Four adult classmates have turned my apartment into their regular hangout, and then they discover my secret porn collection. They tease me for owning so many uniform videos, and I think my life is over—only to find myself in a harem. Tied up and treated to four wet, intense blowjobs, I lose both reason and restraint. They apparently love my cock, because that day marks the start of nonstop sex at my place. Cheerful Rikka Ono, adorably different-at-home Ichika Matsumoto, sweet and affectionate Sana Mashiro, and serious, elegant Nana Yagi all push out their pussies and ask me to fuck them. With four unattainable beauties inviting me at once, a wildly happy round-robin harem begins.
