>Twilight grunts, then moans, and her hips buck forward one last time
>She smacks against you, pressing herself further into you, her cock flaring inside your ass
>Her balls come to a rest on your own, and then start pumping
>As does her twitching marecock, which pulses against your prostate, pushing you over the edge and causing you to release your seed all over the bed
>Twilight's pumping and pulsing shaft then releases her hot cum deep into your ass, trapped inside by her flared cock and making you feel so warm and good.
>Little did you know, her semen was magically enhanced to fill you with that same bliss and happiness that a recently impregnated mare would
>Which you'd totally be fine with being.
>Twilight slumps over onto your back, and while her cock shrinks, it never leaves your ass, and the two of you spend the rest of the night in that position
------------------------------------------
>You wake up and untangle yourself from the sheets and purple limbs.
>While cuddling is great, you wanted to wash all the semen off that had dried on you.
>You draw a bath and quickly submerge yourself, groaning at how the warmth spreads through your limbs.
>As your head comes back out of the water you're greeted by a pair of purple eyes looking into yours.
>Before you can think to react the mare has splashed into the tub with you, laying full out against your body.
>The feeling of her body against yours in the water causes you to grow erect again.
>And if the hot mass growing next to yours is any indication she feels the same way.
>You smile and pull her into a kiss.
 
>You keep kissing Twilight while you move your your hand between the two of you.
>She moans into your mouth as you wrap your hand around both of your cocks, squeezing them together.
>You break the kiss to lay your head on her shoulder, whispering in her ear.
"You're energetic today aren't you?"
>"Y-yes!" she squeaks as you give a particularly vigorous pump, agitating the water around you both.
"You want to fuck me with this marecock of yours don't you?"
>Her body trembles as you speak and pump.
>"Yes!"
"You want to rut me senseless. With this. Big. Thick. Hard. Horsecock."
>"Yes!" she shouts as she cums hard, spurting cum between the two of your bodies.
>You nuzzle your head against her neck as you give a few more pumps.
"Well it's a good thing you get opportunities to."
