Bonobo apes are known to engage in fellatio from time to time, so what I want to know is, do they swallow? Google searches on the topic haven’t answered my question, only informed me that some porn sites do indeed use “bonobo” as a keyword.
My WAG is that, like humans, some bonobos swallow, and some don’t.
Now that I think of it, I’m not even sure they do it to orgasm. I would assume so, since it takes them about 13 seconds on average to climax, from what I’ve read.
Reminds me of the joke about Michael Jackson being caught blowing Bubbles.
