Iād lived alone in my flat in Madrid for almost eight years. It was a beautiful bachelor pad ā high ceilings, big windows overlooking the city, a sleek modern kitchen I barely used, and a rooftop terrace perfect for evening drinks. At 45, I had a good life. Successful job, nice things, plenty of freedom. But lately the place had started to feel too quiet. Too empty.
So I signed up to host an exchange student. Why not? I figured it would be nice to have some energy in the house again. Give a young college kid a proper Madrid experience.
The agency matched me with Mark Rossi.
Nineteen years old. Columbia University. Italian-American from New York (real Italian though, like his parents were from Turin). When his profile photo popped up, I actually paused. He was ridiculously good-looking in that effortless, boy-next-door way ā warm brown eyes, thick dark hair that fell a little messy, a bright smile, and smooth, tanned skin that suggested he spent time outside. He looked innocent, almost sweet. But when we video-called, his personality came through immediately: confident, frat-bro energy mixed with that natural Italian charm. Funny, outgoing, quick with the jokes, but polite and respectful.
He arrived on a warm September afternoon.
I opened the door and there he was, rolling a big suitcase behind him, backpack slung over one shoulder. He was even better looking in person ā about 5'11", athletic build, wearing a tight Columbia t-shirt that showed off nice arms and a broad chest, and a pair of shorts that revealed strong legs.
āJuan! Man, itās so good to finally meet you,ā he said with a big grin, stepping forward to give me a firm handshake that turned into a quick bro hug. āThis place is insane. Thank you again for letting me stay here.ā
We clicked right away. Within the first few days, it felt like weād known each other longer than we had. Mark was easy to live with. He helped cook, kept his stuff organized, and had this infectious energy that filled up the flat. Weād sit on the terrace drinking wine in the evenings, talking about everything ā his classes at the university in Madrid, life in New York, my travels, girls heād dated, the crazy parties he went to. He had that perfect mix: American warmth and humor with a European confidence and flirtiness that made him magnetic.
I was getting used to having someone else around. Enjoying it, even.
Then, about ten days after he moved in, something weird started to happen.
At first I was really confused.
I woke up in the middle of the night, heart racing for no reason. I could have sworn I was in one of the guest beds. The mattress felt different under me, the layout of the room slightly off in the dark. But that didnāt make any sense. I always slept in my own room. I rolled over, mutter to myself, and fall back asleep. When I woke up, I was in my room still.
A few nights later it happened again. This time I woke up convinced I wasnāt in my own bed. The sheets felt wrong. The pillows were different. I blinked into the darkness, confused, before sleep pulled me under again.
Then, a few nights after that, I woke up drenched in sweat. My heart was pounding hard. I reached up instinctively and ran my hand over my bare chest.
Where the hell was all my chest hair? Where was the thin gold necklace Iād worn every night for fifteen years? My fingers kept moving across the unfamiliar flat, toned skin, searching for something that wasnāt there. Panic flickered in my chest, but before I could fully process it, exhaustion won and I drifted off again.
The next time it happened, I woke up properly.
I sat up in bed, disoriented, I was definitely in one of the guest rooms. I stumbled over to the mirror on the wall. The streetlights outside cast just enough glow for me to see my reflection.
His handsome, boyish face. His messy dark hair. His smooth, athletic torso. I was in Markās body.
I froze, eyes wide. My ā his ā hands flew up to touch my face, my jaw, my chest. This wasnāt a dream. I could feel everything. The lighter weight of his frame, the absence of my usual bulk, the way his cock sat differently in the loose boxer briefs I was wearing.
āWhat the fuckā¦ā I whispered in Markās voice.
A strange mix of panic and arousal hit me all at once. I was freaked out, heart hammering, but I also couldnāt ignore the low throb of excitement looking at Markās reflection ā my reflection right now. I looked good. Really fucking good.
I stumbled back to the bed and lay down, staring at the ceiling, breathing hard. Eventually I must have passed out again.
When I woke up the next morning, I was back in my own body. In my own room. The familiar weight, the chest hair, the necklace against my skin. Everything was normal.
Mark was already in the kitchen making coffee like nothing had happened. He looked up when I walked in and gave me his usual bright smile.
āMorning, Juan. You sleep okay? You look a little tired, man.ā
I stared at him for a second, searching his face for any sign that he knew.
āYeah,ā I said finally, forcing a casual tone. āSlept fine.ā
He nodded, none the wiser, and slid a mug of coffee toward me across the counter.
I took it, my hand slightly unsteady.
Whatever the hell was going on⦠Mark didnāt seem to have any idea it had even happened.
The next night I went to bed with a strange idea in my head.
As I laid there in the dark, staring at the ceiling, I thought about Mark. About his body. His face. His energy. I focused hard, willing it to happen again. I didnāt know if it would work, but I tried anyway.
A few hours later, I woke up.
The room felt different. The bed felt different. I sat up slowly and looked down at my hands ā younger, smoother, with a light dusting of dark hair on the forearms. I touched my face. Sharp jaw, no stubble yet, thick messy hair falling over my forehead.
I was in Markās body again.
I swung my legs over the side of the bed and stood in front of the mirror. Markās reflection stared back at me, wide-eyed. I opened my mouth and spoke.
āHoly shit⦠this is real.ā
The words came out in a clear American accent. Then, I tried again in Spanish.
āĀæQuĆ© coƱo estĆ” pasando?ā
It sounded rusty, clumsy. The words felt heavy on my tongue and came out with a strong Italian accent. I switched to Italian without thinking and the sentence flowed perfectly, natural and fluent.
āPorca puttana⦠funziona davvero.ā
I laughed in disbelief, hearing Markās lighter, younger voice. The contrast was surreal.
Over the next several nights, I started doing it on purpose. Iād lie in bed, think about Mark, focus on his body, and more often than not, I would wake up a few hours later inside him.
Some nights I would just lie there in his bed, exploring. Iād run my hands over his smooth chest and abs, feeling the lean muscle. Other nights Iād get too turned on and end up jerking off slowly in his room, watching Markās handsome face in the mirror as I stroked his cock. The orgasms felt incredible ā sharper, quicker, almost addictive.
A couple of times I even went for late-night walks in his body. It felt incredible ā young, light on my feet, full of energy.
But no matter what I did, by the time morning came I would always get overwhelmingly tired. Iād crawl back into his bed, close my eyes, and wake up back in my own heavier, older body.
Mark never said a word about it. Heād greet me cheerfully every morning, completely unaware that I had spent half the night living in his skin.
A few weeks went by like that. I kept waking up in Markās body most nights, sometimes on purpose, sometimes not. I explored, I jerked off in front of his mirror, I took late-night walks through Chueca feeling young and alive. Every morning Iād wake up back in my own heavier body, and Mark would act completely normal, like nothing strange had ever happened.
Then Pedro came to visit from Bilbao.
Pedro had been my best friend for almost fifteen years. Thirty-nine, sharp-featured, always well-dressed, with that effortless charisma that turned heads wherever he went. Iād had a crush on him for most of that time. A quiet, hopeless kind of crush. I knew I was a good-looking guy ā people told me constantly ā but Pedro had never seen me that way. Not once.
He was a bit of a fuckboy. Always chasing younger guys. Twenties, early thirties at most. It verged on problematic sometimes, but he never crossed any real lines. He just loved being worshipped by hot, eager younger men. Over the years I had pushed those feelings for him down as deep as they would go. I told myself I was over it.
The day he arrived at the flat, he dropped his bag in the hallway and gave me a big hug.
āJuanito! Fuck, itās good to see you, man.ā
Then Mark walked out of the kitchen carrying two glasses of water, wearing a tight Columbia t-shirt and shorts.
Pedroās eyes locked onto him immediately. I saw the shift in his posture, the way his gaze lingered. He tried to play it cool, aloof, but I knew him too well. He was captivated.
āPedro, this is Mark. My exchange student from New York,ā I said.
Mark flashed that bright, boyish smile and shook Pedroās hand. āNice to meet you, man. Juanās told me a lot about you.ā
They started talking, and I could see it happening right in front of me. Pedro was interested. Mark, for his part, wasnāt exactly discouraging it. He laughed at Pedroās jokes, held eye contact a little longer than necessary, and gave him that charming, slightly flirty energy. Not over the top, but enough to make Pedro work for it. It didnāt feel like a straight guy just being polite. Mark was definitely into the attention.
I felt a sharp twist of jealousy in my chest.
Here I was, a good-looking, successful 45-year-old man who had wanted Pedro for years⦠and this 19-year-old kid was getting his attention in five minutes flat. It was frustrating as hell.
That night, after we all had a few drinks on the terrace, I went to bed earlier than usual. As I drifted off, I found myself thinking about Mark again. Thinking about his body. About how Pedro had looked at him.
A few hours later, I woke up.
I was in Markās bed again. In Markās body.
I lay there in the dark for a moment, heart beating fast, already knowing what I was going to do.
The next night we all went down the street to watch the Madrid derby at a local bar. The place was loud, packed with fans, and the energy was electric. We drank a few beers, yelled at the TV, and laughed the whole time. Mark was in his element ā loud, charming, cracking jokes. Pedro couldnāt keep his eyes off him.
When we got back to the flat it was already past midnight. We kept hanging out in the living room, talking and drinking wine. Eventually I started feeling tired and headed to bed.
āNight guys,ā I said, trying to sound casual.
āNight, Juan,ā Mark replied.
Pedro just gave me a small nod, his attention clearly elsewhere.
I lay in bed for a while, staring at the ceiling. I could hear them still talking and laughing in the living room. Then the voices got quieter. Lower. More intimate. The sound of movement. A soft laugh from Mark. The unmistakable creak of the guest room door closing.
I tried to ignore it, but I couldnāt. Even with the door shut I could hear them. The low murmurs. The rustling of clothes. The quiet, wet sounds of kissing. Then the rhythmic creaking of the bed and Markās muffled moans.
I lay there listening, a painful mix of jealousy, arousal, and frustration twisting in my gut. Eventually I closed my eyes and focused hard on Mark again ā on his body, his face, the way he felt ā as I drifted off to sleep.
I woke up a few hours later.
It was 3:17 AM. I was no longer in my own bed.
I was lying on my side in the guest room, completely naked, with Pedroās warm, muscular body pressed against my back. His arm was draped heavily over my waist, his hand resting possessively on my stomach. I could feel his soft cock nestled against my ass, still slightly sticky.
My heart started racing. Pedro was spooning me tightly, breathing slow and deep in sleep. I stayed perfectly still for a moment, just feeling the heat of his body, the weight of his arm, the scratch of his beard against the back of my neck.
I needed to see all of him.
Carefully, I turned over in his arms. Pedro made a sleepy sound but didnāt wake up. Now facing him, I could finally take him in. His handsome face relaxed in sleep, the strong line of his jaw, his broad chest rising and falling, his intricate tattoos, the dark hair trailing down his stomach. His cock rested thick and heavy against his thigh.
I stared at him, drinking in every detail. This was the man Iād wanted for years. And right now, in Markās younger, tighter body, I was the one lying naked in his arms.
My cock ā Markās cock ā started to harden against Pedroās hip.
Pedro stirred, his eyes still closed but his hand sliding down my stomach until he felt how hard I ā Mark ā was.
āOh⦠seems like someoneās ready for round two,ā he murmured, voice thick with sleep and lust.
In one smooth, powerful motion he rolled onto his back and pulled me on top of him. I straddled his hips as he gripped my waist and guided me down onto his thick cock. I gasped as he slid back inside me, still slick from his load earlier. The stretch was intense.
I started riding him slowly at first, then faster, grinding down hard. Pedro pulled me forward into a deep, hungry kiss, tongue sliding into my mouth as he thrust up to meet me.
āFuck, you feel so good,ā he groaned against my lips.
He flipped me onto all fours and fucked me deep in doggy style, his hips slapping loudly against my ass. Then he pulled me up so my back was against his chest, one arm wrapped around my torso while he kissed and bit at my neck and shoulder from behind. His other hand roamed greedily over my toned abs and obliques.
āSpeak Italian for me,ā he growled, still thrusting steadily.
I moaned in Markās voice, the words coming out naturally, āTi sto scopando cosƬ bene⦠mi fai impazzireā¦ā
āSuch a good boy,ā Pedro praised, his hand stroking my cock in time with his thrusts. āSo fucking tight for me.ā
He flipped me onto my back and pushed my legs up, fucking me in missionary. His eyes locked onto mine, slack-jawed, pupils blown wide with pleasure. He looked completely lost in it, like he was drunk on how good Markās body felt.
The orgasm hit me like a freight train.
My whole body seized up. Waves of intense, shuddering pleasure crashed through me, stronger than anything Iād ever felt in my own body. My cock pulsed hard between us, shooting thick ropes of cum across my smooth chest and stomach in powerful spurts. I cried out, hole clenching rhythmically around Pedroās cock as the orgasm seemed to go on forever.
Pedroās eyes widened with raw lust. He greedily scooped up a big glob of my cum with his fingers and licked it off his hand without breaking eye contact.
āMmm⦠not bad,ā he said, voice rough. āSweet. A little salty. Tastes like a young guy should.ā
He scooped up more and brought his fingers to my lips. I hesitated for half a second, but he pushed them into my mouth anyway.
āOpen. Taste yourself,ā he ordered.
I sucked his fingers clean, tasting my own cum while he kept fucking me slow and deep.
āNot too bad for a kid whoās only tried girls before,ā Pedro said with a wicked grin. āGlad I could be the first cock to fuck that tight little ass. Next time Iām gonna pull out and shoot my whole load all over that pretty face.ā
He fucked me harder for another minute, then buried himself deep and came with a low groan, filling me again.
We collapsed together, sweaty and exhausted, and fell asleep tangled in each otherās arms.
When I woke up, sunlight was streaming through the window.
I was still curled up against Pedroās warm body. Still in Markās body.
I carefully slipped out of bed, heart racing, and snuck into the kitchen wearing only a pair of Markās boxer briefs.
As I turned the corner and looked up, I was shocked to see my old body was already sitting at the kitchen table, wearing my favorite robe, sipping coffee. He looked up at me with a calm, slightly amused expression.
āMorning,ā he said casually, in my voice.
Who's body would you want?
