#55 and #56 on this list have cell phones anally inserted. If it's not one of these, then I'm following this in case someone gives you a link (so I can add it to this collection) :P

Or rather here, if this is it... http://www.mangago.zone/read-manga/tengen_toppa_gurren_lagann_dj_zwinger/
It was a doujinshi and remember cellphone in butt.
There was also something else. So there was a character a who liked character b and gave him a cellphone. Character c and character b were playin sweaty sweaty milk milk but suddenly character a calls character b. So character c, jealous, answers and hangs up. However, character c is a wanted criminal character a and character b were trying to catch. Character a, recognizing this voice, calls character b again. Then, character c still sees that number and decides to put it in character b's anus.
Now, the real question is why can I remember a yaoi manga from a couple months ago but still cant remember the mitochondria is the powerhouse of the cell? QAQ
(also character c's name may or may not be simon. My memory is a bit iffy)
