Making the Quiet Boy go loud

Even thought the two young sincubi enjoyed fucking each other, eventually they wanted more. "Thank you for this gift mistress... I shall put it to good use" she said while stroking her crimson cock. As she got out of her apartment she put on a glamour of her old mortal self. ...With some improvements. Looking slightly younger and with blemishes on her skin gone. She even had more spring in her step and she practically glowed with confidence.

Soon she was knocking on the door of the young man who had turned her down one time too many. There may have been plenty of other prey to choose from, but this conquest was a matter of principle! Toby eventually opened the door when Gabriela rang the doorbell, though he looked sleepy and had been clearly roused from bed. "Hi ma'm. It is really late and I'd love to be of help but wha-" he was caught by surprise as Gabriela barged in and slammed the door shut behind her.

Gabriela pushed him against a wall. "Alright hijo, I've been patient with you, I've been nice, but I will have you and after being reborn as this..." she dropped her glamour and her victim recoiled at the sight of the crimson demoness but wasn't strong enough to escape her grasp. "Do you like mamacita's new look?" She shook her massive breasts at him. Even this shy and far too innocent boy couldn't help but stare at the massive red boobs and Gabriela rewarded his curiousity by smothering him with them. Toby's struggle was muffled by the soft red flesh pressed against his mouth. "See what you've been missing out on!" Gabriela laughed cruelly as her victim's struggle against the pliant flesh prison waned. "Good... Good... Just let mamacita take care of you..." She pushed him back against the wall but this time she slid slowly down, scraping her nails against his clothes and tearing them up. His cock was rock hard already, clearly affected by her daemonic pheromones and aura of lust. "MMmm... I've been waiting for this dick..." Gabriela's black tongue wrapped around the cock and the man whimpered. "Ma'm! AH! AH! AAAH!" Gabriela had been proud of her head game when she was a mortal, and now she was even better. Toby practically melted at her touch. Bending over and holding onto her horns for support as she sucked him for all he was worth. She enjoyed seeing his legs twitch and threaten to give out under him. But she did not reward him by letting him cum inside her mouth.

When she let his cock free with a pop, Toby almost started to cry. "Please ma'm! Don't stop! Don't stop!" The sincubus grabbed his cock hard. "What's my name?" Toby seemed confused. "Mrs. Lopez?" "Nah, when I'm sucking your cock and about to fuck your brains out, I am not Ma'm, I am not Mrs. Lopez... I am Gabriela. Now, beg for me. Beg for Gabriela to make you cum!" Toby nodded enthusiastically. "Please Gabriela, make me cum. Make me cum..." Instead she pushed him face down on the floor and moved behind him. Looking back in fear, he finally noticed the massive sincubus cock she had grown. "Not good enough... I guess I'll have to make you scream my name..." She rubbed her cock against his ass cheeks. "NO! NO! Mrs. Lopez, don't!" "No no no... What did I tell you to call me?" She placed the tip of his cock on his virgin asshole. "Gabriel-" she pushed her dick inside "AAAAAAAAAAAH!" her victim screamed. Gabriela held on to him by his ass as she fucked him. Soon Toby's screams were changing tune. He was pushing his ass back at her. Drooling and moaning each time she slammed into him and her red balls slapped against him. The sincubus pulled his head back while going in as deep inside him as she could. Toby had tears in his eyes but his body had betrayed him and was thoroughly enjoying the sincubus dick. "Do you want this sincubus dick inside you boy?" Finally his voice hoarse from screams and moans, Toby could only nod weakly. "Good..." Gabriela's tail wrapped around his hard shaft, making him shiver again at the double pleasure of getting penetrated while the sincubus played with his cock. "Now, be a good fuckboy and ride my dick until you cum for me..."

Gabriela laid back and Toby did as he was ordered. Bouncing on the cock happily. When the corrupted and tainted mortal finally succumbed to his pleasure Gabriela also came, filling him up with her sincubus cum. Toby's transformation was slow. He fell onto the floor, twitching and moaning as his body began to change.
