There are so many threads with slight variation of the same idea... randomly chose this one to post.
Usually not my cup of tea, I never watch any sperm-cific or gokkun vid. But I do like it (love it!) when there's a great BJ or sperm scene in a "regular" JAV. E.g.
ABP-473 All Naked Cosplay Shunka Ayami (click for full res)
Only 5 (?) loads of cum, so maybe not good enough for you sperm-addicts, but (1) Shunka is an S-class idol, (2) the title is not sperm-centric but other-themed (zenra and cosplay) so its a bonus to a great multi-facial. And honestly, the cum shots are so well placed, drapping just so on her hair, eyes, nose, cheek, tongue, chin, it's literally a work of art. So ... I LOVE IT!
BTW, this scene made me wonder ... Shunka was doing a great job sucking all those cocks, but when it comes to making facial, each cock was taken out of her mouth and hands and each guy jerked his own penis to make the money shot. Have you seen any great facial shot in which the girl was doing the hand job and aiming the cumshot on her own face? Usually either the guy delivers the facial or if the girl is doing the jerking off, she shots the cum either taken into her mouth or on her chest, not on her face.
