You come home and your little sister is sat on the couch looking fed up. You ask her what's wrong and she shyly confesses that the other girls at school have been teasing her for still being a virgin. She says none of the boys will pay her any attention because they all think she's a shy good girl. She confesses that she's desperate to find out what it feels like and even admits that she's been secretly stealing one of mum's toys to use for practise. She tells you how hard she's been cumming using mum's dildo and you can't help the swelling in your pants. She notices your boner with surprise and delight, she's never given anyone a boner before! She begs you to let her see as she's never seen one before and yours is right there in front of her. She asks if you'll let her put it in her mouth just for a minute so she can know what it feels like and you can't resist. She loves sucking your cock so much that she begs for you to put it in her pussy just for a minute, she's so desperate to know how it feels and your cock is already so hard. You fuck her slowly at first, but she loves it when you start to speed up and give her a good pounding. You bend her over and she cums all over your cock in doggy before begging you to cum inside her virgin pussy. You pound her hard and leave a huge load of cum deep inside her tight little virgin pussy! You're such a good brother ;)
