First time with sister

I carried her down the hall to the bedroom. After laying her on the bed, I started to rip off my clothes. She watched me and reveled in my body. God, she was hot. I wasn't, though. My manhood was elongated but still soft and dangled between my legs.
Grinning like a cat, she took it in her hands when I settled next to her. "I've wanted to try this for a long time. Tell me if I do it wrong." She slid down and dipped her head. After pushing my foreskin back, she licked around the crown. It started to grow. She wanted to feel it grow in her mouth, so she opened wide and dropped her head, sucking me, tasting me, feeling me grow from mostly soft to throbbing hard in her mouth.
I groaned. "Oh, dear sister, that feels wonderful!"
She adored me in her mouth, and loved the taste. She licked and sucked. I took her hand and placed it at the base of my shaft.
My hips rotated slightly pushing my manhood into her mouth and retracting it.
She bobbed her head to the timing of my short thrusts in her mouth. After repeated thrusts she released me from her mouth with a slurp. "Let go in my mouth, I want to feel you come in my mouth."
"Yes!" I gushed. "And then I'll do the same for you. I've been dying to taste you."
"Perfect!" Her head dipped again, and she explored every inch of my shaft with her lips and her tongue and the inside of her mouth. She brought her other hand to my large nuts and fondled them tenderly as she bobbed her head and sucked and licked and jacked on my hard-on.
A few minutes later she felt my manhood suddenly become thicker in her mouth and jerked involuntarily.
"I'm coming, sis! Oh, I'm coming!"
She wanted to see my seed jet out so she pulled back. I groaned, and ratcheted my hips up completely off the bed. The end of my shaft hit her on the nose, and at the same instant, seed flew, splashing over her face. Quickly sucking my shaft back into her mouth, she felt the second spurt hit the back of her throat, and she swallowed, gulped down the seeds. Another surprise! She loved the taste. She swallowed again and again, milking me with her mouth and hand, and all of a sudden I collapsed back to the bed as if all the energy inside me whooshed out. She looked up at me. I lay limply with eyes closed and a small smile on my lips. The juice was still drooling from the end of my shaft, so she licked it off. She felt my outpour across her face where the first spurt had struck her, and with a finger, she wiped it away and sucked the juices into her mouth. She adored the taste! Another lick at the end of my shaft, and she felt it softening in her hand.
Sliding up next to me, she kissed softly. "I love you,brother. I love you so very much." My smile widened and eyes fluttered open. "And if you don't do the same for me right now, I'm going to scream," she added.
I laughed and rolled her to her back, and pulled the hem of her skirt above the waist, to reveal no panties and the most beautiful sight, mound waxed to the skin and bald as a baby's behind.I was shocked! I stared at her beautiful bald mound. God she had her private waxed. So adorable, so inviting. Sliding down, I settled between her legs, long legs dangling off the end of the bed. I pushed her knees up, and my hands caressed the inside of her thighs. "Has anyone ever tasted you before?"
"No, I've done a little petting, that's all. I never wanted anyone but you. Do it, brother, damn it!"
Her loud sigh of pleasure stretched out as my mouth covered her opening and tongue rasped up through her crease. As my tongue rolled and played over her sweet spot, she climaxed. She didn't know an orgasm would happen. It overwhelmed her all at once, swooping like a roller coaster moving at full speed and hitting the bottom of a dip, only to be taken aloft again. She opened her mouth to scream, but no sound exited. Her eyes snapped wide, but they couldn't focus. Without realizing what she was doing, she grabbed the back of my head with her hands and jerked me forcefully to her mature mound and at the same time, clamped her thighs tightly against my ears. Her entire body stiffened, rising from the bed. The orgasm continued, becoming stronger with each passing second. No sounds escaped her lips. She didn't breathe or move.
Finally, the orgasm released her, She relaxed her grip on me, and I jerked my head to the side so I could breathe, but she grabbed my head again when another contraction hit her, and a second later another struck - and another and she jerked with each assault, whimpering between the pulsations. I didn't know if my sister was aware that pleasure of such magnitude could exist. At last, she calmed with only soft pulsations striking her, each of them softer and farther apart. She collapsed.Tears of pleasure streamed from her eyes. She pulled me up so she could kiss me.
When she could, she mashed her lips to mine and moaned. "My God, what did you do to me?" she asked.
I laughed. "I licked you for the first time. It was your first orgasm. I've never seen anything like it. I take it you like my mouth on you."
"You can taste me anytime you want, bro. Anytime. I'd never let your face from between my legs."
I laughed, and she felt my erection pushing at her divine opening.
"Are you hard again?Wanna push it in me?" she asked with a mischievous grin.
"Well, go ahead then."
I did!!
