"Play" with the dog

Futaba left Sae there for a moment and retreated back to Kawakami's room, grabbing something from the nightstand.

She returned holding it behind her back.

"Saaaaeeee. Be a good girl and hold still for a second" she said in a sing song voice, as Sae effectively froze in place.

Futaba approached from behind and inserted a vibrator into Sae's pussy. She didn't know what it was when she had looked yesterday... But a little "tutoring" from Kawakami before Sae showed up helped.

"Awo?!" Sae yipped in concern. But Futaba activated the vibrator before Sae could even so much as turn to face her.

"Hrr.. hrr... Hrrr... Hrr..." She began to grunt from the pleasure. "Arrr... Hah... Hah... Hah..."

Her tongue dangled out of her mouth. She wanted to run, but the pleasure in her pussy was too much.

Futaba sat down and began to stroke her hair.

"Awww. Who's a horny puppy? Sae is! Yes she is!" She teased.

"B-borf! Hah... Hah... Borf!" Sae managed to squeeze out some barks between the pleasure.
