Try to seduce Ben. Maybe he's really afraid he'll like it.

You stand and walk towards Ben. "Oh I don't know. I mean, how do you know you won't like it if I try something?" Before he can react, you reach down and gently grab his crotch. You lightly squeeze your hand, and you feel your palm lightly grind against his denim-covered cock. You smile as his manhood stirs slightly.

Ben gasps and takes a step backward. "I can't believe you just did that! I'm not gay!"

You grin and summon your most seductive voice. "Sure you're not. Do you know how many straight boys I've heard say that just before they feed me their cum?" It's a lie, of course. You've never seduced a straight guy in your life. But Ben doesn't know that.

Ben stutters. "Well, that's them. I'm not gay." But a glance at his jeans tells you he's not so sure.

"Funny, you're cock seems to be less certain of that." You walk up to him again and place a hand on his shoulder. He tenses under your touch but he doesn't immediately try to break free. "Relax. There's no need to make up your mind right now. Just see what happens and how you feel."

You can hear Ben's slightly labored breathing. You wonder what to do next.
