Your nerdy little sister comes to you and confesses that she's grown curious about sex. Especially since most of her friends have started having it, and they all complained that their first time really hurt. Shes hoping that since you've always been a caring and protective brother that you would take her virginity. You seem hesitant at first but she starts to beg and plead as she shows you her holes. She hears you unzip your pants and clumsily sucks on your cock until you tell her to lay down. She trusts you and promises to be quiet bc mom and dad are in the next room. You kiss her gently and slowly slide into her, she whimpers and moans thankful pleas for more. As she falls in love with the feeling of your cock she starts to fantasize what would happen of she were to get pregnant by your load of cum. She loves this idea and you start to pound her harder and harder , she seems a little hesitant of whether or not shes enjoying this but she knows that its supposed to hurt the first time. She begs for you to cum her and wants to do this all of the time now. She doesn't care how wrong it is to fuck your sister, she just needs your cock
