You rush over to the sink, staring yourself down in the mirror. Hairs still the same, face still the same, body still the same. Whatever drink you were given hasn't taken full effect yet. But how long until you change like that other guy, 'James'. You saw him go from shrimp to stud in the span of a minute. You could suffer the same fate as him if you don't figure something out. Though it's so hard to concentrate. Both because of the pressure, and because of the rising sound of singing from the bar next door.
'Is early in the mornin' so let's get pissed! From bar to bar we'll drink this shit!'
It's a catchy, infectious melody that rots your mind as you hear each word. The voice of James recognizable with the rest. A true Irishman, celebrating St Patrick's Day with the lads. They're all having so much fun, the whole town probably is by now. So, if everyone's better off with a bit of green, why shouldn't you be? You look at yourself in the mirror one more time, saying good riddance to the old you as your hand grips the top of your cock.
There's not a single shred of shame in your body as you jack yourself off in this public bathroom. Just an anticipation and eagerness to join the boys next door. A thrill to sit at the bar and get your first drink! You continue to stroke your average cock, coaxing out the changes, and the spread of ginger hairs that takes over your pubes. Each rub going from the top of your shaft all the way to your pubes, getting longer and longer each time. Manhood expanding, cum leaking onto the sink's bench. You're probably a shooter, and that's something to be proud of.
'Feelin' around and havin' a rub. Let's see this lad's chub.
Their song continues, and likely takes an intimate turn. You just want to get in there, help your fellow kin relieve themselves on this special day. Your right hand continues to jerk yourself off, your sleeve straining and ripping as your arm bulks up with each pump. Well-muscled and defined, red hairs under your pit, and across the back of your hand. Your left hand moving over to give a feel for these new gains you've gotten from this little exercise. Tracing up the wave of change as your shirt continues to break apart. Right pec a plate of might and left quickly following. Dense hairs growing in-between them, a bright ginger that spreads down towards your pubes.
You haven't stopped masturbating for even a second, feeling like you're at the edge of climax, and loving every second of it. These changes keeping you on the precipice of pleasure, yet it still seems to rise. Your free arm getting a feel for your new self, before ballooning on its own. Joining with the rest of your upper half as you look at your new chest with pride. You're big, strong, and one step closer to getting a drink in your hands and an ass for your cock.
'Look for a hole and make it fit. No one's sayin' no so don't you quit!'
Their mind is the same as yours. Moans now amongst the rhymes, your own unchanged voice somewhat joining with their music. A gasp of pleasure escaping your lips as your back curves and thins, defining, and making your ass nice and tight. Ready to be ploughed by one of your drunk friends, while your leaky cock finally stops growing at 11 inches of glory. Just the size to really dig into one of your mates. As your pants creak and fall to the same fate as your shirt, your legs tighten and surge with power to support your new and heavy form. Filled with vigor, muscled, and ready to rest besides the rear of one of the lads.
Your eyes half close as the stimulation gets even greater. But you need to keep watching, need to see the final changes. See how your puny head adapts to your goliath of a body. You've gotten stronger, taller, sexier. But you need to alter that last bit, make yourself fully Irish like the rest. Your strokes hasten as if to force out the last of your changes, and it seems to work. The stubble on your chin turning that distinct red. Adams apple pushing out, chin flattening, hair keeping itself numerous yet short. Eyes turning emerald, voice deepening, and getting that distinct accent. That same tone as your fellow Irishmen.
'Fill 'em up and move to the next. Don't you dare forget to flex!'
You join the song, words coming to you naturally as your cock empties its overstuffed balls. Coating the mirror in spunk, obscuring your reflection, excluding your own head. The new image of a cocky and young Irishman grinning at you. This is the new you, and you love every bit of it. Your gaze turning down to look at the rest of your changes. Your sexy body, strong legs, and still erect cock. Looks like it's time for your first drink!
You leave your shredded clothes behind, and head into the bar next door. It stinks of ale, sex, and you love everything about that. Seeing your fellows with beer in hand, and cocks being attended. Some thrusting them into the mouths of their mates. Others taking up a friends offer to fill their ass. A few more rutting against each other. You can't wait for your own fun, being passed a beer, and having a meaty hand squeeze your dick. Fuck it feels good to have one of the lads help you out. Your eyes turning to see who did it, and spotting the familiar guise of James.
"Finally, was waitin' for ya to join in."
His thumb rubs against your pole. Despite having cum just before, you're ready to go again.
"Couldn't say no to this party."
You answer with pure honesty. Truly, you couldn't. You're so happy to have joined these men. Transformed just like the rest, and living up the festivities. James giving you another stroke, then pulling you into a hungry kiss. Spreading that delicious taste of beer with his own wanting tongue.
"Then let's have some fun, aye? Share the party a bit with the wankers outside after."
You give James's ass a hard smack. Squeezing the firmly muscled rump and giving a cheeky grin in response.
