“Good boy, Brucie! Good boy!” I encouraged him, ruffling his neck. “Mommy's turn this time!” And with a tongue-lolling doggie grin, he finally made his move, jumping up onto Mom's back and starting to thrust himself at her. She gasped in some combination of surprise, doubt, and fear, and I took her hand in mine, giving her a reassuring squeeze. “Try to get a little lower, if you can,” I advised her. “If you let him get all four paws on the ground he'll be way less likely to scratch you with his claws. It'll feel better, too, if you give him more leverage for thrusting.” She did as I said, lowering her hips and pressing those huge, hanging tits firmly into the carpet, her eyes clenched closed as she waited for it to happen. Bruce was having a little trouble finding his mark, as he always did, so I reached in under her with my other hand and spread her thick, meaty lips with my fingers. That got it done, her eyes popping wide as that hot doggie cock finally slid inside. His claws scratched at the carpet as he tried to reposition himself, giving himself one more deep, forceful drive into her depths.

“You like that, Uther?! I’ll never stop! Throw your best fighters at me, and I’ll throw them back in pieces! I am invincible!”

I started gently rolling my hips, proving my words. She was still stubbornly refusing, mouth tightly closed as I painted her face with my cream. But as Daddy snuggled up behind me and started playing with my titties again, staring encouragingly down into her eyes over my shoulder, she finally started playing ball. She was still tentative, just a tiny, testing little lick of her tongue darting out between her lips, but I rewarded her with a happy little moan and stopped grinding myself on her face. The tongue came out again, and again, and the more I responded to her the more confident she became. I still wasn't ready to let her out of her restraints yet, even once she started eating me for real, but I was definitely enjoying myself, clenching my muscles to try to squeeze out as much of Daddy's cum as I could. That was the one and only problem with Daddy having such a big cock; he always deposited it way far up in there, and trying to get it out again was just about impossible before it was ready to leak out on its own! Still I was doing what I could, and Mommy seemed like she had finally gotten out of her own way enough that she was able to enjoy the taste. She wasn't half bad at it, either. Not as good as Daddy was, judging from the few times he'd chosen to use his mouth on me rather than his cock. But still, not bad, and I was gradually drawing closer to the edge. It hit me more gently than the ones Daddy had given me, but it was no less enjoyable, making me gasp and twitch as I relaxed back against his chest.
