Not everyone is as fortunate or as knowledgeable as you, the reader. Here is an example of a less fortunate couple as they learn from one another.
Carol has played with her clit before. She knows the feeling of tension building within her, from her thoughts and her self-fingering. She knows the feeling of relief when her back arches, her system explodes, her juices run free, and her fanny collapses onto her bed..
She can feel the same tensions building within her as she allows twenty-year-old Josh's hands to explore her breasts. Here she is; nineteen years old, working full-time and allowing a boy to fondle her for the first time. She smiles inwardly.
No one had asked her to the senior prom. She had to ask her drunken father to take her that evening. Her academic skills, her plain looks; her plain clothing; her mother's restrictions, the bruises on her arms caused by her father's drunkenness; all contributed to her being ostracized from the social life of school.
Now she is no longer in school. Now she is working for a living. Now, she buys her own clothes. She no longer has to tolerate her father's drunkenness. He is in jail awaiting trial for spousal abuse.
Mother is no longer afraid to stay home alone with father. Mother eliminated her restrictions on Carol. "You're over eighteen. I'm done supporting you and your drunken father. Find yourself a man to support you. Go out and be a whore if you want."
Now Carol is alone with Josh; her co-worker; in a parked car; in her mother's driveway. As they kiss, Josh's hands explore her breasts and his tongue explores her mouth.
She's thinking, "He's trying to undo my bra. I'll help him."
The bra is now loose. "You're so beautiful, Carol," he says as he peeks at her bare tits. His thumb flicks a nipple. He starts to squeeze her tit as if he is trying to milk her.
"Not too tight, Josh, please."
He releases her tit and his hand wanders down to her belly button. A finger explores the depression. The tension inside her is building up. She says nothing as his hand presses her flat stomach and discovers her pubic hair. He tousles her bush and discovers her slit; she kisses him harder. He takes the hint and finds her clit. It is hard and easy to find.
"He's good with his fingers. He's going to try to get inside me. Should I let him? Oh, fuck. Why not?"
While she's thinking about it, his fingers discover her vaginal opening and penetrate it; first one finger; then a second finger. There's no room for a third finger, not this time. His thumb goes back to manipulating her clit.
She breads away from the kiss only to breathe an "Aaahh." Then she goes back to her passionate kiss.
His thumb flicks her clit left and right; back and forth. His fingers tickle her inside while they move in and out.
A thought flashes through her passion. "I'm getting finger fucked for the first time in my life. How nice it is." Then her passions resume control of her thoughts.
Her hand drops from his shoulder to his crotch. "He has a big something in his pocket. No, it's his dick. He has a hard-on for me. No one has ever had a hard-on for me. He knows I feel it. He's letting me feel it."
