After watching their parents have sex, Holly and Thomas had lots of questions. A Saturday afternoon in the family's living room provides some answers.

Over the next few days, both Thomas and Holly started asking me and Sue lots questions about what they'd witnessed on Saturday evening. After a discussion, my wife and I agreed that rather than deal with their questions individually, it would be better to note them down, and answer them all together. That way, both Tom and Holly would receive the same answers.

On Saturday afternoon, we all got together in the living room. Sue had made a list of all Tom and Holly's questions in readiness. We seated the children on the sofa and prepared to begin. Sue read the first question from the list.

"How often do you and Sue practise making babies? That one was from you, wasn't it, Thomas?" Tom nodded.

"Well," said Sue, "we usually do it several times a week. But if either of us is too tired or not feeling very well, we won't normally do it. Does that answer your question, Tom?" Tom confirmed that it did.

"Next," said Sue, "Holly wants to know how big do willies grow. Duncan do you want to answer that?"

"Well, Holly", I said, "Willies come in lots of different sizes. Some are a bit smaller than mine, others are a bit bigger. It doesn't really matter, they all do the same thing."

"Thank you" said the 7 year old.

Sue read the next question. "Holly wants to know how big Thomas' willy is. Tom would you mind showing your penis to Holy?" Thomas glanced at me nervously, looking for a cue as to what he should do.

"It's OK, show it to her if you want to" I said reassuringly. Tom stood up and slowly pulled down his football shorts, letting them fall around his ankles. Then he turned to face his stepsister, and pulled his red underpants down as far as his lower thighs and stood still in front of her, holding up his shirt. After just a few seconds, he let go of his shirt and pulled his pants back up.

"That was a bit quick." Sue said. "Let Holly have a proper look" She went over and knelt down in front of my son. My wife helped him to remove his shoes, socks and shorts, then she pulled his pants down, steadying him, as he stepped out of them. Tom's football shirt was going to be in the way, so Sue asked him to raise his arms so she could pull it off him. Now he was completely naked.

Although I had seen my son undressed on many occasions over the years, it was strange to see him nude in the present circumstances. Sue got Thomas to stand side on to me and brought Holly round to kneel in front of him. Holly's face was almost level with the 9 year old's penis.

"Shall we measure it, Holly?" her mum asked her.

"Yes" replied the little girl. Sue had brought in a plastic ruler in readiness and getting it, she knelt down next to her daughter.

"Would you like to hold it?" she asked. The child nodded. We both watched Holly took her right index finger and tentatively pushed the little sausage-like thing in front of her, making it wiggle. She giggled and pushed it again. Gradually gaining confidence, the little girl used her thumb and index finger to hold it, shaking it gently from side to side and up and down. Every so often, she would look at her mum for approval. Although only 9, the sensation of having his penis played with had given Tom an erection.. His uncircumcised prick was sticking up almost vertically.

"Look, Holly." said her mum, You've made Thomas' willy grow." Holly had made MY 'willy' grow too.

"Shall we measure it now?" Sue asked her daughter. Holly nodded and held Tom's stiff little prick while her mum placed the ruler along its upper side.

"Can you read the length off, Holly?" her mum asked. Peering closely at the markings where the ruler met the very tip of the penis, Holly declared that it measured 9 cm long.

"Did you like touching Thomas' willy, Holly?" her mum asked.

"Yeah!, it was all wiggly and funny" she said , giggling.

"Then it was a 'wiggly willy' then, wasn't it" her mum said laughing. Holly broke out in more giggles.

"Thomas, did you like Holly touching your penis?"

"Yes. It felt nice." he replied. Sue told Tom that if he wanted, he could leave his pants off so Holly could play with it again later. He readily agreed.

Sue picked up the list of questions and continued reading.

"This is Thomas' question. He wants to know the different names for the penis and the vagina." Sue got a piece of paper and a couple of pencils and laid them on the table by the children.

"Let's see which names you both know first, then we'll help with some others." Sue told them. Thomas did the writing, as the kids whispered to one another, Holly letting out little giggling noises every so often.

"Right," said Sue, "We'd like you Tom, to read the names for the female bits and you Holly, to read the names for the male bits." Holly went first.

"Willy.... penis... winkle..... cock... dick..... prick" she said.

"OK, your turn Thomas.", I said.

"Diddle.... hole..... and vagina." he replied.

"Now", said Sue, "Vagina refers to the inside passage only. The whole outside area, including the part a woman wees from, is called her 'vulva'. There are lots of other names for the actual vagina, but the most common ones are pussy......and cunt."

"Pussy?" Holly repeated, giggling, "Like a pussy cat?"

"Yes, the same as a cat." her mum replied. "Cunt is a bit rude, so don't use it outside the house please." I added.

"Holly, you had lots of good words, didn't you?" I said. "Which one's your favourite?"

The little girl looked at the list for a moment, then said, "Willy".

"Other names for a man's penis include his chopper, his snake.... and his sausage." I told the children.

"Sausage?" said Holly, looking puzzled. Sue broke in.

"Duncan has a large sausage and Thomas has a small sausage.", she said, giggling. Holy turned to look down at Tom's penis to see if it really DID look like a sausage that she might have for her dinner.

"Oooh, it's gone all small again, mum" Holly said, disappointedly. Sue explained that it had only grown bigger before, because Holly had been touching it.

"Shall I touch it again?" the child asked.

"You'll have to ask Thomas if he minds" her mum told her "Tom?", asked Holly, Can I touch your sausage please?" Tom said that she could, and Sue and I watched as the little girl wiggled her little playmate's penis for the second time in 15 minutes.

Sue whispered to me that she may as well show her daughter the correct way to masturbate a penis while she was at it. She got Holly to kneel in font of Tom., before knelling behind her daughter. I watched transfixed as Sue placed the little girl's thumb, index and middle fingers around the thin shaft of Tom's penis. Next, my wife laid her thumb and fingers gently on top of Holly's, and slowly the pair began a gentle up and down motion. Sue gently pulled Tom's foreskin back to reveal the head of his penis, drawing Holly's attention to the tiny hole in the tip. She explained that that was where Tom's wee wee came out from and where his sperm would come out when he was a bit older.

"Errrrhh...it's all wet!" cried Holly, pulling her hand away. With all that rubbing, Tom's little penis had discharged a small amount of pre cum and made the end of his foreskin sticky. Sue explained to Holly that it was quite natural for a penis to get wet when it was rubbed and it showed that Holly had done it very well. That seemed to please her and she immediately took hold of Tom's prick once again, continuing to rub it, this time without her mum's assistance. While she did so, Sue explained about Tom's other bits.

"These are his testicles", Sue explained, "They're often called 'balls'. It's where all Tom's sperm live. If you touch a boys or a mans balls, you must be very very gentle because they're very sensitive."

"Will I make the sperms come out?" asked Holly, removing her hand quickly.

"No, I don't think so", Sue said, laughing at her daughter's grammatical error. "When Tom's a bit older maybe."

My wife then read out the final question for that day. It was a question that I had prompted Thomas to ask.

"Is Holly's vagina the same as her mum's?"

"I think the best way to answer that one is to show you, Thomas" Sue said "Holly, can you get undressed so I can show Thomas your holes?"

"Yes mum" replied the little angel. Holly stood up and raised her arms to allow her mum to pull her turquoise T shirt up and over her head. Next, the little girl undid her short blue denim skirt and let it fall to the floor. Finally, she pulled down her 'Little Mermaid' lilac knickers. Holding on to the arm of the sofa for support, she stepped out of them, picked them up and handed them to her mum.

Sue told her to sit on the sofa again with her legs up and thighs apart. Then she asked Thomas to kneel in front of his stepsister. "Now, Thomas, how many holes do you think Holly has?" she asked him.

"One, I think" said Tom a little hesitantly.

"Actually, she's got 3 holes."

"Three?" repeated Tom, "Where?"

"Holly, point to the hole where your wee wee comes out" her mum told her. Holly placed her right index finger on the opening to her urethra. Tom moved his face closer to Holly's genitals in order to examine the little opening more closely.

"It's so tiny", he remarked.

"It's only designed for her wee wee." I said "Hole number two is her vagina. Point to your diddle please, Holly.", said her mum. Obediently, the 7 year old touched the entrance to her little cunt.

"That's the hole a man will want to put his penis in, when Holly's older and also where her babies will be born from.", Sue explained. Then she asked her daughter to stand up and turn around.

"Put your hands on Holly's bum and gently pull her cheeks apart." she said. Tom did as she asked. Can you see her third hole? It's where her poo comes out" Sue said. Tom found her little anus and looked at it closely, comparing it in his head to his own.

"All little girls are born with those three holes and those holes grow bigger as the girl grows up into a woman." Sue explained.

"OK", said Sue, playfully slapping Holly's bare bottom.

"I think that's enough questions and answers for today. Get yourselves dressed and you can watch TV until dinnertime." With the youngsters occupied, Sue and I went upstairs for some private baby making practise. I told her that there was something about seeing the kids playing sexually that turned me on. Sue told me that it had had the same effect on her. We decided that we would try and make the children part of our sex life more regularly.
