Neighbors have started noticing strange occurrences as my younger brother and his girlfriend have been having sex at home every single day. Their moans are incredibly loud—each time she climaxes, she screams out "An-an, I'm cumming, cumming!" so loudly it can be heard from outside the house. Even though they're living with our parents, they're carrying on like this, drawing disgusted looks from everyone around. On top of that, his girlfriend is arrogant and shameless, routinely walking around the house in nothing but a single bath towel or her underwear after showers. Every time, she insults me: "Ugh, gross, what are you staring at?" or "You were listening to us earlier, weren't you? Seriously, you're so creepy." Because she's exceptionally good-looking, people's judgment toward her behavior is even harsher. After enduring this situation day after day, I've finally reached my limit and decided to take disciplinary action. As my brother once again acts with his usual arrogance, I grab him by the neck and head, forcefully shoving my cock into his girlfriend's smug mouth. I brutally dominate her mouth, deepthroating her without mercy, then unload thick, white cum all over her pretty face. Naturally, one facial isn't enough. I pin her down as she struggles, then ram my older brother's cock into her pussy, repeatedly filling her tight vagina with sperm over and over again. Gradually, she begins to appear more submissive. But now... the real fun is just beginning...
