The Story POV, no dildo please. You are sitting in bed reading when your son enters. You smile and ask how school is going. He tells you that he's got a test on human reproduction tomorrow and he has no idea how it works. You're a bit amused but you want to help, so you try to explain. "Well, when a man and a woman love each other, they... you know, make love, and... make a babee." It's clear he's not getting it. "Maybe it would be easier if I walked you through it." "So first, the man and the woman need to become aroused." Aroused. "Yes, that means they, well, first they kiss." You tenderly kiss him to demonstrate. "Yes, like that. And they touch each other in their special places, to make each other feel good. Where? Well that's different for everyone. For mmomy, I like to have my breasts touched. Would you like to feel?" You pull down your camisole, letting your son see and touch your breasts. You ask him to kiss them, and suck on your nipples - lots of camera focus on them. "Yes, that feels good," you whisper. "And then, the man puts his hand between the woman's legs, and touches her vagina." Your son complies, and your hips rise up to meet his hand. "Yes, it does feel wet, doesn't it? You see, a woman's vagine, her pussy, gets wet when she's aroused. And when a woman is... ovulating, it's much easier for her to get wet." "What's ovulating? We'll get to that." "Now, when a man becomes aroused, his penis will get hard." You smile and reach down, stroking his cock. "Yes, long and hard, just like this. And when the man gets hard, he puts his penis in the woman's pussy. ...How? Well, let me lie back and I'll show you." You lie on your back, cupping your breasts. "See, the woman lies on her back, and then..." You grip his cock, "the man slides his penis in... oh, yes, just like that. Does that feel good? Now, once he's inside, the man starts moving his cock, um penis, in and out. Yes, that's it." You close your eyes and moan, squeezing your breasts as he fucks you. "Do you feel how wet I am? That means Mmomy is very aroused. And - mmm - there's a very good chance, that Mmomy is ovulating." "And Mmomy can feel you, getting harder. And when Mmomy's boy is ready, your penis will start, MM, throbbing, and it'll feel really good. And you'll shoot a special thing called sperm, deep into Mmomy's wet, fertile pussy. Are you feeling yourself getting harder?" He is, and you urge him on to cum, deep inside you. When he does, "YES, that's it, let all your sperm out. Let it all go in Mmomy. Oh GOD, I can feel it squirting out." After, you lie on the bed, fingering yourself, continuing to explain. "That was VERY good son. And now, your sperm will swim up through Mmomy's cervix, and if Mmomy is ovulating, it'll find her egg. And then the sperm and the egg, will join together, and they'll make a babee. Understand?" "Well yes honey, that does mean Mmomy might have your babee. Mmomy's very wet and fertile right now. Aww, don't worry, it's okay babee. Go on and study."
