My brother, who had not been home in a while, returned to his childhood home. His sister greeted him, and they reminisced about old times and talked about love over drinks in the living room. As they drank more, they started talking about adult topics. Eventually, his sister got drunk and fell asleep. The brother was concerned for her but became aroused by her sleeping figure. He sat next to her, smelling her scent, and began to masturbate. Soon, his sister woke up and saw him gripping his penis beside her, causing her to be shocked. The brother desperately apologized. Seeing her brother like this, the sister decided to help him with his masturbation so that their family wouldn't find out. The brother demanded various things such as licking her breasts, showing her vagina, and letting him lick her vagina. The kind sister agreed to all of his demands. As she gradually began to feel pleasure and almost let out a moan, the sister suppressed her voice so that their family wouldn't hear. The brother said he wanted to ejaculate through dry humping, so they started. The brother accidentally penetrated her. Unable to make a sound, the sister was made to receive his semen inside her.
