Chapter 6
I slept well that night.
Maybe I should've felt more guilty. I mean, I felt a little guilty - I knew that what I'd done with my sister (
to
my sister) was wrong.
But god, it had felt so right.
And as I'd drifted off to sleep, the knowledge that my sister was in the next room, coated in my cum, submissive to me even in her slumber...
Yeah. The pleasure that gave me way outweighed any guilt I was feeling.
When I awoke, my first thought was that I hadn't given my sister any explicit instructions about what to do in the morning. Like, we'd managed to avoid attracting any suspicion from Mom so far, but if Kim emerged naked, covered in my cum...
I was pretty sure that she'd notice that.
Fortunately, when I sat down for breakfast (Mom has always insisted we eat meals as a family) my sister was freshly-showered, dressed in a simple t-shirt and jeans.
I don't even know if I would've noticed a month ago, but I was suddenly very aware that my sister wasn't wearing a bra. Like I said, she isn't the most busty of girls, so I guess she can get away with it...but as we ate, my eyes couldn't help but flick down to the sight of her nipples, clearly hard beneath her shirt.
When we finished eating, my sister got up to clear the table. "Thank you, Kim," Mom said while admonishing me with a glance.
On a normal day, I would've helped, but my sister's bralessness had caused a particular part of my own anatomy to get hard beneath my clothes.
I couldn't wait to be alone with her again. I couldn't wait to take things further. To have her suck me off, to buy a condom and use it with her.
I was going to fuck my sister. In any hole, anytime I wanted.
Well...not
any
time.
When I'm at home, I'm typically alone in my room. Sometimes I'll maybe be watching something in the living room, but...well, I have a computer in my room. A computer that has access to 'everything in the known universe', aka: the internet.
And so I never really paid attention to Mom's comings and goings. Like, I know she has a job, but she has a flexible ending time. Sometimes she's home before us, sometimes she's late coming back. But she never announces when she's going to be home (why would she?) and so - in accordance to my new rules - I didn't want to do anything with Kim unless I
knew
Mom wasn't going to surprise us.
As it turns out, Mom doesn't really leave the house much. And so despite the fact that Kim was ready and willing (way more than willing, in fact), it wasn't until Mom's movie night the next week that we got a chance to get together again.
Let me say that again: it was a
full week
before I was able to do anything more with my sister. Properly do anything, I mean. We hung out, I had her do little stuff for me (though even that was tricky with Mom around) and one night when Mom went to bed really early, I had my sister strip naked and let me take some photos of her.
That was probably too risky, but it was day four of not getting to fool around with my sister, and I was starting to climb the walls. I was rubbing one out every night, and all I could think about was Kim.
I had one of those super-secure vault apps on my phone (it required both a password and FaceID) and I figured if Mom woke up and walked in, I was still fully clothed and Kim could just hide until she left.
Only once we were done did I realize how poorly thought out that plan was. It relied on Mom not wondering why I was alone in my sister's room, not asking where Kim was, and not noticing the pile of clothes on the floor...
But when we were done, I knew it was worth it. I got almost two dozen pictures. It's funny, they weren't like anything else in my photo vault: like I said, my tastes lean towards the busty and blonde, not my flat-chested, black-haired, cute-but-not-hot sister.
The photos though...fuck. I'd bet that any porn site would have paid good money for them. My sister kneeling, a look of total submission in her eyes. Laying on her bed, legs spread, needy and wet. I had resisted the temptation to pull my cock out and get photos of Kim sucking it, but it hadn't been easy.
I hadn't realized how good the phone on my camera was until I took those pics. When I looked at them, I could practically smell her sweat, feel her tremble with pleasure, and taste her soft lips against mine.
It had been risky and more than a little dumb...but totally worth it.
And they got me through to Mom's next movie night. She looked at me a little funny as I helped her get ready, but I knew there was no way my mother was going to jump straight to "he's helping me leave so he can fuck his brainwashed, submissive sister".
Even though that's exactly what was going to happen.
I was ready. I'd bought condoms, I'd told Kim to do whatever women need to do to be ready for it. It wasn't her time of the month, and I'd talked Mom into seeing the new Christopher Nolan, which was meant to be good...but just way, way too long, giving us plenty of time.
Alone at last.
The moment Mom's car pulled out of the driveway, I made my way into Kim's room. She was kneeling, naked, repeating her mantras:
"I am owned by my master. I exist because he wishes it. Because it brings him pleasure."
"I will give my master pleasure. I will serve him with my body. I will do anything he asks of me, and I will enjoy it."
"My master is my world. He has the right to control me. He has the right to order me to pleasure him."
"To please master is my purpose. I wish to pleasure him."
I could have stood there and watched her all day, but I didn't know how long we'd have, and - after a full week of fantasizing about what we were going to do - I wanted to make the most of our time.
"Get on the bed," I ordered, and my sister obeyed without hesitation.
"Yes, sir," she said, a look of excitement in her eyes. I lowered my pants and pulled out the condom - we'd learned how to put these on in health class, and I rolled it over my cock.
My sister may have been willing to do anything I wanted, but I couldn't take any risks. Plus, rule number 1 - I had no interest in being a teenage parent, and knocking up my sister would be the very definition of doing harm.
I hesitated, not sure what position I wanted to fuck my sister in. On all fours? On her back? Bent over the bed? Standing up?
But as I stood there, contemplating, Kim made the decision for me. She rolled onto her back and looked up at me, silently pleading for me to fuck her. To use her. To let her bring me pleasure.
"Fuck," I moaned, under my breath, and Kim shivered with joy at the sound of my pleasure.
Without hesitating any further, I moved to the bed, positioned myself between her legs, and slowly pushed into her.
She gasped; I'd tried to go slowly, but been so excited that I'd moved faster than expected. It was happening. I was losing my virginity. I was having
sex
.
