Is this written by AI or a lawyer ?!
Nothing like that lol, it's just my thoughts on the background and storyline.
After she played with the boss, the first thing she did was fuck Arnold multiple times in her bedroom in front of the husband and she told him not to be involved, just to watch, a very big fuck you to the husband.
This was saying Arnold is who I want to make me cum vaginally.
She did the same after she played with the husband and Mrs Sakura, she woke Arnold up and fucked him, she again didn't want her husband involved by lying on top of him, so Arnold could fuck her deep, plus she showed alot of concern for Arnold when she thought something was wrong.
She also told Erik to wear a condom the next time after she basically encouraged him with the hugs etc and stuck her ass in his face, when she and the husband went to his house.
The husband has been played and Stefany is telling him what's going to happen, it's no longer being agreed by both.
Her preference is Arnold/Erik due to cock size for vaginal sex as they do it for her,
