My stepsister Saki loves me more than anyone in the world.
I could never tell her that I've actually gotten a girlfriend...
But one day, I couldn't help myself and was caught flirting with my girlfriend at home by Saki...
"Hmm, so big brother got a girlfriend... Well then, I'll just take all your firsts and make you so obsessed with me that you'll completely forget about her, lol."
"Big brother, you're a virgin, right? Let's practice for your girlfriend's sake?"
Pushed by Saki's aggressive advances, I ended up sharing my first kiss, first blowjob, and first sex with my own stepsister...
But this is just practice... so it's okay... it's okay... or so I thought...
Even while my drunk girlfriend slept right beside us, we had thrilling, immoral sex!
"Big brother! No! I'm cumming!!"
Before I knew it, I was captivated by my sister... I can't go back to my girlfriend anymore...
"Big brother, I love you so much! Let's be together forever!"
