Make her masturbate again

Stephanie grinned. "Well, Rach - if you won't share the recording ..." Mackenzie started to have a bad feeling about this. "What if she does it again for us?" Silence fell and the redhead felt like she was going to sink through the chair, and the floor. The other girls cheered the idea enthusiastically. "Well, why not, indeed. She would do anything to please us, don't you, Kenz?" Rachel's voice was biting and sarcastic. Mackenzie looked up, helpless. "Rach, please..." "Shut up."

She didn't get to stare for too long, before Rachel pulled her hair. "Get busy, Kenz." Mackenzie flushed as she timidly slid her hand between her thighs, touching her labia, still slippery after her climax on the deck. Much to her horror, the thought of masturbating in front of the girls was both embarrassing and exhilarating. She began caressing her mound, and her fingers slipped under her hood, finding the engorging clit. Mackenzie closed her eyes as she began masturbating in earnest, her nipples stiffening painfully as the arousal started spreading across the body. Her skin started feeling almost electric.

"Wow, she's so into it!" With her eyes closed, and entirely entranced, Mackenzie couldn't tell who girl said it, but the words made her feel even more humiliated and, surprisingly again, even more aroused. She felt her hair tugged and heard Rachel's soft voice in her ear. "Spread your legs wider, Kenz". The redhead moaned and complied, curling the index and middle of her right hand. She parted her labia and slid them inside her pussy and began rubbing her clit with her other hand, feeling the soft, wet touch of her walls on her fingers while her fingers moved in and out.

Mackenzie began panting as she felt her juices flow over her fingers. Her nipples were rock hard, and she felt ready to explode for a second time. Already primed from the first masturbation session, she came hard, crying loudly and squirting on chair and on the coffee table, and it was only Rachel's tug at her hair that kept her from losing balance and fall off the chair when she almost passed out in the throes of her quivering orgasm.

"Wow." The room became silent. The girls had treated this simply as an amusement at first. By the time Mackenzie came, the mood had changed a lot. They were aroused now too. Very aroused. It was inevitable that this led to something else.
