She lets a low moan escape when he leans forward and takes a nipple into his mouth. Her first instinct is to push his mouth off of her nipple, but he refuses to surrender that nipple and sucks harder. Her breathing picks up, and instead of forcing him off of her breasts, she pulls him closer to her bosom. Logan becomes braver and carefully slips his hand inside her navy-blue panties. She spreads her thighs and welcomes his exploration. After a few minutes of enthusiastically devouring her nipples and fingering her pussy; she starts to hyperventilate and then tremble. A minute later, his Sister stiffens as her orgasm engulfed her whole body.
She squeals and then places a palm on each side of Logan’s face and pulls him to her lips. He can feel her tongue anxiously poking at his lips, trying to gain entry to his mouth. He lets her in, and their tongues dance and twist causing both their heads to spin. He had no idea his sister could kiss like that. It is the most thrilling, most passionate kiss he’d ever experienced. That includes the kiss from Mom. He doesn’t know how long that kiss lasted before she breaks away and says, “Oh my God, where did you learn how to do that?”
He assumes she’s talking about sucking her tit until she orgasmed and without thinking, he said, “Mom taught me.”
“What the hell do you mean, Mom taught you?”
“I’m sorry, Becky, but I promised Mom I would never reveal any of the details of our sexual endeavors.”
“Too late, Logan. You opened this can of worms. Now tell me everything that is going on with you and Mom. I want to hear all about your incestuous affair with our sweet Mom,” she demands. “By the way, you do know it’s incest when you have sex with a blood relative; don’t you?”
“Yes, I know it’s incest when I have sex with Mom.”
“That means you can’t use the incest excuse as the reason we can’t have sex with each other.
Becky’s eyes actively scan her brother’s face waiting for his response. He doesn’t know how to answer. He just sits there with a dumb expression on his face. Becky is quiet for a considerably long period. Logan can see the wheels turning in her mind. It is apparent she has many more questions rumbling through her head. He is getting turned on just thinking about the information he had learned from his Mom about how to please a woman. His cock is threatening to pop out of his boxers.
Becky finally breaks her silence when she says, “You say Mom taught you how to cause a woman to orgasm with your tongue on her tits?”
“Absolutely! She taught me things about using my tongue on a woman in ways I never dreamed about.”
“Did she teach you to use your tongue anyplace else on a woman’s body to make her orgasm?”
“As a matter of fact, she did. Why do you ask?”
“Well…I hear girls at school talking about…” Becky blushes and looks away from him. He can tell she is struggling inside with what she wants to ask him. He lets her stew for a moment and then motions with his hand for her to continue.
“They say that it feels terrific when a guy licks you down there,” She blurts and then looks away. Her cheeks are bright red, and her breathing has increased considerably. Even though they had always been able to talk to each other about almost anything, he knows it took a lot for her to say that to him.
“And let me guess,” he grins. “You would like to find out firsthand what it actually feels like, but are too embarrassed to ask me to show you.”
Becky stares at the floor and shakes her head yes. Logan tries not to act too enthusiastic about her request. He has wanted to taste her pussy almost as much as he’d wanted to play with her tits. He gives her a loving squeeze and asks her to slip her panties off and lay back on the bed. She quickly flops onto her back, raises her hips, and slides her panties off in one smooth, swift motion. Logan crawls between her splayed legs and kisses her inner thigh. He plants a series of gentle little kisses to each thigh as he makes his way up to the promised land. He takes in a deep breath inhaling her feminine aroma while using his thumbs to fold back her labia. After a few puffs of warm breath in that area, her clit pokes its head out of its hood. Just as he moves in to make contact, Becky put her palm on his forehead and says, “Your tongue only, Logan; I’m not quite ready for you to stick your cock in there!”
“I promise, Sis. I would never do that unless I had your permission.”
She removes her hand from his forehead and says, “Okay, but promise me it will be just your tongue until I say differently.”
Logan assures her he wouldn’t violate her trust and begins his approach again. He spread the lips of her vagina and again blows gently on her opening. He had learned that technique from a porn site, and his Mom had loved it when he did it with her. Just like with Mom, Becky’s clit pushes out from under its protective hood. He returns to kissing and licking her inner thighs while listening to her moans and gasps. He moves back to her pussy where he runs his tongue over her wet labia. Becky lets out a deep guttural groan, and then he feels her hand on the back of his head; guiding him, just like Mom did, to the places she needed him. He begins licking her hot folds, listening to her moans of pleasure as he continues running his tongue up and down her pussy lips. He parts her folds with his tongue and lets her juices flow.
Logan works his tongue deep into her pussy before moving up and taking her clit into his mouth. As he begins sucking his Sister’s clit, he works a couple of fingers deep into her pussy. He alternates between licking and sucking her clit, and she becomes more and more excited. It isn’t long before she is thrusting her pussy hard into his face as the next orgasm washes over her.
Once she comes down from that orgasm, he proceeds to lick on and try things that had pleased Mom. He brings Becky to the edge of her next orgasm and then shoves his finger into her anus just as she explodes with orgasmic bliss. She successfully stifles a scream. He can feel the lust and pure enthusiasm coming from her as he sucks her clit between his lips and gently flicks it with his tongue. Every once in a while, she stiffens and uses her hand to push him deeper into her silky tunnel. After a while, she can take no more and pushes him off of her sensitive vagina.
They hold each other close for a while. It is getting near midnight, and both are nearing exhaustion. Logan’s jaws are aching, and his tongue is on its last lick. He leans over and kisses Becky on her lips and lifts himself to get out of her bed.
She places her hand on his arm and asks, “Where are you going?”
“I’m going to my room. We sure don’t want to fall asleep and let Mom catch us in bed together.”
“Don’t go just yet.” She hesitates a moment and then says, “I want to make you cum before you leave.”
“But I thought you said you were not going to let me fuck you?”
“I’m NOT going to fuck you right now. I just want to suck your cock. You made me cum at least five times tonight, and the least I can do is suck your cock until you cum at least one time.”
