Hell yes, you keep going!

Though screwing around with your aunt might be a little bit of a morally grey area for some, you're both consenting adults and things have progressed to the point where you absolutely have to see this through to the end. Not willing to wait any longer, you move your left hand to the cheek farthest from you while subtly shifting your right hand down on the closest. Pulling her ass cheeks apart once again, you let your right index finger drift to her labia, lightly brushing against her outer folds. Feeling the damp heat emanating from her, you decide to push your luck further, massaging under the crease of her cheek while letting the tip of your index finger slip between her steamy folds, teasing in and around her opening with each kneading stroke.

"Mmmm, David, what are you doing?" she asks you, lifting her hips slightly to give you better access to her hole and obviously breathing a little heavier.

"Just making sure I don't miss anywhere." you reply, noticing she didn't ask you to stop. "Now, let's get these shorts completely off you. I think if I'm going to work on the spot that really needs my attention, they're still going to be in my way." you say as you move your hands to the waistband of her shorts and start pulling them down her thighs. Aunt Becky bends her legs up once you've got them past her knees, allowing you to easily slip them up her calves and off her feet and you toss them to the side, eager to get back to work on her pussy.

Freed of the shorts binding her legs together, your aunt spreads them slightly, inviting you to continue massaging her intimate region. Though nearly every cell of her body wants this, there's a small part of her brain that feels like she should be the responsible adult and put an end to this, but she's almost unable to say it out loud, her voice catching in her throat, as your fingertips find her labia once again, running along the length and splitting the lips apart. "David...you don't have to do this..." she says breathlessly, wanting to give you and out in case you're having second thoughts, but not able to bring herself to tell you to stop.

You smile as your fingers run along the length of her slit, the natural juices leaking freely from her coating your digits and letting you know just how turned on she is, and her choice of words letting you know she's not the one that wants you to stop. "But I want to do this Aunt Becky. And by the feel of things, I think you want it just as much as me." you tell her as you slip two fingers inside her opening.

"Ohh god!" she moans out as she reflexively brings her right leg up, giving you an even better angle with which to penetrate her, and relieved that she no longer has to suppress her desires. Already primed from her earlier session with her dildo, your fingers easily move in and out of her slippery tunnel and you quickly increase your pace. You're spurred on to even greater speeds as the intoxicating scent of her pussy begins to waft up to your nostrils as she continues groaning and begins moving her hips in rhythm with your hand.

"Mm... Mm... Mmmm..." she moans out through pursed lips with each plunge of your fingers, the volume of her moans getting louder by the second. She lifts her ass up into the air for you, arching her back and letting your fingers penetrate a little deeper, but the angle you've got still isn't allowing you to fully plunge your fingers into her. Stepping towards her feet, you're able to turn your hand over, palm down, so that your fingers can curl around her pubic bone and reach new depths. This different hand position also allows you to begin stimulating her G-spot and her reaction is immediate. "Oh David! That's the spot, right there! Holy shit!" she screams out, clawing her hands into the couch.

Whether she's just someone who orgasms easily, she's still on edge from her earlier masturbatory session, you've just got the right touch, or maybe some combination of these, it takes only seconds for your aunt to begin cumming. Burying her face into the couch to muffle her cries, her body begins convulsing, trembling as charges of electricity course through her loins over and over again. You feel her contracting around your fingers as you continue to slam them in and out, her vaginal muscles pumping her juices out from her insides and glazing them up to your knuckles.

Once you feel her contractions begin to slow, you bury your fingers inside her once more while curling them down and pulling back towards you, placing increased pressure on her G-spot. Her vaginal walls clamp around you, locking your fingers in place as the new stimulus causes her to squeal out loud, her orgasm peaking once again. Keeping your fingers buried in place, you let her ride out the final waves of her orgasm and wait until her trembling comes to a stop before slipping them from her slick honey-pot.
