Frustratingly

As Margaret bathed, Natalie had sneaked into her sister's room. After rooting around in Margaret's drawers, she finally came across a beige vibrator.

"I knew it," she whispered. She wondered how humiliated Margaret would be if she knew her sister found it. She took the vibrator and rubbed it down with a mouth-numbing gel, "Good luck getting off tonight, sis," she whispered as she slipped the vibrator back into its hiding spot.

Later, Margaret came out wrapped in a bathrobe. "I have some herbal tea for you," said Natalie. She pointed to a mug of steaming tea on the kitchen bar.

"Oh, uh, thanks, Nat." Margaret went and took the tea and went into her room. She sat on her bed with a sheaf of essays to grade. Any time she came across a boy's essay, she thought about his cock, and soon became too distracted and frustrated in herself to continue. She finished her tea and tried to distract herself by reading, but she kept thinking about sex. She finally gave in. She crept to her door and quietly locked it. She went to her dresser and got out her vibrator. Any time she used her vibrator, she felt naughty and a bit ashamed, but she took her robe off and slid under the covers. She turned the vibrator on and started teasing herself by gently probing her pussy lips with it before she slid it in and started fucking herself with it.

It took a couple of minutes for Margaret to know something was wrong. Despite her best efforts, not only could she not get herself off, but she was not even stimulating herself. She grew more and more frustrated as she needed to get off, but she could not even come close to getting off. She was growing sweaty and panting, but it was in frustration more than sexual arousal. After a half an hour of frustration, which to her had felt like an eternity, she finally gave up and threw the vibrator down on her bed. She crossed her arms in a huff.

After a night of tossing and turning and barely getting any sleep while thinking about sex, morning finally came, and Margaret got up.
