Sins of the flesh in the name of virtue

In a small, stuffy closet, two siblings, driven by an unspoken desire, succumb to their forbidden urges. Clothed in only their underwear, they press against each other, their bodies burning with a secret passion. The brother's massive cock tents his boxers, while the sister's nipples harden against her thin shirt. They struggle to maintain control, but the heat between them is too intense. They begin to touch, hesitantly at first, then with growing urgency, their hands exploring each other's bodies, their breaths coming in ragged gasps.
