Rachel dispenses with the picture excuse and fingers Mackenzie outright.

(Title by Bram Lueche, subject matter by shyexposure)

As much fun as Rachel was having with humiliating Mackenzie with pictures of her nudity, the concept of this was quickly growing old to her. She needed something new, something fresh, and it definitely had to humiliate the red head in the best way possible. Letting the pictures continue for a moment, and smiling when an adventurous guy grabbed Mackenzie's butt during the shot, Rachel wondered what she could get away with. It was in that moment, when the photos themselves were winding down that she had an idea.

It was a crazy idea, and if it backfired, she might very well be seen as a wrongful molester and outed from other social gatherings she might want to attend. But if it worked...! Not only would Mackenzie be truly humiliated, but if she was right and the girl's exposure was sort of a turn on to her, then she just might make her lose control another way.

Stepping up, she walked over to Mackenzie, who stiffened in embarrassed nervousness at her approach. The girl wasn't sure what Rachel planned, but she knew instinctively that it could not be good and prepared for it. However, nothing could prepare her, or those gathered around the nude girl, for what happened next.

"Mackie." Rachel called out sweetly as she approached Mackenzie. "This entire ordeal has been tough right? You need a way to let go of all this and put it behind you, don't you?"

Mackenzie wasn't sure what Rachel was getting at, but she had to admit she made sense. She wanted to get out of here, to get home, safe. And more importantly, get some relief. She wouldn't say it to anyone, but this ordeal had started another arousal to build inside her. If anyone found out, she'd be utterly humiliated. Still, Rachel needed and answer, so she gave a hesitant nod.

"Thought so!" Rachel sing-songed as she stopped in front of the nude girl. "Then let me help you ease some of those trussed up and tied nerves hmm?"

"Wh-what do you me--EEE!" squeaked Mackenzie as she felt something she obviously never expected.

Looking down, she saw that Rachel had blatantly slipped her hand between her thighs and was at this moment slowly stroking her clit. Mackenzie looked up in shock, then looked around, fearing the worst only to see she wasn't the only one. As the party goers looked on, Rachel rubbed, teased, and lightly pulled on Mackenzie's clit, before she slid her fingers further down.

"What are you d-doing?!" gasped Mackenzie as she tried to back away

It was found futile, as Rachel had easily sunk two fingers into Mackenzie's wet pussy and began to stroke in and out deeply.

"Why helping you relax of course. Isn't that right Debra?" Rachel looked aside at her friend

"Sure looks that way to me." Debra nodded grinning

Mackenzie for her part had mostly lost her voice, as Rachel's agile fingers found her sensitive spots inside her pussy and attacked them mercilessly with quick strokes. She couldn't take it much longer, and opening her eyes, she saw the blushing and sometimes aroused faces of everyone in her neighborhood watching the spectacle.

'Why aren't you helping?!' she thought frantically, before a particularly powerful surge of pleasure swept through her.

"Geez Mackenzie, if I didn't know better, I'd say you enjoyed getting fingered in public." Rachel taunted her

As if to torment her further, the harsh words sent another thrill through her body, and her pussy lips grew fuller and wetter, now dripping in small rivulets down her thighs. Rachels noticed this and grinned, then upped the tempo. She was going to have so much fun with this! As she curled her fingers, her nails hit a particularly rare spot, and Mackenzie screamed as her pussy gushed out onto the patio deck. Panting, then girl collapsed to the ground and shivered slightly.

"Well. I'd say that was a party and a half huh?" crowed Rachel

Most of the guests were dumbstruck, before a few started clapping, then a rousing cheer went through them all, despite a nude red head trying to hide herself again.

Mackenzie was mortified beyond words, realizing most people in her town had not only seen her naked, but witnessed her getting fingered to orgasm in public.

Sadly for our red head...
