My Brother, My Knight

His cock looked huge. The knob end was the size of an apple. He was hard as steele as he pushed his way in. I felt every ridge of his cock as it gained ground in my welcoming tunnel. I thought it was going to come out my mouth, it went so deep.

I knew then, this is what I really wanted all along. David was my prince. Always had been. Now I was his princess. He took his time, claiming my entire body. He fucked me to my first orgasm caused by a cock. And my second, and my third. By then it was a continuous wave of pleasure. He knew just when to speed up and when to slow down. Long strokes, short strokes. Never ending ride of bliss. I begged him to cum in me. I wanted his cum. I even wished I wasn't on the pill. I wanted to make it complete. The way it should be. Cock and pussy. Sperm and egg. The whole picture.

He blasted my insides and I was exhausted. Every muscle in my body had tensed up, suddenly relaxed. I lay on that floor, arms and legs limp. I felt David withdraw his spent cock. I couldn't move.

I didn't hear Grandpa come in, but I heard him say "You did good son. That's how a woman is supposed to look after a fuck. If I were a bit younger, I'd give her a ride myself."

"No, 'fraid not Grandpa. This one's mine." David said.

We sat and cuddled for a while and then David fucked me senseless again, before we left. I know Grandpa was watching through his slightly open bedroom door.

We spent the rest of that summer visiting Grandpa several times a week. We often got alone time at home too.

I didn't go looking for other cocks after all. I had found the one I wanted.

When school started in the fall, David and I shared a two bedroom apartment, though we only needed to wash one set of sheets. To the outside world, we're just a brother and sister sharing an apartment.

David is a senior now, and I'm a junior. He has decided to get his Master's degree, which will take a while. I might decide to also. Guess we will have to keep sharing an apartment.
