A little outdoor sex never hurt anyone and for a horny guy who wants to play with his friends mother its the perfect place to make his move. Of course she might play a little hard to get but then she hasnt had a hard cock in her pussy for quite some time so shes not going to hold out for too long. And once she gives in shes going to want to fuck her brains out right there in the garden. I guess some guys just manage to make their own luck just like Johnny did this time.
