Bong-Thom explores the forbidden in this yoga session gone wrong. A Japanese sister and brother, unaware of each other's presence, begin their daily routines. The sister, in a low-cut top and tight shorts, bends over, her ass in the air, unaware of her brother's growing erection. He, meanwhile, can't help but stare as she stretches, her breasts threatening to spill out of her top. As they continue, their bodies press against each other, igniting a spark that neither can ignore. They freeze, then slowly turn to face each other, their eyes filled with lust and taboo.
