You're furious at Kevin, he screwed up and now you could both become Irish because of it. You tell him your order, he goes outside and distracts the man, you find the key and leave. If he somehow avoids becoming Irish, he can join you. Otherwise, he can get fucked and stay in this city. You can tell that Kevin is terrified of your proposal, but he holds himself and walks out of the room. You hear an Irish cheer and then Kevin's yelling... Following by loud moans and pants.
You take this as your chance to look for the key, you've got to find it before they finish up and check back here. You search for a good 10 minutes, keeping an ear out. You eventually spot the key taped underneath a shelf, you grab it and hear a loud moan, followed by an Irish voice saying "Hehehe, clean me off you needy fuck, then we're going to check this place one last time, then get drinks." Determining that Kevin is gone you unlock the back door and exit, locking it behind you as you enter the back alley.
The back alley is tight, you spot two grate fences, one on either side of you. You'll have to climb one of these fences to get to the main street. Walking to the right fence, you grab the grating and begin to climb. But your ascent is stopped as you are pulled backwards and land on the hard floor. Your head is dizzy for a moment, but you roll to your side and see an Irishman on the floor. His hair is ginger and in a short buzz cut, his facial hair very well kept. He looks at you and begs "Please, don't leave me 'ere. I don't want to turn Irish, I don't want uhh." You look at his body and notice that his chest hair is still black, or rather was. As you stare it begins to change to red. You can't be near this guy, he's dangerous. You take another leap over the fence and leave him, as you're walking away you hear a yell.
"OI, YOU AIN'T LEAVIN ME. IF I TURN, YOU TURN!" You turn around and see the man is masturbating rapidly, he moans as he holds his cock and aims it through the fence. In a yell his seed shoots at you, before you can react you feel the sticky substance on your face, the musky smell causing you to moan as your dick rises to erection. You begin to strip, your mind feeling distant. As you strip you hear the sound of the grate moving, you see the man from before in front of you. He helps you to your feet and looks you straight in the eye, his voice has deepened from before and his accent more prominent. "We're both turning now, no getting out, so let's enjoy it." You see his chest hair is fully red.
He looks at his own body, then to yours. "I want us to turn together, so let me help you catch up first." You see him stroke his cock as more seed pours out, he rubs it in your hair and chest. Your hair becomes like his, a uniform buzz cut. Though you gain no facial hair. Your chest as well changes, you gain an athletic build as your hair turns red. The man smiles as he sees this "We're at the same spot now, so ass in the air and we'll turn Irish together." You comply and kneel on the ground, lifting your ass in the air for him to see. He admires it for a second, before putting his 7-inch circumcised cock into you.
His cock barely fits in you, each thrust is painful and stretches your body. You moan and yell from this pain, but eventually, you start feeling strange. The man's cock feels foreign, yet welcomed. Your ass shapes itself around his cock, which itself is changing. You can feel skin regrow on the cock head, and the thrusts feel deeper and deeper. As his cock grows, your ass changes to accommodate it, you smile as he stuffs his now 9-inch uncircumcised dick in you and cums. It's a perfect fit.
He exits you panting, you stand and turn to him and see he now has his ass in the air. You look at your dick, it's 7-inches and circumcised. You need to change that, and change his ass. You thrust into the man as he yells from the shock and pain, a wicked grin on your face as you know he'll not be in pain for long. You thrust and thrust and feel your cock begin to expand. You gain a few inches and feel the foreskin regrowing, you're half tempted to exit his ass and play with the foreskin, but you know you need to finish the job. You thrust harder and harder, your pubes tickling his ass, as you yell out in victory.
You help your fellow soldier to his feet, the two of you bumping your chests together in a show of comradery. You two walk together, looking for the commander, as you walk your friend introduces himself. "By the way, names Traigh." You tell Traigh that you're Rorke, and you're looking forward to getting to know each other better, over a few drinks of course.
You were too slow escaping and got caught by a desperate transforming man, Traigh. After becoming infected the pleasure became too much and you submitted to him. The two of you transformed into soldiers for the new Irish army, you reported to your commander and joined the squad. Your squad defends the city from outside armies and forces, you are super soldiers, who's weapons are their strong dicks. Armies were felled by forced transformation, and each felled army added new troops who needed to be broken in by thick dicks...
