"Mark…" She mumbled my name against my mouth, her tongue playing along my lips, and I slid one hand in through a mis-buttoned gape in her blouse, my finger rubbing her nipple and making her moan and wiggle some more. My other hand was ticking her zipper down a little at a time, and her little hips wiggled on me, driving me to distraction.

"Wait," she whispered as I slid my hand into her jeans, heading for the promised land. "No, wait, don't…"

I sighed, moving my hand to less offensive territory, sliding it around behind and under the waistband of her jeans. Her skin was soft and she relaxed, kissing me again as I inched my way further down, seeking the top band of her panties. Surprised, I didn't find it as the rounded curve of her ass fill my hand.

"Angel," I murmured, confused, feeling my way over the soft globe of her behind.

Then I found it-a thin band of material running up the crack of her ass. "Are you wearing a thong?"

"Yes," she admitted, her smile shy, her cheeks pink, her blue eyes looking out at me from under those blonde bangs like she’d been keeping a secret-and she had! "It's more like a g-string kind of a thing…"

"Oh my God." I said, grinning, grinned, remembering my comment last week about the little cotton panties she wore, like a little girl, with all the days of the week. "Let me see!"

She giggled as I tugged on her jeans, batting at my hands, but letting me make quite a bit of headway as the denim slid down her hips.

"What color are they?" I groaned when she moved off of me to stand next to the bed, realizing what this meant. She’d been planning on me seeing her in her new underwear all along! My cock twitched at the thought.

"See for yourself." She gave me a coy smile and turned her back to me as she wiggled the rest of the way out of her jeans. Down, down, down her hips they went, and my eyes traced the thin black strap down the crack of her ass, glimpsing where it disappeared between her thighs. My cock jumped when I saw the crotch of the thong, a little darker than the rest.
