The scene has four things that I'm so fond of: group sex, slimy tongues performing spitplay, sodomy and abuse. Those are the pros, and just fot that it deserves a good review: it's hot, kinky sex in a free scene, so good job BANANANA! The cons are that when I tried to tweak it in order to make a gay scene with it, using my own male (and AltFuta) characters, I discovered, to my surprise, that the person performing penetration is always the same, and that they only swap hair presets (not my cup of tea those hair presets) from one stage to another, and I cannot find out what triggers that hair preset swapping. Good material, anyways!
This scene was originally created by reusing a one-on-one sex scene.
Basically, it's just "_1Woman" and "_2Man" having sex, and the other guys are just animated a little with Cycle Force and crimeless's "RandomCycleAnimator".
The three guys have swapped their clothes and hairstyles to make it look like they're taking turns having sex with the girl.
Either "BTN_40_Man-Pt1" or 2 or 3 is pressed as a trigger, which causes the character's clothing to change.
If you want to change the character, it would be easier to
1) delete the button above
2) change the character's appearance using "Appearance Presets" up until 0.4 seconds (fade-in) of "Sex1" on the timeline.
