Vanessa has magnificent natural breasts. They are humungous and she doesn't mind showing them to you and letting you feel them.
So of course when she changes your wet diaper you have a big stiffy, even more so when she wipes it slowly and thoroughly clean with wet wipes.
She wants to make you cum too! Can you do that for her? Will you cum if she lowers her mouth over your rigid willy and sucks you off?
She would be so happy with you if you could do that! Just help things along she lets you finger her pussy through her panties.
