Looking at the cleavage and thighs of his sleeping, drunk older sister, a younger brother who had recently broken up with his girlfriend began to masturbate. Noticing this, the older sister said, "Shall I help you?" and showed him her panties and breasts, and responded to his advances with manual stimulation and fellatio. Eventually, they began bare skin contact, but unexpectedly slipped in! Even with the cry of "It's inside!", the younger brother's hips didn't stop, and the older sister began to feel it too...
