When I met my girlfriend's younger sister for the first time, she was a beautiful girl with neat black hair. She was dazzling in her uniform, but her defenseless panties caught my eye, and I couldn't help but jerk off. I couldn't hold back my ejaculation and splashed it on her panties! I took advantage of the opportunity when my younger sister was confused by the sudden semen splash and inserted my dick! I made her cum over and over again with my continuous piston-like thrusts, without her asking for permission! I was addicted to her J-girl pussy, which was more sensitive than my sister's, and I splashed it on her panties and came inside her over and over again!
