Part II: Sunday

You wake up, blinking and groggy, to sunlight hitting your face. As you roll over, you notice a gentle pressure on your cock. Glancing beneath the sheets, you see a small, well-manicured hand lightly gripping it. You let your eyes wander from the hand, up along the arm, and rest your gaze at the small pink nipple peeking out atop a pert, well rounded breast. You stare at it rise and fall in time with her breathing and feel your cock start to stiffen. Smiling, you look upwards at Karen's sleeping face and marvel at how beautiful she looks, and how sexily she let you coat her face with your cum last night.

As you return your gaze back to her breasts, you start willing your cock to be hard. Her loose grip on it enhances the sensation on your prick and it does not take long for it to swell into her hand. You gently jerk your hip, letting her hand loosely fuck your growing cock. Meanwhile, you wet your finger with your tongue and start to gently rub circles around her nipple, watching it slowly rise and harden in response.

A few weeks back, Karen had asked you if you wanted to try out sleep sex.

"You mean fuck you while you're asleep? But what if you aren't in the mood, babe? I would be forcing myself on you."

"Yeah right, Mark. How many times have I not been in the mood to fuck you?"

You grin. She was right; her libido was quite high. You suspect it might be even higher but she was letting you keep up.

"Look just do whatever you want with me, at least whatever you usually do, but try to do it without waking me up."

"So I give you a nice wet dream?"

"That and a orgasm so good, it'll wake me up. I've been fantasizing about it: waking up to a mind blowing orgasm while I feel your cock throb and fill me with cum."

You hadn't needed much encouragement after that. You both decided that whoever woke up first got to have fun with the other. And after your initial doubts about consent, you found out that getting your way with her body without her even knowing about it was hotter than you imagined.

After her nipple becomes fully erect, you gently bend your head and lick it slowly, savoring the hardness with your tongue as you stroke her other one. Karen's nipples are your favorite part of her breasts, and that was saying a lot considering how sexy and full her tits are. Her nipples were about half an inch fully erect and formed perfect little peaks. You could spend hours sucking them, rolling them around with your tongue until they were sore and Karen begged you to stop.

"You just love to suck them because they're like sucking little cocks," she teased you once, laughing.

"Ew, cocks," you replied, making a face. "Cocks are ugly and slimy: I have no idea why you like sucking them. Besides, you know I don't swing that way. Now nipples, your nipples, on the other hand..."

"Please cocks are cute and I love how quickly they can get wet and slimy for me. Honestly the best part about them is that cute cocks generally have cute guys attached to them. Especially guys who like to get their cocks all hard and wet, and then like dumping their warm, tasty, tasty cum in my mouth..."

She stopped abruptly and tackled you down, aggressively sucking your dick off. True to her word, she loved it when you came in her mouth, letting your tip feel the vibrations from her moans and her swallowing until it was sore and it was your turn to beg.

When both her nipples are fully erect, you kiss them softly and run one last probing tongue over them, enjoying the little bumps they have where her nipple piercings used to be. Apparently she got them in college but had lost interest in keeping them after she graduated. Then you run your tongue in gentle laps around her breasts and down her stomach, pausing for a bit to lick her sexy navel. Meanwhile your hands gently squeeze and rub her breasts, relishing their firmness. You feel her breathing change and become a little quicker. You hope that she's beginning to get a nice sexy dream.

You crawl over to her waist and legs, moving the sheet aside, exposing her well toned legs and shaved pussy. Karen didn't really enjoy working out, but she made an extra effort to when she noticed how much you loved stroking and kissing her legs and ass.

"I'm not losing you to some other long legged, tight-assed slut," she once said in mock seriousness. "The only long legged slut in your life will be me."

"Of course babe. But please, I'm never going to cheat on you. You're my lover, you're my mistress, you're my girlfriend... and you're my slut."

"Ok Mark. I won't tease you." Then getting on all fours she spread her legs wide giving a very clear view of her puffy pussy. "Now why don't you give your mistress what she desires."

"At once ma'am," you grin as you bend down and start licking her pussy. "I will serve to your full satisfaction."

"Oh I will see that you do," she gasped as your tongue started to stroke her clit, making her juices leak slowly down your face.

You gently stroke her thighs, feeling the firm muscle and remembering how tightly she can wrap her legs around you, pushing you deep inside her. You enjoy the memory, letting your cock get harder and more erect. It is almost at full mast: at five and a half inches, just about average length but almost as thick as your wrist. Karen loves how thick you are. It makes blowjobs a lot more challenging to her, but she loves how your cock can fill her pussy up. Sometimes you would lie still inside her and she would just clench and unclench her pussy to orgasm.

You spread her legs apart and bend your face down to her pussy. Her pink lips are already slightly open and you get a faint whiff of her wetness. It was a surprise even to you that the scent of her horny pussy was such a turn on. Karen really benefitted from this fetish of yours: you absolutely love spending time between her legs, licking her pussy, even using your nose as a tiny dildo, as you bask in the moist, tangy vapors.

You first move lower, tracing your tongue very gently around her ass cheeks and then slowly moving to the dark star in between. You rim her gently and then quickly move back to her pussy before it gets too wet. This was your guilty pleasure, since Karen had no idea you liked rimming her and you didn't want her to suspect. While you loved kissing her ass and burying your face in it, you kept away from her anus. The two of you had never talked about anal, and you felt oddly shy about broaching the topic to her. On top of that, sometime back you had your first prostate exam and it had left you feeling very uncomfortable and slightly violated. Knowing how thick your dick was, if Karen ever wanted anal, you would definitely need a lot of convincing to fuck her ass. However, you did realize very quickly that you loved licking her asshole and used every opportunity to satisfy that need, even if it was just for a few seconds.

You start running your tongue around her pussy lips, slowly inching your way to the hood of her clit. After giving it a few sucks, you start lapping her pussy in earnest, using long strokes with your tongue. After a while, you feel her breathe faster and soft moans start escaping her mouth. Her thighs tighten around your face. You gently push a finger in, gauging her wetness. It goes in easily and you can feel the heat in her pussy. Your cock starts to twitch and you feel your balls starting to swell a bit. You grit your teeth and try to hold on. She's quite wet, but you want her wetter and hornier.

You start sucking gently on her hood, teasing her clit out with your tongue. You push another finger in her and slowly push them in and out, enjoying the feeling of wetness within her. Your other hand moves back to cupping her breast, using your thumb to rub circles on her nipples.

Karen's breathing becomes more erratic and her moans are coming a little quicker and a little louder. You use the surface of your tongue to rub her clit as you keep sucking on it. At the same time you start moving your fingers in a "come hither" motion inside her, rubbing her G-spot in time with your tongue.
