Heather once again led Arnold to her room, then put him inside and turned to shut the door.

“Do you want me to kiss it again and make it feel better?” Arnold asked.

Heather leaned her forehead against the now closed door and took a deep breath and let it out. I really want him to. She thought with a smile, then she turned around to look at him. “Arnold, I...” Her eyes dropped down to his crotch and didn't see what she wanted to see, so she stepped close to him and put her hand there, then started to rub him. “I'm really happy that you want to do that to me again.” She kissed him and felt him grow under her hand and broke the kiss. “I want to do it to you this time.”

Arnold gave her a look that could be interpreted as skeptical. “Kissing me there like that won't work.”

Heather laughed a knowing laugh. “Oh, Arnold.” She said. “Different places need different kisses.” She whispered and stood on her toes and gave his forehead a peck with her lips. She unbuttoned his shirt and leaned in to give him a three second kiss on the lips, then she moved down and gave a soft suckling kiss to his nipple, rolled her tongue around it and flicked it once, then suckled it again.

Heather looked up at his face and saw that she had his undivided attention. She smiled and gave him light butterfly kisses down his abdomen and stopped when she reached his jeans. With quick movements, she had him unbuttoned and unzipped and slid his jeans down. She stared at the bulge in his underwear and liked what she saw. She hooked the edge of his underwear with her thumbs and slid it down to reveal him completely.

“It looks like yours is red from rubbing it, too.” Heather said and put her hand around it. She looked into his eyes and she leaned forward and gave the tip a big slobbering kiss. She felt it throb and his testicles contracted from the intimate contact. “Yes, this needs extra special kisses.” She said and kissed it all along the length, then she stuck out her tongue and licked it all the way up to the tip.

Arnold stared down at her and wondered where she had learned so many different kinds of kisses.

Heather saw the wonderment on his face and decided to blow his mind. “Now the best kiss for this area.” She whispered, then swirled her tongue around the tip and plunged her mouth over him and started to suck as she bobbed her head.

Arnold was a fair size, near the top edge of average at about seven inches, so Heather felt like she had hit the jackpot. He was smart, handsome, had a great body, and listened to her without question. She knew that he was going to be easy to mold into the perfect boyfriend, mainly because he was so very close to her ideal man already. That made her a little eager in her ministrations and she felt him start to throb constantly in her mouth.

Oh, shit! Heather thought and her mind raced as she wondered what to do, then she remembered the pair of underwear that she had discarded earlier. In one smooth motion, as if she had practised it, she slid him out of her mouth, grabbed the panties and folded them up, then held them over the tip and jerked him off for the few seconds it took for Arnold to finish.

Arnold's mind was overwhelmed at Heather's 'kisses' and he felt something building inside of him. He had never felt anything like it before and he was about to ask her what was happening, then she stopped kissing him and wrapped her underwear around his penis and pulled on it like it was a toilet plunger.

Arnold took in a sharp breath and then his whole body spasmed and he felt something as it squirted out the end of his penis. It only lasted for about five seconds as Heather kept pulling, then she sighed and bundled up the underwear so nothing would spill out. He didn't even see what it was that came out.

“We almost made a huge mess that I'd have a hard time trying to explain.” Heather laughed and walked over to the bathroom and turned on the faucet on the sink to rinse off her underwear. “I hope this doesn't stain too much.” She swished them around and tried to rub them, then gave up and tossed them into the garbage can.

Arnold stood there with wide eyes and stared at her with his penis hanging out for all to see.

Heather looked back at him and saw that he wasn't taking care of himself and held in her laugh. “You really haven't done that before.” She said and grabbed some tissue paper and walked over to him. She knelt down and gently took hold of him as she wiped at the tip that was still dripping a little. She squeezed it gently and milked out that last little bit, wiped it off, then was surprised as it started to grow again. “I'm sorry, your girlfriend doesn't have time to do that again.”

“Do all girlfriends do that?” Arnold asked.

“The good ones do.” Heather said and stood up, then she tucked him away in his underwear and then zipped up his pants. “I'll be right back.” She said and went to the bathroom and washed her hands, then she used a toothbrush and some mouthwash. “There! All evidence gone.”

Arnold looked down at himself at the bulge still there and then back at her, and she laughed.

“Okay, not all evidence.” Heather said as she buttoned up his shirt, then she put her arms around his neck and kissed him. “Do you want to use the computer for a while?”

Arnold nodded and they went over to it. He knew what to do this time and turned it and the monitor on and waited. Heather thought about sitting on his lap, then thought better of it. She had indulged herself quite a lot today and there was no way she could get away with doing anything else. She sat on the floor and Arnold spread his legs for her to fit between.

I didn't even have to ask. Heather thought happily and looked at the screen as it came on. “Okay, the pages are bookmarked.” She said and showed him how to find the bookmarks.

“Is there something on here to tell me all about computers?” Arnold asked. “I was thinking of getting one myself.”

Heather sighed. I was worried he would want to get one and wouldn't need mine anymore. She thought and clicked on the latest model of computers that you could get in pretty much any electronics store.

“I won't be getting one for a while, because I need to save up for it.” Arnold continued. “I'd like to keep coming here to use yours.”

“Then I'll show you everything you might want.” Heather said, her mood greatly improved. “I think I remember you saying you want to model specimens?”

Arnold nodded. “What do I need for that?”

“I'd say a 3-D editing program for starters.” Heather said and saw his slight confusion. “It's three dimensional computer modelling software.” She said and searched for a quick video on what it was.

“Whoa.” Arnold said and moved forward in the chair, which just happened to press his erection into Heather's upper back. She couldn't help her slight shiver, especially since he was still hard. It made her think about how long he would last doing... other things.

“There are free programs out there, and they are difficult to learn because the interface is so awful.”

Arnold gave her a blank stare and she chuckled.

“You'll understand what I'm saying soon.” Heather said. “Remember what I told you before.”

“You have so much more to teach me.” Arnold said and she nodded.

“After you get a 3-D program and learn how to use it, then...” Heather went into detail about what the whole process entailed. She even brought up some tutorials for how to do the basics of 3-D model editing, from altering an existing model to creating your own from scratch.

“Can't you just... take a picture or something?” Arnold asked. Like a lot of people, he wanted his specimens to be instantly accessible.

“They do have 3-D scanners; but, they are expensive.” Heather said. “Although, there are plans to make your own online.”

“Can you show me those?” Arnold asked.

Heather quickly showed him how people had used mirrors and motion capture software and a game system camera to make a 3-D model. The quality was pretty low and Arnold quickly lost interest in that avenue. He would either have to find the specimens already made as a 3-D model or make them himself. He knew that was going to take time, though.

“There are kind of cheats for it, so it's not really all done by hand.” Heather said. “Can I show you some of them?”

Arnold nodded and she brought up a basic drawing of a circle.

“This is a circle, right?” Heather asked and he nodded. “Okay, well... it's not just a circle.”

“Huh?” Arnold looked at her and then at the screen.

“It can also be a sphere or a dome, or even the end of a cylinder.” Heather said with a smile and brought up an image of each. “If they are seen from a certain angle, they all look like basic circles. Except for the sphere. That's completely round and always looks like a circle.” She said. “It's called 'perspective' and all those things you see inside a specimen? They are all just circles, ovals, triangles, squares, and rectangles. It's a trick to use when trying to make sense of something complicated.”

Arnold watched as Heather brought up one of the pictures she had saved and opened a basic paint program and used the mouse to draw a circle around one of the exposed organs, one around the heart, then an oval around a lung and then a liver. She drew a rectangle around the intestines because she didn't feel like drawing a bunch of ovals. Arnold looked at the screen and then at her, then back at the screen. He had never seen them like that before.

“When making them in a 3-D program, you just use a circle for this part, and oval for this part, and so on. Once you have the basic shapes, you can alter them and make then more detailed and even add the real picture to color them up properly.” Heather said. She had read a lot about it in a tutorial she had found online and she looked at Arnold's face. She saw astonishment there and was glad that her hard work had paid off so soon.

“Can you get one of these 3-D programs?” Arnold asked.

“I got one last night.” Heather said. “It's a little slow when you try to render a scene...” She stopped talking when she saw his attention shift. “I'll just start it up for you.”

Arnold let a smile out as the screen changed and the program loaded. When it finished, the screen was filled with a lot of buttons and things that he had no clue about.

“It's a lot to take in, I know.” Heather said. “This is why I told you that the interface on them is horrible.” She chuckled. “I want a big button that I can click to do the work for me and not have to search through a dozen menus to find the one thing I want to do!”

Heather clicked through six menus and chose an option for 'create sphere'. A ball with shading appeared on the screen, and she clicked on it and moved it around. Then she moved through the menus again and chose an oval shape and it dropped on top of the sphere. She clicked it and moved it off to the side.

“You can keep adding them and can make any structure you want.” Heather said and clicked on the sphere and then used an option on the side menu to made the sphere editable. A whole bunch of little dots appeared on the surface and she clicked on one and moved it to the right a tiny amount and the sphere changed shape slightly.

Arnold watched her stretch out the sphere and then then she added a square and joined the circle and the oval together. “How are you doing all of that?”

“Hours of hard work and studying.” Heather said. “Kelly helped me last night with finding the best free program and sorting out the garbage in the online tutorials.” She turned and looked at him. “I wanted to make sure that I could show you as much as I could.”

“Thank you.” Arnold said and leaned forward and kissed her.

Heather put her arms around his neck and made out with him. She really liked that she didn't have to ask this time and enjoyed the feeling of his lips on hers.

*Knock* *Knock*

“Hey, you two.” Claire said through the door.

“It's open.” Heather said as she broke the kiss.

“It's getting late.” Claire said and saw that she had just interrupted them.

“I was just showing Arnold some of the 3-D editing things Kelly and I found last night.”

“Really?” Claire looked at her daughter skeptically and Heather stood and waved at the screen.

“Arnold just thanked me for doing it and showing him.”

Claire was a little surprised that she hadn't caught them in a more compromising position. “Well, I need to take him home, so save up what you're doing and come downstairs.”

“We were just playing with it, so there's nothing to save.” Heather said as she turned around and bent over, then closed the program.

Claire looked at Arnold's face to see where he was looking and his eyes were firmly glued to the screen and at what Heather was doing and not looking at her ass, despite it being right in front of his face and in a pair of short shorts. This surprised her, since most women used their bodies to get a man's attention.

If my daughter can walk around like that and he didn't take the obvious hint to look, then how did she gain his interest? Claire asked herself.

Heather shut the computer down and stood up straight, then turned to look at Arnold and saw that he was looking up at her face. She didn't see any guilt there, so either he had gotten a really good look and liked what he saw, or he hadn't taken the hint and didn't look at all. She suspected the latter, mainly because he hadn't looked at her when she walked around bottomless.

Why would he try to sneak a peek when I had both underwear and shorts on, after seeing me with my legs spread wide for him? Heather asked herself as her face flushed red and she smiled down at him. She gave him a quick hug, then walked over to the bed and tried to pick up his backpack. “Ugh!” She grunted and could barely move it. “What do you have in this thing?”

“Everything.” Arnold said and walked over to the bed and picked it up like it was nothing and slung it over his shoulder. “I didn't know what homework was assigned so I have all of my school books in it.”

Heather had surprise on her face. “All of them?” She asked. “I didn't think you could fit all of our books into a single backpack!”

Arnold smiled. He had been packing things into spaces for nearly all of his life. A few rectangle shaped books into an oval backpack was one of the easiest things he's packed. His thoughts paused on what he had just thought. He had immediately assigned shapes to the objects he was thinking about. He stepped close to Heather and put his arms around her.

“Thank you for showing me that seeing the shapes trick.” Arnold said and kissed her.

Heather completely forgot that her mother was right there and kissed him back. Her arms snaked around his neck and she let her feelings control her actions and not her brain.

Clare stood there for a few moments and watched them making out. She let it go on for nearly a full minute, then she coughed. “Ahem.”

Heather jumped like something had bit her behind and broke the kiss. “Mom!”

Claire had to hold in her laugh. “Arnold, I need to get you and your mother home.”

Arnold nodded and let Heather go.

“Goodbye, Arnold.” Heather said, so he leaned in and kissed her for three seconds like always, even though they had just kissed.

“Goodbye.” Arnold said and walked over to the door and past Heather's mother, then he went down the stairs to wait.

“I'm sorry, mom.” Heather said in a low voice. “I didn't mean to... well, he kissed me and...”

Claire had to laugh this time. “I saw you, so it's okay.” She said and saw her daughter relax. “You just need to be careful what you do with him, all right?”

Heather nodded. “I promise I'll be extra careful.”

Claire nodded and left her room. She was impressed that he had done that in front of her and wasn't ashamed or even apologetic about it, which confirmed that he was as straightforward as anyone could possibly be. He didn't see anything wrong with making out with a woman's daughter in front of her, so he wouldn't think anyone else would, either.

Claire let a smile show on her face as she went down the stairs. “Have you all got everything?” She asked Annie and Arnold. Both of them nodded, so the three of them left the house and climbed into the car. She drove them home and pulled into the driveway.

“Thank you both for coming over tonight.” Claire said. “It was nice having some adult company for once while Heather had someone over.” She chuckled. “Last night it was Heather and Kelly running all over the place!”

Annie had to smile at that. She could just imagine what it was like to have a couple of teenage girls tearing her house up while they carried on. “It was nice to get out, even under the circumstances.”

Claire reached over and took her hand. “You call me at any time if you need to talk.” She said. “You know I understand.”

Annie took a breath and let it out, then she nodded. Claire let her hand go and Annie got out of the passenger side and took the large plastic container of food with her. Arnold opened the back door and got out himself.

“Arnold, come here for a minute.” Claire said and made a wiggle motion with her finger, so he came over to the front door and leaned in. “I suggest you wear old clothes that you don't mind getting dirty tomorrow.” She said and saw Annie walk to the front door of their house. She knew this would be another good time to test Arnold, so she spoke what she thought were the magic words. “Goodbye, Arnold.”

Arnold took the cue and put a hand behind her head and kissed her for three seconds. “Goodbye.”

Claire was a little stunned at how well he had kissed her. That... was a spectacular... confirmation.

Arnold closed the car door and walked towards his house and Annie waved to her, so she waved back.

As long as Heather wasn't around, which was the only restriction I gave him, he will kiss me whenever I say goodbye. Claire thought, then thought of something else and rolled down the car window. “Oh! If you have work gloves, you can bring those, too!” She called out to him.

“Okay.” Arnold said and shut the front door.
