Lots of family men out there are indeed lusting after the babysitter or the nanny. It’s only natural. You have a woman usually a good deal younger than your wife, likely in better shape than your wife since she never had kids, and you see her around your house a lot. Maybe if it’s a nanny, she even lives under your roof and you have access to her panties to sniff, or her toys to lick after she’s done using them.
The wife is likely too tired or doesn’t even care about sex anymore and isn’t paying the attention she should, little does she know the naughty thoughts you have been harboring for the nubile, sexy young girl that’s always within arms reach. Perhaps you masturbate about her as you watch porn since wifey hasn’t the desire to satisfy your cock anymore. A few male celebrities in recent years have been busted publicly for having affairs and even out of wedlock children with the nannies that are or rather were, right under their wife’s nose right in the same house. The wife might not be giving hubby any anymore, but boy she feels pissed off and betrayed when this comes to light! (She’d rather you lead a sexless life like she does.)
The babysitters and nannies out there are often bored with boys their own age and look to the more experienced men around her, and often it’s the daddy of her charges that she will turn her attentions towards. If the man by chance also drives her home, well, then there’s some time on the sly away from wifey for a quickie in the car…
