Virtually everything by Zaria is ***extremely*** hot.

One Hundred Percent agree with the sex scene choice
i contemplated this question for a while, and I still can't really come up with a response
this is the real question for fujioshi; so I just compiled several of memorable sex scenes
(in no particular order at all)
1) Namida Hanamizu Gusyogusyo Danshi
(Nekota's sex scenes are top notch and this "series" is just pretty much a giant sex scene; this is the particular short chapter/extra I liked a lot)

2) Watanabe Asia's works (specifically Mitsubana and Pink no Omocha)
(Watanabe Asia's works are also pretty great [however semi shots warning] )

3) some more that I'm too lazy to label
