Things get hot and heavy in the summer issue of V Magazine, which features a raunchy, bondage-themed spread starring Katy Perry and Madonna. Although Perry has admitted to having kissed a girl (and apparently liking it a lot), she's never done anything this risqué before.

The spread sees Perry as the dominatrix, tying up and straddling the Queen of Pop. The two stripped down to tight, cleavage-baring corsets and thigh-high boots for photographer Steven Klein, who's shot this kind of thing in the past before (remember his video for Lady Gaga's "Alejandro"?). Although this is the first time Perry and Madonna have appeared together, it certainly wasn't the first time Madge has teamed up with Klein, who's shot a number of her projects before.

Apparently the racy shoot also took a toll on both pop stars' bodies.

"I was sore in my upper body and in my butt area from all that squatting," Perry told V Magazine. Madonna also added: "It's good to be sore in your butt. My neck is sore from that wonderful moment when I was sucking on your heel."
