In the previous chapter the teaching of Eric continued. Not only was he allowed to fuck me, but Inga and I gave him a lesbian sex show to teach him how women wanted to be caressed. It ended in a threesome where I pleased them both at the same time while they hugged each other.
Since we had started our activities in early afternoon Eric had plenty of time to recover long before bedtime. Inga begged me to let him take me in the ass which I was most happy to do. Inga took over doing the teaching showing and telling Eric how to fuck a woman´s ass. She directed both of us and it became a marvelous ass fuck.
Afterwards Eric was exhausted and was sent to bed. But Inga wanted to talk so we stayed behind. Inga revealed that her late husband had been a fantastic ass fucker and that they had made replicas of his erect cock. I suggested that she should have one made of Eric´s as well.
Eric came to my bed in early morning and took me thoroughly twice in a row. But then he was totally spent and went to sleep in my bed. Inga and I had breakfast alone and then she asked if I was willing to help her take the imprint of Eric´s cock. Of course, I was but said that it had to wait until Eric had recovered. Inga then shyly asked me to fuck her in her ass using a special strap-on she had had made from the replica of her husband´s cock. But it was an unusual type. It had the same type of bulb on a U-splint as the developed C-string and there were no straps going through the crack of my ass and round my waist.
Inga also pulled forward an advanced fucking bench and entered it after we had had a thorough foreplay on the couch. I entered her ass and soon found out that I too got a lot of joy from the fucking. The bulb in my pussy did wonders. We had a long fuck and in the middle of it Eric appeared in the doorway. Inga couldn´t see him so I beckoned for him to stay silent and watch. Toward the end I showed him what was stuffed into his mother´s ass before silently telling him to move away.
Inga rose from the bench smilingly. She asked if I thought that Eric had rested enough so that we could take the imprint. I answered that I knew he had, saying that he had been watching us and had got a real nice boner.
"Oh, goodness gracious me, he did?" Inga looked bewildered for a little while but then her face cleared. "No harm done, I guess. There wasn´t much that he hasn´t seen before, was it? Well, except for seeing his mother getting fucked in the ass by another woman." She started to giggle. "Well, if he got a hard-on, he must have enjoyed what he saw, don´t you think?" She added, heavily giggling. "Oh my god, what a morning."
She stood for a while calming down.
"Well, let´s go and see if he is willing to pose for getting eternal. Well, part of him anyway." She started to giggle again. It was the first time I had seen her really loosening up, I thought.
Inga marched out of the room. I noticed with pride that she was a bit stiff-legged. She called out loudly for Eric. She had made no attempt to put something on and it seemed that she hadn´t given her nakedness any thought at all. I followed her example and together we found Eric in the kitchen.
He made big eyes when we marched in stark naked. His eyes darted all over us and he had trouble to decide where to look.
"Eric, I want to have a casting of your cock and Miss Barbro has promised to help us making it," Inga said without any preamble.
"A casting? What is that? What for? How should that be made?" Eric asked.
"Well, let me explain," Inga started but then hesitated not knowing how to go on. "Oh, follow me and let me show what I mean," she said. She turned and marched back from where we came from. Eric and I followed her, and I could see that he admired her rolling ass.
She went directly to the chest of drawers and pointed at the imprint of her husband´s cock that still stood on the top.
"See, that is what I want to have from you too. That is your father´s cock. I am sure that yours will be just as great," she said matter-of-factly. There was neither hesitation nor shyness in the way she told what she wanted. "I have the kit handy. We can do it right away while Miss Barbro is here and ready to help."
Eric looked back and forth at his mother, at me and at the imprint of his father´s cock. He swallowed a few times not knowing what to say.
"Uh . . . well . . . what do I have to do?" He finally said.
"Oh, it´s simple really. First you must get erect and that can´t be a problem. We can get naked to help you along . . . oh my goodness, we already are naked. Well, I am sure that Miss Barbro can handle it. Then your cock must be lubricated. The best is to have a woman´s juice all over it. Miss Barbro has promised to provide that. I would love to do it myself but that of course is out of the question. Then we take an imprint in a tube with plastic of some kind. After that we fill the tube with plaster. That´s all. Quite simple and straight-forward, don´t you think."
"Uh, well, I guess so," Eric stammered.
"Great, let´s do it then. Miss Barbro, will you take care of the erection part while I get the tube ready," Inga said, now all business. Well, she had been like that since she went looking for Eric.
I moved close to Eric and pulled his shorts down. I was happy to find a semi hard cock. It didn´t take my mouth long to get him fully hard. I dragged him to the bed and lay down on my back. I pulled him over me, but he needed no more encouragement. After some nice caressing he found his way into my pussy. I was astonished how quickly my body had responded and got ready to accommodate him. He started to fuck me, and I had to hold him back. The purpose of the fuck was just to get his cock well lubricated with my pussy juice.
"Calm down," I told him giggling. "After the imprint is taken you can have me properly. Meanwhile you can think about how you want to fuck me."
Inga came forward to investigate how we were doing.
"I think he is as ready as he will ever be," I told her.
