I thought part of being a wet nurse was to stay lactating or to give away her milk oversupply. I understand lactating breasts can feel uncomfortable which is part of the reason for using a breast pump to express milk to be used later. Also nipple pads to soak up the milk dribbles rather than it going through your bra and then there being a tell tale embarrassing wet patch on your blouse/t-shirt.
However, in regard to erotic lactation. Yes, it exists. Some people really go for it. As well as dressing up as an adult baby and sleeping in an adult sized cot. Yes, really.
Think of the comedy show sketch where a grown adult male starts asking for the breast as in, 'bitty'........want bitty now. At which point the stupid mother gets her breast out and the man suckles away at her nipple at a family meal at a restaurant. Well, imagine that done in private as a sexual kick. You get the picture.
There was a thread a couple of days ago where a poster had discovered her husband sex dolls and was shocked. Another poster linked the top ten weird internet sites, one of which was a site for adults who like to wear adult incontinence pants and get a sexual kick out of messing themselves and being changed.
It wasn't far from that site to erotic lactation. Honestly, the things I've learned on MN !
