Sex Education for Her Daughter

A friend of mine was sent on deployment and asked me to take care of his girlfriend. So every night I could I would go over and have dinner with her and her daughter and we became good friends. One night after she had taken a shower I came by and while she was sitting on the sofa in her robe we started talking about anatomy measurements. She wants to know if the leg is the same length as the arm so we get out a tape measure and she opens her robe so I can measure her from her crotch to her foot then we measure from the arm to the finger. It does not correlate so I suggest that it might be different on a man and take my pants off so she can measure me. I am not wearing underwear, so as she is fiddling with the tape measure my cock starts to get hard. She moves it to the side so she can measure my leg and gives it a little kiss. This gets it even harder. I stay with my paints off, and she does not close her robe. We sit on the couch and continue talking with my cock sticking straight up and demanding attention. She tell me she once hear that you can tell the size of a man's hard dick by the length of his hands so she measures my hand and while she is measuring my cock she gives it another kiss on the tip. I tell her about how I love to masturbate and about some of the masturbation adventures I have, she starts to get horny when I tell her about watching others have sex and she starts playing with her pussy.

I start caressing her breasts and before long we are screwing our asses off on the living room couch. After I came we go to her bedroom and I start eating out her pussy on her king-size waterbed. I get my cock hard again and start finding the right wave rhythm for our fucking on the waterbed. I cum again and we both go to sleep. When I wake up in the morning I hear her talking to her daughter. I am naked spread eagle on the bed and she and the daughter are sitting on the edge of the bed. She is giving her daughter a sex education lesson, and using my cock as a prop. She strokes it and gets it nice and hard and then explains how men like oral sex. Her daughter just watches as she goes down and starts to give me head. She stops and is just stroking my cock while she talks about the testicles and scrodum. I open my legs a little wider and raise my knees and she points out my anus and tells how it is sensitive to men and how to caress it. She licks her finger and using the spit starts to rub my ass hole while at the same time stroking my cock. It feels so good I just relax and let her do anything she wants. While explaining what she is doing she starts to insert slowly her finger into my anus, it is a little dry and my cock is needing lube too, so she tell her daughter to go get the hand cream from the bathroom. When she returns she a takes up a better sitting position between my legs as her mother puts cream on her finger and hand. The finger is inserted into my ass and the hand is griping my cock. She explains how the prostate gland is stimulated by her finger and to watch the effect upon me when she stimulates it. I roll my eyes back into my head and moan ecstatically. Then she increased her stroking on my cock and the massaging on my prostate through my ass, oh it feels so very good. She talks about where the sensitive areas are on the cock and how to caress them. While she is pumping her finger in and out of my asshole she asks me to show them how I masturbate. I grab my nicely lubricated cock and start stroking my cock in the same rhythm as she is using in going in and out of my asshole. I ask her if she wants to let her daughter jack me off and she says no she is just there to watch. I let her take over stroking me so I can play with my nipples and she pumps me to a fantastic orgasm which spirts all over the place on every body because as I start to cum she starts shaking my cock and it gets quite messy. I ask her if she wants me to eat her pussy out and teach her daughter about that, she says no need as she and a girlfriend had already taken care of that and together and taught her daughter all about pussy eating. But she would never the less want me to eat her pussy, and she does not mind if her daughter watches. So I position myself between her legs and start eating her pussy. I am on all fours and my ass is in the air pointing towards the daughter so she has an unobstructed view of my asshole and cock. I start stroking my limp dick and as it is still very nicely lubricated from earlier it get hard again within five minutes. I am really getting into stroking my cock and licking the clit when I feel something touch my asshole for just a second. I lift my ass higher into the air and spread my legs open a little wider and then moan. Soon I feel again the touch, the probing and the finger exploring my sphincter I relax and contract my anus alternatively and hear a giggle among her mothers moans. The finger now starts to push it's way inside and feel around I moan which caused her mother to moan and the daughter giggle. I feel another finger press on my balls and then touch them and roll them around in the scrotum. I stop stroking my cock and focus all my attention on the pussy I am eating. I feel the finger leave my ass and two hands start to milk my cock in a downward motion. I moan, she moans, giggle. We keep this up until my pussy licking pays off and she has an orgasm. The hands move away from my cock and so I move up and slide my throbbing cock into the swollen pussy and it does not take too long to cum. When I get up and turn around and the daughter is gone. We go in and have some orange juice and can hear the daughter moaning and then cumming in her bedroom. She tells me that Clay would never helped teach her daughter about sex like I had, and she knew I Would because of my telling her last night about all the masturbation I did, and how I had done it in front of others. She asks me to promise not to have sex with her daughter and I agree. Soon Clay returned and they were a couple again, we never told him about our affair. I stayed with the daughter on a couple of occasions, and once they left for the evening I would strip down and masturbate all evening long, the daughter would sometimes come in and we would talk and sometimes she would also masturbate. I showed her some other techniques I used, and she let me borrow the vibrator her mother had bought her for me to play with my anus with. We never had sex, just watched each other enjoy ourselves.
