Daughter saw me jerk to her

Recently when me any my daughter were home together, she was wearing tank top and shorts, her figure was insanely clear to see, tight and slender... her shorts wrapped around her perky ass and i am ashamed to say so but seeing her got me aroused, while she wasn't looking and facing away from me, i started rubbing myself over the pants, eventually taking my cock out and stroking it to her, she turned around suddenly and noticed what i was doing... surprisingly she didnt say anything and looked, gave a slight confused nod and just went back to what she was doing. I have no idea why but that made me so much more aroused and i finished soon after...
