Tell her the truth

You think of lying, as the embarrassment takes over your body right now. How could Daphne put you in this position now? What was her game for this? Did she really know he had a huge crush on Sarah or was she just bluffing to convince her? If you would tell her right now, it might create a huge rift between you two. You would never be friends again, and your chance might be completely blown.

But on the other hand, if Daphne was bluffing, and she had a brilliant plan in mind, you should probably go along with it and tell her that you're in love with Sarah. No matter the outcome, you could always tell her the truth of the bet later, and say this was all just a part of the bigger operation.

'Yes, it's true,' you say. 'I've had a huge crush on you for almost a year now.'

She looks extremely shocked at this news. 'Robbie... why didn't you tell me? Ask me out or something?' she asks softly.

'I... didn't want to ruin things between us...' you answer meekly.

'But Alice always told me that you didn't like me!' she says, protesting. 'And she said... you had a tiny cock...'

'She said what?!' you say, exploding. 'That's not true at all!'

'Well, I can attest that both those things are not true,' Daphne chips in. She holds her hand next to her mouth, like she's telling a secret and says; 'He's huuuge.'

Sarah hides her face behind both her hands. 'Oh my god!' she shouts, distraught. 'You like me?! You are always acted so different towards me! I just thought that's because you hated me!'

Your anger builds. Why would Alice paint you in such a bad light, after being best friends for so long, sharing so many intimate moments. You thought she loved you. Now she turned out to be a manipulative bitch behind your back. You make a mental note of confronting her about this later. Or have revenge of some kind.

'Of course I don't!' you shout, just as distraught. 'Alice knows I have a crush on you!'

'This is so awkward...' Sarah says. 'I don't know what to do with this...'

'I do!' Daphne interjects.
