Daddy's Knee

Being such an active and horny girl growing up, getting caught was pretty much aninevitability. A when, not if.  It didn't help that I would sometimes deliberately masturbate with the chance of gettingcaught, such as with the door open or in the living room after school when Iknew I had maybe half an hour before my sister or one of my parents got home. Iwould play and edge, and then when I heard the door downstairs open I would gofor it, not knowing they would be going into the kitchen first or comingstraight upstairs, so I would time my orgasm to the last possible moment Ithought I could get away with. Any they were amazing! That vulnerable, exposedfeeling and the risk of being caught would just set me off like nothing else.

I was never caught outright, though I had more than a few close calls and odd looks!

It's not like they didn't know I masturbated. My mum has caught me a whole bunch oftimes with my hands down my jammies or humping a pillow in my room. She alwayshad the worst timing and a habit of not knocking. Looking back now I'mpretty sure she knew exactly what I was up to in my room before waiting for just right right moment to walk in;she just got a thrill out of busting and embarrassing me!

My dad was much better with knocking, being the only male in a house full of girls, buthe knew what me and my sister would get up to when no one was looking. 

One time I was sitting on dad's leg as we were doing something on the computer. Iwas doing an assignment for school and he was teaching me how to format andmake it look neat and formal, since I wasn't in primary (middle) schoolanymore. 

I wasn't particularly horny at the time, but sitting straddling Dad's leg was rather "pleasant" in an unintended kind of way. I wasn’t really paying it much attention or doing anything about it. After a while, however, I could feel mylips starting to tingle and my clit begin perk up under my tights. Only mildlyawkward... I remember thinking how glad I wasn't a boy or it would be totally obvious!

I tried to put it out of my mind and concentrate on the First Fleet, but every smallmovement of his leg and shift in my body as we leant from keyboard to book andback were sending strong signals form my pussy and clit straight to my brain and right back down again. 

Despite my best efforts my focus vanished and my brain scattered and I wasstruggling just to maintain a straight face and level voice as I kept up theconversation with Dad as we worked on tweaking paragraphs and margins andmoving pictures around. The angle of his leg meant I was sliding forwardslightly, pulling the soft seam of my tights harder against my clit.

Severaldistracting minutes later and I started to feel that initial shimmer of a budding orgasm deep inside me and I knew I was in trouble!

I froze, concentrating on holding as still as I could, trying to keep my breathing and voice leveland focussing on holding back that rising pressure. In frazzled my state, Igripped my thighs tighter around my dad’s leg to try and hold myself still,but that completely backfired as I felt the building pleasure between my legs intensifysharply and I gasped involuntarily and held my breath and hold back theimpending orgasm, but my orgasm began to gather momentum and build up, and Iwasn't even moving, just my weight on my vag and my tights pulled taught over my clit. 

I began to panic and in that stateI thought if I simply got up it would be totally obvious to my dad what was goingon, so I held still and tried to hold it back, butit continued to build and build and but after a minute or two the inevitable happened andI just came, with a gasp and a squeak and a shuddering grunt, my body then just taking over and grinding my clit against my dad's leg for three or four spasms before settling.

It was one of those orgasms that felt like it would burst out of my stomach. Trying tohold it back only allowed it build up to a whole other level. I satthere motionless, trying to ignore the last of the little spasms and twitchesof pleasure as they ebbed away, super conscious that I had just had an orgasm on mydad’s knee! I could only sit there staring at the screen, pretending nothinghad happened and it was a very awkward silence for some time before either ofus could speak again.

Did he not notice? Surely… he never said anything or let on (nor to this day) but he can'tnot have.

I didn't want to get off him and leave because that would have just confirmed my guilt,so I just sat there straddling his leg, still getting little twitches andshudders on the inside, prolonging and drawing out my orgasm. I was convinced if I gotup there would be a damp spot so I just sat there pretending I cared whoCaptain Cook was as we awkwardly carried on for a few more minutes.

In the end, I had to get up because I could feel another orgasm starting to build up again as my accidental oragsm was still fading away! So I stood up quickly, mumbling something about needing to pee and went and hidin my room for the rest of the evening until Mum came up and got me for dinner.
