Kissing me on the lips in greeting became commonplace, usually just a peck but sometimes more. One time on Tuesday, she walked into my bedroom, rolled my chair away from my desk, climbed into my lap, and shoved her tongue into the back of my throat. I got so turned on that I grabbed her ass, stood up from the chair, and walked us over to my bed. We wound up hot and heavy in a makeout session on my bed, and she even grabbed my hand and shoved it up the inside of her shirt so I could fondle her boobs. A minute later, my hands were in the back of her shorts, grabbing handfuls of ass while grinding my erection into her pelvis. But the moment my hand started wandering around to the front of her crotch, Michelle abruptly tore her mouth away from mine and rolled off the bed.
Staggering almost drunkenly to the open doorway, she yelled at the top of her lungs, “LEX!!! Get in here! ALEXANDRA!!!”
Thirty seconds later, our big sister came racing into the room, eyes wide and darting around looking for danger. The use of her full first name had probably freaked her out. “What? What? What’s wrong?”
Still gasping, Michelle pointed back at me and managed to grunt, “I need you to fuck him. Otherwise I’m gonna fuck him.”
Alex snorted. Standing up straight and arching an eyebrow, she folded her arms across her chest and replied in a neutral tone, “Maybe I should stay right here then.”
“LEX!!!“
Laughing, my big sister started pulling her shirt off. “Fine, fine. Twist my arm, why dontcha.”
And that wasn’t the only time Michelle called in her big sister as a pressure release valve to “take care of me”. I’d pretty much stopped watching Pornhub by this point, what with spending all my time with one sister or the other. Michelle kept me at a near-constant state of arousal from our frequent makeout sessions, and at least twice a day I would find myself badly in need of sexual relief.
Not that I would go ask Alex to service me or anything like that. She was my sister, and my older sister at that. If SHE wanted me to come fuck her, that was one thing, but I was never really the aggressor and would sometimes get wound up with pent-up horniness waiting for the next time my gorgeous big sister graciously allowed me to violate her nubile body.
Thankfully, Michelle could usually sense when I was getting a little too wound up. Even though -I- would never ask Alex for sex, Michelle had no problems either calling for our big sister to come take care of me or yelling to Alex that she was sending me to her.
Once though, on Thursday, of my own accord I walked into the big bathroom in our parents’ room while Alex was taking a post-workout shower. Earlier that evening, Michelle had climbed into my lap after we’d finished our latest Sydney Cummings video, holding my head in her hands and cramming her tongue into my mouth. She even went so far as to remove her tank top and sports bra, feeding her nipples to me while I suckled on them like a ravenous baby. Michelle didn’t have Alex’s massive mammaries, but her perfectly shaped B-cups were just so... perky ... and her nipples were super-sensitive, to the point that my feasting had her creaming so hard she nearly came.
I sensed that if I really wanted to, I could’ve fucked Michelle that night. She was so turned on that she would not have resisted me. But I knew better than to cross that line without prior approval. “Whatever you’re comfortable with” had become a familiar refrain, and I had done my best to let Michelle lead the way. Tearing my mouth away from hers, I dumped her onto the couch cushion beside me and quickly stalked away to go upstairs.
Alex saw me enter through the transparent glass doors, took one look at the expression on my face, and beckoned me inside. But the animal inside me had already gone wild, and instead I yanked my big sister out of the shower, planted her flat on her back on the carpeted floor of our parents’ room, and slammed my meat sausage into her cunt in a single thrust. My big sister didn’t cum that time - I basically rabbit-fucked her until I pulled out and blew my load all over her tits and face, not that she minded. Alex pulled me into the still-running shower, we both cleaned up, and then we went back to her bedroom so I could make it up to her.
An hour later, Michelle fell asleep with me spooned up behind her, my left hand extended across the mattress beneath her pillow and my right arm hugging her closely. She’d pulled my right hand beneath her pajama top so that I cupped her left breast in my palm. We both were happy.
“You’re smirking,” I commented with a scowl on my face.
“Because I’ve got you right where I want you.” Michelle replied confidently.
“I’m not in check yet.”
“Emphasis on the word ‘yet’.”
I sighed, surveying my options. She’d caught me in a trap, her knight in position to take either my queen or my rook. I couldn’t save both of them, so the obvious move was to get my queen out of danger, accept that she’d take my rook, and plan accordingly. Ordinarily I would have done just that, except for Michelle’s damn smirk. I knew her, knew the way she played. She didn’t have a great poker face, which told me she was smirking because she had seen something I hadn’t noticed yet. Somehow I knew, just knew, that if I saved my queen and gave her the rook, it would somehow lead to my final defeat.
I REALLY didn’t want to lose. It was a Saturday evening, and Michelle and I were winding down the last part of our day. We’d already done our workout and showered, the plan was to go to bed after this, and I didn’t want the sour taste of defeat in my mouth while trying to sleep.
And yet, I couldn’t sacrifice the queen so easily. So I stared at the board, rubbed my chin, and stared at the board some more, trying to figure out what the hell she was going to do.
“Tick, tock, tick, tock.”
“Gimme a minute.”
“I’ve given you five minutes already. Maybe we should start playing with a clock.”
“Hang on, hang on.”
“Time to put up or shut up.”
“Chelle.”
My little sister sighed. “I’ll give you thirty seconds to make your move or I won’t let you hold my breast as we fall asleep.”
I blinked twice and promptly saved my queen.
Michelle laughed and made her next move. Two minutes later, she checkmated me.
Growling, I rolled my eyes and started resetting the board. “Another round?”
“Didn’t we say we were going to bed after this?”
I lowered my eyelids and growled. “Another round.”
“Sure, fine.” She was smirking again. “Hey, does this mean I can now threaten to withhold sexual stuff in order to get you to do things for me?”
“We’re not really doing ‘sexual stuff’ yet,” I pointed out, complete with finger air quotes. “Other than the boob thing, you’d have to threaten to stop ... what ... cuddling with me at night? Kissing on my bed during homework breaks? Grabbing your ass in the kitchen? All of those things I think would hurt you just as much as hurt me, if not more.”
Michelle’s eyes flashed something dangerous, and she intoned quietly, “Maybe I should give you another blowjob, just so I have something to ‘take away’.”
