My jaw fell with it.
Sam was now standing in front of me in just a red thong that consisted of red string and a patch of lace between her thighs. Speechless, my eyes roamed up and down her body. Sam was breathing fast, her small tits rising and falling with each breath.
Her stomach was smooth and flat, and her hips flared out just enough to give her slender figure a nice shape. I looked at her soft inner thighs and with a start realized I was hard.
"Do you like them?" Sam cupped her tits.
"I—"
"I know they're not that big." Sam's thumbs caressed her nipples. "But they're all yours."
"They're ..." I swallowed nervously. "They're beautiful." Looking up at her, I said, "You're beautiful."
"Really?" To my surprise she blushed. "You think so?"
"Yes." My fingers trembling, I reached out and placed my hands on her hips. "Damn, you look good."
"Don't look like your best friend now, do I?"
"No, that's for sure." I stared at her nipples. "Wow, they look good."
"So what do you say, Justin? You ready for your first time?
"I—" I looked down between her thighs, imagining what was beneath the thong. Sam was really offering herself to me.
My mind filled with images. Sam on her back, her legs spread, and me lying between them; her on her knees between my legs, her beneath me, her legs wrapped around me. My cock was now throbbing and I was starting to sweat.
Sam was still holding her and reaching for them, I whispered, "Yes."
"Hold on." Sam caught my wrists, holding my hands inches from her tits. "Just because we're doing this doesn't mean I want to feel cheap about it. You can have anything you want from me, but you're going to be good to me."
