some or most people do breath play because of the sense of ownership etc. the one choking gets a sense of superior like everything is in their hands, including the life of the other party while the one getting choked gets off from the feeling of being helpless knowing someone owns them/has control over them. i dont think i explained it really well but anyway breath play is pretty common irl (imo) and i definitely can see where youre coming from when u said u dont know how richard can get off from it but there are really people who likes the thrill/estacy from it
That and also Richard's desire to escape the reality that can be kinda provided by asphyxiation, because years of feeling distaste of being alive can do this to ya
Eh~ it is just me but the recent two updates is not giving it's not like bdsm horny kind of thing lol but more like a self harm thing?? Dunno how can richard got off with that like hmm it just this is just off lol.
