This is a thing I like to call 'presenting' - where the girl is presenting her mouth or tits to be fucked. Recently fucked mouths and tits also welcome, as long as they're in a similar 'presenting' angle.
This one's a bit of a cheat, but the outline of the guy is easy to ignore.
I remember a particular Dojin where lots of schoolgirls were lined up ready to give their classmates a handsfree blowjob. One panel was exactly a presentation page. Got me diamonds but never could find it again
