"What have I gotten myself into with you two?" I asked, as I headed for the freeway.
"A wife ..." my sister said.
"... and a free-use side-bitch," Kelsey added.
I looked over at my sister. She was quiet - watching my face.
"I wasn't ready for you," I told her, "but mom and dad forced the issue - well - after you forced yourself on me."
"I know," she admitted, her lower lip trembling.
"Knock that shit off," I told her.
She dabbed at the corner of her eye and straightened her face up.
"You and I need to figure some shit out before I'm ready to even consider adding another person into the mix," I told her.
She grabbed Kelsey's hand, squeezed her fingers, and said, "She can wait. She'll be safe. Maybe she can look for somebody at class."
"Okay," I said. "No more 'side-bitch' talk for - let's say - a year."
"Okay," Renee said.
I looked at Kelsey.
"Okay," she said, giving me puppy-dog eyes.
"She and I can still be naughty, though, right?" my sister asked.
As I turned back to look at my sister, Kelsey curled her body around her. I shook my head and sighed. I didn't bother to answer.
I focused on the road. Soon, I noticed fingers creeping across my thigh. I turned and glared at my little sister.
"No," I said.
She stuck her lower-lip out in a pout. I noticed that Kelsey's hand was on top of Renee's thigh.
"Renee Irene ...," I growled.
She pulled her hand away like I'd breathed fire on it.
For the next couple hours, the two of them slept. They were curled together in a ball - an adorable ball. I glanced at their cute faces and their attractive bodies.
Two months ago, I'd been happily single - focused on graduating and making the transition from student to productive citizen.
My sister's 18
th
birthday had shattered that dream. Honestly, I wasn't mad at Renee. I'd already pretty much escaped the drama back home. She was still mired in it. Her birthday had just been the spark that ignited the tinderbox - which had turned into a forest fire when the police were called.
I thought back to all of the ways that my parents continued to choose Stacy over Renee. I was ignored or side-lined as well - I just didn't care as much. Ultimately, I was happy that I'd been standing there when it all went down - able to help my little sister finally get out from under that oppressive cloud.
I still wasn't sure that I wanted to be "married" but I couldn't argue the fact that it felt so good to have my cock buried inside of my little sister's vagina - especially as my jizz spurted into her. The thought of getting her pregnant didn't scare me - it excited me. I'm some kind of social deviant but I seriously refuse to consider my various forms of love for my little sister as anything unholy. I had peace about it.
Right now, honestly, my only hesitation, with any of this, was in leaving Mary in the situation she was in. The desperation in her eyes and voice made my heart hurt. If it came down to it, I would wrap my arms around Kelsey and maybe - maybe - even welcome her into bed with Renee and me - but I really wanted time to get things settled with my sibling before we complicated things anymore.
Why did it feel like I was being cornered into more and more bad decisions? I didn't blame the girls - or Mary. It didn't feel like they were manufacturing this. In fact, I felt like they had endured the hostile environment for so long that I had no choice but to get them out of it as quickly as possible - the moment I became truly aware of what they'd been going through.
I couldn't very well be mad at Renee for caring for Kelsey - no matter what form that took. I didn't want to be a part of it though. Well - honestly - I wanted to. What virile male wouldn't jump at the idea of two 18-year-old girls working together to pleasure him. Kelsey's promises had been lewd and brazen - and they made my balls churn - but I needed to get my head on straight first.
If the two of them were engaging in sex-play in front of me, this was going to be more than I could handle. Watching the two of them make out - or eat each other to climax? My cock was so stiff - just thinking about it - that it was hurting. I could almost smell my lust - or maybe my pre-cum - swirling around the passenger space of the car.
I needed to set firm boundaries and get them to stay in their lanes. The only way that I knew to do that was to offer rewards for achieving goals.
Two hours later, as I left the freeway, the girls began stirring. I waited for them to both be awake and alert and then I began my lecture.
"I'm not going to be able to endure the two of you being frisky in front of or near me," I told them. "All of your little antics have to take place in Kelsey's room and I don't want to know about them."
The two of them nodded.
"Kelsey is not allowed in my bedroom. If she gets enrolled, works hard, keeps her grades up, and finishes the semester strong, I will come to Kelsey's room and allow myself to be tied to the bed for one night. In the morning, you have to untie me."
The two of them looked at each other and giggled.
"We'll proceed, semester by semester and talk about any changes to the arrangement as a group."
"I promise to be a really good girl, daddy," Kelsey cooed. "You can even check my pussy every once in a while to make sure my hymen's still there ..."
