Stepfather 3 (1992)

After two killer attempts at a happy family, murderer Gene Clifford has escaped the insane asylum and surgically altered his face to look a lot like Robert Wightman so he can marry another hapless single mom and wreak havoc on their lives. Going by the name Keith Grant, he meets Christine Davis (Priscilla Barnes), mom to the wheelchair-bound Andy (David Tom), at a church party and promptly marries her after killing her ex (Stephen Mendel) with a shovel. Andy goes off to live with his dad while his new stepdad tries to knock up his mom, but it turns out she can’t have any more kids. He then turns his attention to another single mom named Jennifer (Season Hubley), but both Keith’s boss and the newly returned Andy pick up on his psycho behavior, therefore becoming his next targets. Priscilla adds another nude role to her already stacked resume with this low-budget horror sequel when one of her nips is briefly seen as she gets into the bathtub, bringing her total to a delicious dozen!
