Part 1: Beginnings
 
A little backstory:
 
Samantha Collins (or Sam for short) was a 5'8" 32 year old woman with large DD breasts, pale skin, long black hair and bright blue eyes. She Was the owner of a law firm that she inherited from her father who passed away 3 years ago.
 
She has a large English mastiff named Max whom she has had an "interesting" relationship with for the past year. You see for the 5 years she's had him he's always been extremely horny and would fuck everything he could. From stuffed animals Samantha had to every neighborhood dog around where she lived max would fuck everything he could.
 
Max Also Had another problem. He had a monstrous appetite. He would eat large bowls of kibble in one bit and she would constantly have to refill it. Luckily due to her job she was able to afford food for him quite easily.
 
They lived alone together since Sam never had any interest in being in a relationship. Due to this She was also a virgin. At least until one night when Max decided he wanted her...

Max walks into the room while Sam is on her bed naked about to go to sleep.
 
"Hey boy! Ready for bed?" Sam asked. Max responded by jumping onto the bed with his tail wagging.
 
Sam Patted the spot next to her and said "Alright lay down and go to sleep." But max didn't wan to go to sleep. He had another idea.
 
Without warning Max started to Shove his head at the pillows. Moving them around.
 
"Max stop/ I said bed not play." Sam said while giggling.
 
Max went to the foot of the bed and stayed there while Sam started to Put the Pillows Back.
 
Without realizing it Sam was now on all fours with her ass Facing Max.
 
Max Wasted no time and immediately jumped on Sam's Back.
 
Sam freaked out "What are y--" But before she could finish her sentence Max Thrusted His large dick into her. Breaking her hymen and causing her to wince in pain.
 
However the pain didn't last long as Max was furiously Thrusting into her and it started to make Sam feel good.
 
After about 5 minutes of Max fucking her she had an orgasm.
 
as soon as she did Max's knot expanded as and he pumped her womb full of his cum.
 
She spent the next hour laying there tied to Max who was still on her back.
 
Max was finally able to pull his dick free which released a flood of his cum.
 
Sam was laying there in the aftermath. Realizing she just lost her virginity to her dog and liked it.
 
She then passed out and when she awoke the next morning max was laying beside her.
 
"Good morning Max!" She said right before kissing him on the cheek.
 
Max then got up and started sniffing her pussy before giving it a few licks.
 
"Oooh yes!. I guess you want to go again boy?." Sam says while getting on all fours again.
 
"From now on you can have me whenever you want." Sam says in a seductive voice.
 
And so began their relationship. Max would fuck he every night before bed and every morning before work. And Sam never wanted it to end.
