Yaoi Rule #1: The uke always gets undressed first. ლ(´ڡ`ლ)

Hey guys. Looking for a manga. I don't remember much, but someone earlier posted about it. The uke is very violent and often hits the seme, who doesn't mind. There's a story 'bout this couple (and I remember it being a comic relief strip) where they're discussing the animals they like, which are cat and dog. Someone (I think a friend) says people who prefer dogs are usually sadist and people who prefer cats are masochists, naturally comparing them with the couple.

Please, I BEG, help US find this manga. After the user's post, me and three friends engaged on a day-long search with no results. We are a little frustrated as we all read this manga u_u

Thanks in advance!
