I've been trying to come up with a good tag name for what's going on in these images, which is basically a variant of frottage where one of the character has a pair of hemipenes and the other slips his own penis between the two :
It seems to me like this is unique enough to deserve its own tag, yet I'm not entirely sure how to unambiguously tag this. I'm tempted to go with bifurcation_frottage, or something along those lines, but bifurcated_penis currently refers to the result of genital_bisection so, while this would still technically hold true in both cases (hemipenes being more or less a case of natural bifurcation), I wonder if there may not be another way to tag this that might be easier on people's blacklists.
I've also seen the oral variant pop up a few times, and while I'd ideally try and make both sound related, even bifurcation_licking doesn't sound quite right...
Any suggestions?
