MK picked up the microphone and took the glass bowl back to the stage. I saw a look of concern on my sister’s face as she conferred with the other sisters on the stage. While they talked, I thought about bailing. But just maybe, MK could ride me without us having actual sex. I watched my sister walk into the Bull Pen and talk to the owner. Then she came over to me.
“Hey Squirt, I can’t back out of this, or it’ll look bad for the sisterhood. The new members might think I’m too scared to ride this damned bull. Nobody knows you are my brother, and I ain’t tellin’ ’em. That first rider was danged hot! I need to make this look good. I’ll find a way to make it up to you. I promise.”
She gave me a soft but sensual kiss. I could smell beer on her breath, but she didn’t appear drunk. My sister moved the stool to the rump end of the bull, right beneath my head. The owner offered her a condom, but she refused. At least I didn’t have to worry about penetration. But what happened next was almost as bad.
MK reached under her T-shirt with both hands and in a torrent of flailing motion, somehow removed her athletic bra. She tossed it to one of her fellow sisters. MK still had her T-shirt on as I looked up at her, upside down, from my position. Her unsupported breasts looked massive! She leaned over and lowered her breasts right onto my face, mashing and rubbing them against me.
She whispered, “Admit it, Squirt. You’ve always wanted to know what my breasts feel like.”
Her boobs completely covered my face, leaving me in total darkness. She was right about my secret desire, and I was loving it. Grabbing loose handfuls of my bull costume, MK pulled herself up and clambered over me. As she slithered down my torso, the pink fabric of her T-shirt gave way to the mixed colors of her cowgirl skirt. After one more pull, she stopped in a perfect sixty-nine position. Since MK was taller, I knew she was looking right at my erect cock, while I stared at her bare ass, sans her red panties.
Two magnificent ass cheeks lay before me, both perfectly round and firm looking, bisected by a deep canyon that only partially revealed its depths. Pulling her thighs slightly forward, MK raised her ass up and shook it like a rattlesnake, right in my face! I got a quick glimpse of her pussy lips, but it looked like MK had slammed that gateway shut. The crowd loved her rattlesnake shake much more than I did. But at least we weren’t having full-on sex.
Suddenly, the mechanical bull started moving. MK grabbed my cock and began stroking it, but thankfully did not put it in her mouth. The bull operator knew how to please the crowd, and started a simple rocking motion from front to back. The motion took MK slightly forward, then rocked her back. Lifting my head, I was in awe of the spectacle.
The bull operator increased the intensity of the bull’s motion. As MK rocked further back, her ass bumped right against my face. The crowd went wild. There was nothing MK could do. As the bull rocked, gravity and momentum kept her ass mashing against my face. With her body lying on top of mine, she could barely hang on as is. If I pulled my head back, the crowd would be disappointed. I didn’t care about the crowd, but I didn’t want to disappoint MK. I took it like a man. A happy one, at least.
Although she couldn’t see me, I knew MK could feel what was happening, because I could see a sheen forming between her tight pussy lips. She released my cock and pushed herself up with her hands. But all that did was settle her ass right on my face! I couldn’t believe how well my face fit into the cleft between her ass cheeks! The bull operator must have been annoyed by what MK had done, so she added a kick to the mechanical bull’s rump. MK’s ass rose up into the air about four inches, then slammed down. Her ass cheeks instinctively reacted by trying to clamp themselves onto my face. I was getting punch-drunk from the pounding, but the crowd roared.
Taking advantage of the mechanical bull’s kick, MK made a timed leap forward and landed about a foot further down my torso. Before the surprised operator could stop the bucking motion, MK’s ass had already reached my stomach. I saw MK leer at the bull operator, who switched to a gentle rocking motion. MK swung her left leg over the bull and sat side-saddle for a moment, before swinging her right leg over the bull. When she finished, MK was facing me. She looked none too happy.
MK’s legs spread apart on the bull, and with her cowgirl skirt having ridden up, I got my first clear view of her exposed pussy. A small tuft of light brown hair hung over her clit, but she was otherwise smooth and hairless. Her outer lips reminded me of the pit of a freshly opened avocado, perfectly smooth, with a gentle sheen lingering from earlier in the evening. But they were still pressed tightly together, offering me no hint of what lay inside.
MK pushed herself back up and removed her pink T-shirt. Seeing her bare unconfined boobs, the operator made the bull rock from side to side, swaying MK’s breasts in a like manner. I just stared. with my mouth open. MK’s hands moved up and cupped her breasts, massaged them, and teased her nipples. Her efforts drew loud cheers from the audience, along with tingles in my cock.
MK leaned forward, flattening her body on mine, and made a big show of licking the exposed part of my face. She lifted her head slightly and whispered, “I’m behind in style points. I’ve got to turn up the heat. No matter what happens, I want you to know I love you. And don’t you dare squirt, Squirt.”
I feared what was coming. MK pushed herself up again, rocking side-to-side, wriggling her butt. She began a slow backward butt walk back toward my cock, her wonderful boobs swaying until her ass cheeks reached my erect cock. Both hands pressed on my stomach, and I saw her hips rise. I couldn’t believe she was going through with this! She closed her eyes. I wondered if it was because of her shame, knowing what she was about to do. I know I felt shame. I hoped she didn’t think of me as her brother at this moment, but rather, as a fake cock waiting for her to ride.
Her pussy hovered over my cock, and I saw bits of her darker inner lips dangling down. She was being pushed into this by the crowd and was getting excited. She paused and did not lower herself. The bull operator sensed her hesitation and switched the bull to start bucking up from the front. I could see MK trying to fight the movements of the bull, but when the front of the bull kicked up, it pushed the tip of my cock into her pussy. I saw her gasp but heard no sound other than hoots from the crowd.
Mk’s pussy reacted to the sudden intrusion by squeezing my cock for a moment, as if trying to keep me from entering further. Four more times the bull kicked up, and each time I went deeper into her. I could feel myself spreading her lips and opening up her inner tightness as my cock slowly disappeared into her wet tunnel. Knowing it was hopeless, MK gave up fighting and settled her full weight on me. I was all the way inside and felt her wet puffy lips press against the base of my cock. Her pussy clamped and squeezed, and I felt her inner muscles rippling against me as if hoping to push me back out. I looked over at the bull operator and saw her smiling. She must be pleased, because she stopped the bull from bucking, and switched to a slow, gentle ride.
MK’s soft, wet, and velvety pussy felt far better than anything I could have imagined. The bull’s motion had slowed, but MK’s body kept shifting and rocking. Her vagina gently pushed and pulled on my cock as it moved inside her. It was so erotic. So sensual. We were together, brother and sister, sister and brother, moving as one body on the mechanical bull.
MK looked at me and our eyes met. She gave me an intense stare. She was getting into this, driven by the signals being sent to her brain from her pussy. Timed with the bull’s movements, I heard her gasp, “Uhhh! Uhhh! Uhhh!”
I fought to hold my orgasm back but I was so close to exploding inside her. My cock was throbbing and battled with me for its release. I reached for the leather strap around my stomach, hoping to loosen it enough to at least turn onto my side, but to no avail. My arms flailed and I desperately reached my hands towards my sister. My eyes pleaded with her. She smiled, and at that moment, I knew she wanted me as much as I wanted her. A nod of her head told me it would be OK. I quit fighting and laid back.
MK’s eyes glazed over, her head tipped back, and I felt her vagina rippling with her orgasm. I timed my thrusts to the motion of the bull, rising and firing a load into her pussy.
“Oh, Squirt!” cried MK.
“Squirt! Squirt! Squirt!” yelled the crowd. Their chants did not amuse me.
I kept pumping my cock in and out. “Ahhh! Ahhh! Ahhh!” shouted MK. She had left me, had left the bull, and was floating above both of us, lost in her own orgasmic world.
“Yee-Haw!” yelled the crowd.
The operator slowed the bull down and it came to a stop. My cock was still inside MK and I felt her aftershocks quaking against me. I felt odd, almost like I was spent, and wondered if I had anything left for the third rider.
MK spread both arms wide, showing off her incredible breasts, and yelled out, “That’s how a sister rides her bull!”
Her words had a double meaning, but only to MK and me.
Breathing hard, she whispered, “I know some way I can make this up to you, Squirt.”

Ready Rider Three
**********
As the owner cleaned me up, my sister put her T-shirt back on, but not her bra. Her sorority sisters tried to help MK walk, but she would have none of it. Making her wobbly way out of the Bull Pen, she rang the cowbell and walked over to the stage. Reaching into the glass bowl, she picked out the name of the third rider, “Emma Davis!”
I remembered that name from earlier. It was the redhead who asked MK about me! I heard the clomp, clomp, clomp of real cowgirl boots approach, then heard her speak softly with the owner. When they finished, Emma came up right behind me and I strained to get a look.
