Instead of just posting a link to my Provocative Shop (Warning: maybe it's not the best idea to visit this site in the office, this is harmless, but seems to be dangerous, and it's not easy to convince your boss, it's rather art and fun, not something adult), I explain you two T-shirt designs of mine.

This is a BDSM-related one. To avoid censorship, I didn't depict any human models, you can find only some really symbolic and abstracted objects (cuffs chained to a collar, a ball gag, a flogger, a crop and some lingerie). The title of this colorful and decorative composition is Heaven, a kinky heaven with submissive angels.

This is a strongly abstracted depiction of a really hard topic: bukkake. It's a really rude action, a couple of men form a circle with a woman in the middle... That should be enough for you, although you can find an article about it on wikipedia without any age restriction, I don't suggest to visit it, if you are under 18. I changed all the persons to the common symbols of the two genders, I added a colorful background, and that's all. This is a really hidden provocation, and there are many other interpretations, too.
