Chapter 1: Getting Caught and loving it

It was a frustrating evening with my girlfriend at the movies. She had teased me mercilessly. She encouraged me to feel up her tits on the outside of her sweater, but denied me when I tried to reach inside.

After that she squeezed her own right tit with my hand and then pushed me away. We made out a little after the movie but got bitchy when I tried slipping my hand under her sweater.

The net result was that I came back home with the worst case of blue balls I’ve felt since I hit puberty.

I had hoped that by now I would be doing much more with her, but she’s taking it too slow for me. After two whole months of dating, not even getting to second base was frustrating to a hot-blooded, sixteen-year-old like me.

I got home around midnight, and usually by that time mom and my two older sisters would be in bed.

I was too horny to just go to sleep so, thinking that the coast was clear, I plopped on the couch in the living room after taking off my pants and underwear.

I opened my phone to my favourite masturbatory aid, a recent picture of my oldest sister in a skimpy bikini, with prominent nipples and very well defined cameltoe. I had taken that picture a few weeks earlier as she laid down to work on her tan in our backyard.

At eighteen, Louise was hot. Incredibly hot, even to me. Her big tits and wide hips framed her nicely pinched waist to create an incredible hourglass figure that had her own brother drooling like an idiot around her.

I was just about to cum when my sister, Louise, walked in on me. I was caught, as they say, cock-handed. Once I got over my shock, and noticed what she was wearing, I couldn’t help but resume stroking my cock while maintaining eye-contact with her prominent nipples, visible thru her see-thru top.

Few strokes later, I came, shooting string after string of sticky cum onto my own chest.

With a smirk, Louise turned and went to her room.

I woke up late as it was a Saturday and didn’t have anything in particular to do.

I entered the kitchen to find Louise pouring herself some milk for the cereal from the giant box that sat in front of her.

As I made eye contact, her smirk returned and I couldn’t help avert my eyes. Being caught jerking off to your own sister’s picture is embarrassing to say the least.

“Morning pervert.” Louise greeted me barely holding her giggles.

“Yeah, sorry about that. Where is everybody?” I said as I headed to the cupboard for a bowl for cereal.

“Mom and Jenny went shopping.”

As I put down the bowl and grabbed the jug of milk to pour some, Louise looked at me and chewed her cereal with a smile in her eyes.

As she swallowed, she asked “You always jerk off to your own sister, pervert?” She asked as I pulled the chair to her left and sat down.

Sigh! No avoiding that conversation.

I didn’t know how to answer her question. She was right. I was masturbating to a picture of my own sister!

“Well...”

“Well what?”

“Well, yeah I guess when my sister looks like you do.” It just came out of my mouth.

“Oh yeah? And how do I look exactly?”

“Come on. You know.”

“No, I don’t know, why don’t you tell me?”

“Well, look at you.”

“I look at myself plenty of time thank you. I’m interested in what you, my little perverted brother, see.”

“Ok, fine. You’re hot. You’re damn sexy. Happy?”

“Kind of.”

“You are?”

“Well, yeah. Usually brothers and sisters don’t find each other sexy and for you to find me sexy means I’m more sexy than average.”

“That’s an understatement.”

“How long have you been jerking off to pictures of me?”

“A couple of years now.”

“Really?”

“Really.”

I could see that Louise’s nipples were now hard. They were poking out quite a bit from her thin halter top. I wasn’t very experienced, but I knew enough to know that was a sign of being turned on.

Louise must be getting turned on by the idea of me finding her hot enough to masturbate to her picture. Maybe I wasn’t in too much trouble if I massaged her ego a little.

“Since I started getting boners, I noticed they’re hardest when I looked at you.”

“Oh my god! I did not need to know that.”

But it seems she did. Her nipples were poking out more now.

“I don’t know if you’ve noticed, but I always watch you come and go.”

“Oh yeah? What do you like most about me?” She was fishing for compliments.

“The way your big tits jiggle when you’re not wearing a bra.”

“Language buster. To you they’re breasts or boobs. Not tits.”

“We’re alone here. And when they’re like yours, they’re big beautiful tits that need to be appreciated.”

“Oh my!”

“Yeah. Does that bother you?”

“Not really. Well, you are my little brother, but you’re still a handsome guy, and your interest is interesting.”

“OK, as long as you’re not too bothered by my perversion.”

“I am, but not too much.”

I could see Louise’s thighs squeeze rhythmically. She was getting turned on quite a bit.

“The best view that I got was last night in your thin nighty. As soon as I saw your nipples I couldn’t help but cum and I came very hard.”

“I saw.” Breathed Louise with her eyes drooping a little.

The kitchen table was a small round one and Louise was close. So I reached over and before she could react grasped her closest nipple and gave it a gentle squeeze.

“Oh...”

And as if she snapped out of some kind of trance, she reached for my arm and very slowly tried to move my hand away from her exquisitely hard and long nipple.

I resisted and gave her nipple a series of gentle squeezes before letting go of it and allowing her hand to move my arm away.

“What did you do that for?”

“Sorry, I really couldn’t help myself.”

She didn’t say anything, but she seemed to be struggling to control her breathing.

“Don’t be a naughty boy Jake.”

“I’m not a boy anymore. I’m sixteen and I’m six feet two already.”

“You are, but you’re still my younger brother.”

“And you’re my drop-dead gorgeous big titted sister.”

“Still.”

“Still nothing. I can’t help it when you’re this close. You’re lucky that I’ve been able to control myself around you. You have no idea how many times I just wanted to just grab you and ravish you.”

“Oh my. That bad?”

I reached over and caught her nipple again and started squeezing in and rolling it between my fingers gently. Her mouth opened and her eyes closed. She didn’t pull my hand off and didn’t resist. Louise was now beyond turned on it seemed. Trying to get out of trouble seems to be leading me into bigger trouble.

When she didn’t resist, I reached with my other hand and grasped her other nipple and squeezed and rolled in tandem with my other hand.

A minute or so after, I realized that Louise wasn’t going to stop me.

So I reached behind her neck and tugged on the knot that held her halter top up while maintaining pressure on her right nipple.

As soon I had it undone, I pulled the strap down pulling her top below her left nipple. I seemed that Louise was in a world of her own and didn’t seem to realize what I was doing.
