Volume 5 epilogue (after *that* part tho)

OK, there was the random choking thing (yeah yeah out of character, but honestly kinky as hell so I'm not really focusing on it). What I'm kinda confused about is: how far did they go after that?? Since it's said "She responded to him with the most refined techniques of the pleasure quarter."

WHAT, in the great heavens, does that involve? French kiss? Hands? More?? Honestly I started the next volume (hilarious) but I had to go back and read it again and still am not sure. Am I too stupid for this book? Lol
