As you stand before the mirror, continuing to admire your awesome stallion self, there's a knock at the door.
"Hey Darryl, are you done in there?"
It's your roommate, Sean. While you have landed a job at an office, he is working on a post-graduate degree while holding a part-time job at a fast-food place. You met in college, and have gotten on pretty well since. Standing at 5'10" -- about your previous height -- he is rather handsome in an average way. Dark brown hair, deep brown eyes. Keeps himself fit despite his job and studies.
You're about to answer him, when you pause to think a moment. If you say "yes," and your words are always true, what will that bind you to? You know Sean; he almost always takes a shower when he gets up, and after last night he will definitely want a shower. And you wouldn't mind having some more fun in here -- with him. You smirk.
"Define 'done'." You smirk just a bit more at the sound of your own voice. It's a bit rougher, deeper, more resonant; but still recognizably yours. Like the rest of you, it carries the authority and wild force of a prime stallion.
"What the hell, Darryl." He tries the door, and it swings open. "I want to take a shower and --"
You turn to face him, looking smugly down on his little human body; hands still on your hips as you gently shift from one hoof to the other. He gawks for a second at your muzzled face, then his eyes trail down, till they fix on your stallionhood. 14 inches of thick male flesh pointing up at him.
"Oh. Oh my God. What."
You chuckle, soaking in his wonder, his stupefaction. The twitches in his boxers, the warm blood rising to his cheeks.
"Take a good look, Sean. Feast your eyes on the new and improved Darryl." You flick your tail, enjoying the feel of the long silky hairs on your powerful legs as they stir your scent around the room. You continue to slide your hips a bit, grunting as it makes your erect member sway. "You like what you see."
It wasn't a question, and Sean blushes fully.
"I-I, er, I'm not... not into... furries..."
"You are now." You put a hand on his shoulder as his blush deepens, and you can see his boxers start to tent. "Don't worry, dude. It's nothing to be ashamed of. Just let go of your fears, and embrace it. I'll protect you from anyone who'd make fun of you."
You give his shoulder the lightest of squeezes. Warmth surges through you; the knowledge that you can stand by your words, pride and happiness in being able to take care of your friends like this. Together of course with the power your body has over this flustered little man.
"Now, you were going to take a shower, right?" You consider how to word this as he nods. "How about I shower with you? It'll save time, and we're friends." You smile reassuringly. "It'll be fine."
"But -- what --" he stammers, looking down at your massive cock, obviously imagining sharing the confined space with it. You huff in his embarrassment and arousal, enjoying the delicate scents threading through the blanket of your musk.
Being a stallion is awesome.
You bend down a little, and use your other hand to tilt his chin up, making him look into your smouldering green eyes.
"Hey." Your voice carries the warmth you feel, manly and reassuring. "It's fine. Friends can shower together." You smirk a bit again, and playfully add, "Besides, don't you want to get closer to the stallion you love?"
"Ah." He stares back, bewildered by the new feelings he has for you. He did not expect to open the door and find a giant anthro stallion in here, much less be attracted to him. But his desire for you has exploded at your words, and now he finds his heart beating faster as he meets your amorous stare. But this is so different for him, at odds with what he remembers about himself. He shakes his head, trying to settle the confusion. One thing he can't deny though -- he loves you. He's known and been okay with you a long time; maybe he just needed to see you like this for it to blossom? His lust is harder to process, but he can't deny the throbbing in his boxers either.
"I... I g-guess...?"
"Great!" You chuckle, squeezing his shoulder again before turning to the bathtub. You pull the curtain back with a flourish, and gesture inside. "You first."
He gives you a small smile, nervous but also hopeful. He gingerly manoeuvres his boxers over his erection, and carefully steps into the tub. You move to follow, then pause, contemplating how your hooves will interact with the tub. Sean doesn't really notice, still trying to figure out what's going on and how he feels about it. You come up with a way to preempt any unpleasantness, disguising it as a joke.
"It's a good thing this tub is safe for my hooves."
"Y-yeah..."
"And my hair doesn't clog the drain."
You are satisfied with your forethought for a second, clomping heavily into the tub behind Sean. Then you are distracted by more important things as the flanged head of your penis kisses his back. You snort, amused as he jumps, and pull the curtain closed. Trapping the human into a very small, and soon to be very humid, space with your musk.
Giving your prospective lover no respite, you lean forward; reaching past him with one arm to unhook the shower head and then turn on the water with the other. This pushes your cock up along his spine until it's trapped between the two of you and your balls lightly press against his buttcheeks. You feel his smaller body shaking as you practically embrace him, his breath panting and heart hammering.
"D-dude..." he whispers. You pretend not to notice as you adjust the water's temperature.
"How does this... mmm... feel?" you ask, letting the water hit him as you begin to pump your hips slightly, rubbing your horse meat over him.
"Dude, I... I don't know, this feels... really weird." He inches forward, trying to escape your cock, but there's really nowhere for him to go. "I mean... I'm not gay, I-I mean, I wasn't anyway --"
"Heh, I meant the water," you tease. You step back, your cock jerking and slapping him on the back, making him jump again. You snort in lust and laughter, and proceed to quickly rinse your body off together with his back and buttocks.
"Don't worry, I get you. But it's all right..." You pat him on the shoulder with your free hand. "You love my big horse cock, the length, the girth, the heat and weight as it presses on you. And it's okay."
"Ah!" He ducks his head, embarrassment rolling off him. You can't quite see, but you do notice his shoulders flex and jerk as his hand brushes his own erect dick and pull hurriedly away. "Well uh..."
"Don't worry!" you repeat with a smile. "I know a way to make this better for both of us..."
You'd been getting off on teasing Sean, but for both of your sakes it was time to take this to the next level. Before you were ready to plow your friend, though, he needed a few adjustments to make him comfortable and his body truly attractive to you. You step closer again, hanging the shower head back in its cradle and letting the warm water spray over you, your dick pressing into his back as you lean down to whisper in his ear.
"So, tell me, Sean..."
