Being pressured into marriage by his live-in girlfriend Ruka, he tries to calm her down—accidentally brushing his hand against her breasts. Seizing the moment, he boldly grabs her massive tits, kneading them as he hears her sultry whisper, "You're not getting off that easy... Ahn..." Unable to resist, he lifts her T-shirt and starts fondling her bare breasts, teasing her hardened nipples with his fingertips. Before he knows it, Ruka smashes his face into her cleavage with a sudden titfuck counterattack, declaring, "We were still talking... Ei!" All arguments forgotten, they plunge into passionate couple mode. As she wraps her hands around his rock-hard cock, she shyly mutters, "Jeez... you're already so hard..." yet proceeds to lavish him with deep, skillful blowjobs and exquisite titty fucks. Just as she teasingly says in a mischievous tone, "Maybe I'll stop here for today!" and tries to deny him release, he forcefully pulls her close and thrusts into her from behind. A love-drunk, pleasure-obsessed couple indulging in relentless, passionate sex filled with massive-tit titfucking.
