Probably not

Let's face it, most 18 year old girls aren't really into anal, even if they've tried it. And in the instance that she's never tried it, which is very possible, the truthful answer would be 'false'. So it makes sense to guess 'false'. Even if this girl is more slutty than you realized.

"False." Says Finch.

"True." Says the other guy, after a long pause. A murmur passes through the crowd.

"I can now inform you... That neither of these girls enjoys anal sex! Which come on, let's face it, is hardly surprising now, is it!"

A red condom falls to Finch's feet, but no purple condom arrives for the rival team. Which means, there's no way for them to continue unless one of them fucks their sister without a condom. Despite how awful this situation is, it fills you with a little hope. It feels like you're one step closer to winning this competition.

All eyes are on brother number three. He's gone a little pale, but his face is one of determination.

"I'm so sorry." Brother two says. "I'm so sorry." He doesn't reply.

"You could do anal, brother." Brother four points out.

"We just had it confirmed that anal would be an extra level of **** for her." He replies to that. "I can't do that to her."

"But what if she gets pregnant?!" Brother one squeaks.

"She won't. Chances are she won't." That's all he says, and then moves forward.

"The rule for creampies," the man above declares suddenly, "is that after orgasm, you must stay inside your chosen hole and slowly count to 50, before pulling out."

No getting away with spilling most of it on the ground, then.

Beside him, you move forward too, a fresh new condom protecting your cock. It makes the fact that he's not wearing one all the more highlighted.

For some reason, the thought of this poor fellow having to have unprotected, pregnancy-risking sex with his sister, helped you swing up into your second erection of the game. You try not to think about the implications of what fetishes this might be awaking in you.
