Finding Out

When I found out my younger brother had such a large penis, I couldn't stop thinking about him and it.
I basically caught him having sex with a friend of mine, when our parents were revamping their restaurant during the last break in lockdown.
I watched them fucking for a good five minutes before I let them know I was there.
My friend was so apologetic, but by then I had only one thing on my mind.
Telling her to go with my brother trying to make excuses, she walked out ten minutes later after I said ill ring her that night.
Returning to the lounge where they'd been having sex, I saw my brother putting on his boxers.
In my mind it was then or never.
Shouting at him to remove his underwear, he did as I ordered and watched as I removed my clothing. The look on his face as he took in my nakedness was just wonderful.
Not wasting any time. I walked over straddled my brother as he sat upright in the couch. Pressed his face to my breasts and began rubbing my pussy all over his hardening cock.
He didn't respond at first, probably still shocked it was happening. But once I felt his erection rubbing hard against my clit, and I began to moan a little, he started to kiss and suck on my nipples.
Reaching back, I guided my brothers enormous cock into my pussy and didn't stop riding him frantically, until I'd orgasmed three times and he'd cum deep inside my love tube.
Once I'd calmed down a little from him cumming, which made me orgasm the third time, my younger brother lifted, then moved me so I was on my back.
Sliding down my body, without me asking him to, he got between my legs and began to tongue my pussy and clit.
I knew he'd be tasting and eating his own cum, but I somehow doubted it was the first time he'd swallowed his own juice.
Making me orgasm once more, he then moved up so we were face to face, and kissed me.
As he did, my brother entered me again. Only when he fucked me, it was long slow rhythmical thrusts as we carried on fucking.
Every movement into my body was so beautiful, so sexually right, I didn't want him or it to stop. And when I climaxed almost biting his lip as I did, he quickened his thrusts making my orgasm extremely intense.
Pulling out of my pussy, he tossed himself off a few times, then came all over my breasts.
When our parents got back home, we were both sat on the same sofa my brother had earlier fucked me on.
We'd showered together by then and stood kissing as we washed each other. And it was in the shower I told my younger brother, his body, cock and love were mine from then on.
Now two years on, he's nineteen, I'm twenty and there's not a day that goes by where we're not having sex.
My brother does have another sexual friend. But that person is in his thirties and fucks my younger brother.
