I am an adult college student with a long-distance girlfriend. We are so close that we call at the same time every day, and I assume we will eventually marry. Only days later, everything changes at a welcome party held at the home of Kaoru Yasui, the most beautiful senior in our club. My classmates quickly pass out drunk, and so do I. When an intense sensation in my crotch wakes me, I rub my sleepy eyes and discover Yasui with my cock in her mouth. She then urges me into bareback sex, and I spend my college days fucking her until I am completely hooked.
