Day Two in my Sister's Body Pt. 01

Waking up with a start in bed can be disorienting, waking up with a start in a beanbag in the attic surrounded by stacks of books is painful. My leg kicked out reflexively which resulted in a stack of diaries tumbling down on top of me, hurting a lot more than it would in my normal body, especially as one corner of a book landed directly on my still tender nipple causing me to yelp. Digging my way to freedom with one hand and nursing my bruised tit with the other, I managed to get free and start working my way downstairs. The pain in my chest brought flashes of memory, Mike biting down on my nipple as he pounded into me under the sink, the cracking sound as his hand found my ass and the feeling of fullness as he rode me from behind. I can't deny it felt fucking amazing but it also makes my feel gross thinking of Mike's creepy leering and groping, his abuse of my body and the way he talked to me. In the moment I couldn't get enough, it was like a desperate need had taken over my body, hence last night's study.

I knew the longer you spent in a body the more it starts to rewrite your brain a little but nobody had ever prepared me for that, so after searching through the diaries and journals I think I found the cause. A few passages and stories mention a side-effect of switching bodies, getting cum inside you turns your body heat and horniness up to 11 and it can take hours to wear off. It's stronger in some bodies but the end result is usually a cock hungry slut who will do anything to be sated. That left the little matter of how I managed to get cum inside me and on reflection the turning point was the lemonade, I thought Mike had just slipped some vodka in but he must have mixed in some cum and used the vodka to mask the taste.

The idea makes me want to vomit in my mouth.

My stomach rumbled at me as if in response, time to grab some breakfast and figure out how to wipe my memory.

A few slices of toast and cup of coffee go down nicely but after yesterday I really need a pick-me-up and in my own body the gym has always been my go-to for a bad day. Lift some weights to lift the mood and considering I promised Kim I'd keep up her exercise schedule it's a two birds situation. This time of day it should be pretty quiet, less chance of having to make up excuses to someone Kim knows why she's acting so differently.

Back to Kim's room and at least she left her workout gear in an easy to find pile, a pair of pink yoga shorts and a white sports-bra that showed a little cleavage. Finding a pair of underwear to go with them was a problem, her drawers only full of lingerie and thongs and I can't imagine trying to do a workout while getting my ass flossed by fabric. It wouldn't be the first time I've gone to the gym commando in dire situations and girls have less junk flopping around that needs hiding so I guess that's that decision made.

Pulling up the yoga shorts snug against my ass, I'm really starting to understand why women wear these. As a guy you think it's just to show off their body(and looking into the full length mirror in Kim's room, wow what an ass) but they're also ridiculously comfortable, even when it feels like it's riding up my ass the fabric is so silky soft it's not uncomfortable. After how easy it is to pull the sports bra over my head and adjust my tits I might have to wear one of these every day this week, much easier than playing with strings or hooks. It's another hot day so a jacket isn't needed but in lieu of anywhere else to put my phone, money and earbuds I pull on a cropped hoody and head out the door

One of the downsides of being in Kim's body is she never got her drivers license and I can't risk getting pulled over and getting her in trouble, that means I'm stuck with public transport. It's not too bad, the bus to town stops near the house and the next stop isn't far from the gym so that gives me a chance to stick on some music and zone out for a while.

There's only a few people waiting for the next bus when I arrive, an old lady and her carrier bag on wheels, three teen girls that looked to be giggling over a text conversation and a dude with his hands in his pockets who looked like he was trying to be subtle about staring, gross. As I walked up the dude turned to look over and there was a flash of something weird in his eyes, surprise for a few seconds then a little cocky grin as his eyes start roaming my body hungrily. He seems like a bit of a weirdo but looks like he recognises me so he could be someone Kim knows, just in case I give him a quick smile and turn back to my music. I didn't realise you could feel someone's eyes on your ass before, like a heat ray boring into my cheeks but thankfully the bus turned the corner and came into view.

As it pulls up to the stop all I can do is grimace, it's almost completely full already. Piling in there's only standing room available and not much at that, being one of the last on I was standing by one of the teens who got separated from the others and noticed the only standing spots were beside the old lady or on top of the leery dude. I locked eyes with her for a second and decided to take one for the team, shuffling past her as she mouthed a silent "thank you" to take my place in front of him. An older man kindly moved over slightly to give me access to a handhold which is very appreciated in this shorter body, the downside being it left me basically surrounded by people's backs on all sides. The bus took off with a shudder, with my one arm raised above my head lifting my perky chest this caused my cleavage to shake which is a very strange sensation, I expected the sports bra to lock them in tighter. As I mused about my tits and looked up at my hand to readjust on the handhold my eyes locked on the man behind me who must have been craning his neck to look down my top, when he finally noticed me looking at him he just gave a leering grin. I guess this is just something women have to get used to, when she gets home I'm gonna have to demand Kim finally gets her license.

The first few minutes of the bus ride were mostly uneventful, packed in like sardines all I can do as the bus rounds corners is let the wave of bodies move me around, my left arm clinging to the handhold and the other pinned against my side almost behind me. After a couple turns we settled onto a long straight and I can feel the guy behind me start pressing against my backside. The shuddering of the old bus was making my curvy ass wobble into his crotch and his growing hard-on was starting to force my yoga shorts further up into my ass as the tip of his hardening cock started to fill the tiny amount of space between us. My lack of underwear is gonna be a serious problem soon with only the thin fabric of my shorts and his own pants keeping his dick from rubbing against my asshole.

"I have to stop this creep soon at this rate he'll burst a hole in my shorts, or bust a load on them" I thought. Without even room to turn around the only option I can think of is to move my trapped right hand behind me, an additional barrier between him and my ass. This seemed like a great idea, for all of about 5 seconds before he started pumping his dick directly into my open hand. Now it feels more like I'm giving him a handjob through his pants, I don't know if that's better or worse than risking him leaving a stain all over me. I tried to twist my neck to give him a look to stop but as I turned I could feel his breath in my ear, he had bent down himself. "I knew you were a dirty girl the moment I saw those massive tits but I didn't think you'd be so desperate to grab my cock" he breathed, barely above a whisper and with the roar of the bus engine there was no chance anyone else could hear. I tried to turn a bit further to tell him to fuck off but as I did he shoved his tongue into my mouth!

It was just a quick moment, a flash of a kiss, his tongue desperately probing and ended after an instant but the shock left me speechless. How brazen do you have to be! I looked around the bus to see if anyone had seen but everyone else either had their heads down or forward, off in their own worlds. I locked eyes with one man who had been people watching but he just turned a shade of embarressed red and turned his head back to face forward and mind his own business. In my frozen shock I didn't notice the man behind me shuffling, rearranging something until the warmth of his cock hit the palm of my hand. This guy is shameless, he's just unzipped his dick and dropped it into my open hand. The warmth wasn't the only thing I noticed, he wasn't the most endowed but as it rested on my fingers the girth shocked me, this guy had a seriously fat dick.

My shock finally wore off and as reality started to settle in again I tried to shift my hand out of the way again but the man behind my locked onto my wrist like a vice. Between his strength and my arm being trapped behind me I had no leverage to pull away, his grip on my wrist forcing my fingers closed around his rod. "Be a good little quiet girl and I've got a present for you I'm sure you'll love" he whispered into my ear as he started pumping his hips while the hand gripping my wrist started pumping in rhythm, using my hand to wank his rock hard cock. At this point I can already feel the pulsing veins in his dick, the heat of it and his breathing in my ear start to get ragged, all signs he's already nearly ready to burst so all I can do is close my eyes and wait for it to be over. I can feel his free hand move to my hip and start to snake under my cropped hoody which was zipped up, hiding the hand that slipped up and under my sports bra and began gripping my left breast, pinching and rolling the nipple between his fingers.

Between his hot breath and the nipple play it was starting to get to me and I could feel wetness starting to form in my pussy. I'd seen porn of these train molesters, videos and hentai before and I admit I had found it hot in a taboo way. I would never be that guy myself but to be on the recieving end was never something I expected let alone be something that would feel so hot. My own chest started to rise and fall a bit quicker into the strangers hand as he started to grab more, more tightly and desperately while his breathing became ragged. "I might as well help this end quicker, we can't be far from the bus stop" I thought as I took the initiative, gripping his cock tighter and starting to pump it myself. He removed his hand from my wrist when he noticed I was doing the work for him and his right hand made it's way up under my hoody and onto my other tit, nothing sensual or delicate about it now just desperate needing and groping. I could feel him close now but up ahead I could just about make out the stop coming up, fuck I can't get caught like this I'm dripping wet and panting nobody would believe this guy was molesting me and I wasn't in on it, I'd get Kim's body done for public indecency. I need him to finish and quickly, so I turned my head and latched onto his lips, tongue parting them and diving into his mouth. His eyes opened in surprise and a moan escaped into my mouth but the shock seemed to tip him over the edge, I could feel the eruption of cum starting. The first few shots blasted right into my exposed lower back before I managed to get my hand in front of it and catch as much as I could. He moaned into me as the last few spurts shot into my palm and stickied my fingers. I wiped some onto his own shirt as our lips parted and he started to catch his breath but could feel the jizz on my back start to drip down into my waistband. I swiped up the heavy load onto my fingers as the bus started to slow to pull into the stop.

People started to shift in preperation of getting off and I was able to get my right hand free and pulled it back up in front of me, my wrist and forearm were a bit sore from being trapped for so long so I took my hand off the handhold to rub my pained arm in front of me. As I did so, the man behind me removed his hands from my tits but instead of pulling them away, he grabbed my right hand and pulled it up into my face, pushing my cum covered fingers into my mouth! "I told you you'd love my present" he said as my eyes shot open in shock, his cum making it's way down my throat. He held me there for a moment as the bus shuddered to a stop and people started pushing their way to the front. He led me forward like that until we were near the front then released me, smacking my ass as he pushed me off the bus. I stood there at the bus stop for a second breathing heavily as the bus started to take off and I could see the man hadn't left, he took a now free seat near the window and grinned as the bus took off leaving me dumbfounded.

"Fuck, how did I let myself get dosed with cum" I thought, as I could already feel the heat starting to rise within me. "This is gonna be rough but the next bus home isn't for ages. Maybe I can burn off the need in the gym, distract myself until I get home then fuck myself silly on Kim's vibrator." Even the thought of it made my nipples harden again. It was going to be a rough workout...
