Only once have we experienced a situation in which the guy stepped into rough, non-consensual territory. Making sense of this encounter requires context. My wife KK and I were engaged during our college years. There was a period during which KK broke off our engagement. Among other things, she had a "boyfriend," Monty in that interval. Monty's best friend, Steve was his roommate.
Many times during that relationship, Monty tried to set KK up to fuck Steve - he was infatuated with KK, and had watched Monty and KK fuck several times. The closest KK got to Steve, despite Monty's urgings was a pity hand-job. KK told me about it, his little, shriveled, pathetic cock, and how she ultimately ended up laughing hysterically when he tried but failed to cum.
Roll the clock decades ahead - Monty was coming through town on business. KK decided it would be a good thing to hook up with her ex, for old time's sake. I objected - probably the only time ever. I've never liked Monty, for a slew of reasons. I lost the skirmish. KK ended up meeting him for a hotel date. That's where things went way wrong. Turned out Monty was traveling on 'monkey business' with Steve. He tried to force a situation for an MFM threesome with Steve and KK - she had no interest, but he forced the encounter - they essentially raped my wife.
It was the sole situation in my adult life where I took matters into my own hands, got KK to take me to the hotel where Monty and Steve were staying, followed by administering the most brutal ass-kicking I could muster. At first KK was terrified, objecting to the beating, but Steve made the mistake of uttering, "She's just a dirty whore..." things turned and KK started helping, her best shot a right kick to his tiny balls, then a couple of stomps on his crotch for emphasis. Monty got the worst of it. After, he threatened to press charges, but I was able to dissuade him - he's such a dolt his phone was unlocked, which I confiscated during the beating - it contained photos of he and Steve assaulting KK.
