Anal sex

You had been preparing for this for weeks. Zephyr had asked you about trying anal sex with you. You had received it from her a few times. It felt closer to how you assumed vaginal sex with a human would feel on your end, and she had enjoyed it too. However, this was your time to take her. You had been working together, stretching, exploring, using fingers and dildos, and working your way up to taking her equine tool.

Now you were bent over your bedside table, lubed up and bracing; you cock semihard with anticipation. Zephyr stood over you, front hooves on either side of you, her hard cock lined up with your back passage.

"Are you sure about this?" You asked tentatively. "It's so huge."

"It should be fine." Zephyr reassured you. "You've been doing your butt stretches, and you put plenty of lube on it." Referring to both your ass and her cock.

"Yer, but still..." You cut yourself off. You felt her cock pressing against you and felt ready. You relaxed and let the tip enter you. You felt yourself stretch open more than you had before. "AAAAAAAAAAAAAAAAA!" You cried out.

"Are you ok?" Zephyr asked with concern. "Should I pull out?" she said softly and kindly. As much as she wanted to try this, she didn't want to hurt you.

"No...It's fine" You said between breaths as your body adjusted. "Just go slow.

"Mmmm" She moaned as she began to gently and slowly move the tip in and out of you. "Mmmmm" she moaned again.

"Ah Ah" you began to moan with laboured breaths, experiencing both pain and pleasure.

"Ah Ah Oh" She moaned as she thrust slightly deeper but kept the pace slow.

"Oh Ah" You moaned, pleasure overtaking pain but still feeling overstretched.

"Oh, Oh, Ah" she moaned with each thrust, feeling the pleasure build as your ass squeezed around the tip of her cock. She picked up the pace, thrusting faster but no deeper. "Oh, babe, I'm almost there! I'm going to cum!" She cried out in pleasure, warning you.
