Mum and Dad have a 13 year old daughter ,and mum thinks its time dad tells her about sex

so dad takes her into the living room and sits her down and tell her about the birds and the bees

 when he was finished he asked if there was any questions, Yes she wanted to know what a penis was,

so being a liberated male  he unzips his pant and pulls his penis put and tells her that was what one looked like.

She replied it looks like a C..k but only smaller
