I Want To Take My Brother-in-laws Virginity

The thoughts have been so bad that I've developed a crush on him... I just want to take his virginity and let my husband be okay with it. I'm not doing it because I want to be with him! I just want to teach him, and be a mentor figure... I want him to like me more maybe too? Or maybe I just want my husband to force him into a chair as I suck his dick and ride him. Show him what good and real pussy feels like.
God, I even get aroused thinking of the brother pulling me aside and grinding into me, or leading me up to his room to show me something, and kissing me for the first time on a whim.
Maybe I'll be shared between them, but only if my husband is okay with it, because if his brother gets too attached he can shut it down, and I feel satisfied with how obsessed this teen is with me.
Might even tease his dick, since I've heard it's small...
Maybe have a threesome where my husband shows him how to please me... God I'm going wild just thinking about it!!
