Lupi's first ever ejaculation:
Junior hit his stride, now, 2 years later, it's Lupi's turn!
Junior and Lupi both purred as they were fast asleep. Today just so happened to be Lupi's 7th birthday. As he slept, he had the weirdest dream a cub his age could have. He was sniffing the air, having snuck into the girl's locker room at school. He took a big whiff and noticed a musky scent in the air. In one of the showers, Petunia was washing the sweat off a good, long phys-ed session, having played doubles tennis with Lucy, Junior, and another girl classmate. Lupi circled around the corner of the shower stall, taking in the salty smell of Petunia as she mindlessly washed herself. Lupi peered down at his penis and it was hard, pulsing out of its sheath and dripping with pre. He swiftly pulled the shower curtain back and cornered Petunia, ramming his dick in her like a wild wolf. Petunia gasped and moaned as she succumbed to Lupi's wild rape, her rabbit instincts overwhelming her before she could even think of Lupi's assault to be bad. Lupi's hips bucked hard as he… awoke to his alarm clock, blinking his eyes open as the sun beamed down in between the blinds of his window. Pulling his sheets off him, however, he noticed his pee-pee was twitching and hard, pitching a small tent in his PJs. "Huh?! MOM! HURRY!" He began to call, holding back tears as his mind was completely overwhelmed with what his pee-pee could possibly be doing. "I'll be right there, honey!" His mom called back. "What's wrong, my little baby?" Said Lupi's mom as she walked in on a familiar scene, her older son having just had his first erection (and ejaculation, thank Dog for birth control) two years to this exact date. "Oh boy! Here we go!" Lupi's mom sighed as she had to know this was coming. "Aww… is my baby grown up?" She cooed to her younger pup. "Idk mom, I woke up and my pee-pee was all… weird." "Welp, as is Barker rule in this house, once a Barker pup has his first woody, it's time to teach him how to be a big dog." She began to unhook her bra and shift down her panties, knowing full well what was about to transpire, again. "Come on, baby, just like when Junior learned, it's your turn." She didn't even blink and already Lupi was stripped clean of his clothes, sitting on his bed staring straight down at his stiffy. He kneaded and rolled it around in his paws, already familiar since he and his older brother had been playing with their pee-pees a lot in the two years since Junior came of age. "Maybe I should've expected this… but he may not need me…" sighed his mom. He was already pulling up and down on his thin red shaft, feeling the new sensations and reveling in the unfamiliar feelings that came with this. His cheeks flushed bright red and his knot bulged, as he rutted himself silly until he winced and his hips bucked upwards, his little penis shooting 3 pearl-white strands of cum which arced up and then straight down onto his shirt. He basked in the afterglow as tiny jets of cum squirted out of him, making a pearly puddle on his bed. By this time his mom had left, knowing somehow he was in "good hands" already.
