That Night after the Situation with Lilly and the Beast.

Callie awoke and felt Mark holding her. She still had a few bruises from the beating she had taken from Mark's ex-whatever she was. But the pain was not what was keeping her awake it was the hurt and heartbreak she saw the day before in his face and eyes when he found out that she was having sex with numerous other men. She did not want to hurt him emotionally like that but physically was another matter. So, after she discovered he had a slight interest in Jacoline she had decided to no longer let her demon side influence her to have sex with others. Looking up at him she smiled slightly. Mark was hers and she was his. When she felt Mark begin to stir slightly she pulled him closer and held him tighter. Listening to his heart beating. Which slowly allowed her to fall asleep.

As the sun began to rise Callie awoke and she knew Mark was awake already.

"Good Morning." He said as he smiled down at her.

"Morning." She replied but made no motion on rising and held him; not really wanting to move. She liked holding him and did not want to get up yet. Secretly she realized that she liked this just about the same as having sex.

"Should we get up and have breakfast?" He asked as he felt her tighten her hold on him.

"No, I want to stay here for a little longer." Callie answered as she closed her eyes. An hour later she reluctantly got up and nudged him to wake up. They had to go to work soon and neither was ready to go. Stepping in the bathroom Mark started to shave and brush his teeth. She waited a minute to check her phone. She had fifteen messages from unknown callers contacting here for meaningless sex. Frowning she activated the block feature on here phone and said quietly "No More." Then went into the bathroom. She stopped briefly to brush her teeth then slipped into the shower to have some shower sex with Mark.

Slowly walking into work Callie held Marks hand and felt that he was not really paying attention to her.

"Do you want to have lunch with me at eleven?" She asked as she watched him falter slightly and turn towards her trying not to look at her in the eyes.

"How about at one? I have an appointment at eleven." Mark said as he looked down at his feet looking a little distracted.

"That will be fine." Callie said through clenched teeth watching him walk into his office. Wondering what type of appointment, he could have and why he was so distracted. Standing there a few seconds, she decided to follow him to see what he was up to. Fearing the worse.

At eleven Callie flew high above Mark looking down at him as he walked quickly towards one of the nearby buildings. As he ducked into a six-story building she landed as he crossed the lobby heading for the elevators. She watched as the elevator rose and stopped on the fifth floor. Snarling she took to the air and circled the fifth floor considering the windows trying to see him. When she finally spotted him, he was sitting on a chair watching a video while an older woman talked to him. She could not hear but she felt her rage increase. Growling with homicidal rage she smashed through the window and watched as Mark spun in the chair with surprise and then embarrassment shone on his face.

Bellowing Callie screamed. "How could you!" As she grabbed him hauling him into the air high above her. "You told me that you are only interested in being with me! That you are committed to me and only me!"

"It isn't what you think." Mark tried to explain as she pressed him against the ceiling. "She is just teaching me." He said as his face started to turn red with embarrassment.

"Teaching you what?" Callie asked angrily glaring at the older woman.

"Sexual Techniques." Mark said as he frowned slightly. "I though perhaps if I learned to pleasure you better than you might not need to have sex with anyone else".

Callie looked at the video then the chalk board when there were numbered steps under a lectured lesson plan. She read the title and almost dropped Mark. "Techniques to Sexually Pleasure your Mate." Staring dumbfounded she carefully set Mark down.

"That is right young lady. I am the instructor Doctor Beth Butler. Mister Lillie asked for me to instruct him in sex." The older woman said as Callie looked at her with wide eyes.

"I do not know what to say." Callie said quietly as she took Marks hand. "I am so sorry I overreacted."

"I wanted it to be a surprise." Mark said somewhat embarrassingly as he looked at Callie.

"Well I feel like a complete idiot." Turning Callie looked at the Doctor. "I will pay for the window of course". Quickly giving Mark a kiss she walked over to the window. "I guess I will go back to my office. I'll see you at One for Lunch." Then Callie dove out the window flying back to her office.

At One Callie waited impatiently until Mark knocked and entered her office. She hit the remote door lock and did not know what to say at first so she stood and moved around to lean against her desk. "So how was the lesson? You learn anything?" Callie asked as Mark smirked and stepped closer to her.

"Well I learned a few things that you might like." Mark answered as he kissed her lightly. Moving his hands down to squeeze her ass. Pulling her closer. Then he started to kiss the side of her face, down to the neck and finally up to her pointed ear. Stopping to nibble on her ear. All the while squeezing her ass pulling her towards him.

"Oh, I like that." She moaned in his ear as he continued to kiss and nibble up one side of her head and down the other side. Stopping to kiss her horns as he made his way. All of this was driving Callie crazy. It was all she could do from not ripping her and his clothes off. When she was about to lose control, Mark stopped.

"Do you want me to continue?" Mark asked as he looked at her.

"Yes, please do not stop." Callie hissed as he started to remove his clothes then slowly took off hers. Then moving in he started kissing and nibbling on her again. In moments Callie was so excited that she now had lost control. "Take me, Take me now." Callie purred as Mark took her on her desk.

An hour later Callie picked up her clothes and started to get dressed. Mark had sat down on one of her chairs and was finishing buttoning his pants.

"That was incredible." Callie related as she moved over to sit on his lap putting her arm around his neck. "And that was just lesson one?'

"Yes and no. That was only part one of lesson one. There are three more parts." Mark said as she stared at him.

"Part one, Ok, let's go." Callie stood and took his hand. Leading him out of the office.

"Where are we going?" Mark asked as she headed for the large nearby window.

"Back to my place. We are going to try those other parts and if they are as good as this time then there will be no problem for me to only have sex with you." Callie said then noticed Mark had stopped.

"What?" Mark asked as he saw her turn back towards him.

"I have decided that I want to be committed only to you and only have sex with you." Callie said as she watched Mark smile broadly.

"But what about your demon side and the need to have numerous sexual partners?" Mark asked as he looked at her lovingly.

"What I need is you and only you." Callie said as she squeezed his hand. "And if you continue to improve with these techniques I could love you more than I do now."

Mark beamed then looked at her in shock. "Are you saying that you love me."

"Of course. I love you, you dolt. Now come on so you can show me those other parts and I can actually be louder than before". Callie grabbed him and flew out the window towards her apartment.
