if you want more 3P check out my list
this was it thanks
thanks for the link
no probs :) enjoy!
can someone remember a similar 3p manga but in that story the 3 main characters were friends and both seme liked the uke from the start. I think they were creating a bl game instead of adult toys. Can't help seeing the resemblance with this one.
