You walk into your sisters room totally naked. You want a reaction. This is the best way, you believe, that you'll get an honest response from a girl about your dick size. And she gives it to you. She's really not that upset about it. But... her words are confusing you. She's telling you that your dick is "just fine"... "it wouldn't hurt"... "would mostly tickle"... She doesn't mind that it's "not very big". And she thinks most girls wouldn't mind it at all! Well, that kind of messed with your ego! However, what she suggests is that you really practice eating pussy. While your dick could pleasure someone to a point, she thinks you'll have to finish a girl off with some serious pussy eating skill. You admit that you've never done it... and wonder... will she let you eat her out? Of course! She's a good sister, isn't she?
