The brother comes home early and interrupts his little sister, apparently he was going to fuck his boyfriend, but he escapes and leaves his little sister tied up and at his mercy, "the truth is that I have been attracted to my sister for a long time ., he barely turned 18 and already has a great body, so I can't let this opportunity pass him by." At first he doesn't want to satisfy her desires, but after cumming inside her several times he begins to awaken her most perverted desires, so I continue filling her with cum until she also reaches climax.
