My mom caught me trying on her panties.I didn't know what to say.

"Why are you wearing my underwear?" she asked.

I said, "Oh, I... um..." She was sitting at the kitchen table and looked so beautiful in a summer dress that I couldn't think of anything else to say. And then it came out: "They just fit better than my own."

She laughed. "Well," she said, "You can wear them anytime you want. Just leave some for me. Or..."

"Or?" I asked.

"Or if you wear the sexy new ones, they're for your dad, so you might have to display them for him.

I didn't think about it until a few weeks later, when she had new panties. I put them on. They were soft and silky and felt wonderful against my skin. As soon as she saw me in them, she smiled. Then she gave me a kiss and told me how much she liked the new ones.

"But those are for you dad," she whispered.

I don't know why, but my cock got hard.

"Better go show your dad," she said.

That night, he came into the bedroom while I was masturbating. He'd been drinking and his eyes were red.

He grabbed my arm and pulled me up onto the bed with him. His hand went down between my legs and began rubbing my ass through the thin panties.

"Your mom says you've been wearing her panties," he said.

"Yes," I said, shyly.

He said, "I like these. Very sexy."

Then he added, "And they must be making you horny."

As he spoke, I could feel his fingers rubbing my cock through the silky material.

"Dad," I said, "I'm your son..."

"So?" he replied.

"You shouldn't touch me this way," I protested.

"Why not?" he asked.

I was still embarrassed by being caught masturbating.

He said, "You wouldn't be wearing mommy's clothes if you didn't want daddy to touch you."

When he spoke those words, something inside me opened wide. It was all right to wear my mother's panties because that meant I wanted my father to see them. I moaned for him.

He bent forward and kissed me. He smelled of beer and cologne.

"Where do you like to be touched?" he asked.

"Anywhere you want dad," I couldn't help but say.

He said, "I'll show you where I like to touch."

His hands went over my ass and groped my cheeks. He pushed my head toward his crotch. My mouth found his stiff erection.

"Fuck me!" he cried.

I knelt there and took his throbbing member into my mouth. It was long and thick and tasted salty.

I held the base of his shaft and tried to fit more of him into my mouth. I loved to feel him slide back and forth across my tongue.

Suddenly, he stopped me. With both hands, he squeezed my cheeks. Then he pulled me off of him and stood up.

"I'm going to fuck your ass," he said.
