After thinking for a while, Tyler decides to examine the “Doll” a little more, “well... I know how you look with clothes on,” the curious little boy says, “but I am curious to see what you look like without,” so he starts to undress the “Doll”.
Jeff tries with all his might to scream or do anything to get Tyler's attention, but it is useless, 'why,' he asks himself as he watches helplessly as his little naked brother starts to undress him, 'why did I do something this stupid? What if I change back? Tyler will be traumatized for life.'
Tyler discards the T-shirt and moves to undo the Jeans, he struggles a little to get the tight jeans “unhooked” from the “Doll's” cock. Jeff can't help but mentally sigh in relief as his silicone cock is freed from it's prison. Tyler moves to undo the shoes, he slips them off of the “Doll's” feet and the socks follow, he then pulls the Jeans and Boxer Briefs off of the “Doll” and stands the now naked “Doll” upright and takes a few steps back. The boy scans the Doll from head to toe, unaware that he is checking out his own brother, “I must say,” he says, “you look pretty athletic, but your cock is nowhere close to the size of mine,” the boy grins.
'Hey... I am not THAT small,' Jeff thinks, mentally pouting, 'but... man... I never thought that yours looks so damn big. No wonder you feel proud of it.'
Tyler walks around the “Doll”, “hmm... your butt looks almost like a girl's,” he says, “firm and round. I wonder...,” Jeff is shocked when he feels tiny hands spreading his silicone butt cheeks apart. “Wow, so it looks like you actually have a hole back here for a cock to enter,” the boy says, “I am curious to how it would feel like. I would prefer you being a girl-doll, but I guess your ass comes pretty close to a pussy. Let's get you into position, I'll simply imagine pounding the ass off a girl.”
Tyler picks up the “Doll” and lies it back onto Jeff's bed on its back, “I better get dad's lube, dry silicone might feel uncomfortable on my cock,” the boy hurries out of the room to get the lube out of his dad's night stand.
Jeff is in disbelief, he is about to be fucked by his own brother, 'this can't be happening,' he thinks to himself.
Tyler returns a short while later, carrying a bottle with lube and grinning to himself, the 12-year-old stops beside the bed and opens the bottle. Tyler grins down at the “Doll”, “let’s get your tight hole nice and slick,” he says and squirts some lube onto his fingers. The boy then inserts the first finger and wriggles it about, soon a second and third finger follow.
Jeff is shocked, his little brother is fingering him, how the hell does Tyler know how to “prepare”, he must have spied on their parents for sure. The teen-turned-sex-doll can’t help but mentally moan at the pleasure those tiny fingers were giving him.
“That should do it,” Tyler says, removing his fingers, causing Jeff to mentally whimper, “now to lube my “junior” and then fun can begin,” the boy says with a grin and lick of his lips. Soon Tyler’s cock is erect and lubed, the boy crawls onto the bed and positions himself between the “Doll’s” legs. He then spreads the legs and lifts them up so that the “Doll’s” butt is slightly in the air. Tyler lines his cock to the hole, before entering he looks at the “Doll’s” face, then down at its cock, “I wish you were a girl-doll, but I guess I can manage to imagine you being a girl-doll and that your butt is the pussy, I’ll just close my eyes and let my imagination take control.” The 12-year-old closes his eyes and starts to push his hips forward, the tip of his cock pressing against the “Doll’s” hole and, thanks to the lube in its bum and on Tyler’s cock, plops in without difficulty. Tyler lets out a moan of pleasure and bites his lower lip, “d-damn… I just in-inserted the tip… of my cock and already… the pl-pleasure is extreme,” he says and continues to push in further.
The second Tyler’s head enters his silicone butt with a plop, Jeff lets out a mental loud moan, ‘f-fuck… he-he is big,’ he thinks to himself, ‘and it-it’s just the head… He… he is so much bigger th-than me! I… I never would have… im-imagined being f-fucked and… and that it w-would feel th-this good.’
Unaware that he is fucking his own brother, Tyler begins to thrust in and out, his young voice echoing through the house as he moans in pure pleasure.
