Line per line romanji Senpai watashi kinō ima tanjōbi dattan desu yo Ikatsu? ? ? ? Yō sukunashi samishi (that mi probably connect to next line but as you can see. .) ? Wasurechi (or cha, depend on what hiragana behind her cheek) sōitsu jibun no ima karade(i?) nde (this hiragana looks like い to me but it doesn't make sense) purezen boku kudasai (in case you haven't got a clue by looking at pic, she meant the present in suggestive way. I understand Japanese can use 'present' in their sentence for this purpose but I can't seem find a way to preserve it, hence I use gift)
Combining all lines together while preserving Japanese grammar oder, I can came up with
Iroha said: Senpai, yesterday was my birthday you know. I get angry you know. (and) I (feel) a bit lonely... Forget about it. Your own body, please give it to me
Last line might seems awkward considering the pic that Iroha is the one stripped. Either that or she asked 8man to gives her (body) a 'present'. 100 minutes for 1 pic. I ever did hardsub and putting hard-translated single doujin page using Paint but now I know translating took one hell of effort. Thanks for 2/3 anon from /jp/ who helped me with 'desu yo~"
