He takes a... novel approach

"Mandy," you hear Sam say, but Mandy cuts him off before he can continue. "What the FUCK are you doing talking to me, Sam?! Shouldn't you be with that whore Cindy? You were practically drooling over her last night!" "Actually, no need to play along anymore," Sam replies. Huh? "It's done." There is a brief pause. Looks like Mandy is as confused as you are. "You said she blew you off. What happened?" Sam chuckles, before spinning his tale.

"She did. Initially. But I knew I'd gotten to her. After we talked, I decided to give it another shot. I broke the radio thing she gave me, and went back to tell her. I figured I could 'console' her, if you catch my drift. Well, she didn't answer the door when I arrived. I was just about to leave, but then I faintly heard her moan inside. I banged on the door, yelling her name, telling how everything had gone wrong. She was all red in the face and sweaty when she finally opened the door, and her hair was all tussled. It would be clear to anyone what she had been doing even if it wasn't for the vibrator on her bed, but there was that, too." "So you just barged in and fucked her? Just like that?" "Pretty much, yeah. She had been getting herself off fantasizing about me, obviously, so I didn't even have to say a word. She didn't even mention the GAME until I was lining myself up to fuck her. I just did it anyway, and that shut her up good." You hear Mandy laughing in the background. What the fuck is going on? Could Sam have been planning to betray you? "That dumb whore! She just let you fuck the brains right out of her, just like that?" "No, not quite. She must have noticed when I was getting close, because she demanded that I pull out. When I said I wouldn't, she panicked and tried to struggle. It was far too late by then, of course. You should have seen her face when I came in her! From a mixture of anger and terror to pure devotion in an instant. This magic really doesn't fuck around."

You are stunned, listening to this. Your mouth is moving, but nothing is coming out. What could you possibly say to this? Instead, you just listen to Mandy enthusiastically interrogating Sam further. "Why didn't you bring her? Like, I've been imagining all the things I'm going to make her do all week!" "She doesn't behave herself very well, yet. Oh, she'll do whatever I tell her, but the way she acts, people would notice if she were out in public. Might as well avoid questions like that, right? Not that there is anything anyone can do about it, but still. If you want, though, we can go to her. You can play with her as much as you want, then."

You can't make out anything else Mandy says, beyond a squeal. "I'll explain everything," Sam whispers, for your ears only, "Just trust me. Play along, and this will be over before you know it."
