Hi, so me, my wife, my sister-in-law and her boyfriend will be spending a week together. My sister-in-law has cheated on her boyfriend several times; however, her boyfriend doesn't seem to have any major flaws and is physically attractive and usually does the right thing. I actually do respect this man, even though I'm generally dominant over him (as I am with most people; I am strongly pathologically prone to hold dominance). Neither women spend much time with him, so he will may be something of a rare treat for both (although me more so for the sister-in-law, but they may try to make the best of their time together). She has described him as a "puppy," but I don't want to completely cut him apart if I don't have to.
There is a four-way female-male attraction between all of us, although my sister-in-law is the most aggressively flirtatious. We have a week, and luckily, I will be the person who drives and this is going to be on my territory. I have the goal of maintaining the most attraction and dominance between the two males.
This is NOT about getting laid/have a swap, this is about maintaining my dominance. That sort of arrangement could go very bad. I generally seduce for social dominance because I'm married (unless if my wife wants something, or if I have a practical reason to seduce, so I'm versed in Indirect Game).
