This is all wrong. This Spartan stud isn't your friend, you can't accept him, but you want to. You want to run your hands through his curly locks, stroke his 11 inches of glory, and be serenaded by his rich voice. But it's also wrong, you can't do this, you need to get away. The moment of hesitation allows Andy ample time to strike. The Greek warrior bending down to rest his head against your exposed shoulder. Lips kissing the exposed skin, nipping his way up to your neck. It feels amazing, Andy must have gone over this motion before. It's almost like he is marking you. Tongue wetting the skin as his lips tighten against your flesh, sometimes even giving a playful bite as he progresses onwards. Edging closer to your head, closer to the final prize, to making you his.
You shudder, body shaking, mind full of want. Your hands hovering behind the Spartan's well-muscled back. Slowly pressing against his tough skin, moving down his magnificent form, and to his well-toned ass. It's so firm, surely well used by the other Spartans. Your stray finger slipping into his hole, the anal canal easily stretching to accommodate you. Fitting in a second finger, then a third as well. How much can this man take? He seems equipped enough to handle a monster's dick... which means surely, he can handle yours.
The idea of plowing into your friend excites you further. Andy taking a break from your shoulder and giving a few loving nips to your neck. Chin scratching against your boyish skin, breaking away from the motion to appreciate how far you have fallen. One of his own fingers returning your earlier gesture. Slipping into your hole, forcing it to spread and adapt. Your rear getting bigger as his calloused hand works in a second finger. Sculpting with his advances and emptying your mind.
"I'll train you well, my friend. Prepare you for the days to come." Speaking is difficulty, words escape you, thoughts distant. You persevere, getting out the most basic of questions. "A-aah. What do you... what preparations?" The response from him being a third finger entering into you, searching around, pushing further in. It feels good, your ass full, yet expanding to accept even more. "You're my closest friend, so I need to present you to my newest companions here. Rodger's bull cock and Mark's lupine dick will love your hole."
A minotaur and werewolf, his newest allies here, maybe even the creatures that made him into this Spartan. It excites you, the idea of Andy's arm around your shoulder, bringing you to these creatures and bending you over a rock. The bull taking the front, grabbing your new curly and ruffled hair and starting to pump into you. The werewolf claiming your ass, digging as much as he can in one thrust before his knot inflates and binds you together. Andy watching close-by, instructing you on how to best manage this position. Starting with a command of "Curve your tongue, warrior. Grind it against the bull's cock." and ending with another of "Wiggle your ass for the werewolf. Make him want to breed you, warrior."
That future is delightful, but it's not your future, you can't just become another creature of this crazy place. With the most effort you've ever given anything before, you push Andy away and sprint off deeper into the woods. Cock leaving a trail of pre, churning and groaning before your eyes as you run. Inches added to the pole, pubes cresting your lower torso. "N-no, s-stop." You reach down with some hope that it will cease the change. But instead, the simple touch of your fingers against cockhead sends you over the edge. Spraying out another orgasm so close to your first, though the load is even larger.
Even while climaxing, you keep running. Leaving pools of cum stained grass, only stopping when you hit physical exhaustion. Collapsing where grass turns to dirt and stone. Mountains ahead. Caves ahead. Maybe even shelter ahead. You look over your new enlarged length, tempted to dry off the remaining cum, but worried that the action will just lead to a third load, and more changes. You're relieved that the only changes were found in your bigger cock and wider ass, but then you look over to your left shoulder. Still wet from Andy's bites, and now covered in a cluster of hairs... or perhaps furs. You can't tell which way it is, if it's just a hairy shoulder, or the start of an animal's pelt. It's course and thick, starting only a few inches from your neck, and ending where the arm starts. The skin there is tougher as well, that one isolated spot hardy to the touch, and with a slight growth of muscle in the connecting arm. Hopefully it stays at just that, and you can get some rest in these caves.
