She can't behave

Her fingers wandered under the waistband of her skirt and into her panties.

She immediately inserted two fingers into her wet vagina and began to rub herself. After less than three minutes, she had a breathtaking orgasm. Panting heavily, she collapsed into the chair. "Oh man, something like that shouldn't happen to me in front of her—or should it?" she thought to herself, trying to push the thought away.

Tomorrow was an important day for her. She only had a day and a half to properly prepare the cabin for her friend. Since she wanted to leave early the next morning, she went to bed.

She took off her top and bra. She critically examined her breasts in the mirror. She so desperately wanted bigger breasts, but she also knew that would probably always remain a dream. With a teasing grin, she thought of Simone's (her best friend) sexy C-cup breasts. She loved kissing her friend's breasts so much.

Now she stepped out of her skirt and shamefacedly observed her damp panties. "Bad girl," she thought, and slapped herself on the bottom. Then she took off her panties and lay down in bed. After another loud orgasm, she fell asleep peacefully.

The next morning, she dragged herself out of bed early. With an excited grin, she saw the still slightly damp pussy left behind by her orgasm the night before. "You'll never learn!" went through her mind. As punishment, another slap on the bottom followed.
