The Argentine sun bears down on the twins as they lounge by the pool, their skin glistening with sweat and sunscreen. They giggle nervously, their eyes flicking to the hidden camera. One twin reaches out, tracing a finger along the other's thigh, her touch light as a feather. The recipient's breath catches, her eyes fluttering closed. The touch becomes bolder, more insistent, as they lose themselves in the heat of the moment and the unspoken promise of what's to come.
