I'm eighteen now, but was only sixteen when this all started. Having had to move out of my moms home (Her new husband and I don't get on at all) I went to live with a woman who on only the second night in her home, seduced me. I was in bed at the time asleep. When she lowered her pussy onto my face. I tried to say something, but through whispered teeth, she told me to lick her "c**t". Knowing who it was, I tried again to say something, but she just pushed her pussy harder over my face, smothering me a little. Finally a I gave in and gave her what she wanted.
It was no more than five minutes later with my tongue lapping away at her pussy, clit and asshole that she came all over my face. Settling down, she moved around uncovered my body and lowered my boxers. I'm no Adonis, nor am I very muscular or overly athletic. What I do have and she knew this, is a long fairly thick cock. Taking hold of my cock, she lowered her head and began to suck on my full length, taking extra time sucking in my large helmet. Back then I was a virgin and although I'd masturbated a lot, I didn't last long and was soon shooting my cum down her throat, as she swallowed every drop. Removing my cock from her mouth, she told me to keep it between us and that when possible, she'd suck me off but only if I gave her oral pleasure. In the gloom of my bedroom I smiled and said okay.
Every day it seemed over the next few months, she and I had oral sex. I became if I do say so myself, very accomplished at performing cunnilingus, always making her cum violently. Our sex was mostly at night once her husband had collapsed from drink, but sometimes we had sex during the day, especially if he was playing golf.
Then one evening, not long after my mom had left and her husband had gone to the bars with his buddies, she asked me to follow her up to her bedroom. Not at any time had we had oral sex in their bedroom, so I knew from that and the fact she had condoms we were going to fuck. As usaul we had oral sex, amazing oral sex and then she mounted my straining cock facing away from me. As my cock sank all the way into her hot c**t, she told me to slide a wet finger up her ass. Doing as I was told, she rode me like I was a redeo horse. She had taken my cherry and I couldn't have been happier.
We stayed in their bedroom fucking for over an hour. An hour in which I learned many many things about sex and how to fuck a woman. Having removed the condom, she had me fuck her from behind, but deep up her asshole. Not wanting to boast, she tod me before she came, I was the best lover she'd ever had and then promptly orgasmed. She was shaking like a leaf in a storm and moments later my cock unloaded up her tight super cute asshole.
That was it for us, every chance we got from then on we were fucking. It was morning noon and night some days and even being young, it was hard to keep up with her insatiable sexual appetite. Then the inevitable happened. Fucking her anally on the couch one evening five months ago her husband walked in on us. Amazingly he laughed, smiled at me and said "If you can keep up with her boy, she's all yours to fuck". He went to bed drunk and we carried on fucking. And we've been fucking ever since.
So far he hasn't told my mom that I'm fucking her. But then why would he embarrass himself, by telling my mom he can't keep up with her sisters sexual needs.
