“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.

“I love that part so much!” I purred. “The way his knot pulls against my entrance as he's thrusting! Holding him inside so he can't pull away!” I shuddered with arousal, imagining just how I knew it felt as I watched it happening to my own mother instead. “You should play with your clitty, Mom,” I told her. “Brucie's way faster to cum than Daddy is—you probably won't be able to get off on the fucking alone, not unless you help yourself out. In fact...” I thought about it, then moved to act, resting my palm on her mound and using the tips of my fingers to tickle her clit. “Actually, never mind; I'll do it for you this time. You just concentrate on how good it all feels, and try to let yourself cum!”

“What?” she gasped. “What are you talking about? You both just let me out of these ropes right this instant!”
