Let's do her doggy style

Figuring you should give the sisters equal treatment; you decide it would only be fair for you to fuck Danielle doggy style too. "Roll over." you tell her, sliding your cock from her sheath. "Get on your hands and knees."

A look of wanton lust is on her face, and she quickly complies, rolling over and sticking her round ass into the air, caring only about having her needs satisfied further. Danielle is definitely the more fit of the two and you take a moment to enjoy the view of her narrow waist flaring out to her plump ass without any sign of cellulite. The site below you increases your hunger for her and you quickly stick yourself back inside her.

"Oh shit David, I love your fuckin' cock! You hit all the right spots with it! Where has this dick been my whole life!?" she says as you settle back into place.

Grabbing hold of her hips, you get back to work, slamming in and out of Danielle's hot, wet cunt with reckless abandon. Your breathing becomes labored as you dole out your punishment, sweat is beading up on your brow and chest, and you feel your balls slapping against her clit with every thrust. Looking down, you get the visual stimulation of her narrow waist flaring out to her jiggling ass and her brown, puckered asshole winking up at you.

It takes less than a minute's work of slamming into the horny MILF below you before Danielle announces to you "OH FUCK! You're gonna make me cum on that fuckin' dick again!", then her screams are once again filling the air and her body is trembling as you bring her to another orgasm. Not caring about prolonging your session any longer, you keep up your frantic pace, and the rhythmic clenching of her tight hole soon has the pressure building in your loins, and you know you won't last much longer.

You continue pounding into her for as long as you can, letting her enjoy her orgasm for as long as possible, but once the feeling of your imminent release starts to wash over you, you **** yourself to pull your cock out of her grasping cunt and order her to get on the ground and onto her knees. You had given Alyssa the choice of where she wanted you to cum, but you don't plan on offering Danielle the same option. Standing from the couch, you take your cock in your hand, wanking it furiously over her while she stares up at your glistening member with enraptured anticipation, well aware of what's about to happen.

"Yeah David! Jack that fat cock! Blow that hot, sticky load all over my face! Treat me like I'm your dirty, little cum rag!" she begs you, before opening her mouth wide.

Just as she does so, you let loose with an almighty groan, your rapidly pumping fist flinging your seed onto her, splashing her cheek, mouth, and chin, with some even landing on her chest. As would be expected with the number of times you've cum already today, this load isn't nearly as impressive as your last and you quickly find your contractions slowing.

As you let your hand fall from your rapidly softening member, Danielle grabs you by the base and squeezes tight, preventing any more blood from escaping and brings the throbbing head to her lips. "Let me stick that dick back in my mouth so I can get a taste of my pussy on you now." she says with a playful grin before slurping your member into her mouth.

The sensation borders on being painful as Danielle begins voraciously sucking and licking along the length of your dick. "Mmmm... Mmmm... Mmmm!" she moans, mouth full of your cock and unable to actually voice any words. She continues sucking on your knob, slurping every last drop of your semen from your balls, then pulls away and makes a show of swallowing it down for you.

Once she finally lets go of your softening member, you flop down onto the couch in exhaustion, letting your head fall back, then you watch as she climbs to her feet and walks over to an end table that has a box of tissues on it. Pulling one from the box, Danielle proceeds to wipe your cum from her face and chest, then, turning back to face you, smiles at your spent form. "Looks like you're probably done for the night, but maybe you'd like to stay here and have another go around in the morning? I think my sister ended up passing out in her room already, but I'm pretty confident in speaking for her in saying she'd be more than happy to have that cock for breakfast. I know I would be."

As much as this seems like a once in a lifetime opportunity, your chafed dick is already starting to become painful, and you're pretty sure you're going to need multiple days to recover from your adventures today. Thanking her but declining the offer and telling her to wish her sister a happy birthday, you gather your clothes, slip them back on, and say your goodbye. As you begin your ride home, satisfied but completely worn out, you smile as you think about the day you had, and start looking forward to the next weekend.
