During a long university break, college students Ryu and Haruki found themselves with too much free time. Before heading to a hot spring facility where swimsuits were allowed, they decided to try on their swimwear first. From there, their time together gradually grew warmer and more tense, building excitement between them until it reached its peak. Soaking in the tub, they escalated into an erotic kiss while jerking each other's erect cocks. After fooling around, they moved to the bedroom, their relationship already shifting from friends to something more like lovers. Ryu passionately sucked Haruki's huge cock spilling out from his tight athletic briefs. With little foreplay, Haruki thrust his massive dick deep into Ryu's ass for intense, full-contact sex. Though they had started as just friends, the two had unknowingly evolved into a couple. Exposing their lustful expressions, they shared the most exhilarating experience together.
