Well in Victorian times which would be the classical prossying era in some eyes, your standard tuppeny knee-trembler would consist of wedging your bellend between the lady's clamped together thighs whilst stood up against a wall round the back of a seedy pub.
You would grunt to a disappointing spurtage while clamping a ciggy in your gob rather than kiss her face. Both male and female participants in this act of shocking depravity would probably smell and be soiled too.
If they were really adventurous you could do it doggy providing they turned round, but it would still be thighs not actual minge.
