She chuckles lowly as she turns toward the couches, and he follows her to her seat. There he takes his place in front of her armchair, arching his back and opening his mouth wide, as she gently sets her feet upon him. Soon enough, he feels the sensations she commanded him to.
Two large invisible dicks move inside him, known only to the two of them. They push against his most vulnerable places, subjecting him to the relentless, robotic violation that only his own imagination can conjure. Except he could never have imagined this particular torment. He endures it without variation or climax, his own phallus stiffening with the false stimulation for all to see. He suffers this humiliation because she commanded him to, because it amuses her, except now he does so as simply a piece of furniture, a footstool. He can hear nothing except the gentle moaning of the two women on the table, and he has a clear view of them as well.
They are not subjected to a Geas, so they can only do their best to follow the instructions of their masters' superior. The buxom one seems to be struggling to hold herself up by the elbows, her breasts pressing against the smaller one's stomach as her thighs smother her face. The thin one's feet are hovering in the air, toes curled with ecstasy as little moans chitter from her stifled mouth. Their tongues, once tentative on strangers' genitals, now lap eagerly in mutual pleasure. Fragrant juices drip from their faces and into dark pools on the silks beneath them. Hungry hands reach for the curves of breasts and the smalls of backs and the fats of asses. The top girl's shoulders clench as the bottom girl writhes beneath her, their quiet sighs and groans acting almost as music behind the mild conversation on the other side of the room.
It is the frail one that earns the first orgasm: sharp intakes of breath, surely full of her partner's oppressive musk, preceding a long shrill squeal of delight.
"Don't stop," the yath'tallar reminds them flatly, between other words. And even before she can entirely catch her breath, the slave's mouth is already back on the other one's pussy. What is worse, the footstool wonders: to be compelled to serve, having no control at all, or forced to, out of one's own desperate effort not to be punished?
Later on, the gemstone button is pressed. The plugged man emerges on weak knees, moving as quickly as he can as he is summoned for the umpteenth time. "A plate of berries," is requested by a drow man whose only jewelry is a few thin platinum chains hanging over his exposed chest. With a tight nod, the slave moves to fetch them, but the guest accidentally places the disk upside down.
This leaves the button pressed indefinitely, which no one seems to notice. The slave struggles to continue, but does not dare correct anyone; each step is ecstasy and agony as the plug rattles forcefully inside him. His cock stretches in his thong as he carefully places the berries on a porcelain plate, and it is all he can do not to crush the delicate thing as he trembles back to the group.
