Is there a yaoi where a seme lets the uke top him once?

http://www.mangago.zone/read-manga/doutei_doudeshou/ they switch in a dj: http://www.mangago.zone/read-manga/doutei_doudeshou_dj_another/

Also
This couple http://www.mangago.zone/read-manga/koi_to_wa_baka_de_aru_koto_da/bt/282016/Vol1_Ch0 here http://www.mangago.zone/read-manga/koi_to_wa_baka_de_aru_koto_da_dj_reversible/

And here, it's not very explicit though http://www.mangago.zone/read-manga/mou_ichido_nando_demo/

It happened at the end of a manga, but I'll spam a bit since it's kinda' a spoiler.

Love Stage

Oh, but the uke topping in ^^^ that one was only about four pages long.

i can't find the last chapter of love stage? where did you read it?

The later few chapters haven't been scanlated becaus eof licensing, but there are raws/summaries up. I'll go dig for it, just gimme a sec~

Looks like I lied. It's only an extra, but still (〜￣Д￣)〜

(I'll stop spamming this thread after this one I promise haha) If you are interested in reading it from the chapters that haven't been updated, it's relatively easy to find raws/summaries just from googling it. I was able to have closure with the series because of this so~
