I was glad because I didn’t admit it but my pussy was a little tender. We cuddled and then fell asleep.So it was that for the rest of the week we ex...erimented with sex in every position possible. I was in heaven. One night I said to dad “how come mum said you were dull and boring. You are anything but”. He just laughed “it was because she would only want sex in the missionary position, wouldn’t suck my cock and didn’t seem keen on anything kinky”. I realised SHE was the problem and not dad. Not. She had my shorts off easily and resting on my knees in an instant. My cock throbbed as I felt moments away from feeling her mouth do great things. She rolled her near naked body over to lay on her stomach and place that luscious mouth where I wanted it. But before she took it in, she reached over, grabbed the dildo and lube and placed it next to my ass. She slowly started licking my shaft, using one hand to stroke me. The other was doing curious things with the lube. She, with one hand,. Thin waist and a gorgeous, thick V of light brown/dark blond curls that thinned out and split when it reached the beginning of her slit. I couldn’t say a word, I think my tongue was as hard as my dick, and Mother laughed happily. “I’d say the condition of your dong answers my question. Jesus, Paul, I think your prick’s bigger than your father’s was.” Looking at Mother naked was arousing enough, but her talking about the size of her tits and comparing my prick size to Father’s was way over the. Kathy was always a people pleaser, doing her best to make sure those around her were happy with her. However, she was still very shy during sex, preferring to keep the lights off and the sexual acts mostly vanilla. One point of frustration was her inability to orgasm, which I tried in vain to fix but only got told she still enjoyed sex even if she didn't come.While I truly found Kathy sexually attractive, her shyness and modesty during sex slowly led to me developing an increasing interest in.
