Keepureyeson's Taboo Closet Temptation

In a cramped, stuffy closet, two siblings, bound by blood and religious upbringing, find their bodies betraying them. The brother, a towering figure of barely-contained lust, leans in, his breath hot on his sister's neck. She shivers, her nipples hardening against her lacy bra as he grinds his erection against her ass. She whimpers, her fingers twitching with the urge to touch him, to feel the length of him in her hands. Their eyes meet in the darkness, and the unsaid passes between them - they're going to hell for this, but they don't care.
