(I wrote this chapter for all those readers and friends who liked "Fun with Sister in the Car" and asked to write more about Jack and Teresa. I owe them an apology for taking so long to write a second chapter. I'm very bad at finishing what I started but I promise I would be more active in completing my unfinished stories. I appreciate all your comments and support and I wish you would like this second chapter)

It was one of July's beautiful afternoons; the sun was warm, the skies were clear, and my folks were in a vacation, leaving me and Teresa, my little sister, alone for the weekend.
To tell the truth, I didn't mind staying home with sister at all. As a matter of fact, I was excited. After that incident in the car two months ago, I became obsessed with my sister. I spent my time spying on her changing clothes, fantasizing about her in naked positions, masturbating with her underwear, sniffing her used panties and thongs, but nothing more. She became rigid and less playful after what we did two months ago, and that drove me crazy.
Teresa invited her best friend, Jennifer, to spend the day with her. I knew Jennifer since she was a kid. She had blonde hair and blue eyes, which she used to hide behind red glasses. After she turned eighteen, she grew large boobs and round curves all over her body. I would have a crush on her, if my mind was not busy with my little sister at that time.
When Jennifer arrived, she went upstairs inside Teresa's room and locked the door behind them. When they came down, they were both wearing bikinis and carrying their towels. I had a difficult time gathering my wits and pretending to be cool, when they walked past me in these skimpy clothes, heading outside, towards our swimming pool.
I sat in the living room, listening to their giggles and cries which reached me from the yard. You need a great deal of self-control to prevent yourself from standing and staring through the low window at these two gorgeous girls, playing outside at the pool, behind you. Unfortunately, I lacked this virtue of self-control. Just after ten minutes, I gave up to my lust, dropped the remote control from my hand, and turned around, rising on my knees, to stare through the window on my sister and her friend.
Jennifer was sitting on the pool's edge; talking to my sister who was inside the pool. Her legs were half-way inside the water. She looked cute in her red small glasses. Her long golden hair was pulled back into a pony tail. She was wearing a very slim two piece red bikinis which hardly carried her heavy bosom. She looked like a goddess relaxing on the pool's edge, but my attention was given to the one who was inside the pool, to my sister.
Jennifer was beautiful, but Teresa was sexy. Everything my sister had or did was sexy; the way she looked, the way she walked, when she ate a hotdog or licked her ice cream, she was always sending me into lustful dreams, just by watching her hanging around.
Teresa was wearing a black, one-piece swimsuit, covered with pink and green stripes. Her short hair was wet and dripping. Her body was smaller than her friend. Her tanned skin was glistening under the sunlight. She swum towards her friend, then climbed outside the pool. The bottom of her wet bikini was stuck between her ass cheeks, showing the configuration of her cute, firm ass. She tugged on her bikini to readjust the narrow fit. I slipped my hand inside my shorts and started stroking my hard penis. If only I could see her naked again..
Then, I had this crazy idea; I ran towards my parent's room, and pulled out a drawer; the one my father keeps his keys in. Bang... I knew it would be there, a spare of the master key, the one my father used to open all the doors inside the house. This was all I needed to see my sister and her friends naked, this and a little bit of courage.
I locked all the doors in our house; Teresa's room, my room, the kitchen, the bathrooms, the main door they used to get to the yard, every single door. Then I sat down in the living room, under the same window, trying to figure out what should I say when my sister and her friend discover that the main door was locked!
After what looked like two hours of endless waiting, my sister and her friend wrapped their bodies with their towels, and walked towards the main door. My heart was bounding inside my chest. I heard the forceful shakes of the door's knob, and my sister's voice talking to Jennifer: "Damn, what's wrong with the door!" Then, a violent knocking on the door sounded all over the house..
"Jack, are you still there?" my sister shouted from the other side of the window. "Stick to the plan Jack, stick to the plan", I needed to remind myself.
I rose on my knees again, to see Teresa and Jennifer wrapped in towels, standing below the window.
"What's up, girls?" I tried to sound cool despite the suspicious look Teresa was giving me.
"The door is locked"
"I know"
"You know!"
"Yes, I'm the one who did it"
"Reeeeeeeally!" Teresa looked puzzled and angry. Jennifer giggled behind her.
"Open up the door, idiot"
"Not that easy, sis"
"What do you mean?"
"You need to fulfil some conditions, first"
"You have some conditions to open the door for us!"
"Yup"
"I'm gonna kill you when I get inside"
"Then, I'd better keep you locked outside to protect my valuable life"
"Open up Jack, this isn't a game"
"Not before you do what I request from you"
"And what do you want, thick head?"
