It was the last day of my summer holiday staying with my dad and the sun was shining through the gap in the curtains as I slowly awoke and stretched lazily. I got out of bed, showered and went to get dressed. I pulled on a white lace thong and matching 34C bra smoothing my hands over my toned body as I looked in the mirror. I chose a strappy pale yellow short summer dress that contrasted nicely with my soft tanned skin and let my golden sun kissed hair flow loose and wavy down my back. I slicked on some black mascara and swept a dab of blusher over my cheekbones before making my way downstairs to the kitchen for breakfast.
My dad was already up, eating toast and reading the paper at the breakfast bar. He was wearing a plain white t-shirt and his favourite blue shorts which made me cringe a little. They're shorter than what's in fashion at the moment but he likes them and wears them anyway. He's in good shape for a 46 year old so I guess he can pull it off. I said good morning to him and helped myself to coffee and popped some toast in the toaster. We talked about what we'd do that day and eventually agreed to go down to the lake, rent a boat and spend the day relaxing and making the most of the hot weather. Unfortunately his car had broken down the day before and his mate Richard who was once a mechanic was due to come round tomorrow evening to take a look at it for him. I didn't bring my car with me since it would have been a six hour drive so I got the train down for the week instead, which meant we didn't have our own transport and would have to get the 162 bus to the lake.
After breakfast we packed a bag of food and drinks and set off for the bus which takes just under an hour to get to the lake. We didn't have to wait long until the bus arrived but it was packed and really hot with it being a Saturday and such gorgeous weather. My dad managed to get a seat near the back right by the rear door. I tried to follow so I could stand near him but there were so many people it was difficult to get through. With more people getting on and off the bus I was moved back and forward with the crowd and by the time the bus started moving again I'd ended up stood right in front of my dad but with my back to him. I tried to turn around but there were too many people crushing against me so I had to stay where I was and we set off for the lake.
The bus stopped at some traffic lights and as it accelerated again I tried to move my foot to get better balance only to find there was nowhere to move it amidst all the other feet and people's bags. I overbalanced and started falling backwards and felt my dad's strong hands grab my waist as I fell. I ended up sitting on his lap facing forwards away from him. I felt really awkward as we don't have a touchy sort of relationship so sitting on his lap isn't something I'd usually do. I tried to get up but there were so many people and I had no leverage, I heard my dad from behind me telling me it was okay; I could just stay where I was. We sat for 10 minutes or so, me still feeling slightly awkward about it. As we rounded a bend the lady in front of me moved position again and stood on my foot by accident. She looked over her shoulder and apologised but I just said it was fine and scooted further back on my dad's lap, I felt him tense up and thought he must be feeling awkward like I was.
As the bus swayed on I suddenly felt something brush the underside of my thigh close to my lace covered pussy, I thought I was imagining things at first but then I felt it again. To my horror I realised that the only thing it could be was my dad's cock. I must have accidently rubbed on him when I moved back causing his cock to stir. I stayed as still as possibly my face flushing with embarrassment. Why was this happening, I was his daughter, surely he couldn't be getting turned on!
As the bus continued, with each bump and turn of a corner the rubbing pressure on the underside of my thigh increased and I could feel my dad trying to move backwards into the seat. I didn't know what to do so I remained as still as possible and pretended I hadn't noticed anything was wrong but I was alarmingly aware of the fact that my short dress wasn't covering my pussy underneath me as it had rode up a little when I sat down. There was only the sheer lace fabric of my thong and the thin material of my dad's shorts between me and his hard cock which was still rubbing an inch to the left of my pussy lips every time the bus moved.
Suddenly the bus lurched to one side as it took a corner and I was jolted to the left on my dad's lap. With the sudden movement my body was ground down causing his hard cock head to push sideways on my thong, pushing it to the right of my pussy lips. I felt panic rising as my pussy was now completely exposed and the head of my dad's cock was pushing horizontally between my pussy lips, only separated from me by the thin material of his shorts. I gasped, it felt so big, my boyfriend's cock is 6 inches and not very thick but my dad's felt as thick as my arm and it was at least 8 inches long. I'd only just turned 18 last month and lost my virginity to my boyfriend shortly after. I felt so ashamed as I felt my pussy lips swell and my tight hole become moist. How could this be happening? My pussy became really sensitive and I could feel every twitch and slip of his hard cock as the bus continued on.
