For the paizuri fans, here are three hour-long tittyfucking compilations with the lovely Ai Sayama, one of the real stars in the paizuri genre.

My only complaint is a lack of straddling guy-on-top-girl-on-her-back scenes, but in the last compilation we have a really good one, starting at approximately 21 minutes, where she teases the guy by letting go of her breasts, then tickling/fondling the tip of his erection before putting her arms above her head and encouraging him to use his own hands to push her breasts together for a finish.
For one of my fav straddling scenes (non-paizuri) I refer to this one, which ends with two guys, one after the other, cumming between ebony Destany's lovely breasts:

Because I'm a huge white-guy-black-girl fan my absolute favourite titfuck scene remains the one (starting at 20 minutes) in this 1980s Heather Hunter movie, with an unusually long session (almost 2½ minutes) of Heather's awesome chest being plowed. That she is getting her pussy eaten at the same time is another bonus (I'm a huge white-guy-eating-black-girl-out fan as well), as her pleasure at this double attention is obviously real (not that Heather ever seemed to fake her pleasure in her scenes).
