Hiep and Dam, siblings bound by blood and a shared love for the bottle, find themselves in a familiar scenario - alone, drunk, and horny. Their eyes lock, and the unspoken agreement is made. They stumble to the couch, hands already roaming, lips locked in a sloppy, drunken kiss. Dam's hands are rough, urgent, as he grabs Hiep's ass, pulling her against him. Hiep can feel his hard cock pressing into her stomach, and she grinds against him, her own desire growing. They undress each other, their movements clumsy but eager. Dam's hands are all over Hiep, squeezing her tits, pinching her nipples, rubbing her pussy. Hiep moans, her head thrown back, her hands clawing at Dam's back. Dam lifts her up, positioning her so she can slide down onto his cock. They fuck hard and fast, their bodies slamming together, the sound of their moans and the wet slap of their bodies filling the room. Hiep comes first, her body convulsing, her pussy clamping down on Dam's cock. Dam follows soon after, his cock pulsing as he fills Hiep with his cum. They collapse onto the couch, their bodies slick with sweat and cum, their breaths coming in ragged gasps.
