Not again, in the morning!

[Kran]

Hi.
Only a couple of childhood movies (thanks VHS, boys of prior generations envy us) are left to identify for my eternal peace of mind.

One of them was dubbed to some Slavic language, but probably a German release.
The scene I remember features some very tired guy in bed. A woman persuades him to have sex with her, and after culmination she begs for more, but he answeres "On no, not again... in the morning!" or something like that (my Slavic is rusty).

The same movie probably has some outdoor scene with curly shorthair blond riding cowgirl on a man on some wooden bench or lounge chair or something like that. She probably has some white thing on or not.
Probably another man comes to talk to the initial guy after that (or not).

That's all I recollect. I scanned through Teeny Excesse and Sandrine Marove movies, but couldn't find it.

Any help appreciated.
