I find my sister, Kiarra, incredibly attractive. I enjoy observing her while she practices yoga and stretches; however, today she detected me peeping at her. I admit to Kiarra that I struggle to concentrate knowing she's in her bedroom stretching and flexing in her leggings. I move closer and begin caressing her round rear. Overwhelmed by desire, I tear her pants while she's on all fours. I notice her vagina is moist, indicating she desires me to penetrate her with my substantial manhood. I vigorously thrust into my sister's vagina until I ejaculate inside her.
