A full on, skillful blow job starting from flaccid & continuing all the way up to & including ejaculation without breaking contact between penis & mouth or even temporarily substituting a hand or sex toy.
My boyfriend has been particularly awesome lately, really considerate, thoughtful & loving; so I started tonight's bedroom gymnastics with a spunk-a-dunk.
Meaning totally exhausted. Derived from a combination of knackered & f*cked. (Probably during a bout of severe inebriation!)
Had a mint day/night out, but now I'm kerflucked & ready for my bed!
