You’ve been known to get a little kinky. (We know you didn’t get those bruises riding a bike.)

But do you know where to draw the line?

Tomorrow night is the first in a monthly series of erotic life drawing classes at 40 Winks, designer David Carter’s tiny two-room hotel in a restored townhouse near Spitalfields.

Armed with pen and paper, you’ll spend the evening touring the seductive space and doodling tantalizing images of staged scenarios, including an 18th-century aristo awaiting her latest lover, flapper girls in a decadent opium den and other characters posing in provocative Bordello lingerie.

There are prizes at the end for the best and worst pictures, and alcohol is supplied to lower inhibitions and get creativity flowing.

Role playing, visuals and booze — that’s just how you like it.

A little bit sketchy.
