Good friends Nako and Kaho chat candidly, sharing their recent happenings. Nako is curious about the vibrator Kaho used the other day when she had sex with her senior. Out of curiosity, they decide to try it out, and as they start playing with each other’s pussies, they start to feel strange. Then, the senior comes over to their house with a male friend. The four of them spend their time chatting about trivial things, but the two are already horny and can’t resist the men’s perverted advances… Before they know it, their panties are pulled down, and they’re being made to moan with the vibrator and fingering, leading to a brutal orgy. Seeing their female friend next to them getting pleasure from it makes them even more excited! Seeing their female friend’s insertion point right in front of them makes them forget their shame and moan to the max. They swap dicks, share pussy juice, and end up with a massive creampie… Nako and Kaho are such good friends that foursomes seem like they’ll become addicted to it.
