Two siblings, bound by blood and desire, steal moments of ecstasy in the dimly lit confines of their shared space. The first time is tentative, fingers brushing against throbbing members, gasps stifled against pillows. The second time, they're more bold, the girl's hand wrapping around her brother's thickness, guiding it towards her warmth. Their bodies move in sync, sweat-slicked skin sliding against each other, breaths coming in ragged gasps. They're careful, always listening for footsteps, always ready to pull away. But the thrill of the forbidden only heightens their pleasure.
