Cant say I understand fully, since my last dog passed away a few years ago, and his favorite spot was at the foot of the stairs or out in the yard on nice nights.
But I can relate to being cockblocked, but by my children.
A funny story.
This was when my second daughter was four.
One night me and my wife were getting it on with a friend, who was the babysitter, a girl from the class my wife attended college with. The time was right, it was after my third daughter was born, and my wife had fully recovered from the pregnancy.
So we were all over each other. The baby was zonked, so we thought we had time to get some long awaited fucking in. My wife was having the time of her life as her friend was eating her out like a buffet, and I was helping, as I was plowing her from behind, spanking her ass.
A little voice was crying out at the baby gate we installed, the one that opens like a door from one side, but cant be opened by a child from the other.
"DADDY, DON'T SPANK HER, SHE A GOOD LADY!! DADDY NO HURT HER!!!"
my cute as a button four year old was pleading a case for me to stop spanking the babysitter, with my cock buried deep in her. The speed we all covered up, and got proper was immeasurable.
That night I could not regain my erection, and we settled for light foreplay before going to sleep.
The talk the next morning was priceless.
