Chris lunged forward first kneeing you in the balls and then when you were doubling over in pain hitting you with an uppercut that knocked you out cold. You don’t know how long you were out; you started to come to slowly. Your eyes opened and you attempted to take stock of your situation. You were lying on your back in your bed, with Chris looking down at you with a sick grin.
“Holy shit,” he says with his eyes never leaving your body. You struggle to get up but your arms and legs have been tied to the corners of the bedframe. “Wha what are you doing to me?” you say weakly, still woozy from being knocked out. Your voice didn’t sound like yours, or even Chris’. You look up at your right wrist trying to get it free, its slender and elegant, the fingers are long and painted pink. You raise your head and look down at your body. You now have two large breasts on your chest blocking your view down your stomach.
Chris speaks again, “I don’t know who you really are, hell maybe you are my bitch younger brother trying to finally see what a real man is like” He stands up and moves from the foot of the bed to your side stopping at waist level. “When you said magic socks, I have to admit I thought you were full of shit,” he continued, “but there you were unconscious and all so I figured it wouldn’t hurt to try them out on you.”
“What have you done?” you ask with all of your strength. Your voice is familiar, and all of a sudden you remember from where. Chris had found the sandals in your closet. Lindsay was the most popular senior girl in school. You saw her leave them behind at lake a few weeks ago and you kept them. Your plan had been to give them back to her and use it as an icebreaker to talk to her. Instead you had been too afraid and now there they had sat as a reminder of how much of a wuss you were. You didn’t have a lot of time to worry about that now, Chris had put his hand on your inner thigh and was sliding it up. His thick fingers hit the lips of your new vagina and stopped. You shuttered with a mix of fear and revulsion. Your brother was now playing with your genitals.
“I remember this chick from high school” Chris spoke to no one in particular, “ she was a few years younger than me, never got a chance to do her” He pulled his hand away from your pussy and smelt his fingers, before licking them. Chris took off his shirt and pants, leaving himself in just his briefs. His massive erection was obvious, pushing out of the fabric . You start to struggle again, forcing your hands and feet against the restraints. Your new body was weaker than Chris’s or even yours. Chris moved quickly to stop you, getting on top of you. You couldn’t resist against the weight and strength of his body. His took a deep breath, nervous for what was going to come next.
“Chris please don’t do this” You plead, “I’m I’m your brother.” He reached down and worked his underwear off, taking care to rest his enormous hard cock right on your little pussy. You were really scared now. “Maybe you are, Maybe you aren’t” he whispered, “right now all I see is a pretty girl who’s about to take a pounding.” Chris raised his hips sot the tip of his penis dipped and then began working it into you.
He is so big at first there was nothing but pain. After a few thrusts, you started to get wet and he slid in with a bit more ease. Chris keeps pumping, until as much of him as can fit inside your tiny box is in. Any enjoyment that you might have taken from this experience is tempered by the fact that you are looking your older brother in the face as he repeatedly thrusts into you. After about 30 minutes you can tell he’s almost done, his pace has quickened, he’s moaning louder (moans you remember making in the shower), and finally his hips pulse and you can feel his dick spasm inside you, releasing a thick river of cum. He pulls out and lets the second and third rope go all over your now significantly looser vagina. Chris hops off and without even looking back at you, leaves the room and heads to the bathroom for a shower. You hear the water start running and...
