What does it feel like when a guy cums in your ass?

I have a bit more of a story to tell you rather than a quick answer so im sorry in advance.. but.. i want to start by saying im not anywhere close to the cumdump slut i wish to be but there was a few times where I had hooked up with older men who had small 4-5in cocks, and many of them dont know how to edge themselves and cum wayyy to fast… and because of that their loads were usually tiny and watery, and i didnt feel anything after they would cum inside me. and after a few more attempts i was close to giving up and concluding that everything I heard about “how amazing it feels to have a cock pump his hot load inside of a bottom" and then one early morning right before work, i was leaving my shemale friends house, horny as hell cause she liked to tease me when we fucked often times not even cumming at all, she was actually the first person to have ever topped me and cum inside of me, and she was relatively small with about a 4-5in uncut cock, and also was not able to notice any difference, and after letting her cum inside me i opened up grindr as she took a shower and I was secretly browsing the men in my area and I was starting to get desperate at the desire to at last feel what every bottom always brags about and i literally just went and started sending taps and messaging EVERY profile if they were down for a quick morning fuck, letting them know that I didn't want reciprocation i just wanted to have my ass fucked before going to work, and one guy responded saying that his boyfriend had just been arrested and that he was desperately needing to fuck and release his 3 day load he had built up and that he didnt want his partner about it and wanted to be quick and meetup within the next 20min. The Slut in me after having my ass teased all night agreed so fast and next thing i knew i was on Google maps only 10min from his address, I very quickly had to make up an excuse to leave my friends house not mentioning that i was leaving to hook up with an older top with no pics or profile stats, I didn't even know what I was getting into, and finally after arriving he met me at the door, quickly guiding me into the nearest bedroom he was an attractive latino stud with a huge and thick 9in cock, bigger and anything I had ever had, and without saying a word he drops his shorts revealing his already fully erect rock hard dick holding it at the base and my instinct to get down and suck him first kicked in and i attempted to get my mouth around the head of his cock which was already all lubed up and ready to fuck his silence finally breaks guiding me to the foot of the bed telling me to bend over and that he didn't care to get his dick sucked and that he just wanted to fuck a tight white ass. And within minutes he had removed my butt plug and had me bent over the bed with my legs spread apart, hands behind my back holding me by my wrists as he waste no time to work every inch into me untill he was balls deep and rough pounding my ass, as fast and as hard as he could hitting my prostate with every thrust as i screamed and moaned in bliss which i had never felt before and i was lost in pleasure as he was in control of my body holding my arms behind my back and pushing my whole body back and forth matching his rhythm for about 5-10min before i noticed he was about to cum, we had never got to discuss anything about wearing a condom or where at he wanted to dump that 3 day load of his.. I had never been fucked like that before and to my surprise i called out while getting fucked that i wanted him to cum inside me and before I got to tell him not to pull out i felt an intense hot burning sensation deep inside my ass as he instantly pulled out after with his cum just shooting out of me, as if i had just taken a hot enema, and his cum got everywhere! there was a thick puddle on the floor and a river of cum flowing out of me and onto the sheets at the foot of the bed, he instantly starts to get dressed and part of me just really wanted to lay there for a minute and process everything but he had me quickly get dressed after handing me my buttplug, and led me to the door followed by a quick goodbye, getting into my car i glanced at the time on my phone and realized I only had 10 minutes until I had to be clocked in and at work.. I got there a few minutes late having to hurry into the back of the store to clock in the whole time im still feeling that mans cum slowly trickling its way down the inside of my ass and down my leg.. and I have finally got to experience what every bottom had told me is a must have feeling for all bottoms to experience.. I only wish he wouldnt have pulled out so quick so that I would have savored the feeling a bit longer. since then I've got to feel smaller warm loads pumped inside me but nothing was ever as close in feeling as that first guys 3 day load! easily one of the best moment I have ever experienced as a bottom!
