MD/lb 

Mommy Dom/little boy. Related to MD/lg, DD/lg, and DD/lb. Ageplay, usually sexual, between a female dom and a male sub, where the dom plays the motherly figure and the sub plays a little boy.

MommyDom: My son was being... naughty today. ;) I had to give him a little spanking! Maybe a small MD/lb reward for not crying?
Me: hwat the fuck

Headspace MD/LB 

Headspace is where a partner in the group has a sort of alter ego where they enjoy slipping into the headspace of a younger child as a stress reliever. Most people in there little space( head space) call there caregiver( other partner) mommy or daddy. A mommy in a partnership is where the other partner has a mommy kink and is enjoyed being called mommy or mistress or miss and has the job of acting like a mommy when they’re in headspace but sometimes they have a mommy kink which makes the whole relationship kinkier. Perhaps the little of the partnership breaks a vase or is throwing a tantrum or says no or even brakes rules. Then the mommy in the group will punish them. Here’s an example (don’t forget the little always has consent and safe word and they can enjoy it)

Mommy: baby boy come here for a minute
Little: yes mommy ( in headspace MD/LB
Mommy: did you break one of my rules and eat those cookies with out permission.
Little: (starts to cry) I’m sorry mommy I need a punishment.
Mommy: come lay on my lap baby boy I’m going to spank you 25 times you will thank me after each one

Then you can picture the rest

mdlb 

MDlb is a form of BDSM play or it can just be a type of role play. MD stands for Mommy Dom. lb stands for Little Boy. Mommy Dom Little Boy. The same way there is Daddy Dom Little Girl (DDLG) It's when a female acts as a Mother and her significant other acts as the little boy. This has nothing to do with actually wanting to date or have sexual relations with your son or mother. The mother role will feel empowered and protective over her "little boy" and the boy will feel like he can be released of any responsibility but giving up control is also very freeing. The mother role might also make rules that the "little boy" has to follow or it can resort to punishments depending on the agreement between the couple.

Any BDSM relationship should be safe and consensual.

Guy: I want you to act like a mother figure.

Girl: You want to do mdlb?
