Confront them

Deciding that trying to hide is beneath your dignity you step into sight, confronting the two men. They stop, looking at you with startled and glancing back at the girl who sprawls face down on the bench.

"What's going on here?" you demand, putting as much sternness into your voice as you can. The men look at each other, then back at you, their faces full of guilt and worry.

"Senor, we were....uhh..." one of them starts, then looks back at the well fucked teen on the bench and shuts his mouth, looking back at you with fearful eyes. The other licks his lips, his eyes flickering as though he's contemplating running past you and trying to escape.

"You were **** this girl," you say harshly, seeing them flinch. You tense, expecting that this might get physical when the girl rouses herself.

"No....no they didn't **** me....I wanted it...." she moans, propping herself up and looking at you.
