I'm so glad you like the mixtape!! That means a lot to me haha, asking folks to go listen to a youtube playlist was something of a weird proposal so i'm happy it reached someone.
I think unlike my ideal centaur body more than one pair of tits isn't something that necessarily appeals, at least in part bc of what it would do to my clothing lol. I've seen ppl try and do this with multiple breastforms and the end result often just kind of results in a lumpy tangle up the front of most tshirts. Maybe if it was custom tailored?? I guess i'm thinking "realistically" here though haha.
THAT SAID
The attached picture tho is a GW miniature from when I was younger - the Champion of Slaanesh astride a "steed", one of the loosely defined categories of Slaaneshi beast that's had multiple designs over the years - the ones I remember were like this, decidedly more salacious. I think if I was going to have a setup like that... it'd be something in this vein, with a row of nicely spaced "pseudotorsos" over a serpentine core. As an aside i've always adored the Champion atop this thing too, the horsehair crest is wonderful
