I couldn’t help but contemplate what she thought this was. It was just five days ago that I laid into her for not defending me in front of her friends, but now we were sitting on the sofa like I had with Tess. My girlfriend, Tess. Ava was my sister, and not even one I held in the highest regard! While I did fuck her senseless once, and fully planned to do so a few more times, we would never be lovers. Which she had to know as well. So, why was she behaving like this?
Remembering the way I fucked her, my thoughts drifted to the box of toys I had stored away in my desk drawer, and to the plan I had hatched for her. That, in turn, caused my dick to grow in anticipation. Suddenly, I heard a half suppressed moan coming from Ava, as I felt her squirm a little while her grip on my arm tightened. I looked down, only to realize that I had unconsciously started to trace my middle finger in circles around her now hardened left nipple. It visibly protruded from the unnecessarily tight tank top she was wearing, and simply invited me to just keep playing with it. So, I did.
The movie had about eighty minutes of runtime left at that point. I spent the entirety of them playing with Ava’s body, stroking, tickling, pulling, and a few times even pinching her hard nipples, effectively exploring her various erogenous zones while feigning ignorance as to what I was doing, and resisting her attempts to pull my hand in between her legs. I wanted her to be as randy as possible for my plan to work, while simultaneously demonstrating that I was the one in charge when it came to sex. After a while, I allowed my hand to wander towards her waist to grab the bottom of her top, and pulled it up over her breasts, exposing them for better access.
I learned that she was quite sensitive around her belly button, heard her purr when I lightly scraped my fingernails over the inner side of her forearms, and she was mewling when I nibbled her earlobe. By then she was stroking the inside of my thigh, no doubt encouraged by the massive erection my sweatpants couldn’t hide in the slightest. I did not allow her to stroke it for extended periods of time, however, as I was seriously worried I would just come in my pants after stimulating her tight body for so long. Whenever she tried to pull my hand towards her steaming mound, I instead let my fingernails drag along the inside of her thighs, like I did with the inner side of her forearms before, only ‘accidentally’ touching her soaking crotch in passing.
The smell of her arousal was thick in the air. By the time the credits started rolling over the TV-screen, she had long forgotten about the movie entirely. All of my probing had simply driven her crazy with need, and I could hear her consistently letting out wanton and frustrated moans. Her breath had become ragged, as she rubbed her thighs together.
She had readjusted her body once again, so her naked breasts were rubbing against my torso, her face buried in the side of my neck so she could kiss and suck on it with such want, I was sure I would find a few hickeys the next morning. She was continuously and somewhat forcibly rubbing my groin by then, feeling the thick and rock hard piece of meat in my pants.
I smiled at that development. From what I witnessed in my time living with the family, I knew they were all used to having sex multiple times per day. Ava had now gone completely without another person’s touch for two days at that point. When she finally couldn’t take it anymore, she lifted her face up so her lips were close to my ear, and sensually whispered in a voice that was dripping with sexual need.
“Please, Tim! I need you! You have me sopping wet from your teasing! Please, please, I NEED you to fuck me!”
“Oh? Is that so?”
I let go of her nipple and let my fingernails scrape down her stomach and belly button, causing her shoulders to tremble. Then I moved them across her lower abdomen to her inner thighs, causing them to lightly jerk. And finally, I cupped her crotch with my hand, causing her to let out one long and loud moan while pressing her face into my neck. She didn’t exaggerate! She was literally soaking wet! I didn’t even push my hand into her pants, just touched her from outside them, and they felt like she had peed herself! Surprised, I lifted my hand to inspect it, and could see the moisture glistening on my palm and fingers. Acting like I was trying to decide what to do next, I placed the wet fingers in my mouth and sucked her juices off them. This clearly just made it worse for her, and she switched tactics.
“Mom told me about what you two did.” she proclaimed, and I didn’t immediately understand where she was going with this. But when she continued, I understood fully. “Please, Babybrother, don’t you want to fuck your big sister as well? Mom was giving you the love you missed out on. I should’ve been there for my little brother, but I wasn’t. Take me now, Babybrother! Use your sister’s body! Let all your frustrations out and pump all that anger I deserve inside me! Please!”
Apparently, Claire had told her about the night we spent together, not skimping on the details of how I reacted to her. Especially how I reacted when she called herself ‘Mommy’. Now Ava was doing the same by playing up the incestrous aspect of our pending coupling. I leaned over, wrapped my arms around her, and pulled her body onto mine.
As soon as her butt came to rest in my lap, she started gyrating her hips to grind herself against my hard cock. She did so as best as she could, with her back turned to me and my arms holding her in place. I grabbed both of her thighs and roughly pulled her legs apart so she was straddling me. Then wrapped my left arm around her upper body, trapping both of her arms to immobilize her, and placed my right hand between her legs. I lightly kneaded her mound in a way that would tease a possible release, but would never be enough to drive her to a climax.
“I don’t know.” I mused. “It’s true, you were a bitch to me. So, tell me, Princess. Why should I do something to make you happy, after you spent so much time attacking my own happiness?”
I increased the force with which I was massaging her sex, while once more nibbling on her earlobe, just so she wouldn’t think that I had told her off. Once again, a needy moan escaped her lips.
“PLEASE! I’ll do ANYTHING for you, Babybrother! I NEED you!” She was now almost shouting while her body squirmed in my lap.
“Anything? Really?”
“Yeeeees! Please!” she breathed.
“But this seems unfair, Princess. Using you for my pleasure sounds like something people would do for revenge, but let’s be honest here ... it feels like you want to be used. So, in reality, I would just do you a favor, wouldn’t I? When was the last time you did anything for me?” Hearing this, she let out a frustrated mixture of a mouselike squeak and sob. “So, what else could I do to you, to make up for the years you treated me so badly?”
“ANYTHING!” she immediately shouted. “I promise you, Babybrother, you can do anything! You can use every part of my body as you want, my body is yours! I’m yours!”
I had her. I smiled.
“So, every part of your body is mine. Are you sure about that? What about your pussy?”
As I asked that, the hand on her mound squeezed it, and she nodded vigorously.
“What about your mouth?”
As I asked that, I lifted the hand that was now soaked in her juices to her mouth, and she started licking and sucking my fingers clean while nodding again.
“And...” I started, moving my hand back between her legs, only this time, as she instinctively pressed her hips forward to meet my hand, I pushed my fingers underneath the elastic waistband of her pants. Then my fingers rubbed across her radiating folds before I finally pressed the very tip of my middle finger against her tight little brown hole without entering her. “ ... what about this?”
