A new dog on the block

I have a new niegbor,his gay and has a bull mastiff, this dog is big, his sheath looks to be about 16"long,I can't imagine what it's length is hard, but I'm going to find out, I want all of it deep inside me.
The guy's name is Ronnie, the dog's name is Pete, I work out of a big shop behind my house.
Ronnie likes to sunbath in the back yard, I make sure my dick is hanging out of my shorts for him.
His started leaving his dick out too.
It's time to step it up a bit. I start stroking it for him, my peared 8"dick gets his attention when it's hard.
His is smaller about 6",he comes to the fence and asked if he can come over, I say yes as long as you bring Pete with you.
He agrees, he and Pete are in my shop, I'm hard and Ronnie is all over it.
Ronnie is on his knees with all of my dick in his mouth,Pete tries to mount him, I ask does he fuck you?
He says his to big for me, but I give him blowjobs all the time.
He knows I have a great dane, I tell him I let Brutus fuck me all the time.
Pete is a giant compared to Brutus,his dick looks to be about 15"-16" in length soft.
He asked do you want him to fuck you, oh hell yes I do.
I already got a padded matt on the floor ready for me and Ronnie to fuck.
I get down on my hands and knees, Ronnie guides Pete to my ass, he licks my rose bud, his slobber lubes it good, his big tongue goes into my hole,it deep inside me.
Pete mounts me, I can't hold his weight, I get the padded bench I use with Brutus, he mounts me again,his dick is stabbing at my hole.
It hits it's mark, it opens me up,it's as big around as my wrist and it just starting to get hard,he rams it into me, it takes my breath away,I feel fate,he starts pounding into me, his knot is trying to go in, Ronnie ask if I want him to stop it from going into me, no I want all of it deep inside me.
Pete presses hard against me,I'm opening, my hole is stretched open wider than ever.
It pops into me. Things go black for a second. I come back and I feel the tip is above my belly button, the knot is wedged to the inside of my hip bone, it's starting to get bigger, I feel so full,I rub the tip where it's bulging out against my belly, his still pounding into me, his pace slows, his getting bigger inside me,I feel like I'm going to split open.
Then I feel it starting to pulse and that hot liquid starts squirting deep inside me,I remember Ronnie is there, I tell him to suck on my dick cause I know I'm ready to come,he takes all of me,I feel the head going into his throat,it starts squirting out,It squirts more times than usual,he gags,that makes me come more, I've comed more than I've ever before. Pete is still locked inside me, my insides are bulging out,his still coming in me,I'm sooo full, I don't think I can take anymore,he starts getting smaller, I pull off his dick,his come pours out of me,Ronnie is still under me,his covered in dog come,he rams his fist into me,I start coming again with out any come coming out of me.
I colaspe on top of him, I can't move, I roll off the top of him,I lay there totally exhausted.
Ronnie says I'm going to let him fuck me next,his never been fucked like that before.
I said well you better let Brutus fuck you first, his smaller than Pete,Brutus fucked him good.
Ronnie said that was intense,I'm ready for Pete, I said no your not,Pete is at my limits, you've got along ways till your ready for Pete.
Pete does eventually fuck Ronnie.
That's another story.
