KK's favorite encounters by far are multi-male, from MFM to FM+. We've done it all, from threesomes to orgies.
KK and I categorize a gangbang as three or more men, with her as the center. Three men and KK we label as a "mini-gangbang." Her favorite configuration is 5 - 6 men. That grouping means at least one guy is always hard, and there's a good chance she can continuously enjoy a hard cock in her mouth, pussy, and ass, while some of the guys are going through their refractory phase.
We lump together two styles of gangbang; the "dog-pile," in which KK is being serviced by multiple men simultaneously, and "pulling a train," the scenario in which KK takes one man after another, sequentially. She prefers the "dog-pile." KK's first gangbang experiences were during our undergrad years. Her first true gangbang was at a bachelor party. At the time, KK was doing gig work as a lingerie model. Two guys hired her during a lunch-time show to appear later that evening at their friend's bachelor party - they paid her extra, the expectation that in addition to modeling and dancing, she'd blow the groom after they tied him to a chair. Things progressed from that to KK pulling a train, fucking and blowing all the attendees. Her next event was pulling a train at a frat party. That in turn led to KK becoming the frat house "fuck toy." I never knew about this until much later in life.
We've done orgies, but fewer in number. KK's preference is that I'm not engaging in sex with other women, which is hard to avoid in a no-holds-barred traditional orgy.
