Shouts, giggles and selfies. Mildly titillating and lots of fun, bouncing around on giant inflatable boobs is the hit attraction of a hot and steamy New York summer.
As temperatures rise and hemlines shorten, visitors flock to the Museum of Sex to jump up and down on an adult "moonbounce" (or bouncy castle) called Jump for Joy and nicknamed "House of Boobs".
It is the set piece in a flirty exhibition mounted by London-based conceptual art duo Bompas and Parr, and inspired by the naughtiness of an old-fashioned British or French funfair.
Shrieks of "Oh my God I'm not going on that!" or "I'm definitely going on that!" ring out from the low-lit corner where the boob castle stands erect, shoes quickly kicked off for a frolic.
Oversized breasts protrude from its walls in every shape and colour as couples and groups of girls fling themselves around, laughing in delight and snapping pictures on phones and cameras.
"The boob jump house was fun," New Jersey teacher Michelle Allen says when asked about the best bit. "It's like adult fun."
