I remember something like that happening in http://www.mangago.me/read-manga/koisuru_boukun/ which you've probably already read, and http://www.mangago.me/read-manga/i_want_to_be_naughty/ one of the sequels has that scene but i don't remember which. >//<
this is the only one i can think of off the top of my head: http://www.mangago.me/read-manga/yatamomo/
definately http://www.mangago.me/read-manga/amaeta_kemono_no_shitsukekata/ seme's got a large sex drive he even continues ramming the uke even when he's fainted
aside from that i am in a tagging rut so you can check my stamina guy tag i'm still adding more. http://www.mangago.me/people/tag/49344/stamina+guy/

This ones pretty good, one of my favourites http://www.mangago.me/read-manga/down_and_dirty/
