It was an uneventful Tuesday and I was being lazy, laying around in bed until almost noon. My dad had awakened me just before 5:30 AM and I was so tired at the time that I could barely remember him fucking me before he left for work. One thing I knew, it wasn’t a dream - the evidence was encrusted on my pussy and sheets. Unfortunately, I was still recovering from the weekend and trying to be responsive at that early of an hour was just too much to ask. From the evidence left behind, obviously my dad didn’t mind fucking me while I was all but asleep and unresponsive! In any case, I drifted back off to sleep immediately after he left and now it was almost mid-day and I still hadn’t even gotten out of bed yet!

I was finally awakened once and for all when my cell phone rang. I wasn’t going to answer it until I saw it was my cousin Tammy calling. She was excited about something and was calling to ask if she and Rick could come over to my house for a while since she knew I was home alone. Evidently my mom must’ve told her mom who told Tammy. Anyway, she was going to tell her mom that they were going to go to the mall for a while but she hinted at other plans they would tell me about when they got to my house. Naturally I was curious so I told her it was fine with me. When I hung up I finally rolled out of bed to get cleaned up before they arrived. While I was in the shower I made sure to make an extra effort when I shaved my pussy and legs as something told me they weren’t coming over to watch TV.

After the shower I debated quite a bit over what to wear and decided the less and looser the better. My old pair of gym shorts were so baggy that when I sat down in them or laid down on my stomach they allowed a pretty good view up the legs and then you know where further up. A tube top is always a good choice when you want to make sure someone has easy access to your boobs so I slipped on a small rainbow-striped one, arranging it so it barely covered my boobs. After all, it wasn’t like either of these two hadn’t seen me naked before so what was there to hide! I pulled my hair back in a ponytail so it would be out of the way. No need for socks or shoes since we wouldn’t be leaving the house. I splashed a little Charlie on my neck and pussy (what I can I say, my mom got me hooked on it). A quick final check in the mirror and I headed downstairs to wait for them. In the end I decided to hang out on the deck so I could hear when their car pull in and not be surprised.

Heading downstairs, I grabbed a glass of water as I passed through the kitchen and then opened the door at the rear of the kitchen leading to our deck. Since our house was on a typical Pittsburgh hill, the garage was at the rear of the house and actually level with the basement thanks to the steep slope. Our deck essentially formed a roof over the garage so it was quite large - the same area as our two-car garage. We kept some outdoor furniture out most of the time and today the chaise lounge beckoned me so I fell back into it and closed my eyes to keep out the sun. It wasn’t the clearest of warmest of summer days but even with a little cloud cover the sun was still bright enough to make me wish I’d brought out my sunglasses. Fortunately it was still plenty warm out, even if you couldn’t hardly see any shadows, enough to warm the cushion on the lounge chair so when I laid back on it I could feel the heat against my back and legs.

From where I was I could see the top of our driveway and still no sign of Tammy and Rick. Well, where were they? I started to think of all the possible reasons for their visit. Who knows, maybe it WAS just to watch TV although that would’ve totally blown me away. Maybe for some reason she wanted to blow him (I think sometimes she wanted to do it even more than he did!) but with her mom and sister home they just couldn’t find the right opportunity and now she was too horny to wait any longer. Of course, it could’ve been the same for Rick as well.

My REAL hope was that at least one of them wanted to take advantage of Tammy’s new “classification”. She was no longer a virgin and at her age that meant she was at the crossroads. This was the time when she needed to decide whether she was to become a real slut or just be a girl who had sex early and then quit for a while until she got older. Somehow I couldn’t see Tammy doing the latter which meant at least one of them was thinking naughty thoughts. Most likely - both!

I remembered back to the previous weekend and how wet and horny I was when I got to watch my dad fuck my cousin for the very first time. In a way, it was a first for both of them. It was her first time to have sex while it was his first time to fuck a girl her age - at least not since he was a teenager himself. What forty year-old guy doesn’t dream of fucking a little fourteen year-old - whether he admits or not?

Almost just as hot was seeing her dad fuck her for the first time the very next day. Tammy was extremely petite and had just turned fourteen in June. Being only 4’6” tall, maybe seventy pounds soaking wet, and tiny boobs that were just starting to develop, she looked more like a twelve year-old. I knew how it felt to look younger than your age, it seemed to be a curse in our family although the guys seem to love it.

The more I thought about watching her being fucked, the more my pussy ached and finally I had to do something about it or go nuts so I slipped my hand under the elastic waist of my shorts and started to masturbate. The shorts quickly became a nuisance and since nobody could see me up on our deck anyway, I pulled my shorts down to my ankles and spread my knees wide apart to make it easier for myself. As I rubbed my pussy I dreamed about how I had watched my dad’s cock as it forced its way into Tammy’s tight virgin pussy that first time, bending and straining as her tight little cunt resisted valiantly but finally winning the battle and slowly sliding into her as she groaned. Then my thoughts turned to her dad as he entered her for the first time. It was almost like she lost her virginity twice that weekend - physically to my dad and then incestuously to her father.

My pussy was getting so wet, just like it had while my dad and uncle had fucked me over and over throughout the weekend. Without really thinking about it, I slipped my tube top down to free my boobs after which I started to play with my nipples with one hand while I used the other to play with my clit. My eyes were shut tight and I was getting so close to my orgasm when suddenly I heard a noise from the house and the door to the deck burst open. I hadn’t realized how much I had shut off the rest of the world while I was masturbating but thankfully Tammy and then Rick appeared.

“Damn girl, couldn’t you wait a few more minutes?” Rick teased me.

I just glared at him and pulled my hand from my pussy.

“Whoa! I didn’t mean you had to stop,” he chortled.

From the smug expression on his face I could tell he was dead serious. Typical horny teenage boy - just thinking about himself. He didn’t care if I got off so much as he just wanted to watch me get there. Normally I would’ve treated him to his little fantasy and finished myself off while he watched but Tammy was here and I couldn’t wait to talk to her. For some reason, habit I guess, I pulled up my tube top, grabbed my shorts and quickly slipped them on. Soon the three of us were sitting around the glass-topped table on the deck. Rick cranked opened the umbrella even though the sun wasn’t all that bright.

“So, what brings the two of you over?” I asked, acting as if I had no idea.
