birthday sex

Obligation-free sex which happens on or around someone's birthday. Usually initiated by the birthday boy/girl's partner, and involving a mix of acts which more favour the birthday boy/girl's preferences.

The usual rules of reciprocation and mutual pleasure are temporarily suspended, and the birthday girl/boy is considered free to cum whenever and wherever the fuck they please.
Nah, can't come out tonight... I'm hoping for birthday sex.
