Pam returned from a hot day in class. As she stripped off she was unaware of her dogs unatural interest in her! In just a couple of years her puppyTexas had grown some and not leased in the doggy-cock department! but there’s more...

It was high summer and the house was quite as Pam returned from a hot day in class and she dumped her homework on the sofa and ran a hand over her flaxen hair, which after walking home, felt lanky.

She went strait to the kitchen tap, and gulped down a cup of cold water; and she felt it tasted like liquied silver. She didn’t normally drink water; and the next unusual thing she decided to do was to have a cool shower right now!

As she stripped off in her bedroom, Texas came in and padded up to her. He rose up and began licking her face. His collar tags jingled in her ears and her hands spread innocently over his warm ribcage to run down his sides.

But she was unaware of his unnatural interest in her; that her odour had made Texas unusually frisky. His damp nose mussed her earlobe; his chest brushed against her bare nipples. She drew in breath at this new sensation and giggled nervously; suddenly wanting to feel his thingy which had so attracted her lately; and her hand now so close to touching!

Her heart thumped upon feeling the warm sheath between his hindquarter, and her fingers ran over the silky sheath and then the firmer ‘bone’ inside! She’d held her breath as her her hand outlined its heated contour and then for a brief moment ... she firmly held it!

Tex grunted and plopped down from her onto the floor; then lifting one hind leg he began licking his thingy where she’d aroused him!

His tongue slurped over that red tip that now peeked out its sheath. With each slurp his black bollocks swung between his pink flanks. It so mesmerised her. She had never done anything like this before!

She also felt guilty and embarrassed; recalling that the little brown Boxer puppy with a stumpy tail had been for her 12th birthday; three years ago ... then her hair had been long ... but now it was bobbed shorter and she wore a 32” bra to support her budding breasts.

She had grown some; and so had Tex, he was full-grown; especislly between his legs.

Recently, on occasions at home, her mother was distainefull at what she called, “that rude habit Texas has develloped.” Yet her father jovially called it a natural animal instinct; and that had pleased Pam, because Tex wasn’t rude; he was lovely.

Tex’s thingy had played on Pam’s mind of late and this moment was hergolden chance. There was no one at home; just the two of them in the bedroom; what had she to loose?

Pam shifted herself alongside Tex; her hand cautiously stroking his tummy hair and then lower onto the pink-soft skin between his flanks.

Gradually she got her hand closer to where he was licking. Tex paused to look at her and seemed to be waiting for something.

Pam was so very nervous but she had often thought about doing this. Gingerly she stroked the leathery jacket-like sheath and rolled the slippery wedge in her fingers. Her tummy throbbed with excitement. She glanced at him. Tex just blinked at her and panted quietly.

Pam smiled in return. Now her fingers parted his sheath to reveal more of the shaft. Her eyes widened in disbellief as his cock slid lazily out, glistening like a jewel! Pam felt her face flush hot! Exposed it was much thicker than she’d imagined and even now, expanding!

Pam’s hand slipped into her pants to finger her clit; and then whispered,” That sure looks finger licking good Tex.”

It was just the signal Texas had wanted and his wet nose went between her legs. Her thighs parted subconsciously, allowing him to mussel inside. Her head began to spin. A primeval cry rose up from her throat as a bolt of pleasure tore through her. It was Pam’s first orgasm.

Her ecstatic reaction startled Tex. His head cocked aside at her.

Gingerly her sweaty hand closed around the cock. She looked into his eyes and Texas blinked. Instinctively Pam’s hand began to pump on the shaft. The gland throbbed, still expanding. Pam felt tugging and squeezing below her tummy again. So cool thought Pam; better than a soppy boy too. School-friends bragged and bluffed about their boysfriends cocks. But she’d felt embarrassed not knowing about it. Now she had something with Texas; and they would never know how big he was.

Then a strange thrill grew as Pam suddenly imagined what she could do with Texas. Her stroke quickened on his shaft and Tex panted happily. Her mouth hung open slightly now as she watched a couple more swollen inches form a knot at the base of his shaft!

Pam adjusted her grip and employed both her hands. Now one hand griped the knotty ball while the other slid rapidly over the gooy shaft. This caused Tex to wince!

“Oh god, I am so sorry Tex!” Then a quick steady stroke came naturally to Pam. Red veins appeared on the shaft and the tip was purple, which sort of worried Pam a bit. She kept going; as his panting now had a real urgency to it. Then Pam gasped as it throbbed violently in her hand.

The cock was squirting creamy snot in all directions; across her tits, over her face. She squealed and froze in wonderment. Her tongue found a drop on her lip and analysed it in her mouth.
