If you don't discontinue this relationship, he may sleep with your mother next.

The lady should back out immediately from the relationship or relationgoat.Incest is a very serious crime against God and in African tradition, against Mother Earth.
There are families where incest runs deep in the bloodline; where brothers sleep with sisters, cousins,mothers, sisters do same with fathers and so on.
Incest attracts severe retribution on both offenders and their offspring and it will become a generational curse,afflicting and even killing generations till it is broken.
