After playing with herself for a while Cassie looked up deep into my eyes and said, "come here sweetie."
I took off my shirt and leaned in with my stiff cock sticking out proudly. Cassie unclipped her bra and threw it on the floor, then put her hands on my hips, sliding them around onto my ass as I got closer. She slowly helped guide me inside of her, looking at me with that innocent look biting her lip. She gasped as I slid the top of my hard cock inside her pussy. I slid myself back and forward gently until I could push the whole way in. Cassie moaned deeply in appreciation.
This was everything I'd been waiting for and oh god did it feel amazing inside her warm vagina. I started pumping at a steady pace, wanting this to last as long as it possibly could.
"Ohhhh sweetie that feels sooooo nice," she said.
I loved that she was still calling me sweetie at this moment, her one and only little pet name for me. With this gentle sensual feeling that was happening between us, I decided to step it up a notch so that she knew I could fuck her hard when she needed it.
"I'm glad it feels good for you, feels amazing for me too. Mmm getting to fuck my sexy sister, never thought this day would come!"
It seemed she liked the idea that I reminded her we were siblings, and locked her lips against mine for a nice long wet kiss. While we licked each other's tongues I started pumping my cock faster inside of her and then thrusting harder. She let out a shriek muffled by my mouth stuck to hers. I kept kissing her and driving it in harder still. It was too much to hold back so she pulled her mouth away and let out a squeal followed by a long deep moan.
I kept on fucking her hard but not too fast, letting up momentarily just so I could shock her by ramming my cock in deep again. Each time I did she let out a sexy deep moan.
I started pumping quickly again and as I was not letting up now she started gasping loudly.
"Ahh, ahhh, ahh, ahhhhh!"
She rocked and twisted her body in pleasurable pain as I joined in with her sounds, not letting up on driving her as hard as I could. I had dreamt of this moment for so long and I was determined to give her the fucking of her life. Hopefully that meant she would want me again, and if not, she would always remember how passionately I showed my love for her this one incredible time.
As she started to shake, her body came up off the lounge, I slowed down a bit to a more steady pace but kept thrusting.
"I'm about to come sweetie! ohhhhhhhh!"
I felt myself tingling at this point and pumped her quickly to reach climax at the same time. I came inside her letting out a deep moan, and Cassie made all kinds of sexy noises as she rode the ecstatic feeling of her orgasm. I held onto her hips as she writhed up and down like she was possessed. I had never seen anything like it, I guess I'd never managed to pleasure a girl that way before! Or maybe it was just that Cassie was more in touch with her own pleasurable feelings than any girl I'd previously been with.
What a sexy little angel she was. I held her until she calmed down, gently letting her body fall back into the lounge and letting out a final, "ohhhhhhhhhhhh."
"Ohh, my, god!" she said breathing heavily, "holy fucking shit Grant!"
I was speechless for a moment, my whole body was tingling and I was completely exhausted.
"Ohhh fuccckk! that was fucking amazing sweetie! I had no idea you were going to make me feel like that!"
We both giggled, "I'm so glad it felt good for you," I said.
"Ohh fuck that is a fucking understatement if ever I heard one! I have never, ever, felt like that before. No guy has ever made me orgasm like that. You really know how to make a girl feel wonderful."
I was so happy that she approved of my performance, indeed loved every moment of it according to her raving review! I was in heaven the entire time of course, feeling extremely excited and satisfied at every little moment. I will never forget that night as long as I live.
We laid with each other naked for a while, kissing some more and giggling about nothing. Then we chatted and had a couple of drinks before taking ourselves off to our respective bedrooms, both completely exhausted.
I was woken early to the sound of the shower which was close to my room. Immediately I remembered the visions of the previous night, watching Cassie slather up her wet naked body with no inhibitions. I felt like going and letting myself in the bathroom for another show, but decided that might be a bit too presumptuous.
So I lay in bed dreaming about how truly wonderful the night before had been. I'd lived the fantasy that I had dreamt about in detail for months, and to some extent years before that. I heard the shower stop after a little while and about five minutes later there was a knock on my door.
