New Boyfriend

I have been divorced for a year, I moved my boyfriend in that's when the trouble started from my daughter, she was very upset when her dad moved out, she was very hostile from day one
the atmosphere in the house was bad, she objected to him walking around in his under pants
saying it wasn't decent, she never objected to her dad in the nude at times with a hard on, she was always dads girl, is did thing something was going on between them but i thought don't be disgusting he wouldn't have sex with hi own daughter, part of my employment is working away at times for up to a month, i was dreading it, leaving them together, when i returned i thought world war was three would have broken out, but no everything was calm, they seemed to best of pals, i noticed she was all smiles and happy and wasn't wearing a bra, when i went up to unpack i could see the double bed had been slept in by two people,, when i quizzed him about it he said he had slept on different sides, when we had sex it wasn't the same, on the first night home we usually had sex three times, but only once and it took him longer, ime sure he is fucking my daughter, if it keeps things running smoothly i don't mind when we have sex, i think of his cock in my daughter.
