Your brother told you about what he and mommy get up to in secret and you come to ask mommy if you can do the same. Mommy explains that what her and your brother do together is special to them. You’re far too small to give mommy that kind of satisfaction. You pull your tiny cock out to show her but it only proves mommy’s point. Unlike your brother, you just never really grew and that shrimp dick of yours just won’t do. Aren’t you embarrassed to even get that out in front of mommy? She gets a dildo out to show you what your brother’s cock is like and sizes you up against it. You see how good it looks between mommy’s tits? In her mouth? Yours could never do this. But mommy feels bad for being so honest with you, so as a consolation she strokes your little cock and asks you to cum for her. Hurry up though, she’s going to go and meet your brother soon. Don’t make mommy late.
