Foalsitting Aftermilk... math.

Big Mac made his way through town using a somewhat circuitous route to his destination. He was trying to get his mind off of that morning's revelation.

Soon he slipped into an alleyway and entered a building by a side entrance. Once he got past the second door his nose was filled with an extremely enticing scent. It was clear that the mare sitting behind the desk was in estrus, and she wanted every stallion who walked in to know it.

She watched as Big Mac strode up to the counter and flashed him a sultry smile.

"Bit early aren't you. Normally we only see you once every few weeks. Did some mare go and get you all riled up or are you here to see little ol me?" Hazelblossom said, leaning forward in her chair and bringing her arms in to emphasize her cleavage.

Her smiled grew more seductive as she saw the effect she was having on the large stallion. Drawing her eyes from the noticeably growing bulge in his pants she locked eyes with him.

Big Mac gulped as he got more than an eyeful due to her wearing her nurse's outfit with the top couple buttons unbuttoned. "Just a bit riled up, tho' tis always a pleasure to see you." He said.

She handed him a cup. "Well you know the drill, and do ask if you need anything. Room 5 is open right now."

As he took the cup her hand lingered a bit, drawing back teasingly across his larger fingers. He smiled tentatively at her before heading back towards his room.

Once inside he slipped his pants down allowing his cock freedom. Taking the lid off the cup he set both on the small table near him and sat in the chair and lightly stroked his stallionhood. Enjoying the small sensation as he ran his fingers along his length he allowed his mind to drift. Soon enough he was lightly daydreaming.

It started tame enough, imagining the bodies of some of the mares round town before landing on Hazelblossom. She was as he had just seen her, but now standing up and doing a sexy little dance number. Her outfit was slowly being shed enticing him more with a greater view of her well maintained body.

He wrapped his hand around his member and began stroking. The image of the nurse's lingerie brought about thoughts of Rarity and her fashionable clothing. He now had a prim and proper mare doing a very lascivious striptease. Soon she was down to nothing at all and grinding up against him while nestling his cock inbetween her plump ass.

His cock started dripping precum slicking his length letting him stroke it faster. His image of Rarity stepped away from him and with a hand stroke to his chin seemed to morph into an image of Princess Luna. The lunar diarch was wearing thigh high boots with a leather corset. Every bit the image of a dominatrix. He admired her form before shifting his thoughts hoping that her powers over dreams didn't extend to daydreams. He missed the smirk that appeared on her face just before Fluttershy took her place.

The timid mare was already in a skimpy teddy doll with lace stockings and almost too small thong. She moved forward before dropping down to her knees. She planted a kiss on his cockhead before licking around the shaft. She brought up her large breasts and wrapped them around the base and started to stroke his lower length with them. She brought as much of his cock into her mouth while continuing to work her breasts.

Big Mac could feel his cock pulsing with the desire for relief. Fluttershy moved up and straddled him leaving his cockhead at her wet and teasing entrance. He took one of her breasts into his mouth and played with her nipple with his tongue. As she started to press down her lips starting to spread around his girth a spurt of milk into his mouth reminded him of that morning.

With that thought the mare in his mind shifted one more time just as she speared herself onto his stallionhood. Applejack's breast was still firmly in his mouth as her milk began filling it. He swallowed instinctively as she kept taking inch after inch of him into herself. She bottomed out quickly and shook her hips causing Big Mac's balls to give a telltale lurch.

He quickly snapped out of his dream as his cock throbbed and quickly reached for the cup. Lining the cup up just in time as his flare indicated the imminent release of cum. As the spurts flew from his tip the cup caught them and was soon filled to the brim. The last strings of cum found themselves over the edge of the cup and on the table.

Big Mac reached over and grabbed some paper towels and cleaned himself up. Once done he slipped back into his pants and screwed the lid back on the cup. Noticing the mess he made on the table he wiped that up and disposed of the used paper towels.

Hazelblossom idly fiddled with her desk. She had her legs spread so that the small fan hidden underneath her chair could spread the small of her estrus across the room. She really enjoyed the effect it had on the stallions who came in to the family planning center to donate their seed. She eagerly awaited one of her favorite stallions to finish up.

As her thoughts strayed back to imagining Big Mac laying atop her filling her with his cock, his muscles tensing as he thrust, she heard a door open and close. Looking down the little hallway he gently strode back to her desk. She gave him a smile as she saw the cup in his hand.

"You really filled it up this time. Even got some on the side." She said when he placed it on her desk before taking a finger and picking up some of the stray cum and bringing it to her mouth. "Such a satisfying taste." She stated breathily.

Big Mac blushed deeply as she wrote out some information onto the cup and placing his donation into a small bag. Her eyes catching the sudden jerk in his pants at her little display.

"You know, I've had my eye on you. Been wanting a nice young foal for some time, so just maybe I'll make a withdrawal myself." She stated willfully, taking a deep breath to draw Big Mac's eyes to her chest.

She heard his breath stop short at her efforts. "Though if a big strong stallion was willing, I would prefer a much more natural way of conceiving."

Her hand caressed his forearm, hoping to drive her point home.

"E'yup." Big Mac coughed once, "E'yup, natural would be best." He said, his blush causing his face to appear twice as dark red as the rest of his coat.

"Would tomorrow be a good time? We can grab some dinner first, you'll need every bit of strength and stamina farmwork has given you to keep up." Hazelblossom said quite teasingly.

Big Mac nodded. "Pick you up round 6. Have a nice day Hazelblossom." He stated before turning towards the door.

Hazelblossom smiled wide enough to match one of Pinkie Pie's. She put the same information on the cup onto the bag before opening a small door in the wall behind her. She placed the cup into the small fridge for the lab on the other side to run their tests to ensure the virility.
