The redhead reached down and undid the tie of her robe, letting it fall open. She looked down to where her carefully painted fingers were working over her pussy, stroking inside, tickling her clitoris… and she groaned softly. It was perverted, but she was so damned excited!
Her fingers flew in and out of her pussy as the passion-tingles became more and more overpowering. Her orgasm hung just a few seconds away, waiting for just the right touch.
"Aaagghhh! Jee-zuz, Jake honey! I'm cumming again! I'm cummming!"
The brunette pound her ass energetically down against his hips with as much abandon as his firm grip would allow her. The clinging spasms of her cunt seemed to be more than Jake could take. He couldn't hold on any longer.
"Ahh, shit! Me, too! Baby, I'm cumming!" He thrust his powerful loins up against her until the last drops of his sperm were deposited far inside her cunt.
Watching the others cum so rousingly was the final straw for Heather. She was cumming, too. Her robe flapping carelessly about her, she writhed out her orgasm on her fingers. She hung her head in unseeing ecstasy for a moment, then she took another peek through the fence. Jake set Rita back down on the ground and held her in his arms for a long quiet rest from their mutual ecstasy. He hadn't even had time to put his cock back in his pants when the back door opened and Linda came out into the yard.
Heather's heart leaped to her throat as she watched the blonde approach the adulterous couple. She felt she shared their guilt. After all, she had cum, too, watching them enjoy their illicit fuck. She felt she had betrayed her best friend.
Much to her surprise, Linda did not seem the least bit perturbed. Instead of shouting threats and accusations, instead of bursting into tears, she threw an arm around her husband and his lover and kissed each of them on the cheek.
"We thought you guys would never finish out here." Her voice was cheerful. She was definitely not upset.
"Well, you know Rita and I always get a little carried away."
Linda reached up and ruffled her husband's hair playfully. "Well, why don't you come inside and get carried away? We need your inspiration."
Heather's mouth was still hanging open as she watched the three of them walk back to the house. Rita was in the middle, still naked.
As she lay sleepless that night, next to her snoring husband, Heather searched her mind for some explanation of the strange events she had just witnessed in her neighbors' garden.
But any explanation seemed even stranger than what she had seen.
