Sexy immortality

"And that's for real?", asked Dash incredulously as she stood across from Twilight. Her muzzle was twisted into a wide grin and her eyes twinkled expectantly and delightedly at the lavender alicorn standing across from her.

Twilight nodded eagerly. "It really is true. As you know an alicorn is immortal, and also remains young forever. The four of us are so fertile that we four princesses alone could repopulate all of Equus in no time at all. I do not hope that it will ever come to that, but it would be possible. But…that wasn't your question...", Twilight scratched the back of her head in embarrassment. "Sorry!"

Dash laughed. "You're right about that, but it was pretty high up there too. So nice to know without even having to ask. Would you mind answering the question for me anyway?". The cyan pegasus tilted her head to the side and looked at her alicorn friend.

"Oh yeah, sure, sure," Twilight's words somewhat overlapped as she gathered her thoughts.

"Back to your actual question. You wanted to know if an alicorn is really so tremendously reproductive that even our sperm or mare-honey improves vitality and health when in intimate contact. That is also true. More than that, in fact. Not only do my fluids heal and strengthen your body, they can or rather do extend your life."

Dash´s eyes got wide as she heard Twilight saying that. "That means if I eat you out regulary, it will strengthen my health and make me more awesome than I already am?" She then cleared her throat. "Well if that would even be possible, I´m already the most awesome pegaus there is." Dash remained grinning wide as Twilight just rolled her eyes. "Whatever you say."

Dash didn't seem to have heard her friend, or was ignoring the alicorn. "Or if you mount me and we have a solid intercourse plus you having an orgasm inside of me, will that enhance my life as well? And where is the limit? How far does this effect go?"

That were quite a few questions at once, but Twilight would gladly answer them all for her prismatic friend.

"As you already suspected, both guesses are correct. Eating my equine pussy, as well as mounting and having sex with you would improve your health greatly. Coming back to the last one...there is no limit."

"What really? You could keep me alive with that - forever?" Dash raised her eyebrow, she certainly didn´t seem to have expected to get that kind of answer from Twilight.

"Yes!", Twilight simply replied.

"Well, what are we waiting for then?" Dash turned around, flicked her tail to the side and as she braced herself with the front hooves against the crystal wall spread her back legs as wide as she could. It gave Twilight the perfect view of Dash's most secret private bits and the alicorn would have been careless not to seek out said offered place for mating.

While Dash still braced herself against the wall with her front hooves more firmly, Twilight walked behind the prismatic pegasus and placed her own hooves on the wall just above the other mare´s head. She then flexed her rear legs and slowly hoisted herself up behind Dash. Slowly, the alicorn thrusted her hips forward and pushed her mighty marecock in between her petals and deep into the Pegasus' slick marehood. She then began moving in and out in slow trusts that became firmer and faster the longer her horsecock was caressed by the small ridges inside of Rainbow´s love tunnel.

Anyone who would have been witness outside the doors to Twilight´s private chambers in her castle would have heard loud and lustful moaning of two mares deep in sexual pleasure for hours. Neither of them knew - or cared how often they came to an orgasm, but soon Dash´s middle was bloated with Twilight´s high fertile alicorn-seed and there was no end in sight of either of them slowing down in the near future.
