I went to my grandfather's house last week with my by bus.We had to stand as we didn't find any seat.Suddenly i felt someone feeling my boobs and i looked behind to see.It was my own dad!He smiled at me and put his hands under my shirt and pushed my bra up.He squeezed my boobs and pinched my nipples.I was enjoing and getting wet.As the bus was over crowded,none noticed us.My dad's hand then moved under my skirt pulling my panties down.He felt my wet pussy and fingered me.Then he put out his long cock and i began to stroke it with hands.After that he took his cock and insested it directly into my pussy.I let out a light scream but nobody noticed.He fucked me and whispered to me,"I'm cumming."After that i felt my pussy filled with my dad's cum.As i was on pills,i wasn't worried of pregnancy.Moreover,it was the best journey in my life.
