Chapter 2
The next few weeks went that way, I would go to school with her, and we would flirt while nobody was looking. Our nights consisted of pleasuring one another, and we were getting considerably better. It was our routine. Never let it go past oral sex. Life was great, now that I finally finished pressure washing everything. My father had calmed down and ungrounded me from any more hard labor. I was finally going to be able to play golf and enjoy my summer, now that summer school was over for Katie.
On our first official day of summer, we decided to layout, swim in the pool, and enjoy the sun. She dressed in a skimpy bikini that made her breast protrude out both sides, and her low-waisted thong showed off her round ass perfectly. She wanted me to enjoy her body as much as possible but have something on just in case our parents came home early. Even though it didn't stop her from sunbathing without her top on, trying to give me a heart attack. There's only so much I could take before my hard cock let my little sister know it was enjoying the view. I did nothing to hide it as it smashed into the fabric and forced a tent in my shorts.
"Do you need me to apply any more sunscreen?" I asked.
"No, thanks, babe," she said, as she pulled and twisted her nipples between her fingers, "I really just need your cock in my mouth." She sounded like it wasn't a big deal looking up, smiling at me, and showing me her eyes that hid behind her dark oversized framed sunglasses.
I ripped my board shorts down and let my cock swing free out in the open, and it was exhilarating. I had never done anything like that and would never even think about doing it at my own home. My little sister sat up immediately and suctioned her lips to the head of my cock, and started to slide her lips back and forth over the rim of my head while flicking her tongue. Her large breast jiggled as she began to stroke my shaft faster. I loved to watch her enjoy me in her mouth, and it was something she wanted to do for me. But, it was all for show. She now knew just how to get me off with minimal effort, with just three easy steps. Step one. Pull me into the back of her mouth, making sure to coat my head with the perfect amount of saliva. Step two. Apply just the right amount of pressure. Step three. Break out the magic wrist and only stroke up and down on the top three inches of my cock. Within a minute, I was blasting volley after volley onto her massive tits.
"All better?" She asked, smiling. Knowing damn well what the answer was, as she rubbed my cum into her breasts.
"Yes, baby. The best." I answered, and I took my seat next to her.
"Katie?" I said, a little too aggressive, as I tried to force myself to say something I wanted to ask her.
"Yes." Her eyes were looking a little worried.
"Would you like to...to go out on a dinner date with me?" Her blank face bored holes right through me. I couldn't see her eyes and began to think the worst almost immediately. Was this too much too soon? Why did you ask her that? I kicked myself.
"It's ok, just forget about it," I said, feeling embarrassed and sick to my stomach.
"No." She said. "I mean, not no, that I won't go. I would love to go on a date with you."
"You don't have to go. I understand. It's too soon. I get it." I said, getting up from my chair.
"Connor!" She growled back at me.
"I wanna go! I was... Just shocked that we could be able to go out as a couple."
"Wanna go tonight?" I asked, feeling better.
"Yes, I would love to."
"Awesome." I shot back and dove into the pool, trying to hide my excitement.
This was taking it to the next level. Of course, we had been pleasuring each other and expressing our love to one another, but this was different. We didn't act like a couple; hell, we couldn't. We kept our distance when our parents were home and didn't take any chances when they were awake.
I took my time getting ready. I made sure my boots were clean, my pearl snap was pressed, and my hair was styled just right. I was nervous when I walked into the kitchen. Luckily my mom was more worried about my little sister, than to notice my anxiety. We had told them we were going on a double date: the fewer questions we had to answer, the better.
"Please be careful, Connor." My mother said, putting both hands on the kitchen island as she glared at me. "Don't let anything happen to her."
"I won't," I said as convincingly as I could.
Hearing Katie's heels click down the stairs and through the hall let us know she was on the move and headed our way. The entrance she made was anything but ordinary. Her strawberry red lipstick that glimmered on her pouty lips was the first thing that got my attention. Followed by the short black V-neck dress that sparkled as she moved. It was form-fitting and clung to every curve on her body. The two three-inch straps that started just above the swell of her breasts and held the dress up were tied in a bow around the back of her soft neck. Keeping with the look, she was going for, her hair was pulled back into a low elegant bun with one curly strand on each side. She was beautiful, so much so that I couldn't even find the words at the moment to say anything. My sister, the teenage girl, was gone, and a woman now stood in front of me. How had I been so lucky?
"Katie?" My mother said, sounding concerned. "Isn't that a little much for a first date?"
"Oh, mom. Come on! Please don't badger me. I'm a grown woman." Sounding like it wasn't a big deal, and knowing she was way overdressed.
"Excuse me, young lady?" My mother gasped as my father just chuckled in the background.
"Mom, Connor is going to be right there. It's not like I would do anything anyway. I'm not a whore mother." She shot back.
"It's ok, Mom. I promise I will not let anyone put their hands on her," I said, trying to de-escalate the conversation.
"Ok, Connor, just please be careful." My mother responded, with tears in her eyes.
