Invite him to watch.

The attention is flattering, and puts you in a bit of an exhibitionist mood. "See something you like?" you ask nonchalantly, curious to see if you can take this anywhere.

Ash seems tongue-tied for a brief moment; then, you see him relax in a way he hasn't since he walked in. "Y'know, actually, yeah, kinda. I gotta admit, this is pretty hot."

"Aw, thanks," you say with a chuckle. "Well, you don't have to leave if you don't want. I don't mind an audience."

You see hesitation creep back into Ash's bearing for a second before he pushes it aside. "Sure, I'd like that."

Glancing down, you see the front of those grey sweatpants he has on has started to strain noticeably. "Wanna show me your dick?" you ask plainly.

Ash shrugs. "Yeah, alright." Pushing down the waistband of his pants, he lets them fall around his hooves and steps out of them. Freed of its confines, his own flared equine cock quickly emerges the rest of the way from his sheath. His lacks yours' mottling, the skin an even black all over from base to tip. The sight makes your mouth water and your own dick strain against your grip.

"Oh, that looks good," you sigh, uninterested in holding back your thoughts.

"Thanks," Ash replies with a chuckle of his own, though his still sounds a little uncertain. "I've, uh...I've never done anything like this with another guy."

"You're missing out," you say with a grin. A naughty impulse coming to you, you lift up your heavy ballsack from where it hangs between your thighs to reveal the sparkling base of your buttplug.

Ash's breath comes out as a soft snort. "Oh wow."

"Like it?" You spread your legs wider, blatantly showing off.

He nods slowly. "Yeah, that...that looks really good." As he stares, transfixed, a large drop of precum gathers at his cockslit to fall to the floor, leaving a thin strand behind to glisten in the air. "Does it feel good?"

"Fucking amazing," you confirm. "I mean, not, like, enough to make me cum by itself, but I love how full it keeps me. I feel like a total slut when I wear it."

"I bet." A smirk crosses Ash's face. "You look like a slut right now."

The words send a shiver through your whole body; you whicker with pleasure. "Thanks. I am a slut. I love showing off my slutty body."

This whole situation is turning you on even more than you'd imagined. You really hadn't planned on doing anything with Ash, but given how receptive he seems to be, the prospect is starting to seem more and more appealing.
