In this adult sister role-play, I stay at my girlfriend’s home for the first time and become fixated on her shy sister Emika as she naps with her slender thighs exposed beneath her skirt. She flinches when I touch her delicate body, whispers for me to stop, and weakly tries to push me away, only fueling my desire until I pin her shoulders down. Soon she trembles, clings to my arm, and lets out soft moans. Her awkward reactions become irresistible, and I repeatedly take her slender body until there is no turning back.
