The Amilia Onyx spa massage video comes to mind. If you don't know what I'm referring you are missing out. Condom snaps while she's riding but it doesn't stop her. It's one of my all time favourite scenes in VR.
I'd love to see a scene that leans into this scenario. Maybe add some plot to make the risk of pregnancy even more taboo.. and then end it with a creampie.
e.g:
-Have her state that she's not on b control & that the condom is absolutely required.
-Have her be step-mom/teacher/hooker/some other taboo relationship with viewer.
There is so many ways to play with this. Could even have some light femdom where she makes a game out of it like "fuck me hard enough and if the condom breaks you earn permission to cum inside". Heck can even have the guy 'lose' by cumming before it breaks, only to go for round 2 and have it break with 2 loads - mama mia! Though I can imagine that 2nd part would be very hard to pull off & shoot.
Hope I'm not the only one who's into this!
