My Sister the Sorority Cowgurl
This standalone story features characters introduced in my earlier story, 'My Sister at the Cowgurl Cantina'. Enough background is provided so that reading the earlier story is not required. I hope you find this to be a fun story, full of clever wordplay, along with a liberal dose of sex. Saddle up and enjoy riding with MK and her younger brother Colt, as they struggle to fulfill MK's fantasies at the University of Texas in Austin.

Jogger's Nipple
**********
I met my older sister, MK, early on Tuesday to go running on the University of Texas campus in Austin. Smiling when she saw me, she looked great! She wore a stretchy grey athletic bra that showed off her nice 34C breasts, along with pale yellow running shorts. Around her waist was a small fanny pack. Her wonderful long blonde hair was tied back in a ponytail.
"Hi, Stud!" she said.
I liked her new nickname for me. For years, she called me Squirt, and while I remained four inches shorter than her, our relationship changed after she rode my cock on the mechanical bull at the Cowgurl Cantina. We were exposed here, so I gave her a polite bro-sis hug. Afterward, I noticed erect nipples beneath her athletic bra.
MK said, "Keep your eyes open for a secluded outdoor spot where we can have sex. It'll look suspicious if I keep bringing you to my bedroom at the sorority house, and since I'm a senior, I refuse to hang out at your freshman dorm. Look for things like trees, shrubs, or the blind sides of buildings. Let's start running, Stud."
It was a hot morning, but when isn't it hot in Texas! I let MK drift ahead of me several times so I could watch her hips and the rhythm of her wonderful ass from behind. MK must have noticed me lagging, so she stopped beneath the shade of an oak tree. "I keep getting ahead of you, Colt. Do you need me to slow down the pace?"
I smiled at her and said, "Sorry, MK, just admiring the view."
MK came up to me, looked around, and seeing no one nearby, gave me a deep, intense kiss. After our lips parted, MK surprised me with a wicked-looking smile and said, "You take the lead!"
I began running, knowing MK was only two strides behind, ogling me. It was oddly mysterious and quite sexy. I wonder what cowgirls think of when they catch the eye of a cowboy. A sudden tingle rippled through my cock knowing I was not the one doing the looking.
"Turn left and go under those trees!" yelled MK from behind.
There was a sign for the LBJ Library, and after crossing a large lawn I pulled up under a stand of trees, then turned to face MK. The shade felt good, and the grove of large trees partially shielded us from the rest of the campus. I stood on a slope, with MK slightly higher than me. My eyes were at the same level as her breasts, and I could see her nipples were even more pronounced beneath her athletic bra.
"Damn you, Colt. My nipples are chafing from rubbing against the inside of my bra. It's called jogger's nipples."
"Don't you always have this problem?" I asked.
"Sometimes, when it's cold outside and my nipples are erect, but never when it's warm. Looking at your ass while you were running made this happen. Since you caused it, you get to fix it."
"How?" I asked.
"Soothe my nipples with your tongue. Be gentle, use slow licks, and hold your warm wet tongue against them. But no sucking."
I complained, "People will see us."
"This library has limited access and won't be open for another ninety minutes. This area of the campus is really quiet at this hour."
With a pouting face, MK added, "Don't you like my breasts anymore?"
How was I supposed to answer that? Using both hands, MK pulled up her athletic bra, held it slightly away from her body, and exposed her perfect breasts. Her erect nipples rose from darker areolas and did look irritated, which meant they were especially sensitive. MK has always been good at pushing my buttons. Taking advantage of the slope, I rolled the edges of my tongue inward, forming a small U-shaped valley, and held it under her left nipple. As I exhaled, my breath washed over her breast.
"Right there, Colt. That feels great."
The fear of someone seeing us made this even more erotic, not to mention the fact I was doing this in public to my sister. My cock rose to full attention. I let my tongue flatten and gave her nipple a slow lick. Then another, and another. I closed my eyes and concentrated on the sensations coming from the tip of my tongue, as it explored the shape and texture of her nipple. I felt every small bump and indentation. MK began moaning, and as she breathed harder, her breasts started to rise and fall. My cock was ready to explode, but standing in the open, I feared going any further.
As I stared at the erotic performance of her breasts, I saw two beads of sweat run down her neck and disappear for a moment beneath her bra. Releasing her nipple, I pulled back in time to see her sweat emerge below, dribbling down the valley between her breasts. My tongue intercepted the warm salty drops, preventing them from going lower.
"So good, MK. So tasty," I whispered.
"That's cowgirl glitter, Colt."
"Lift my breast with your fingers and check underneath for any chafing."
I did as she asked, and said, "It looks a little red, MK. Especially at the crease."
"Your tongue is more sensitive than your fingers. Lick the underside of my breast, then tease the crease with the tip of your tongue."
I cupped her left breast from below using my right hand, but her soft flesh overflowed my grip and left no room for my tongue to do its work. I brought my other hand up, then wrapped both around her breast, thumbs underneath, as if I were eating an overstuffed Breast Burrito. As my face moved closer, I could smell the lingering scent of body wash mixing with sweat from running.
I tilted my neck back as I licked beneath her warm, sensitive flesh. As my tongue moved toward her crease, her erect nipple poked me right between the eyes! I shifted her breast from side to side using my hands but had no other option than to mash my face against her breast, plunging me into darkness.
"That's great, Stud. Keep licking, right there!"
I felt MK's hand behind my head and she began stroking my hair. My tongue reached her under-crease and began swishing side-to-side. I could think of no words to describe the taste I was picking up from this world of perpetual darkness and warmth, except for 'Wow'. I pushed my crotch forward, bumping it into MK's knee, and began grinding against her. MK pushed her knee against me, my cock twitched, and a moment later, it erupted. I finished licking her crease, and then I backed away.
"Are you having fun humping my knee?" asked MK.
I smiled, then nodded.
"Now do my other breast."
