Okay, i am dying to know what this says.

I decided to try myself but finding the Kanji was more trouble than it was worth. Still...

Google got me this:

Uhh ... is
Patience with each ...
Because one had to ...

Shitsuko Us
It is too strong momentum
To protrude
There I was away

Babylon gets this:

I can't put up with the rain ... with one ... have ... Please call momentum I too have been forced out

Original text:

はうう。。。
ずっと我慢
じてたからつ

おしっこ
勢い強すぎて
はみだして
しまいましたぁ

Word by word translation:

*Moan/Groan effect*
Long(duration) Patience
'To do' (Because of)

Pee
Forceful (adj/adv) Strong (i -> sugite, "too", adj)
'To Force Out' (verb, te form connection)
'To finish' (With a 'regretful' / 'finally' connotation)

My preferred translation:

Hau....
Because I waited so long...

I went with too much force...

Dunno if someone will come around and fix it to be more true to the original, but I gave it a shot and got in some practice while I was at it.

...

I don't even know why I translated that >_>

When I thought my tag blacklist was strong enough, there are things that I hadn't considered.

In a place like this, there always will be.
