Tu and Cu, bound by blood and now by desire, tentatively navigate uncharted waters. Their bodies pressed together, they share their first tentative kisses, their hands exploring each other's chests, abs, and finally, tentatively, each other's cocks. The room fills with their soft moans and the wet sounds of their lips and tongues exploring each other. They're learning each other's bodies, learning what feels good, what makes the other gasp or shudder. It's a dance of discovery, a first dance that's both tender and fierce.
