My Latina girlfriend, G, was at a beach resort with a group of friends. I knew she would be a walking temptation for other men with her sexy swimsuits revealing her perfect ass and small, cute tits. I bought her those to show her off. I also knew that she wouldn't stop at tempting guys and at flirting with them. I knew she was looking for cock. As always.

And I encourage her. I just love to see how other men want her. I'm excited to know she's eager for sex with well-endowed men and still coming back to me. I love the thrill of guessing she's getting naked for a hot stranger when she's away. Of knowing she's wet for a new cock. I feel a strange pleasure knowing that at the very precise moment I'm alone at home she is riding some big cock. That nagging knowledge of being cucked is sexually intense due to a mixture of excitement, jealousy and pride.

G usually picks handsome, muscular guys with thick thighs and big, thick cocks. Beach vacations are perfect for her hunt.

During the day, I know she is eyeing guys and seducing her pick. Usually she tells me about it and sends some sexy pictures of her outfit or even a selfie with a guy, to egg me on. In the evening, I know she's sitting in a beach bar, just in her bikini, having drinks with her day's favourite. My imagination runs wild. I know that this is the time where a guy would put his hand on her soft, sexy thigh to check out how far he can go. I know she enjoys it, encourages it and already eyes how a guy's cock is growing in his shorts.

That's the moment when I'm pouring myself a drink alone at home and feel anticipation and dread at the same time. I get impatient to receive a message which usually announces that she is on her way to somewhere to fuck him and later try and send me some pics or a video.

That is then the time I enjoy most. The radio silence during which things happen at her end and I have to wait. I image her undressing in a hotel room for a man I have never seen, but am sure is her favourite type, in his thirties, vigourous, strong with a thick cock. A bull. Masculine, admirable, threatening. A man who will enjoy her body, her mouth, her pussy, just take her and enjoy her, while I'm pathetically sitting at home imagining the scenes with a hapless hard-on.

That is the time when I usually start playing with my own cuckold penis, knowing she's cheating on me, moaning under someone else's thrusts or sucking a stiff new cock.

That night, knowing she had been on the beach and that several men were with her in a bar, I was eagerly waiting for her usual text announcing she was on the way to a sex date.

Around 11 pm, she videocalled me, clad just in lingerie and said, "I'm with Carlos, he's going to fuck me, watch us darling, but don't talk, he doesn't know I put us on videocall, he'll be out of the bathroom now - enjoy the show!"

I was not really surprised as she had mentioned that one of her exes was in the group, that Carlos. It made me more jealous and more excited. Getting cuckolded live on screen by her handsome ex - that was truly humiliating and agonising, but also exciting as I got to secretly watch him taking her.

I knew they all had booked double rooms, she stayed with a girlfriend and Carlos must be staying with another guy. But now they were alone, apparently in Carlos' room and through the screen I saw G sitting down on the bed, smirking at me, sexily posing in black lingerie I had bought for her. She was so hot and so naughty!

She was looking at her phone at me with an expression that read, "What are you waiting for?"

I duly undressed to get naked to watch them and rub my cuckold cock for her extra excitement during her affair with Carlos. She smiled approvingly at me as my cock was already getting hard in anticipation. She couldn't talk so as not to arouse Carlos' suspicion, but she clearly wanted to see me masturbating while she had all the fun with her bull.

I made myself comfortable on a chair and watched as Carlos came out of the bathroom naked with his penis already erect. He went straight over to G and kissed her with his cock touching her breasts as she sat on the bed.

I felt a tinge of jealousy as they kissed, but my excitement was stronger. My penis was swelling quickly as Carlos kissed G and pushed her down on the bed. He moved to suck her breasts and she started moaning. She was clearly eager to being made love to by her ex. She had often told me that they always had had great sex.

Carlos buried his head between her open thighs - he knew she loved oral sex as a starter. She really got going, moaning with delight. My cock was rock hard from a mixture of excitement and humiliation at secretly witnessing my gf's pleasure from another man.

I recognised the sound of her cumming... she had a first orgasm so quickly! Carlos clearly knew her hotspots... he obviously also knew she had orgasmed. He looked at her with a grin and moved on top of her. I saw his big, thick cock, stiff and pointing up over his big balls. A real bull!

He shoved his massive member into G's pussy - it went in like a hot knife into butter - she must have been dripping wet waiting for his iron rod.

He didn't waste time, he must have craved her like she craved him - he pumped her frantically - I saw his thick, stiff member moving to and fro, almost completely out and then plunging all the way in. His shaft filled her pussy to the hilt. And I was sitting at home, with a pathetic erection as I watched my girlfriend having sex.

G was screaming with pleasure at each powerful thrust and I was simultaneously shivering from stroking my cuckold penis at the same rhythm as the bull was pounding G's pussy. When I heard and saw her cumming again my pitiful penis shot a big load of cum not into G's quivering pussy - that belonged to Carlos at that moment—but on my belly. Some of it was running down my masturbated erection and empty balls. I continued watching Carlos masterfully pleasing my gf.

He pulled his big cock out of her pussy, proud that he had made her cum. Now he went for the grand finale. He turned G on her belly and knelt triumphantly over her with his manhood powerfully swollen, ready for more. My penis was now shrivelling and softly resting on my cum-covered balls.

I heard G saying, "Amor, you remember what I like?"

"Yes, baby, of course...and you know I love to cum in your tight ass."

Goodness, Carlos was going to do her anal! I had always thought that she had reserved that specialty for me. How could I be so stupid, I thought, she always liked anal sex and most of the times squirted and came heavily... of course she must have done it with other men! But there I was, for the first time witnessing it on screen.

Carlos pushed his stiff cock up her ass, gently at first, until she moaned with pleasure. Then he started moving faster and I was looking straight into G's face as he pounded her. She was ecstatic and screaming with delight.

"Oh amor, yesssss, give it to me, oh yess, yess, yess!"

Carlos was pumping powerfully and also moaning. He roared, "Yeah, baby, you're my slut! You missed that, right?"

"Oh yes, your cock is the best, give it to me, oh gosh, I'm almost there, go on!"

Carlos now moved into overdrive, G was screaming and cumming hard and Carlos finished with a big grunt as he was pumping G's ass full with his bull's semen.

I looked on, my penis again stiffened from the exciting scene. Carlos had collapsed on her and G was now looking at me with a happy, a bit commiserating smile as I started striking my semi-hard cock and brought it to another erection under her satisfied look. I felt the true delight of the cuckold consumating his pride and humiliation as I jerked off my cock in front of the camera.

G watched me cum as she wiggled her ass under Carlos' weight to remind me that her real pleasure was elsewhere. My liquid semen was still running down my cuckold cock when the two kissed. Carlos got up and went for the shower.

G looked at the camera and whispered, "I hope you enjoyed the show, darling. It felt so good to have him, and knowing you were watching was nice, too."

She blew me a kiss, but then turned her head, startled by something.

Then I saw another guy walking in. Carlos' roommate probably. He was tall, with his half-unbuttoned shirt revealing a broad, hairy chest. The guy stopped in his heels as he saw G naked, looking at him. Then he smiled, and G smiled back. She stood up and I got a great view of her cum dripping ass. The man approached her and they talked, inaudible to me, but I saw his right hand patting her buttock.

She let herself be drawn towards him as he bent down to kiss her and explore her hot, naked body with his big hands.

I was electrified. G was such a slut! The guy dropped his shorts and a short but very thick penis popped up, hard and eager. He pressed it against her belly as he stole another kiss, then lifted G up and drove his thick rod up her lubricated cunt. She gasped with surprise and delight, sitting with her cum covered ass on his big hands, bouncing on his monster cock. He rocked her up and down as she clasped his neck.

I watched his penis, at least twice the girth as mine, slide in and out of G's squirting pussy. She was in heaven, cumming loudly on that stranger's massive manhood.

Mine was throbbing again, painfully aware of its uselessness in G's moment of pleasure. I saw Carlos watching from the bathroom door with his cock erect. He joined his roommate, sandwiching G between two handsome bulls, satisfying their wanton lust. His roommate literally handed her over to Carlos, who bedded her and frantically pumped her already cum-filled pussy with his stiff red rod, emptying his balls a second time.

That's when G's phone battery went dead. I was left imagining the rest of the night, knowing I would get a text the next day at lunchtime at the earliest. Agonising but exhilarated, content I had cum twice watching my humiliation enacted live on camera, I fell asleep.
