It's... Chocolate?

Your eyes widen as the familiar, sweet flavor hits your taste buds and you quickly pull your mouth back to see that the trickle of milk is indeed the brown colored as it dribbles out of her hardened tit. Seeing your reaction, Susan looks down as well and she raises an eyebrow. "Let me guess," she says, "You were a bit fussy with cow milk once you were weaned."

A blush comes to your cheeks as you swallow your mouthful and nod sheepishly. "Maybe a little."

"It's not as unusual as you think," Susan says as she reaches up to ruffle your hair and then starts guiding you back down, "Though I've learned over the years different women have different flavors when the spell works this way."

Not putting up resistance, you let Susan return you to her waiting nipple, once more engulfing it with your maw. As you begin suckling more intently, you start wiggling your hips, rubbing the bulge in your underwear against the growing damp spot on hers. She bites her lower lip lightly, a soft stream of air puffing out of her nose as you stimulate both her chest and crotch. Your hands start to drift lower down her body, following the glowing lines you can sense more than see at the moment down to the waistband of her panties. Lifting her hips, Susan lets you ease them down enough so that you can expose her dripping slit, the hair above it waxed away to expose an unexpected tattoo of a snake-like, black dragon circling around a red rose. Your forefinger traces the outline of her lower lips, stroking along the length in time with your suckling.

The chocolate milk is rich and delicious tasting... but also a bit on the filling side as you have already drunken the equivalent of two glasses full and Susan clearly has more to give. Seeing your expression, Susan lets your head go and pushes back on your chest so that she can slide out from under you, kicking her panties the rest of the way off as she stands, and give you a nice view of her plump behind as she starts digging into her bag again. "This is a bit much to take in one session," she says as she pulls out two glass milk bottles and returns to the bed, "So let's save some for... later."

She presses the opening of each bottle against each nipple and mutters an adhesion spell to make sure they stay in place as she gets on all fours, swaying her ass at you. The sight is something else, her nipples being forcibly stretched by the bottles as they lightly drip their creamy fluid into the container. "Time to milk your cow, Sweetie," she huskily coos before letting out an erotic sounding moo.

As you inwardly marvel at how this woman can make mooing sound erotic, you take off your final piece of clothing as well. Your hard dick juts outward, all but visibly throbbing with need, and you climb back up onto the bed behind her. An idea strikes you and you place a finger on the head of your manhood, let the magic energies flow through you and say, "Extro-Extremits."

You shiver as your dick is now two dicks, Susan looking over her shoulder and saying, "Cup your balls and use the word 'Capacitos Doublas'."

Following her instructions, you are surprised to see (and feel) your balls grow larger as well. "If you double-dick someone without adding that spell," Susan explains, "You run the risk of straining your testicles if the lady makes you cum too hard or too many times. So if you plan to get in the habit of using one, it's best to get in the practice of adding the other."

"So you've had guys do this before?" you ask, feeling a touch disappointed you could not surprise her.

"Usually most young men your age try the spell that makes their dicks a LOT bigger," Susan replies, "but I have... encountered it before."

"Is there anything you HAVEN'T encountered?" you ask incredulously.

"Weeeeellll," Susan says with a playful grin, "I've encountered all the ones we're doing separately but this specific combination is new."

Somehow, that makes you feel a little better as you move forward, lining up your cocks with both of Susan's lower holes. You quickly chant the lubrication spell before pushing inwards, grunting as her incredibly tight and hot cunt and anus welcome you inside by all but squeezing the life out of them. "Mmmmm," Susan sighs, "Lean over me and grab the base of my tits. Squeeze every time you push inwards."

Following her instructions, you lean forward, feeling the warmth of her back against your front as your hands reach around to take hold of her wobbling orbs. When you finally manage to hilt yourself, you tighten your grip as instructed and Susan lets out a moan of pleasure as a squirt of chocolate milk flows out of her nipples and into the bottles she has attached to them. You take several seconds to get used to the sensation of how both her front and rear entrances ripple around your lengths before you start to pull out and then thrust your way back inwards, squeezing the base of her breasts again and drawing another lovely sounding moan along with more milk.

It does not take you long to start building up your momentum, barely able to control your hips as you plunge in and out of the mature woman beneath you. Susan rocks back and forth in time with your motions, her breasts wobbling every time you ram home and squeeze your hands to cause more milk to squirt out of them. It is kind of amazing how she does not seem to be bothered by their weight, which has to be only getting heavier as every loud slap of your flesh against hers makes them a little bit fuller.

Your ability to remain focused on that amazement is short lived, however, as Susan wriggles her hips in a certain way and it feels as if her inner walls are milking you even more intently. "Oooh, this DOES feel good," she says, breathing intensely but still in control of herself, "I think I like being a fuck cow."

"Fuck... Cow... huh?" you grunt, as your thrusting and squeezing increase in intensity once again, the tell-tale tingling sensation in your cocks letting you know you are almost at your limit, "Is that what I should call you? My... Sexy... Fuck Cow?"

Susan unexpectedly shivers, responding to something in your possessive tone even as you see a lifeline across the back of her neck you trace with your tongue to her earlobe, which you give a tiny nip to with your teeth. "N-Never said... y-you'd be... the only one to do this to me, S-Sweetie," Susan replies, cocking her head towards the oral stimulation, "B-But if that's the nickname you want for meeeee..."

She lets out a small squeak as one particularly hard thrust and squeeze combination from you causes a practical torrent of brown milk to blast out of her nipples and, before you know it, the bottles are full. Somehow, without missing a beat in fucking you, she manages to remove the bottles from her chest and place them on the bedside desk. She then puts both hands down on the bed and REALLY starts to rock back against you and you know you only have a few seconds left at best.

"S-So tell me, Sweetie," Susan purrs as she licks her lips, "you wanna fill me up... or hose me down?"
