Hahaha! Finally a threesome that doesn't make me want to hit the back button. ;D This is absolutely adorable. I love Harry's blush and really wish that blanket would slip just a bit. And it's so charming that Snape is fully dressed and Harry is apparently gloriously naked. And so shy with those handcuffs and that two-headed dildo. You aren't fooling anyone, hon.
Nice job with the coloring and all the little details. This is just a wonderful piece.
