>When you first arrived here the princess of friendship, the purple one, assigned her pupil, Starlight to be your guardian while you integrated into pony society.
>She was responsible for your well being, including emotional and carnal.
>You were a bit shocked when you first began having sexual urges towards mares. You couldn't even admit it, but she was able to figure it out.
>She reassured you it was okay and that as your friend and guardian she'd pleasure you to alleviate your desires.

>You tighten your grip on her shoulders as you thrust even harder into her.
>She locked her legs and braced her body against your thrusts.
>Her body didn't move more than an inch, but her fat ass bounced and jiggled like jello cake during an earthquake.
>Despite this, her face betrayed not even the slightest pleasure or discomfort. And her breathing was still at a resting pace
>Your strokes were hard and deep, but she seemed unfazed. She just stiffened her hindlegs and braced herself.
>The only vocalization from her were words of reassurance given in a totally casual and nonchalant tone
"Take as long as you want; get it all out. Only stop when you're fully satisfied."
>On the other hand you were moaning like a girl getting her guts busted. You couldn't help it, her pussy was good, too good.
>It was so tight and wet, and she had perfect muscle control.
>She squeezed the hell out of your glands and frenulum with each stroke.
>Something about her causal attitude made it so much hotter
>She shifted her weight and reared up a little more for you.
>You lost it. The heat, moisture, the muscles massaging your cock, her perfect ass bouncing with each stroke, her scent, her soft fur... You couldn't handle it. You were gonna cum.
>You moaned like a bitch and started sloppily kissing her neck as you came deep inside her.
>She tuned her head back towards you.
"You can keep going if you need to."
>You kissed her and she returned the favor for a few seconds, but turned and offered you her cheek when you tried to slip your tongue in.
>You slumped over her and kissed her neck and shoulders as she massaged your cock with her pussy.
>You groaned and ran your fingers through her mane as she milked out the last few drops of cum from you.
>After you were completely drained she used her magic to hoist you onto her back so she could carry you to bed. Her coat felt so good on your balls.
>"Can I sleep with you tonight?"
>She pondered it for a moment.
"Sure, why not?"
