heidi had never actually seen it before, but she knew what they were doing - they were fucking! Her own mother was fucking the paper boy while her father was out of town on business. She couldn't believe it. Her emotions were in an uproar. She was upset and hurt that her mom was cheating on her dad, but at the same time she was strangely excited at actually seeing two people having sex. She felt kind of tingly all over, especially down between her legs.

Heidi stood there, quietly watching her mother getting fucked. Her eyes were especially drawn to the naked body of the teenage paper boy. He was slim, but well-muscled, with a deep tan over all of his body except for his white ass. His ass cheeks were tight and firm, his legs long and muscular. She had always thought he was cute; now she was seeing him in a whole new way. She was also seeing her mother in an entirely new way. She knew that her parents still had sex pretty often (even if they tried to hide it from her - they still made a fair amount of noise when they thought she was asleep), but she had never really pictured them actually doing it. She stared at her mother's face. Her eyes were closed tight, her mouth part way open. She was moaning continually.

Almost by itself, Heidi's hand moved to her crotch, and she started to rub slowly at her pussy mound. The tingling sensation between her legs intensified as she rubbed herself, and she had to bite her lower lip to keep from letting out an audible groan. Her legs spread apart slightly so she could slide her fingers lower down, her fingertips sliding along her pussy slit. Even through the material of her panties and skirt, it felt nice - exciting, and at the same time, very naughty. Brandi had told her one time about how she had played with her pussy, and how good it had felt, but Heidi had never tried it. She had been curious, but had never had the nerve to actually do it.

"Oh God, Tommy," Heidi's mom shouted. "That's it. Fuck me! Fuck me so good!"

"Mrs. Swaine, your pussy feels great!" Tommy gasped. "I swear, you're the best fuck on the block!"

"That's so sweet," Heidi's mother replied. "I bet you say that to all the women."

All talking ceased as Tommy pressed his lips to Heidi's mom's. They kissed passionately, hungrily. Heidi had never seen anyone kiss like that before. She watched intently, eager to see every detail. She stared as their lips parted, their tongues coming out of their mouths, twisting around each other, each taking turns pushing their tongue into the other's mouth. When their kiss finally broke apart, Tommy moved his lips along her jawline to her neck, where he started sucking on her, his lips firmly attached to her skin. Heidi's mom quickly pushed his head away.

"You want my husband to see that?" she asked, obviously annoyed.....(cont)
