I don't know. I guess it was the standard theatrical release. And the director was present afterwards for a QaA and there was no hint at different versions.
The scene starts with her sitting on a bed and the guy standing before her. She pulls her top off and we see her tits from the side. Then she reaches for his trousers and loosens his belt but it's shot in a way that the action is right outside the frame. Then there is a cut and both are nude. Janaina is lying on the bed and the camera is looking between her legs. This is where you see her pubes for a second. It's partly obscured by the guy and only briefly visible but it is clear, that her labia aren't shaved. Maybe if you could stop the frame you could probably see her labia under her pubes as they weren't very dense but without the ability to stop the frame I can't be sure. It was just too brief. The rest of the sex scene is quite standard. The guy is humping her missionary and sucks her tits once. There is a brief zoom on the groins while humping. This is where I think I made out the outline of the guy's balls for a split second. But as before without a freeze frame no way to be sure. All in all I think the sex was simulated. No oral in this scene. The duration was around 1 min I guess.
No. She only licks her friend. There is some serious hand movement suggesting real fingering, but it isn't shown explicitely. Janaina has no sex scenes with other men.
As for the masturbation scene: Janaina is lying on her bed. You get a good view of her tits and there is definitly rubbing going on between her legs.
As I mentioned afterwards she is licking her fingers, but there is a cut so it is very unlikely, that she is actually licking her real wetness from her masturbation from her fingers. During this cut the camera also changes. The masturbation is shot as it would be seen through a webcam with lower resolution than the rest of the film and a static camera position suggesting she is streaming it like she is also doing in some other scenes (and the trailer). The finger licking is then shot with the normal film camera again. Hence my doubts about this.
