24-year-old pure-hearted main girlfriend, Aki Sanjo, has remained a lasting presence in her boyfriend's heart throughout their four-year relationship. A well-mannered, popular young lady from a good family, she hides a deeply intense sexual desire beneath her innocent exterior—an exhibitionist pervert who craves creampie sex, cum drinking, and piss drinking. Her blowjob skills are top-tier, especially her deep-throat technique, which deserves to be seen. She's particularly obsessed with thick, large cocks, and drawn by that appeal, she's now diving into her first-ever NTR experience. Recently, her boyfriend has been arranging encounters with well-endowed men to enjoy cuckolding. This private video captures Aki's very first cuckolding session, entirely self-recorded. Her partner is Ken-chan, a 48-year-old man the boyfriend met at a host bar he occasionally visits. Aki took a liking to Ken-chan and personally set the date for the encounter. On the day of the play, the boyfriend's penis is already erect before entering the hotel. Once all three arrive, the action begins. First, Aki deepthroats Ken-chan's thick cock. Watching his girlfriend suck another man's dick for the first time, the boyfriend feels not just jealousy but overwhelming arousal. Next, switching positions, Ken-chan mounts Aki and thrusts his cock into her wet pussy. Her lower half is soaked—this is her first time taking another man's cock. Aki insists on a condom ("No bareback, it's my first time"), which Ken-chan politely agrees to. Then, Aki herself guides Ken-chan's fully erect cock inside and slowly grinds her hips, savoring the sensation of a stranger's dick. The boyfriend, filming the scene, is rock-hard. Next, Ken-chan grabs her hips from behind in doggystyle, pounding her fiercely, sparking jealousy. Aki's moans grow louder. Finally, in missionary position, Ken-chan thrusts deeply into her. Aki cries out, "It hits so deep—so good!" Watching them passionately fuck like lovers, the boyfriend is on the verge of cumming. When Ken-chan is about to climax, Aki pleads, "Cum in my mouth! Let me drink it all!" The boyfriend loses it—jealousy and arousal driving him insane. As Ken-chan pulls out, Aki quickly removes the condom and takes the thick stream of hot cum straight into her mouth, gulping it down eagerly. After the scene ends and Ken-chan heads into the shower, the boyfriend can't hold back—he fucks Aki himself and fills her with his own creampie. Enjoy the filthy, lustful sight of your depraved girlfriend Aki.
