Lie (or at least try)

"Of course it does!" you say, unconvincingly. Your penis is twitching and dripping precum, but you hope desperately that she'll believe your lie.

Astrid raises an eyebrow. "Oh really? And what would it take to see your itty bitty penis get a little bigger?"

You groan, knowing this can't possibly end well. Your squirming causes your penis to bounce up and down, which makes Astrid giggle.

"What if I got naked, Sam? Would that help? C'mon, I want to see this big dick you're telling me about!" Astrid winks at you, and reaches for the hem of her shirt.

"Astrid... please..." you moan, but she doesn't listen. Instead, she tosses her shirt off, and stands proudly naked in front of you, with her hands on her hips. Then she frowns.

"Hmm... I don't know Sam, your dick still looks pretty tiny! Maybe you just need to see more of me?"

You let out a soft moan as she turns around and wiggles her butt, then spins back around to gauge your reaction. Your penis is on the verge of exploding, but you can't take your eyes off of Astrid's pale, naked body as she stands in front of you, her face cheerful and cruel at the same time.

"That's so weird," she says with a giggle. "I'm doing everything I can to help you out here, but you still have an teenie little penis! Hmm... I have an idea!"

Astrid claps her hands together with excitement.

"I just need to touch it!"

With that, she runs right up to you, and reaches one finger out towards your rock hard penis. Looking you in the eyes, she flashes you a quick wink before running her finger gently up your shaft.
