Foreword

After the runaway success of "making love in Japanese", I figured it's about time for the inevitable sequel. Unlike its predecessor, this is intended as more of a hands-on guide, and I hope it will prove usable even without much other knowledge of the language. Slang, obscene and dialect terms have generally been avoided, and any gender-specific terms are flagged with (f) for female speech and (m) for male speech.

That much said, while you may rest assured that your author has selflessly endeavoured to check the content with native speakers in real-life situations, I am not a native speaker myself so use this at your own risk. Corrections and suggestions are welcome.

And a final note: love really is the international language, it is not only possible but preferable to have wild monkey sex without a phrasebook (or E2) in the other hand, and language skills do tend to take a bit of a backseat in the heat of the moment anyway. But a well-placed word or two at the right moment can still do wonders...

でわ、それで発表させていただきます。

His 'n' Hers

This is probably the toughest bit, partly because Japanese women tend to go out of their way to avoid direct references to sex organs, partly because (as in English) many common Japanese terms are either too clinically dry or obscene for use with a lover. I've given a few choices for most, the leftmost ones being the most polite/feminine forms; don't forget that you can very often substitute friendly direction words like kochi and achi.

Words of Action

All verbs given first in dictionary (present tense) form and then conjugated into the -te form, which can be used alone as simple informal command (namete, "lick!"). Add kure to be a bit more polite (namete kure, "please lick (me)") or ageru to say you'll "give" the action to them (namete ageru, "I'll lick you").

undress   nugu 脱ぐ > nuide
tickle    kusuguru 擽る > kusugutte 
touch     sawaru 触る> sawatte
kiss      kisu suru キスする > kisu shite
nibble    kajiru 噛る > kajitte
bite      kamu 噛む > kande
lick      nameru 嘗める > namete
suck      shaburu しゃぶる > shabutte
Not polite; using namete will usually produce the desired result.
insert    ireru 入れる > irete
fuck      hameru 嵌める > hamete
Be careful with this one!
make come ikaseru イカせる > ikasete

Terms of Reaction

First a few more verbs to describe your reactions to the above, this time with the past tense -ta form in case you need to state the obvious...
get hard  tatteru 立ってる > tatteta
get wet   nureru 濡れる > nureta
come      iku イク > itta
Yes, that is the very common Japanese verb "to go". Often written in katakana (as shown) if used in the sexual sense.


...and then some useful things to say.  A few of these have
different forms for male (m) and female (f) speech; any adjective can be
made more masculine by changing -ii into -ee.

Embarrassing.    hazukashii 恥ずかしい
The obligatory female reaction to, um, just about anything the first time around. The expected male reply is daijoubu-da or none at all.
Stop!            yamete 止めて (f), yamero 止めろ (m)
No way!          dame ダメ (m/f), yada やだ (f)

...feels good    kimochi ii 気持いい
...tickles       kusuguttai 擽ったい / kusushii
...hurts         itai 痛い
...feels heavy   omoi 重い / omotai 重たい
More!            motto もっと
Deeper!          fukaku 深く

The observant reader will have noticed that tatsu also means getting an erection, so this is a bit fiddly.

finger-fuck      yubiiri 指入り

...are big.        ookii 大きい, dekai でかい

Further References

Todd and Erika Geers' Making Out in Japanese is a surprisingly good (albeit not perfect) book for miscellaneous dating language, although the section on sex is disappointingly brief. The sequel, creatively entitled More Making Out in Japanese, goes into more detail but is less usable overall. All other "dirty" or "slang" Japanese books I've seen, on the other hand, suck (and E2's Japanese pickup lines node isn't much better).
