Some classic and new:
Angelina Castro likes it back tight- in this handjob (start at 6:10), she’ll normally keep one hand holding back the skin then jerking the exposed head like a cut cock: [Login to see the link]
These ones are ok, you definitely won’t ever catch a covered head in enter her mouth! [Login to see the link]

Julia Fit works with the foreskin more, but pulls it back TIGHT to suck, great example at 3:35 here: [Login to see the link]
Bj towards the end, she does it too. Also the guy will pull back before entering either of her other holes (especially the one that seems to be the focus of their page)
