Hiking across Canada (part 2)

After that night of getting fucked for the first time by my college buddy (Bernie) while i sucked on a stranger's cock, it was awkward for a few days while we continued hiking west, towards the Rockies. We didn't talk much about it, other than to say we had just been "experimenting". A few days later, we had ended up in a campground. After a good shower, we found some booze and had a few drinks in the tent we were sharing. Bernie (5'10", 180 lbs) had rarely been without a girl every week during college, and after a few drinks in the tent, he tentatively asked if I could suck his cock, since he was VERY horny, and no one would know. He said it was ok if I didn't want to. I remember having his cock in my mouth a few days ago, and it was kinda nice. I agreed, and pretended it was "reluctantly". He laid back on his sleeping bag, and let me do the work. He wasn't lying when he said he was horny, cause It didn't take long to get his 7.5" cock rock hard. I was slurping on his cock, and he reminded me that there were other campers just beside us. After a bit, he pulled me on top of him, so we could 69. However, since I'm just 5'6" and 145 lbs, my small cock was resting on his chest, while I continued to suck his cock. Bernie only had a view of my butt cheeks and anus that he had fucked only a couple of days ago. Even if we had told ourselves it was a "one-time thing", he leaned up and started to lick and rim my anus. It felt incredible!! This went on for a bit, until Bernie moved me off of him, and maneuvered me on all fours on my own sleeping bag. out of nowhere, he got some lube out, and smeared my ass. I knew he was gonna fuck me again with his big cock, and I didn't stop him. he moved behind me and I could feel his hard dick push at my anus. I could feel something was different this time, cause it was not as "slippery" as the first time. Then I realized, he was gonna fuck me "bareback"!! I tried to protest that I wasn't sure about this, and he just "shushed" me, and continued to push himself inside me, stretching my ass again. There was some resistance, so he pulled out, and put more lube on his dick, and pushed himself inside me again... this time, it slide right in! On all fours, my buddy was behind me, slowly pushing his massive bare cock in and out of my ass. He did this a few times, then it got more intense. He pushed me down so he was on top of me, with my naked cock rubbing on the nylon cover of my sleeping bag. His strong arms went under my chest, and reached up to grab my shoulders, so there was nowhere for me to go as he pushed his cock balls deep into my ass in this new position. His cock felt massive, and rock hard. I told him I wasn't sure if I could continue like this... . He said to keep quiet, or other campers will hear us. I started to moan a little as he kept going in and out of my ass a little more forcefully each time. He realized that he may be too big for me for such a hard fucking, and he whispered into my ear "do you want me to stop"? I hesitated a bit as he slowly continued to penetrate my ass over and over, it was super intense, but there was no pain.... I didn't answer, so he asked me again "do you want me to stop?"... and to my astonishment, I exclaimed rather loudly that other camper probably heard "No, Please!... DON'T STOP!" At that moment, we both knew that I had just submitted my ass for him to use for his own pleasure, and i had become his little anal bitch! One of Bernie's arms held my shoulder tightly, as his other had covered my mouth, He started to really fuck me, probably like he fucked his many girlfriends. You could hear the slapping of bodies in the quiet campground. He was pounding my ass like a pussy, plowing the full length of his solid cock in and out of my now willing anus, pushing my cock against the fabric of my sleeping bag. His stamina was amazing, and he continued his savage assault as my ass was stretching and accommodating his solid thrusts. I whimpered desperately with each of his rapid deep thrusts until he exploded inside my ass with a loud grunt, while my cock spewed cum as well, causing my ass to pulsate uncontrollably around his spewing cock. After catching his breath, he smiled as his cock slowly slide out of my trembling ass, and with confidence of having successfully imposed his dominance over me and my ass, he exclaimed "I'm really going to enjoy fucking that ass all summer!". He wasn't even asking if I wanted to ever do it again... cause we both knew my ass was made to take his cock. That was the night that I discovered the incredible sensation of taking cock like a girl, and realized i had become an anal sissy, willing to please anyone with a big cock that wanted to fuck my ass. The next morning, everyone in the surrounding campsites were looking towards our site, expecting to see the girl who was whimpering while getting fucked... when they just saw two guys, it was obvious they could tell which one of us had gotten fucked like a little slut, and it kinda felt sexy having strangers know I had willingly taken a hard cock in my ass. I still have the cum-stained sleeping bag!
