Dimitrescu Daughters x Reader smut

I haven't seen anything regarding the three sisters x reader, so I obviously had to take this into my own hands. Forgive me for any confusing parts; I am asexual as hell and have no experience in this. The lady is only mentioned in passing, so do not expect her to be a prominent part of this. There are plenty of other fics for that. Also, this does not make much sense plot-wise, and y/n is a bit dull, but no one is here for the plot. I also tried to make y/n as gender neutral as possible, so it should be a comfortable self insert hopefully.
