Mother peeled my wet messy panties down my legs and took them off me.  “Now, lets get you cleaned up and into a fresh clean pair of mother’s panties.  Son, I just love hot sexy and you looked in my panties.  It’s made me feel warm all over and my vagina lips are swollen?”  “What does that mean, that your lips are swollen.  They don’t look swollen to me”  She goggled and said ” I have so much to show you and teach about women.  The lips I’m referring to are called labia and they swell and get warm and hot when I get sexually excited like I am now.  I think that’s it’s time that you no more about this and you’re not going to learn it from books or your friends at school.  Come over here and and sit on the bed with me.”
She pulled her white full nylon slip up so she could slide on the bed and I got a view of her stocking tops and the white straps of her garter belt.  I was starting to get hard again in my pantys.
Mother scooted on the bed so that she was sitting up with her back against the head board.  She patted the bed next to her indicating that I should sit next to her.  I crawled on the bed and sat in front of her waiting to see what she would do next.  “Ok, son, now I’m going to show the very special parts of a woman’s body and there are many.  I want you to pay special close attention to todays lesson.  There will be many more and they all build on each other.  I want you to learn you lessons well so that you will please and pleasure your mother exactly the way I want it.  some it’s time for your very first lesson and since we just talked about mother labia that would be a good place to begin.”
Mother knows just how much you love my panties and now I now just how much like wearing them but right now we are going to do something different.  Now I want to sit right there and mother is going to pull up her slip, slowly, because I want to see your reaction to what I’m about to show you.”  Her slip rose higher until I saw the tops of her stockings and the white straps of her garter belt tabs.  Her skin just above the stockings looked smooth and silky and I wanted to touch it.  The she slowly began to pull her knees up toward her chest and began spreading her legs slowly. “Now sweetie” she asked “can you see mother panties yet?”  I looked between her legs and blushed andturned my head away out of embarrassment .  “Honey, look at me now.  Look at mothers panties.  I know you want to and I know how sexy they look to you.  I know because I see that your excited again.  You look so hot with your cock getting hard like that and in my panties too.  Keep you eyes on my panty gusset.  I’m going to spread my legs wider so that you can see everything really well.  what do you think?” she asked as she spread her legs for me.  Her white nylon panty crotch was wide and I could see some dark hairs sticking out of the leg opening.  I leaned in to get a better look but though that she might not like that.  I stopped.  “Sweetie? why don’t you come closer to mother so you can get a really good look”  I did.  My faces was inches from her panty crotch and I could feel the warmth of it.  As I was taking a good long look I noticed a tiny wet spot that I hadn’t seen before.  I watched as it got bigger and more transparent.  I began to smell something now.  It was unusual but it made me feel warm and excited.
“Come closer son, I want you to touch and rub the crotch of my panties very softly and gently”  I reached out my hand to touch her and I felt the heat coming from behind her panty gusset.  I touch her wet spot very gently and heard mother let out a soft little moan”  That’s a special place your touching.  It’s called a clitoris and it’s full of sexy nerve endings that feel really good when they are rubbed and touched.  Go ahead rub me a little more there.”  My cock was so hard in my mother panties.  I couldn’t believe I was dong this.  I had thought about what my mother would  like in her panties and now I was seeing for myself.
