"Argh!I...can't...hold out...much longer!"

As the surges of stimulation continued to assault her brain,she clenched him tight inside her,her every orgasm gushing liquids around his tentacles and cock.
He was going to cum in an explosion of pleasure and he could do nothing to stop it.

Isabel continued to gasp and scream her gasping cries of pleasure. She heard his gasping words, and she trembled harder, "y...yes... ahhhh!"

With another thrust into her tight body she arched even harder before, a strong continues orgasm rippeling through her body, she continued to cry out shuddering hard, her orgasmic fluid poured constantly down his cocks as she came continuslly.

Ethrach came hard inside her shuddering,arching body.With the tentacles and cock plugging her hole completely,there was nowhere for his sticky fluids to escape and they gushed into her frame like a waterspout.
Her belly swelled with each throbbing spurt from the appendages filling her as well as the cock.He yanked his penis free from her cunt and shoved it into her mouth,pumping more and more of his seed into her mouth.The tentacles thrashed as they emptied their last inside her,the heads wriggling around as they spurted.

Isabel screamed feeling her body stretching to accept the white sticky cum filling her up inside her cunt, her body still writhing in the throws of exstasy. She gasped as one of the cocks left her body, a large amount of cum gushing out of her cunt along with it. Her mouth was then muffeled with his cock and she sucked on it, mindlessly swallowing and sucking as it coated her face and mouth in sticky fluid. She writhed, with muffled moans as the cocks wriggeled inside her spasming channel, her orgasm slowly coming to and end.

Ethrach relished in the final throes of pleasure as his new favorite artist sucked deeply on his cock,draining the last of his seed.He would not likely forget the honor she had done him this day,but wanted to leave behind a memento for her,for when she woke up.
She had passed out from her exertions and he laid her down gently on the grass.
Stepping away,he began to weave pure energy into matter.The shimmering material that took shape was softer than the purest silk.As he began to shape the material into a garment,he chuckled softly at what it would do to her skin as it rubbed against.

Let her find out that surprise on her own...

He laid the garment down next to her and left the space quietly.

Artistry deserved rich rewards in his opinion.
