Surprised by my own horniness, thinking about sex every single day, I went through a strict 30-day period of abstinence with An Hinohara, an insatiable older sister. Due to extreme deprivation, my entire body's sensitivity heightened abnormally, causing sexual desire to explode uncontrollably. Through relentless teasing and prolonged denial, my arousal was pushed to the absolute limit, leading to an intense, relentless barrage of fucking. Each thrust in and out made me squirt urine with a splashing sound, while my hypersensitive pussy received even more stimulation, amplifying the sensation of her violent piston pounding. Overloaded with repeated orgasms, my consciousness gradually faded, brought to the brink of passing out—this is an outrageously intense experience.
