"I'd like that." I said as nonchalantly as I could.
"I bet you would!" Ava said and began playing with the zipper on her hoodie.
I felt my pulse race as she eased it further and further down until I could see her navel. I was sweating and quite frankly staring. I'd been glancing at her bare breasts moments before, but this was much more erotic. Ava didn't seem concerned by her lack of a bra. It dawned on me that it wasn't unusual lately for her to not be wearing one when we hung out. She stuck her fingers in and held the zipper open a bit wider, revealing some more of her perky B cups. She pouted slightly as she looked up at me through her eyelashes, then quickly zipped the hoodie all the way up as she turned away.
"I think that's enough for now, don't you?" She said over her shoulder with a wink.
"Um, no?"
I started to say more but Ava was giggling so hard her face was turning red. I made a helpless gesture and she doubled over laughing. Since she was still facing away from me it gave me a great view of her ass in the tight yoga pants. Again, I'd seen it bare a minute ago, but ever-so-slight sheer quality of the stretchy cloth took my breath away. No panty lines, either Ava was going commando or... I reached out and pulled up the hem of her hoodie to reveal the back of a lacy red thong peaking above her pants.
"Hey!" Ava shouted, spinning around and slapping my hand away as she tugged her hem back down. She was red-faced and tried to glare at me. I held my hands out to the side and mouthed 'what?' with the most innocent expression I could. Her glare lost to a new bout of giggles, and I stuck my hands in my pockets as we smiled at eachother. Ava took a couple minutes to pat her hair back into place, sneaking smiles at me now and then.
"That was totally uncalled for." She said eventually, though she was still smiling at me and was toying with her zipper pull again.
"Well...okay, I apologize. 'Though your undies are sexy as hell!"
"Of course." She replied, then scowled at me. "Any other comments on my appearance?"
"Just that if you hadn't zipped up just then I'd have been in danger of drooling all over myself."
She studied me for a moment.
"Let's test that, shall we?"
Ava began unzipping her hoodie again and I fought to keep looking her in the eye. As her hand dropped past her sternum I couldn't help but glance down. Ava pulled the zipper back up a few inches and let it dangle.
"No more grabbing, okay?"
I nodded as she stretched, the zipper gaping open to reveal the curves of her breasts. She squeaked and grabbed herself just in time to prevent a nipple from slipping into view. When I managed to look away from her hands Ava was looking at my crotch and looking smug. I glanced down at the bulge there and felt myself blush.
"Boys are so weird." Ava said as she stepped over and lightly pressed herself against me.
I pulled my hands out of my pockets and hugged her gently, not copping a feel on her ass the way I usually did.
"So, what now...stud?" She asked.
