Being a horny 15-year-old (almost 16!) with a bad crush I tried to hang around Mrs. B. as much as possible. I went to her office for help with assignments when I didn’t really need it. I took every opportunity to touch her arm to get her attention or sometimes give her a friendly squeeze or hug. She always reciprocated with a smile. I imagined she enjoyed my company.

“Good girl, Brianna!” she laughed wickedly as I involuntarily painted myself with my mess. “Cum for Mommy! Cum on Mommy's cock like the obedient little sissy bitch you are! Now what do we say, Brianna? What do we say?” From her tone of voice, I knew just what she expected.

“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.
