right not it does not seem like any of the "BBC family" would mind if any of the girls (their own stepmom included) to have fun with eric. by your logic, EVERYONE in this game is a cuckwell, he was humiliating Sai, but then it will be Eric's turn, remember that there are the BBC, and the comparison is all pro BBC, so, the next humiliated ERIC.
or maybe they are all rly free-spirited and want to have fun together w/o big drama ore jelousy
