Shelly's Incentive

Horny as hell, Shelly pulled the long purple dildo from her mouth and threw it across the room. It wasn't working. She had suspected that it wouldn't, but with John not home, she had to try something.

It wasn't just the sucking. When she had closed her eyes and pretended it was her brother's penis, the sucking had felt great. But Shelly's imagination could only take her so far. Her senses constantly reminded her that the dildo was a cheap imitation. Absent was the deep, musky smell of her brother's groin, the heat of his skin, his fingers in her hair.

And the cum.

Oh how she craved the cum.

And not only the taste. The feel of it spraying into her mouth, filling her up, almost bringing her to gag. It it was only the taste she would ask John to save some for her in a jar that she could drink at her leisure. No, it was the entire experience she wanted, and as Shelly dropped her hand from her sloppy vagina, leaving her unsatisfied, she knew she would have to wait for it.

The sound of the front door closing snapped her out of her funk. She jumped from her bed, pantless, ran to her bedroom door and poked her head out with excitement.

"John?" Shelly called out hopefully, but didn't receive an answer.

"Mom?" Shelly's voice carried a bit louder, but with the same result.

Had her mother gone out and left her alone? If only John was there to take advantage! She could maul him in the hallway, or in the bathroom, or in the living room! Damnit! Where was her brother?!

Closing her door, Shelly bent down and picked up her panties. They were damp, of course. She had spent too much time in expectation of her brother coming home. Putting them in the hamper, she grabbed another pair. Shelly would have to shop for some more soon, as she was going through underwear far too quickly since she and her brother had come to their new sexual understanding. Not that she would mind. It would be expensive, but she could picture John's face in her mind's eye when he saw his sister in sexy, lacy, revealing underthings. It would be worth it.

In her new underwear and t-shirt, she flopped back on her bed and picked up her phone.

_Where ARE you?! _she texted John's number as she absently rubbed herself through her panties. Then she got an idea. If John thought he had better things to do than come home, she'd just have to give him some incentive. Opening up her camera app, she began to get creative.
