We had discussed this for ages, finally it was going to happen.
I couldn't contain my excitement, my heart was racing as I got nearer and nearer, my cock throbbing with excitement. I have been waiting for this for a while, we talked about it lots of times. We have been masturbating together for years but never quite to this level.
My heart was racing as I opened the front door, my cock itching for stimulation. There she was on the living room floor, her gorgeous trimmed pussy staring at me, her fingers going to work as she lay on the rug. She had been at it for a while, I could tell by her moans and the wetness of her fanny. She was rubbing her swollen clit with her two middle fingers, really going at it like it was her last ever wank. Her right hand working itself deep inside her pussy.
'Hurry Up', she moaned.
My pants were off in seconds, wow I was hard. I was stroking hard as I watched her working her fanny, squeezing her nipples. Every thrust of her fingers inside her lovely pussy being met with every tug on my cock. I was so excited, there was no way I could hold this for long.
'Kneel next to me', she said breathlessly.
I was down on my knees in seconds, kneeling by her head. She was fingering her pussy with her left hand while stroking my soon to explode dick with her right hand. Her moans of pleasure intensified as she squirmed with pleasure, her fanny now taking a nine inch dildo as she tugged on my cock and squeezed my balls. Every stroke she gave me I matched it with a thrust of the dildo. I could not hold on any longer.
My cock exploded it's juice all over her face, her mouth open ready for as much as she could get in. Her fanny wetter than it ever had been before, she lay there taking in the moment. My cum dripping down her face, the rug wet with her lady juice. I have masturbated with my sister lots of times, but this was the first time she ever let me ejaculate on her face and I loved her for it. No other girl had ever let me do that and she knew it was a fantasy of mine for years. We had talked about our fantasy before, while watching each other stroke to orgasm.
'Merry Christmas Matthew' she blew me a kiss as she left the room, off to take a shower.
'Merry Christmas' I shouted back.
