S1 x TAMEIKE’s 20th-anniversary collab! Saki Okuda plays the seductive married sister-in-law who lures you into a sweltering countryside affair. Her glistening, sweat-soaked curves cling tight as raw, relentless thrusts send her climaxing again and again—ending in a messy creampie flood. This uncensored one-on-one captures the taboo heat and dripping intensity of forbidden summer lust.
