LULU-184: My kind big-breasted sister couldn't stand seeing me dumped by my first girlfriend for premature ejaculation — from ultra-slow piston to high-speed hip-thrusting cowgirl tease training I couldn't endure and repeatedly came inside…!! Miu Arioka

About this work

After I was dumped by my girlfriend because of premature ejaculation, my compassionate big-breasted sister took matters into her own hands: she stripped down and ran PE-improvement training! Starting with very slow insertion and slow piston strokes to build me up, then switching to high-speed hip thrusts and stopping just before I came to tease me… but I couldn't hold back and repeatedly exploded inside her. From that day on it's daily ejaculate-control training! Can his premature ejaculation be cured by enduring the teasing cowgirl that suddenly switches from slow grinding to high-speed?
