Recently, my wife and I got our hands on a Vac-U-Lok harness - and love it.

The only problem is that the cock it came with wasn't very exciting... We like the realistic looking ones, so this 'dong royal' looked perfect. We ordered it in black - more because it went with the harness than anything else (although that's not what my wife says.)

The cock itself arrived in a shoe-box sized box and was wrapped in plastic packing. At a heft eight inches long, it was big, black and beautiful and had that satisfying, meaty heft to it.

The cock's incredibly realistic, right down to the network of veins and big, wrinkled balls at one end. It's also big - my wife could hardly fit the swollen tip into her mouth! Overall, we were incredibly satisfied by the look and feel of it, although it did smell a big plasticky and there was a tiny tear where the scrotum met the shaft. It didn't look like it was getting any bigger, though, and I think it was a molding tic rather than any weakness in the cock itself.

The cock snapped into place perfectly on the Vac-U-Lock harness and hung in a good position, ready for action. It looked excellent - I always get hard when my wife 'straps it on' and this cock looked wonderful on her.

I don’t consider myself gay in the slightest, but my wife is constantly teasing me about how much I like anal play and how turned on I am by the sight of her in a strap-on. She thought it was quite Freudian that I’d picked a big, black cock for her harness and got quite bullish and arrogant when she’d strapped it on (which was pretty sexy in and of itself!)

Because it's made out of cyberskin, it's important to use a condom on it to keep it hygienic and also to protect yourself from BPA. We only keep Trojans in the house (I'm, ahem, not too small) and they fit perfectly.

My wife and I switch between being the submissive/dominant one - and today, she was definitely the boss. My wife wore her knee-high black boots and the black strap-on harness. I was all too eager to follow her commands as she ordered me to strip.

She ordered me into the kitchen on my hands and knees – crawling across the cold tiles. Then, as I shivered, she barked at me to get on my knees and eagerly stepped in front of me.

I felt incredibly vulnerable and submissive, cold and naked while my wife towered over me in her boots. She grabbed a fistful of my hair and thrust my head between her legs.

The dildo’s HUGE, so I could barely fit the tip into my mouth. She didn’t care, though – she even slapped my cheek as she ordered me to ‘suck her.’

After I’d choked and gasped for breath, saliva drooling down my chin, she wrenched the glistening cock from my mouth and ordered me onto my hands and knees. As I turned around, she pressed the heel of one black boot into the small of my back and forced my shoulders down, until my cheek was pressed against the cold tiles and my ass was sticking up into the air.

I saw my wife’s shadow fall across my back – she was standing over me, pulling a rubber condom onto her big, black cock and slathering it with lube. Then, with a squirt, she spurted lube between my buttocks and roughly slid her fingers between my cheeks, getting me good and slick. Her fingers were so wet that she had no problem forcing first one and then two fingers into my ass – making me groan with discomfort and need.

Pressing one hand into the small of my back, she pressed the head of her cock between my buttocks and I felt my cheeks forced apart…

The cock was so big and my ass was so tight. Despite fingering me, my butt still refused to yield until she spurted more lube between my cheeks and jerked her hips forward. Finally, reluctantly, my clenched little hole surrendered and I groaned as I felt myself split in half…

It was BIG. The feeling was SO intense and overwhelming. I begged her to slather the shaft with more lube as I thought she was tearing me apart with her hard, merciless thrusts…

After she added a little more lube (actually, a lot more) things shifted. The pain turned to discomfort – and then just intensity. Her fingers gripped my tight, muscular ass cheeks as she spread me wider. Soon I was taking her shaft all the way to her fake balls – and my prostate was humming from the attention.

Soon, I was burning with need – thrusting my hips back against hers and meeting each thrust. I felt my balls tingling and used one hand to jerk myself off as she fucked me… In seconds, I was spurting come onto the kitchen floor, my ass clenching.

When my wife finally stopped thrusting, she pulled the cock from my ass and I felt like she’d pulled my insides out with it! But as I lay on the cold tiles, I felt deliciously satisfied – a very well-fucked husband.
