He invites me out on the boat with his older family members, I let them fuck me while he watches helplessly

This is another fantasy I've had for a while. A while ago one of the guys in my friend group had a huge crush on me that lasted a while and kept asking me to come out on his dads boat with them. I wasn't into him and made sure I turned him down gently but right around that time I discovered cuck porn, and that lead me to porn on boats and this fantasy. It was the first cuck fantasy I ever touched myself to, and a few guys have asked me about cuck stuff which has got me thinking about it again. (Sorry David!)

In the fantasy, I arrive at the dock by myself. My parents have met his, so there's no concern there. I've met Davids dad James before, and honestly always secretly found him more appealing than David himself; he looks similar in a way I guess, but in a way David would obviously never match. He's not just bigger, he also has the look of a lifelong outdoors man who never avoids hard work, with a thick neck, barrel chest, big arms, and a weathered but tough face. His hair is short and dark, flecked with grey.

I didn't plan on going in the river, so I'm just wearing shorts and a tee, but I can't help but blush as I see the men eyeing my figure.

I'm surprised to see its not just David and his dad there, but the other men of his family. His uncle John and grandfather Jack quickly introduce themselves, and I realise they all have his fathers build, but his uncles head is shaved bald and his grandfathers hair is all grey. I know David idolises them, but my poor chubby friend just doesn't have the same appeal as these rough looking outdoorsmen.

We set off, and the men quickly break out the alcohol. I don't usually drink, but I don't want to be the only one sober so as the boat heads out to sea, we each grab one and start drinking. As we relax around each other the jokes start. At first I'm shy, and they laugh at me blushing at their inappropriate jokes. But eager to impress, soon I'm joining in and making double entendres and laughing along with them. David looks more and more uncomfortable as they start complimenting me.

The drinks keep flowing and by the time they suggest we swim, I'm feeling too good from the wine and compliments to care that I didn't bring my swimmers. They stop the boat and I strip down to my underwear, blushing but secretly loving the attention as the older men whistle. David suggests I leave my clothes on, and he's chastised by his dad for being a prude.

David stays sulking in the boat as the men and I splash around in the ocean, laughing as they keep swimming by behind me to grab my butt.

When its time to get out of the water, I decide its time for another layer of sun screen, and the men volunteer to help me apply it. David goes to the front of the boat, still sulking, as James stands behind me. I feel his big bulge pressed against my back as his huge hands slide over my body, sliding up my back, down my sides, up my front. I lean back into him, and David tries telling his dad that's enough, but we ignore him. Jack points out we've missed some parts, and I reach around behind myself to undo my bra.

James reaches around me, his hands covering my boobs, squeezing my nipples between his big thick fingers as the men continue to praise my body.

They suggest I put sunscreen on them, surrounding me, and turn around between them, my hands touching their muscles as David continues to complain, the men's hands roaming my body as they lean close, kissing my mouth, my neck, and even leaning down to kiss my boobs.

I sink down to my knees, my hands reaching out to take their thick dicks out of their shorts. They tell me how hot I am as I look up at them towering over me. They crowd around closer as I wrap my mouth around James' shaft, eagerly sucking each of the men in turn, going from one to another with my mouth while jerking the others off with my free hands. The men moan loudly, their hands tangling in my hair as they take turns forcefully fucking my mouth. Then they pull out, jerking off in my face, and all cum at the same time, covering my face with sperm and dripping down onto my boobs.

The men hold me between them, tossing me like a ragdoll, lowering me onto Jacks cock while John and James take my pussy and mouth.

The men gangbang me for hours, all different positions, spitroasting and DPing me, Dwight watching with tears in his eyes. When its all over and I'm lying there, cum all over my body and dripping from my sore stretched ass and pussy, David walks over to me, nervously rubbing his dick through his pants. I tell him sorry, but I'm too tired for more. Then I crawl onto James lap, and lower myself onto his dick.
