It is not exactly a cleanup or creampie fantasy but it is related, and definitely a cuckold fantasy : have you ever seen a movie where the wife (/girl) takes a cumshot from her lover (/any man around) and before even swallowing, go on and suck her cuckold husband (/other man) around, with her mouth still full of cum ? I imagine the sensation should be terrific for both the slutty wife and the cuckold husband !

In my opinion I would find such a scene very exciting and would be grateful if anyone could post this kind of stuff, or even tell us about his/her experience about it ?
Thank you all for your contribution.
