You're both big

Anna pulls away from the kiss to look down, her eyebrows raising at what she saw. Your 8-inch cock was already hard, Anna's teasing having made you horny. She held your member from underneath to get a good look at it. Tilting her head in thought, she blurts out, "You're bigger than I thought. I thought that you'd be as small as your friend Nathan there." She gave it another long look before letting go and taking a step back.

She pinches at the edge of her skirt, slowing lifting it. The first thing you see was her half-hard cock, something that tells you that she wasn't wearing any underwear. She gives it a wiggle. "Can I borrow your hand? I want to get it hard so that we can compare." She was already reaching out for your hand, grabbing and pulling it toward your cock. With both hands she manipulates your fingers around the shaft. Then she starts to stroke herself using your own hand.

You were unsure at first, but you played along. While limp, it was only a few inches, so you were confident you could win. And even if you lost.. looking to the side at the other couple, you could see Nathan in a trance, bobbing away on Beth's cock. He looked like he was enjoying it. Either way would be a win, probably.

Turning your attention back toward Anna's cock, you could see it stiffening. Four inches, five.. six. With every new inch, your confidence was fading away. But then it stops at around that eighth inch, and you paused, not sure what to do.

That's when you felt her step forward, her forehand leaning against yours as you both look down. She had her cock next to yours, the meaty shafts next to each other. You could see that your cock was a smidgen longer, your cock head pushing into her skin while hers was barely touching. But she was definitely thicker.

"Well," she starts, interrupting your thoughts, "We're both about the same.. what now?"
