Katherine always started with a lick. Her tongue slowly moved along the flaccid shaft, coating the surface generously. She graciously swallowed the tip between her moist lips, letting the soft head push through her parted mouth. She did most of the work, as usual, and started to move her head in and out of his hardening cock, feeling it grow inside her. She loved how he became larger inside her, expanding in both length and girth, forcing her to loosen her jaws in response. He stood there as she eagerly continued to blow him. He never said anything, which she was perfectly fine with. She only cared about one thing, which he always managed to deliver.
After a few minutes, Katherine carefully slid herself out from under him, and got on her hands and knees. She confidently arched her well-toned back, and flexed her athletic thighs as she spread her legs open. She waited, patiently. She always did, as he would only approach her after she had resumed her position. There were days he would simply walk away, leaving her in her place. Fortunately for Kat, today was not that day. She excitedly moved her long, dark hair to the right, and stretched her wet slit with her fingers as she watched him approach her from behind.
He was always awkward at first, especially when it came to the actual penetration. Lucky for both of them she was quite used to this situation, and happily guided his erection towards her pussy. She gently pulled his tip into her, and he quickly found balance with a firm hold of her back.
In seconds his body overtook Katherine from behind. He dug into her, clawing her back as he carried on pumping inside her. She hungrily pushed her hips into him as well, wanting to savor every inch of his mighty rod.
After a few thrusts, and without warning, his cock exploded inside her. She yelped, and her whole body flinched and trembled in response to the sudden release. Both of their legs shook from the intensity, and eventually gave up. She waited again, patiently, for him to grow smaller again before pulling him out. He remained silent, with occasional panting and howling, which she was perfectly fine with.
“Good boy…” she whispered before kissing his cheek softly. He happily responded with a wet lick of his long tongue before resting on her bare body, his tail lifelessly on the floor in which they now laid together.
