Alessandra, Patty's twin sister

"Hi, how may I help you?" I say to a black-haired girl who was dressed in a flesh-colored tank top and dark orange skorts.

"Mr Thomas?" she asked with an air of uncertainty.

"Yes?" I replied, trying not to stare at her nipple tips poking through the thin fabric of her top. "Please come in." I coudn't help but notice her striking resemblance to Patty. "You must be Patty's sister," I ventured.

She smiles and nods her head at the recognition. "I'm Alex," she says extending her hand. I shake it firmly noticing her firm probing grip.

"You look just like her except..." I mouthed my words and wished she had not noticed them. "What brings you here?"

"What's so different about me and Patty?"

"Forget it," I say. "Why are you here?"

"Please tell me Mr Thomas. It's important to me." She pleads. "What's so different about me and Patty? Please say it. I won't feel insulted. Promise."

"You really are as inquisitive as Patty. Well, it's your breasts. They're bigger." I notice a slight blush but she quickly regains her composure.

"Does that make me uglier?" she says while unconsciously covering her chest with her left hand.

"No, no." I answer reassuringly. "You're prettier." I say softly, hoping Patty couldn't hear.

"Do you want to touch them?" she asks, removing her hand.

I am taken aback by the question as my cock slowly hardens. I look at her and notice that her boobs have grown firmer as if trying to burst out of their confines. I also notice that she is staring at my crotch.

With Patty within hearing distance, I am not sure what to say.
