Two sisters, bound by blood and shared curiosity, find themselves alone and horny. They start by masturbating separately, fingers dancing over clits and nipples, their moans echoing in the empty house. Soon, they notice each other through the cracked door, their eyes meeting in a moment of shared lust. Encouraged, they open the doors wide, showing off their wet, pink pussies. They guide each other, instructing on the best spots to touch, the rhythm to use. Their bodies glisten with sweat and squirt, the room filling with their cries of pleasure.
