The owner of the farm asks his farmer boy to grab a pair of boots because he is about to go and work in the dirt, this is what happens after
A farmers boy walks to the 2 (dumb) beautiful daughters off the owner of the farm, and says to them :
(farmer boy) Ur father ordered me to have sex with both of you at the same time.
(2 girls) I don't believe thats true why would our father want that?
(farmer boy screams to the owner) Do i need to grab them 1 at a time or both together?
(owner screams back) both of course.
This was the story of a farmer boy who had his first threesome.
And now for @Jaeger
I know this isn't really a joke but it is a funny story, (probably funnier when ur a bit drunk)
