Two beauticians from a famous brand, Ms. Sakamoto and Ms. Aoki, take on a challenge: if they can make a man cum four times within 30 minutes, they win a cash prize. A plain-looking guy is brought in, and immediately the two women lift their blouses to flash their bras, then hike up their skirts to reveal black pantyhose-covered panties. The T-back peeking through the sheer black stockings is incredibly erotic. At first things are soft—both women start giving full-body lip teasing, quickly pulling out the cock for a double blowjob. They then remove their panties, exposing their bare pussies. When both pussies are fingered at the same time, they both squirt simultaneously! Their cunts are soaked and aroused, getting so turned on they even kiss each other. Stimulated with fingering and cunnilingus, they climax repeatedly, grinding their hips. The bolder senior woman then takes the cock into her mouth and starts violently headbanging—unable to hold back, the first cumshot erupts, and she swallows it all. With time running short, a second plain guy is brought in. While receiving a double blowjob, they work to achieve the remaining three loads. The cock handled by Sakamoto shoots its load first. When the other cock refuses to cum, they flash their bare breasts to boost arousal. Finally, through double handjob, the third cumshot is achieved! Just as they think another load is possible, Aoki keeps jerking him off intensely—when suddenly, instead of semen, a massive cumshot of male juices sprays out, forcing them to dodge frantically, almost comically overwhelmed. The cumshot resembles a broken sprinkler, gushing endlessly! Time is nearly up! Whether driven by the prize or pure lust, the senior girl asks her junior, "Hey, don't you want to take this cock inside you?" The junior eagerly responds, "Yes, I want it!" The senior gets on all fours, thrusting her ass out, begging for penetration—her pussy is impaled with a bare cock! She starts slamming herself onto it, moaning in excitement, "Cum inside me!" while her junior partner supports her with passionate kissing. Joyfully, the fourth creampie cumshot is achieved! When the cock is pulled out, semen drips out as her pussy makes loud "blub blub blub blub" farting sounds. The condition is met, but the junior, left unsatisfied from not being penetrated, and the out-of-control plain guy start going at it on their own. The senior lines up beside her junior as the man pistons in and fingers the other pussy, double-penetrating both holes, eventually giving the junior a creampie too! The junior’s pussy overflows with semen, and the senior, wildly excited, starts licking it clean—her junior is slightly shocked and taken aback. The senior’s frenzy doesn’t stop—she mounts the guy in cowgirl position, frantically grinding her hips toward orgasm, climaxing with intense, pounding thrusts like a nail being hammered. The unsatisfied junior then straddles the guy’s face, starting a reverse cowgirl face ride! After the senior finishes, she hands over the cock to her junior, who now rides passionately, desperately grinding her hips toward climax. Then switching to missionary, the senior spreads her legs wide, her slutty side fully exposed as the bare cock rams into her pussy, thrusting wildly. "Ah, so good! Fuck me harder! Fill me up, cum inside me!" she screams, unleashing her full slutty eroticism—another creampie! Seeing her junior watching longingly, they finally stuff the cock into her lonely pussy too. She spreads her legs wide, feeling intense pleasure, and climaxes with her fourth creampie! Handjobs, blowjobs, and creampie sex lead to a total of six cumshots! Still aroused, the two women start masturbating with the creampie semen, and seeing this, the plain guy’s cock revives. The senior takes one final deep thrust into her pussy for an extra creampie, getting pounded to multiple orgasms, before the cock finishes with bonus semen shots into both of their mouths!
