Wife's big cock experience!

This is a True story! Wife wanted to write about.

I (39m) & her (35f) after 2 kids 11 & 7. My wife confesses one night that she wants to fuck & feel what another bare cock feels like. She requested it had to be bigger than mine (me 8ins) & uncut.
After couple of months of talking she mentions .. "try just once".
We had practiced safe sex for 18 yrs of our married life. 12 days oral (foreplay including bj swallow & me eating her pussy & fucks) & fucks another 12 days of only oral to avoid unwanted pregnancy. No anal.
Me: 6'2", slim, 8ins uncut.
Wife: 5' 10", big framed, with curves, 44+breast - 36+ waist - 46+ hip/ butt, large swollen pussy mound, protruding libia approx 2inches after 2 births, unshaven.

She wanted to experience oral sucking new big long cock, & fucking her pussy bare & cum fill her. She needed to be with him & be taken by him as often & have fucking sessions to last over a long weekend (Fri..Mon) just drink, eat & fuck. She wanted to experience having her pussy fucked full of cum & dripping cum between fucks for the three full days.
After reluctantly agreeing to her requests, I asked her that she should make herself better presentable to her prospective fuck partner. She should shave or wax her ebony pussy and thighs. She agreed to a smooth .. clean pussy. I bought her an electric shaver.
She never wore trackpants as it very obviously showed her prominent & protuding pussy mound.

A single mom with 3 kids has been a good friend of ours. We had 3somes with her occasionally when she could get her sister to babysit her kids for the weekends. She agreed to wax my wife's pussy area & my wife did hers.

I requested wife to have an Injection, or an IUD inserted to be safe from unwanted pregnancy because she did not want condoms. I suggested that to find a sex partner may take a while.

We has a 3 yr old rottweiler (docked tail) as a big guard dog to ward off car thieves & drug peddlers in surrounding areas.
We had a special cage room built in our double garage. He roamed our fenced property We would let him in our wooden floor home in weekend's when our kids would pack their bags & go to their grandma's. I noticed that often the dog would nose my wife between her thighs when he was inside our home. I hinted to my wife that he likes wife's pussy odour and would love to lick her pussy if she let him.t
Wife would brush him aside in a playful manner & tell him to go sit. He listened to her & go sit at her feet.
I had on occasions seen him licking his fully erect cock but on this occasion I jokingly mentioned it out to my wife that I have found her fuck partner with a huge cock ( bigger than mine 8ins.
Wife looked my way in a surprise with amusing look on her face and said "REALLY!!!".
I said yes!. She was excited and said she is feeling her pussy moistening.
I asked if she really would like to fuck bare with no condoms the 10 inches if she had the chance.
Wife paused a sec and coyly said "yes" biting her lower lips.
I told my wife to do as I say.
I blind folded her while she was laying in her recliner lazyboy.
I said to give me 5 minutes before I take her blind fold off.
I rubbed & squeezed the rottweiler 's cock till it was fully out oh his sheath and long & large at almost 9 - 10 inches without the knott.
The knott would add approx another 1.5 to 2 ins when it appears.
Wife asked when I will take her blindfold off?
I asked "why"?
Wife says her pussy is getting very wet in anticipation of my surprise big cock I had mentioned.
I got 2 pairs of baby Soxs put on the dog paws. I got the dog to hop on & stand up on an oval coffee table with wheels.
I brought & pushed the coffee table near wife's feet. The dog's dick will be within 12 inches to wife's face after she uprights her lazyboy chair & I take off her mask.
I still held the dogs massive cock within the palm of my hand and it was just 3ins from touching the coffee table top.
Wife sat upright. I swiveled the coffee table and I moved & pushed the dog cock between his legs & pointed horizontally out his back within 12 inches of my wife's face.
I said " Ready!" & I took off her mask band.
Wife opened her mouth & remained open for 30 seconds couldn't say anything.

I held wife's hand & guided her to hold her lover / partner's big red pink cock that has moistened her pussy.

I told her that this was her safest fuck partner who will never get her pregnant despite filling her vaginal - pussy & maybe uterus with 50ml for each fuck.
I told her to kiss the dog cock. She kissed & licked the pre cum off & smiled ...
I told her that when the dog fucks
& locks his cock in your pussy the knott will be larger than a tennis ball size. The dog will knott you from 15 mins to 40 mins (depending how tight your - his bitches pussy is) while he deposits his cum in your - his bitch vigina / uterus with him hoping to impregnate you with as many puppies.
