Paul was a bit frazzled by the experience of posing, well... performing for his mother and aunt. He was not ashamed, but felt rather awkward about being naked and post-orgasmic. He looked for his tee shirt and shorts to put them back on, but didn't really want to get dressed.
"We need to have a robe here for you between sessions," Eve said helpfully to her son.
"I need a cold shower" Chris said, buttoning her blouse again. "That was very hot."
"So, Aunt Chris, you meant it when you said looking at me made you horny?" Paul asked, trying to sound innocent. He was still naked and his cock was fat from being hard and exercised.
"Yes, dear. Every word of it. You are a handsome and hot young man. I may be your aunt, but I am still a woman," she replied with a gentle smile. "I love you, Paul, so I want to be sure that you understand my comments were to help you and your mom get these photos right. It is what I do for a living. I help people express their sexuality."
"Well, you sure helped him do that!" Eve chimed in. She smiled at Paul again and winked.
"Mom, I need a break. I am going to get a coke. I'll be back in a minute." Paul started to leave the studio with his clothes in his hand. He just walked out the door and up the driveway. It didn't really matter since they were on the farm, still it amused his mother that he was so casual.
"See? People like it when they are free to be and do what they want," Chris instructed.
They looked at the images Eve had transferred to the monitor. She quickly deleted ones that did not meet her standards for art or precision. The finished file had some very hot images of Paul. He came back in with a towel around him just as they were saving the file.
"Wanna see? There are some really nice shots here," Eve asked.
"Maybe later. I'm good now." Paul seemed completely back to normal. He was a young and virile young man, after all. He may have recovered even faster than the women who were not so exercised.
"Well, let's try something else, shall we?"asked his mom.
"Sure, like what." Paul replied and leaned against a chair.
"Well, I was thinking about something a little less emotional to begin with. You are such a handsome boy, I mean, man, that it would be good to get some pictures of you relaxed. Naked of course, but natural,"Eve suggested. "We can start with you there, leaning against the chair with your towel on. Let me get the camera."
Eve walked around taking pictures and looking at him. "Okay, take the towel off and just relax."
When Paul dropped the towel, his mother inhaled a bit and pulled the camera back to her face. He was gorgeous. His penis hung low and long. His ball sack was sagging and his balls seemed heavy. Not more than 45 minutes earlier she had watched him shoot hot loads of semen directly at her camera. Still the sight of that relaxed penis on her handsome son, just got to her.
She snapped shots of him from all around, again focusing and then zooming out. Paul was fidgeting. "What's wrong?" Chris asked.
"Well, I have to pee," he replied.
"Okay. Pee." His mother said flatly. He gave her a quizzical look. "Seriously. This is the stuff that life is made of. I want to shoot it."
Chris liked the idea and looked for something for him to empty his bladder into.
Eve set the scene. "Chris, I want you to kneel next to Paul, flat on your shins, very prim and proper. I'd rather you have a skirt on, but the shorts will do. Pull them up just far enough to show your knees. Sit up straight. Paul, stand next to Aunt Chris; you, too, very straight and tall."
"Hurry up, Mom, I have to piss like a race horse," Paul complained.
"Well, do what I say and you can. Chris. reach up with your right hand between Paul's legs and grasp his... (she swallowed) his... penis. You are going to aim him for us."
Chris was curious and Paul was in agony. She threaded her arm between his muscular legs and grasped his cock, wrapping two fingers over the shaft like a pitcher readying a fast ball. The rest of her hand rested, curled against his balls. She felt Paul start to fill. Her red nails gleamed on the surface of his cock.
"Okay, that is perfect," exclaimed Eve. Chris look at me. That's right. Okay, Paul, any time. Chris just aim his stream out about three feet in front of you."
"You mean, you want me to pee on the floor?" Paul asked incredulously.
"It's okay, son. There is tile underneath the drape and we can wash it up later. Now, get going."
Paul shrugged his shoulder and tried to relax enough to urinate. It was difficult with his aunt holding his cock. Somehow the fact that making erotic art is not all that erotic., helped him. Chris did not stir or excited him any more than he was.
A drop or two came out of his penis. It was a mix of pre-cum and urine. Then the stream started in earnest. A hot, clear flow of piss poured forth and landed in front of him. The relief was immense and he closed his eyes. "Open your eyes, Paul. Look at me," Eve instructed.
Chris began to move his cock from side to side giving the camera a chance to record the S-curve his arcing piss made. She, herself. was feeling wet between her legs.
Paul had a very full bladder and Eve was able to take many shots, even one that seemed a little blurry due to the long open shutter time.
When at last Paul was finished and pumped the last of his urine out, Chris remained fixed in position. Paul's cock had deflated and she wanted to see him get erect again. After all, she was merely a model and needed to wait for the artist to tell her what to do. Paul didn't mind either. From his position, he looked down and had a view of his aunt' cleavage and her hand curled around his cock. Why break the scene? he wondered.
Eve checked the camera back to make sure the shots were recorded and called for them to break the scene. "I have another idea. Chris, you better drink a lot of water. Paulie, that was wonderful. You can relax for a bit. We are going outside next."
