I love BDSM yaoi but sometimes I feel like the people that write it have never actually participated in any kind of BDSM. I really like this story but I have yet to find a BDS Yaoi that really explores a D/S relationship and includes elements like aftercare, sub space, etc. I could rant about this but I will spare you all
