I love cum ⇐ Incest

[Guest]

This topic is only indirectly related to incest.
After all, this fetish is possible even in a non-incest relationship.
It is possible alone.
Oh yes, the point is that after ejaculation, lick from a partner or partners their own seed.
Whoever read Janusz Wisniewski, in his most famous novel “Loneliness on the Net,” there was a whole chapter where they talked about this.
In general, who loves sperm? Yours/someone else's?
