Maybe, but then all but one of the other pics currently tagged cheating would have to be re-tagged, as they're in the context of marital infidelity. Either this image and this one would get a new tag, or they'll get the "cheating" tag while the other 400+ images currently tagged "cheating" would have to get re-tagged (to "cuckold" or "cuckoldry," perhaps?), and neither is a task I'm keen to undertake.
A quick look at the wiki pages reveals that a "cheating_(competitive)" tag exists. I retagged the image you linked accordingly, and I'll go ahead and put the tag here as well, even if it's not strictly "competitive".
(the cheating_(competitive) tag is very underpopulated, so it may have been just created by one of you two, but it's there and that's what matters)
Up! Very well... And this one?I'd like to do a vision test. Can you tell me which way this C is facing?
