A new and exciting urban delecacy - obviously only for those clubs with "adult" tastes. When ordered, a man with a gimp suit and assless chaps shows up at your table with a shot of espresso and a long straw. You masturbate (or fuck) and cum into his ass, then use the straw to suck it out (aka "felching") and spit it into your espresso. Drink it up baby - it's delicious!
After a long night of dancing, I was happy to see that the all night cafe offered the Belgian Felchin' Cappuccino - I needed a good fuck and some caffeine to get me through until morning.
