Just a few thoughts from a convert to PB.
Girls: vary the amount of makeup, dark lips show the sperm better, eyelash extensions exaggerate blinking due to fear, anxiety etc, dark coloured bra to show cumstaining, or no bra if she has at least 34C breasts and berry-like nipples.
Women/MILFs: There are some very hungry ladies out there, maybe a bit past their prime, who would tart up very nicely with big lingerie rigs, heels, lots of paint. Make them slutty, very slutty, put them in a club setting where their husbands are watching strippers, and then, after an introduction - there is a surprise for these guys as their wives display themselves on stage. They listen to their wives' pre-performance interviews in astonishment, finally watching them perform bukkake...that sort of thing.
I've been to the Ukraine. The young women, and some older ones are always hot and sometimes very beautiful. I've never been disappointed but better to fuck them in Germany - lots of them there. It's much safer in every way. They are perfect for bukkake/gokkun.
Guys: must abstain for at least a week before shooting bukkake. Drink lots of water, and eat pineapples, no meat or fish, or cheese - chicken, duck, turkey, salad, fruit all good. Supplements unnecessary for young males.
Female attendant: should look appealing too, be well presented, especially her hands and fingers which we see a lot of. A wedding ring would add an extra frisson in the light of her occupation. One or two of them look to bite their nails - a real turn-off! They should wear longish fingernail extensions, again in dark colours. These ladies might lick their fingers clean occasionally - sperms won't poison them and it would create a bit more of a bond with the girls they are 'looking after'.
