My Japanese Mother and Me #4

My Mother and I talked a lot over the next few days about our relationship. She reminded me again and again that our special relationship must change as I get older. She explained that being attracted to young girls was normal, but kept reminding me that too much worrying about girls and thinking about sex would have a bad impact on my studies.  "Holiday time is OK but you must avoid getting involved with girls at the university," she insisted. However, she was realistic and determined to manage the situation so she invited the family we had met at the onsen to our home for lunch. Knowing the father would be at work but the mother and daughters (Kazuko and Yoko) would be home for the holidays, she made it mid-week. The sushi was delicious and portable so she suggested we take ours out to the courtyard so our mothers could have a nice chat. Once outside, the girls and I relaxed and chatted about the latest J-pop songs and singers. They soon shifted the conversation to our meeting at the onsen. "You seemed a bit shy," Kazuko the older one suggested sympathetically, adding, “We go every month so we are used to it.” "Yes," I confessed. "I had not been like that for years". "Some of the boys play with us," explained Yoko the younger one. "It is not fair if they stay in". "She means because they can see all of us but we cannot see all of them," her sister explained. "Oh! Yes, I agree, it is not fair," I acknowledged. "Show me yours then Yoshi," demanded Yoko. "You mean now?" I blurted. "Why not?" they chorused. Realizing I was probably sounding very un-cool, I looked back at the house. "OK but you must promise not to tell". "I promise," they chorused, so I unzipped and pulled out my dick, relieved to see it had shed its wrinkles and grown to a respectable size. The looked in silence for what seemed like ages. "Mummy says they get stiff if you touch them. Can I?" asked Yoko, and without waiting for an answer took it in her soft warm hand. "Wow! Kazuko, I can feel it getting bigger, getting stiff. Just like Mummy said," she confirmed, and looking up at me with a huge grin asked, "why does it get stiff?" "So it can go inside a vagina," her older sister commented casually. "Has it yet?" "No. Definitely not," I assured, blushing and forcing my now fully erect penis back through the fierce teeth of the zipper. After they left, I told Mum what had happened. She was very relaxed about it, and did not even care if they told their mother, who was apparently a very sensible high school teacher. She would be back at work next week but Monday was a student free day so my Mother had suggested that the girls spend the day with us. Their mother had readily agreed. The girls were dropped off by their mother on her way to school with last minute instructions to be good, and be sure to take a bath. The significance of her instructions was lost on me at that moment but after lunch, when Mum sent us all to have a bath, I suddenly realised that the mothers had arranged it. Both mothers wanted more innocent boy/girl explorations in a safe environment. We certainly gave them plenty of explorations over the next couple of hours and Mum would look in on us occasionally to keep it safe. In the beginning Kazuko was a bit reluctant to touch or be touched but to her younger sister Yoko this was a unique situation and she could not get enough. Yoko was fascinated by my erection and, while I was giving her a back massage, she kept turning on the stool and touching it. Mum knocked and came in with towels for the girls. She noticed my erection and smiled knowingly but made no comment as she left closing the door behind her.  "If you keep doing that he will ejaculate,” warned Kazuko, knowledgeably. "Really! Oh, please ejaculate for me Yoshi," she pleaded and sure enough I started spurting and she started squealing with delight.  "Look there is semen going in my vagina," she claimed, sitting back and spreading her labia to invite more in. It was a lovely sight. I lay back on the mat, enjoying just how lucky I was to have a wonderful Mother, who had put me in this extraordinary learning situation.  "Smells funny," Yoko observed, looking closely at the semen on her fingers. "Can I taste it?" "If you want." "Tastes funny too," said Yoko, licking her fingers. "Some girls really like the taste. They even suck their boyfriend’s thing. When he ejaculates they drink his semen."  "Have you?" "I do not have a boyfriend" Kazuko snapped defensively. "I want to try Yoko," insisted, and squatting over my chest bent and bit my penis. My pain was short lived but I overreacted, seeking sympathy. "Not like that," cautioned Kazuko and, in an effort to assert her seniority and demonstrate her wisdom, she knelt and took my still flaccid penis in her mouth to demonstrate fellatio to her little sister. She licked and sucked skillfully, perhaps not for the first time, so it did not stay flaccid for long. Yoko stayed squatting over my chest and even moved back to gain a better view. I eased her up until my tongue found her vulva, where I tasted her and myself as I licked and sucked. My earlier climax allowed me to hold back for quite a while and enjoy Kazuko’s gentle attention. Very slowly I slid my hand down her thigh to her knee, then up again on the inside. Her thighs parted a little and tenderly I explored their union. I found her clitoris and stroked it gently. Her thighs parted a little more but other prizes were out of reach. I wanted this to go on forever, but then Yoko started wriggling her vulva against my lips and pressing down hard and my tongue went inside a tight little ring. Everything felt so wonderful I knew that I would climax soon. I warned Kazuko but, she kept my penis in her mouth while I came.  “Did not spill a drop,” Kazuko boasted. Her audience had been too busy to notice. Eventually, I recovered enough to ask Yoko if she had climaxed, as the flush on her chest suggested, but she was too overwhelmed to reply. Yoko just watched in silence as her big sister let me reach those places that had previously been out of reach and even took the initiative to show me how she gave herself a climax. It was sensational to kneel beside this beautiful girl when she did that but I was disappointed that she just did it on the outside. Afterwards, Kazuko became very compliant and let me have a really good look at her hymen and use my tongue to feel its tight ring. We rinsed and were all in the bath when Mum knocked and came in with cool drinks. She reminded us that the girls’ mother would be here soon to pick them up and left us to enjoy our propinquity for a few minutes more. What a wonderful lady!
