Mom Kink

As opposed to a mommy kink, in which someone derives sexual gratification from a woman who babies and dotes over them, with the recipient usually acting in a childlike way, a 'mom kink' is when someone derives sexual gratification from a more mature dynamic, perhaps similar to one between a mom and her teenage son/daughter. This kink is considered more casual, and is characterised by the feeling that it's more similar to a romantic and/or sexual connection between a real mother and son/daughter, as opposed to one between roleplayers who act unrealistically nurturing and childlike.
