OK, bad choice of words, yours does seem to apply better. I'm reluctant to use the word prostitution, you have to admit it does have a kind of stigma attached to it, and I'm not sure if it applies, since all the activities are between us both. It seems to be a bit of a grey area to me.
I don't have the list to hand right now, so I'll probably forget something, but as I recall it has handjob, blowjob, vaginal and anal sex, varying degrees of spanking, and bonuses for her if an outfit or roleplay is involved, or if she takes my come in her mouth. I think we've covered all the 'sexual' basics, but I needed some ideas for punishments, as all I have is spanking.
