Barbaric way to impregnate a woman. The correct method would involve firstly restraining a woman. Next a male will proceed to orgasm onto his fist where he will punch the female in the vagina. Repeat with fresh cum every 2-3 hits to insure efficiency on this most delicate of procedures.
This valentine's day my wife and I will be cum knuckling our night away after I take her out for a nice seafood dinner.
I was about to cum knuckle you babe, why do you look so sad?
Cum knuckled is the correct past-tense.
