Been reliving a memory lately of my then girlfriend Olivia's 30th birthday and her special present.

It starts with Olivia tied down on our bed, her mocca legs spread wide. Her favourite toy, buzzing on her clit. A blindfold and headphones blocked out all of her senses.

Olivia, being unable to see or hear, completely at my mercy.

Time to add our three friends waiting in the family room, for us to do as we want to her.

Olivia's birthday begins.

We start with feathers to heighten her senses, ending with tongues torturing Olivia's exposed clit.

One after another, beefy tongues probe and lick her cunt unrelentingly till she shudders with her first orgasm.

Loud shouts of elation echo in the room.

Gregg takes out a red sharpie and grins as he marks her trembling inner thigh.

Now, Jim's turn between her outstretched thighs. His mouth is more brutal, biting her cunt lips. Olivia howls as his thumb enters her ass, matching his tongue licking inside her juiced pussy.

A couple of sexed minutes later, Jim marks her inner thigh.

Olivia panting gives Stan his opening. He slides his nine-inch monster down her throat.

Holding her head, he starts skull fucking my birthday girl.

Moments later, Gregg returns by stuffing his girthy cock deep in her wet cunt.

On the fourth down stroke, Olivia goes rigid, gaining another mark.

I step back in awe as another two loads of cum fill my girl. Then watch the fourth tally mark added. Now wondering how much my sex bunny's tiny holes can take.

The guys return to torture her clit. They suck and bite her clit till it's bruised.

After every orgasm they rip from her, they continue with the sharpie marks on her splayed thighs.

Keeping a running count of how many times she cums.

As the blindfold and the headphones come off, she's so tired and fucking numb. I trace each tally and tell her what a good slut she is. How proud I am of my sex kitten for cumming so many times.

Olivia smiles, looking at me, hearing, "Happy Birthday," from our three rogue friends as they cum on her belly and tits.

I'm proud of being able to fulfill one of my girl's fantasies.
