Bar hopping a few years ago overseas, mate got a bbbj under the table from a lady who then deposited his cum in her friends pussy.
When she offered same service to me I declined. During the evening I saw then do this a few more times but also swapping.
Turns out they were a lesbian pair trying to get pregnant and didn't want a dick inserted.
The sperms are mostly gonna have died with the saliva in the mouth and the fact that they then still need to travel through to the uterus.
No way that's gonna work. Or very unlikely to conceive like that.
I'd say yes. While I do enjoy scouting for new pitchers, I do enjoy my starting rotations. Nice when you don't have to start from zero. Sure, it's BUSINESS, but they do care if you're enjoying. There's been times when my eyes were bigger than my stomach (or some body part), after pounding away, couldn't get over the top, just too tired to finish. I'd say not her fault, just too tired, no problem. While a scouting prospect would be fine with quitting, regulars would not accept defeat, and work to reinvigorate me to finish the job. Their work ethic is appreciated.
As to strange request, not so strange, but a number would request I get out my egg/torpedo vibrator for THEIR enjoyment (different clime where LT was the norm).
