She was a gorgeous little Labrador pup, nearly three years old at the time. Her fur was a uniform buttercream-yellow, ears flopping whenever she turned her head quickly. And her dark brown eyes were large and rather soulful when she begged for a cookie. Her clothing consisted of a white diaper with little blue pawprints all over and nothing else. So naturally her babysitter, a sixteen-year-old golden retriever, made a deal with her. She was already accustomed to his hands slipping into her diaper to rub her vulva; this time, however, he would do so with the diaper off—he even set up a camera so she could be a little movie star! So the young pup stretched out on a pillow, her legs spread, as he undid her diaper and unfolded it. She hadn't yet wet it, so he leaned down to lick her between the legs. She giggled, of course, as his long canine tongue lapped over her equally-canine vulva. After a few minutes, the boy sat up again and unzipped his shorts, letting his half-erect penis hang freely. He scooted closer, until his cock was able to rub against her groin, and let it lay there as he pulled the camera closer. His penis spurted pre as he began to rub it along her groin, the drops of clear fluid splattering onto her stomach and chest. The older dog gasped a minute or so later as he began to unload his seed all over her, some splattering on her face in addition to chest, belly, and groin. Cleaning up didn't take long, either, and was as giggly as the first round of licking. Afterward, however, the golden retriever was hard once again. This time, he sprawled on the pillow while he positioned her over his penis, the very tip of which was now nestled between her vulval lips. He pulled her down slowly, believing that she would be able to accommodate everything but his knot. She started to whimper with barely an inch of penetration. By this point, however, his loins had taken over, so she continued to sink onto his cock. The whimpering gradually turned into sobbing, and finally became loud cries of pain as the teen's shaft stretched her vagina almost to tearing by the time he hilted. He rolled over, gripping her hips firmly as his own began to rock, his penis pulling out and pushing back in as he started to fuck her. It didn't take long for him to finish in her, his knot slamming futilely against her vulva as semen erupted into her depths. He looked up to check on the camera, and noticed that he had unintentionally given his potential viewers the best possible angle on his deeds. The golden retriever withdrew from her vagina slowly as he continued to fill her with his seed, some of it drooling out of her reddened vulva. As his penis came free, he was already moving, presenting his cock to her muzzle even as he bent almost double to lap up his mess. Too sore to really think about it, the poor girl began to nurse on the oddly-shaped paci she was presented, swallowing by reflex the fresh spurt of cum that spilled into her mouth as she did. Slowly she began to calm down, the trauma soothed by his tongue working over her vulva and digging his seed out of her vagina and by her instinctive nursing. He managed to bring her to orgasm fairly quickly, the young body spasming underneath him during her brief eternity of nirvana. He pulled his cock and tongue away from her lips, then sat up and hid both their genitals away. He wiped her face clean of snot and tears, then picked her up and carried her into the kitchen for that cookie she was promised...
