Older Sister

I was at home, alone I thought, and started jerking off looking at a magazine of girls.
My sister walked in and caught me masturbating.
"What are you doing?" she said. I recoiled in embarrassment.

"It's okay," she said. "Everybody does it. What are you looking at?"

I showed her the mag.

"Do you like girls like that?" She asked. "How about me? Can you masturbate looking at me?"

My sister unbuttoned her blouse and exposed herself in her bra to me.

"Really," I asked in surprise.

"I had a boyfriend who liked to jerk off in front of me, so I'm used to it."

I resumed stimulating myself and looked at my sister's breasts in her bra. She removed it. I was so excited.

My sister let me touch her breast and we kissed. She took hold of my penis and started pulling it. I undid her pants.

Suddenly, we were naked, and I went down on my sister. I licked her pussy and got her wet.

"Put it in me," she said.

"Let me put a condom on," I replied.

"It's okay, I'm on the pill."

I slid my dick in my sister's vagina. We moved slowly. Gradually we moved faster. I put my finger on my sister's clit and masturbated her. We moaned together for a long time.

"Did you cum?" I asked her. "Yes," my sister said.

"May I cum?" I asked. "Yes, do."

I pumped my sister harder than I had before. She held me tightly and her legs were spread wide. My forehead was against hers. We stared at each other and made distorted faces. I ejaculated in my sister's pussy with no condom. We convulsed.

After resting a while, I put my underwear under my sister in order to catch the jism so there'd be no wet spot.

"Why are you on the pill," I asked.

"Sometimes I fuck and maybe with my younger brother."
