Phoebe and I had had enough of Paul, our stepfather (even though we called him "Daddy), and his stinginess. He was a decent enough guy, and he seemed loving enough towards our mother, but we knew the guy was very rich, yet he refused to spend much money on anything.
All of our friends were getting cars, and we both wanted one very badly. So we decided that we would need to turn to much more unorthodox methods to coerce him into purchasing our desired vehicles.
We decided to formulate a multi-step plan to achieve this.
First, we began to ramp up our teasing of him. We'd always noticed that he'd admired our looks. He tended to like our "sexy" selfies and pictures on Instagram much more than the innocent, normal pics. We'd even noticed that he had created a fake Instagram account to follow us with. We never said anything or blocked it because we kind of liked teasing him anyway. Also, we had noticed that our panties, stockings and lotions seemed to move around a bit when we weren't around, and it didn't take a genius to guess what he was doing with our missing items.
But now we began posting even sexier pics, and we would dress up and pose around the house taking the photos, usually in the weekday afternoon hours. He stayed extremely attentive to us, always having some ridiculous guise to be around during the photos, but obviously he couldn't act on any of his urges, as our mother would get home around 6:00 each night except when she was traveling for business. We usually didn't tease him much when she was away because we didn't want to risk things getting potentially out of hand.
Next, we paid close attention to his alone time and the time with our mother behind closed doors. He was a fairly easy read on his masturbation habits as he would sometimes lock his office door in the middle of the day; it became more common as we increased our photoshoots.
Another thing we noticed, was that while everyone slept in their bedrooms with the doors closed every night, it became easy to hear when the MBR door was being locked. It wasn't every night, but it was pretty consistent to when we had been teasing or when mom had returned after having been out of town for a few days,
With this research done, we learned that Paul was in the habit of getting off at least every three days or so.
The next step was to determine what type of cars Paul could afford to buy us.
One of Paul's favorite things to do was watch us when we were out back by the pool. We thought it was so cute. He thought he was so sly, but we could always see him watching from his bedroom window. We were confident that this obsession of his could be used to our advantage.
Soon I was reviewing my daddy's finances, which had always been kept as kind of a secret from my sister and me, and we found that he was in even better financial shape than we had previously thought, and we had thought that he was in really good shape already.
While I had distracted our unsuspecting father by lounging out by our pool in my bikini, using tanning lotion all over as he watched from inside the house, Phoebe had snuck into his office and gone through his financial documents. She had learned that he had one cash account with just over a $100,000 balance. Additionally, our house was completely paid for and there was a multitude of stock investments as well.
We decided to start with the value of the cash account. That was plenty of money for him to buy us each a very nice car.
We visited some local car dealerships and eventually met a saleswoman named Suzy. After a few visits we felt like we had met a kindred spirit. We invited her out for a glass or two of wine after work one day, and she agreed.
Over wine, we explained our situation and our plan; at first she was shocked, then skeptical, but eventually she became intrigued and then willing to participate.
Back at home, we found a trip on mom's calendar that would go over a weekend. And as a special bonus, we noticed that her time of the month were the days immediately leading up to the trip. Through careful planning, we were able to make sure that daddy was never alone to take care of himself for the four days leading up to the trip. We did this by planning family activities, during his normal "alone" times, and asking him to help us do chores around the house and such when mom wasn't around. We also turned the teasing down a notch or two so that he wasn't desperate for relief, or at least he didn't realize he was.
On Friday, with mom safely away, the plan could commence.
We headed to the pool to begin our tease. As Phoebe began oiling herself up, I headed back to the house as though headed to the kitchen. But I doubled back up the hallway once inside and acted shocked and horrified that I had "caught" Paul watching us through the window. Even better, I had entered his room just as he had pulled his cock out. I don't think he had even gotten to stroke it once yet.
He jumped up, terrified and embarrassed, while I acted like I was going to cry.
Within moments Phoebe had joined us to see what was going on.
He was too discombobulated to know what to say or how to act, so we sweetly took over.
"It's ok, Daddy," I purred, as I began to softly stroke his neck, "I was just shocked to see this."
Phoebe joined in, "Right, Daddy, we think about you a lot too,"
Now he was thoroughly confused, but we kept it up.
"We can agree not to tell mom about this, ok?" I asked.
"Absolutely," he answered to probably the easiest question he had ever been asked.
I softly kissed him on the cheek as he agreed.
"I have an idea," Phoebe whispered, as she kissed his other cheek, "If you would like to hear it."
"Yes, please," he replied.
I kissed him again as he agreed.
"Well, mom's gone until Sunday," she continued, "Why don't we make these next couple of days our special time?"
"Like, what do you mean?" he asked.
"Oh, I don't know, Paul, just some fun stuff that's just for the three of us?" I answered, "That sounds nice doesn't it?"
As he agreed that it did, he received another kiss.
Phoebe had slipped out of the room and returned extraordinarily quickly, fully dressed. Gone was the swimsuit, replaced with a short skirt, stockings and a silk top.
As this had all been planned, our clothes had been left out in the next room, so as Phoebe returned, I darted out to perform a similar change.
Paul was still in his shorts and polo shirt, and that's just like we wanted him. So we said, "Let's go for a drive, maybe we'll find something to do?"
This time I kissed him first, but then he immediately agreed. I loved this; he was becoming so compliant!.
We made our way to the garage, and we all climbed into the car. Phoebe drove as I sat in the back with Paul.
Instead of my usual tease, this time I remained nuzzled up against him the entire time, whispering into and licking his ears.
"Paulie, you have been so naughty watching us; we might have to find a way to punish you. Would you like us to punish you?"
He seemed confused and didn't know how to respond, but I could feel him get harder and harder.
"Oh, Daddy, that cock of yours is giving you away; you want your little girls to punish you." I teased.
