Koizumi Yuuka Chan challenges a popular Series "Geki piston" counting the number of times that I attacked in FUCK! Counting keeps on forgetting the number of times in a piston pleasant feeling although I begin it, and panting by oneself! Be Squirting in Vibrator torture & Fingering! Keep back riding on horseback being made, and waving a waist to Bach by oneself, and living! The piston total number exceeds 20,000 times at last, and the product is the special volume now!
