Five years ago, my cute cousin came to Tokyo and stayed over at my place. She's already 20, so maybe it's okay to make a move? When I saw her again after so long, she had transformed into a brunette delinquent-style girl. Coming from the countryside, she arrived dressed with a tough, delinquent flair. Along with her female friend from the same group, a scary-looking blonde guy showed up too. They helped themselves to beer from my fridge, stripped down to near-nudity because they were hot, and smoked cigarettes despite me saying no smoking, doing whatever they wanted in my apartment. The blonde guy and my busty friend started having sex on my bed without hesitation. Their loud moans made it obvious what they were doing. Hearing those sounds got me extremely turned on. Without thinking, I told my cousin I wanted her, and she carelessly replied, "If you want it, just do it." Guess there's no choice but to take her!
