Cowgirl. Kelly wants to ride your cock

"Do you mind if I start off on top?" Kelly asked sensually, biting her bottom lip while standing over you as you remained seated on the couch. "I think I'm gonna need to have a little control the first time this big dick of yours stretches me out."

"Go right ahead, but don't expect me to lie here and let you do all the work. I'm still an active participant, even when I'm on the bottom." you replied with a smirk, leaning back to get comfortable on the couch.

"Oh, I had that feeling about you. Just let me get warmed up a little first." she requested as she climbed onto the couch with you, swinging a leg over your hips to straddle your body. Grabbing hold of your cock, she guided you to her opening, used the tip to part her pussy lips, then lowered herself onto you. Kelly was already dripping wet with arousal and your spit-coated cock was met with little resistance as you found half your length quickly sucked into her hot, velvety, smooth walls.

"Holy shit, it's so thick!" she squealed out before biting down on her knuckle to stifle her cries, her muscled insides constricting in response to the unfamiliar stimulus. It took a short moment for Kelly to regain control of her body, but then began grinding her hips, inching herself onto you until she had worked your cock fully inside her creamy walls. "Fuck David, your brother's dick never gets this deep inside me. I already feel soooo full." she told you as she started slowly moving up and down your shaft, leaning forward to place her hands on the armrest for support, resulting in you now being face to face with her tits. "Just lie there for a little bit and let me do the work. I want to feel every inch of you sliding in and out of me. Don't worry though, I know I'll be begging for you to pound into my pussy soon enough."

Letting your head rest against the back of the couch, you grabbed hold of her plump ass, caressing the two, thick globes while enjoying the site of her tits inches from your face, and taking the opportunity to flick your tongue across her nipples when she moved close enough, each time, eliciting of gasp of pleasure from her lips. "Oh shit David, I forgot how good it can feel to be fucked by a new dick for the first time... Mmmph!... Oh yeah!" she groaned as she withdrew all the way to your tip, then settled back onto you, fully sheathing your member inside her, before repeating the same process again and again.

It soon became apparent that Kelly preferred the feeling of your thick cock fully stuffed inside her void and she started shortening her movements, increasing her speed, and grinding her hips on you while keeping the entirety of your length buried inside her as the volume of her grunting and groaning steadily climbed. At this point, you became tired of only being a passive participant and began matching her movements to penetrate her a deeply as possible. Kelly didn't object at all with you taking the initiative and, was soon groaning even louder and you could feel her insides clenching you as her juices began leaking down onto your ball sack. The two of you were starting to get into a good rhythm and you thought, in all likelihood, that you'd continue like that until completion, but the next moment something changed and she let out a cry, then was burying her head in the crook between your head and your shoulder and her entire body went rigid. Taking your cues from her, you stopped moving, unsure if she was in pain, and waited her out. It took several moments, but she eventually lifted her head and looked at you, her eyes watery. "Are you OK?" you asked concerned, not sure if you hurt her, or if she suddenly had second thoughts about what the two of you were doing. "Do you want to stop?"

"Oh my god David, no! I'm fine! You just hit a spot and I didn't know what to do. It was like an electrical shock went through my whole body." she said giggling lightly and wiping her eyes. "It just caught me by surprise, that's all. I kinda wish you kept going, but I think I might have literally passed out if you did." she said, pausing before looking at you with a wicked grin on her face and continued with "Let's see if we can make that happen again.", then began grinding her hips into you once again.

Kelly didn't need any additional time to get used to your member and was soon riding you with vigor, the head of your cock bumping into her back wall every time she ground her exquisitely smooth and slippery pussy into you. Her face was pure pleasure, eyes squeezed shut and mouth agape, and the slapping of flesh on flesh was soon joined by Kelly shrieking out as her first orgasm shook through her body.

You let her waves of pleasure come to a halt and waited until she opened her eyes before suggesting a change in position, asking if it would be OK to lie down on your back so you could see her ride you cowgirl style next. Kelly grinned, happy to oblige, and you managed to keep yourself impaled in her velvety tunnel as the two of you shifted positions. Once you were fully on your back, Kelly leaned away from you, placing her hands above your knees to support herself and giving you a view of your dick disappearing between her swollen pussy lips and smiled at you as she began rotating her pelvis on yours. "You like how that looks, David? You like seeing your sister-in-law's sopping, wet cunt stuffed with your big, fat dick?" she asked you, biting her bottom lip.

"Oh god yeah, it looks amazing! Fuck Kelly, you look amazing!" you replied, grabbing both of her hips and thrusting yourself up into her, more than ready to resume the action.

"Oooooh, you dirty, fuckin' bastard, I can tell you like it! Your dick is so big and hard inside me!" she told you as her pussy gripped your shaft from inside her. Your eyes nearly rolled into the back of your head at the indescribable feeling of her vaginal walls rippling around your cock, tightening and loosening rhythmically, squeezing you without the use of her hands. "Oh fuck, I can feel how much you love it when I ride you like this. Those heavy balls slapping my thick, round ass and that big, meaty cock completely filling my hot, wet pussy!" she said as she began riding your cock with renewed enthusiasm. "Fuck David, you're rubbing my g-spot over and over!" Oh fuck! I can't believe it, I'm gonna... I'm gonna..." but before she could finish her sentence, her words trailed off and turned into a scream as she came on you again, her walls tightening and spasming around your pole.

This time, neither one of you slowed your pace and Kelly's wails of pleasure continued to fill the air as the bulbous head of your cock bottomed out against her cervix. "Ugh, I love your fucking cock!" she screamed out as she continued bouncing on your cock. "Oh David you make me so fucking horny! I want you to cum for me! I want to make you cum!"

"Fuck Kelly, you've got me so close! Where do you want it?" you asked her in ragged gasps.
