>>16029186I kind of figured as much; The combination of needing a long penis plus a pair of large breasts really makes it hard to see it as a viable sexual act for the majority of the population.
Furthermore, given that "boob sweat" is a real thing when large breasts are pressed together for awhile, I don't think it would be comfortable for either the penis or the breasts for that kind of thing to happen.
Of course, humans are infinitely kinky people for some strange reason (procreation? i dunno...) and so I'm sure that there is a certain tiny percentage of people who get off on just about anything...
