In the dimly lit prayer room, a hormonal teen brother can't keep his eyes off his sister's curves as she bends over in prayer. His cock tents his pants, aching for release. When she catches him staring, she doesn't scold him, but instead, leads him to the closet for some 'private' time. She strips off her modest dress, revealing her ripe, untouched body. He hesitates, but she guides his hand to her wet, virgin pussy. As he fingers her, she gasps, "You won't tell anyone, right?" Their secret sin escalates as they lose themselves in each other's arms, their bodies moving in sync, their moans muffled by the clothes they're still wearing.
