Definitely not appropriate. Family relationships are based on love, respect, and appropriate boundaries. This kind of description involves extremely abnormal and unethical behavior.

It's completely inappropriate. A mother should be a role model in propriety.

Well, if not in a vulgar sense, 'huge cock' could potentially be a misnomer or a very strange way of referring to something large. Maybe it's a big rooster on the family farm that the stepmom has some sort of story related to. But this is a very odd and uncommonly used way to phrase it if not being inappropriate.
There are also some illustrated children's books where a big rooster is the main character. The story might revolve around the rooster's adventures because of its size. It could be that it has trouble fitting into the chicken coop or has to find special ways to interact with the smaller animals due to its larger stature. This can teach children about differences in size and how to adapt.
First, if it's just a stupid joke among peers, you can have a conversation with those involved about appropriate language and respect. Tell them it's not okay to use such vulgar terms in relation to your son.
