Your mom walks in on you sniffing and putting your sisters panties in your mouth. Concerned, she sits you down on your sisters bed and asks if you have a thing for your sister. You admit that thinking about your sister and touching her panties gets you excited. Your mom explains that it’d be a really bad thing if other people found out about this, especially your sister. She says that we can’t have these feelings for your sister turn into something worse so we have to get it out of your system. Mommy has an idea though, not to worry. She gets on her knees and pulls out a pair of your sisters panties. She asks you if it’s making you excited and then points out your cock growing harder in your pants. Mommy asks you to take it out and starts rubbing the panties over the tip of your cock. She wraps it around the base and starts to suck and gag on your cock. You love your family so much don’t you? You’re such a good boy for mommy. Cum for mommy and your sister.
