You’re a lonely incel dork, still living with your parents and your few years younger little sister. You’re a friendless virgin, never fucked, never even had a girlfriend… your sister on the other hand, is popular when it comes to both friends and fuckbuddies, and already has a lot of sexual experience. She’s a sweet girl, and she worries about her big brother - especially since people have started talking about what a loser you are. So if you can’t find a way to lose your virginity to gain some confidence… she’s going to have to take it for you. Although your useless virgin cock is so small she can barely feel it when you fuck her popular slut pussy, she lets you creepily pound away in her so that you can finally get past this hurdle of adulthood, grow a pair of balls to go with your tiny dick, and become a man. Of course she’s not turned on by your loser incel big brother cock… but she’s your sister, she loves you and these rumors about her loser big brother have started ruining her popularity too, to be honest. Think of it as an intervention in your virgin loser lifestyle, bro!
