We've seen some weird things on the subway, including flashers, blurry tongue action, and even the Kardashians. But a tipster sent us the above pictures of some serious PDA (warning: the second one is NSFW), and this account of their gross close-encounter:

So I've lived in NYC for fifteen years, never seen anything X-rated on the subway, aside from one or two peeping Toms. Yesterday, around 7 p.m., on Brooklyn bound L train starting from 6th avenue, a guy was going to town feeling up his (presumably) girlfriend, in plain sight of everyone (she had a short skirt or dress, he had it pushed up, hand down her stockings). A kid of about 8/9 was sitting right behind them (eventually his mom got him up and into another section of the car--over his objections; poor woman probably had a lot of questions to answer). People either looked on in shock or moved away; no one said anything. Their activity apparently arrived at a successful conclusion en route to brooklyn, and they exited the train in a daze at Bedford St....Is public sex now acceptable? Is crazy drunken behavior at any time of day now the norm? Random crazy incident?

Well, we knew that the L in the L Train stood for love, but we don't think this level of PDA is anyone's idea of a lovely time.
