Little
Little refers to a submissive person,
usually a woman, who role plays a younger age.
The little is the
little girl or little boy in a daddy-dom BDSM role playing act.
This
person is dominated by a daddy. In rarer instances,
the dominant
person may be a mommy. Some little dresses for the part and / or
they also
alter their voice to seem younger.
It is said that the daddy-dom and
little girl dynamic
presents a more relatable side of BDSM.
The act
is more about taking care of each partner's needs.
The daddy gets to
impose his masculinity positively onto his partner.
The little, on the other hand, receives the attention
and care that they crave.
There might be some spanking involved if
the little has been behaving badly.
