Breed the girl.

You move inside Summer, purring, growling a little as you enjoy the feelings of Summer's pussy wrapped around your cock. Your barbs haven't flared yet so they brought pleasure to her, her body reacting to you with each thrust deep inside her belly. Fuck it feels good to be breeding Summer, pumping your cock into the tabby cat you'd lusted after as a cub.

You are growing closer to orgasm, to that most pleasurable release inside her, pumping her belly full of your seed. You aren't entirely sure how close Summer is but when she begs you to keep going, to make her yowl, you happily oblige, thrusting harder and faster into her, the urgency to breed even stronger now that she's begging.

"I'm not stopping Tabs," you say, growling, leaning forward to kiss her, "not until you yowl. I want you to beg for it, beg for my seed, beg for me to breed you." You want to hear her beg, beg for your seed, ensure that she wants your cubs before you gave them to her.
