The pic that is currently my avatar is probably my all time favorite pic. It was one of the first pics I saw when I discovered incest mom-son toon porn. Everything about this pic is just amazing, I could look at this all day... the hot Mom with a perfect body wearing that tiny slingshot bikini in front of this so obviously aroused boy... his arm around her waist and ass and the bulge in his speedo's, I love how it looks like he knows he doesn't have a reason to be ashamed or embarassed for getting a hardon in front of this gorgeous woman- she knows it too, she dresses like that for him, she enjoys the effect she has on him, and she is willing to take responsibility for his arousal and help him, guide him to become a man with her.
The entire comic that follows this milf seduce her son's best friend and later has sex with both of them all on their summer vacation is pretty hot, but this pic is by far the sexiest scene for me.
