Yes

"What do mean... consummate?" Mathias said with a slow carful tone. "It's exactly how it sounds." Mazar replayed, walking closer to the bed Mathias rested on. You don't just get to say a few words and instantly get everything you want. You have to put in a little effort at least." Mazar had closed the gap between them as he spoke. Mathias's heart began to beat wildly as Mazar approach, his scent filling Mathias's nostrils. His flaccid member gently swaying back and forth as he drew near. He didn't retreat as Mazar stopped at the bed. Mathias looked up at the demon towering over him. He locked eyes mazar and saw the burning lust in them. He reached out and gently grasped Mathias's head, running his hand through his hair. Mathias let out a soft moan at the touch and closed his eyes. "What has to happen in order to complete the... consummation? He asked. "We have to exchange blood, Mazar answered, "Then you must drink of my seed. The blood binds you to me as my property and my seed will impart to you the gift of Venus. Only incubi can produce more of our kind." He finished. Realization dawned on Mathias's face and his eyes drifted to Mazar's cock that just so happened to be at eye level with the nude mage, and was beginning to stiffen slightly.

"Well, okay, let's get started, uh sir." Mathis said feeling a little timid. Despite everything that Mazar and Mathias did in the other room he still felt apprehensive. Without the venom coursing through him and clouding his mind he was still not completely comfortable with the idea of being intimate with a male. Even if this was the most beautiful male he and ever seen. Mazar picked up on this. "Now now, don't you worry dear mage. You had the time of your life earlier. I'm sure you'll have just as much fun." Mazar said as a dangerous smile stretched across his face. "Here, let's start with the easy part, shall we?" He said holding out his hand and gesturing for Mathias to extend his. Mathias's reached out to grab ahold of Mazar's hand, his heart beginning to race at the thought of touching such a beautiful and powerful being. Mathias slid his hand over Mazar's and felt his palm. His skin was soft but well worked. He could feel callouses all over that would indicate years or decades of weapons training. Mathias had some in the same spot from his training, though they weren't nearly as developed as Mazar's. As their hand clapped together mazar flipped over Mathias' hand and exposed the pronounced veins of his wrist. Quicker than the flash of lighting Mazar raked the nail of his pointer finger across Mathias's wrist opening up a thin cut. A moment later blood began to pool and over flow from the small, clean tear. Mazar opened his mouth and brought his other wrist up and using one of his overly pronounced K9's, sliced his own wrist. He then rubbed the two bleeding incisions together mixing their blood. Once he was finished he spoke an incantation and the two wounds sealed shut without a trace of their previous existence. Mazar then released Mathias's hand and took a half step back. Mathias's withdrew his hand and inspected his wrist. All of the blood had been sucked back into the cut before it closed... That included Mazar's blood. His wrist felt a little strange. It tingled like the pins and needles of a limb falling asleep. In a matter of heart beats the pins and needles spread up his hand to the tips of his fingers and towards his elbow. Mathias began to breath faster with mild panic. This only caused his heart rate to increase and speed the spread of the demonic blood that was now tearing apart his own mortal DNA and replacing it with that of a demonic entity. His arm began to blacken at the site of the now healed incision. The blackness spread as fast as the tingles but about 6 inches behind. Mathis looked over to Mazar in a panic but Mazar had already retreated to his chair and was nursing a chalice of blood red wine with a diabolical grin on his face and a hunger in his eye. "What's happening me?!" Mathis pleaded, panic beginning to creep into his voice. Mazar didn't bother replying, it's always the same with these mortals. They all talk tough untill something of theirs turns black. He chuckled to himself, waiting for what he knew was coming next.

Once the tingles reached Mathias's heart they exploded to ever inch of his body and the blackness followed. Mathias was aware of several things that happened all at once. First his nipples suddenly became extremely sensitive, so much so that he could feel the heat coming off the fire and the cool breeze coming from under the door. He felt two things shoot straight up from his skull. He moved his charcoal black arms up and grabbed his new horns with this hands. "Oh how pretty." Mazar said approvingly. Mathias's didn't know this but every demons horns were as unique to them as fingerprints are to humans. And Mathias's we're a glossy ebony with silver leaf like veins spiderwebbing up to the tips, which were spiraled like a billy goats and made a full curl before ending in wicked points. They were as smooth as porcelain unlike the ribbed horns of a goat. The third thing that Mathias became aware of was a strange feeling in his chest. It felt renaissance of a hunger for food, but the idea of food didn't seem to matter to him.

Mathias's examined his body and everything seemed to be the same, apart from the horns, sensitivity in his now erect nipples and black skin. Mathias's inspection was interrupted by Mazar's silky voice. "Well now that the easy parts over, let's get on to the hard part." He said rising from his chair. His cock begin to swell and, to Mathias's surprise, change shape!
