When my sister came to wake me up and pulled back the covers, my dick was exposed as a morning wood! Unable to resist the long-awaited erection, my horny sister quietly straddled me and rubbed her raw pussy against me to relieve my sexual desire! However, as soon as I woke up, she slipped in and came inside me! My sister was no longer able to control herself and came repeatedly in a slow piston-like cowgirl position, as if savoring the pleasure she hadn't felt in a long time! My sister lost her senses when she accidentally saw my dick and changed radically!
