Trent was excited for the camping trip. He had recently become engaged to his girlfriend of four years, Sara. This meant they wanted their families to become closer too. And part of this commitment was Trent becoming closer to Sara's younger brother, Mark. Trent thought Mark was cool enough but seeing as how Trent was 31 and Mark was 18, the two did not seem to have much in common. The one thing Trent loved that Mark seemed to enjoy though, was camping. When Sara was unable to get the time off from work for the trip, Trent asked Sara if she thought Mark would be interested. A quick text message between Sara and Mark confirmed he was interested and would be happy to go. And so, it was set for the following weekend.
The following weekend on Saturday morning, Mark parked his Honda Civic on the street, outside of Trent's house and stepped out of the car. Mark had just turned 18 a few weeks ago, right around the same time he graduated high school. Looking at Mark and Sara together you could tell they were siblings. Mark was average size, about 5'8 tall and 155 pounds with black hair and blue eyes, just like his sister. He was always clean-shaven, and Trent joked to Sara that Mark could not grow facial hair if his life depended on it. Mark had an athletic build due to his constant playing of tennis and swimming.
Trent opened the front door and walked outside to greet Mark. The two were opposites and you could see it clear as day when they stood next to each other. Compared to Mark's average build and boyish good looks, Trent had a large frame and had that rugged look that drove Sara wild. Trent was 6'2 with a solid build and had a trimmed goatee. Trent had camped and worked on farms his whole life and looked the part. He was ruggedly handsome.
This was to be a male-bonding and family-building adventure. Sara recently told Trent that Mark had "come out" to her as gay. This surprised Trent as Mark never displayed any stereotypical signs of what Trent believed would indicate someone was gay. Mark was Sara's brother though and it did not bother Trent either way who Mark found himself interested in.
Mark quickly hopped into Trent's truck which Trent had prepped the night before with everything they would need and the two drove away towards the mountains. Two hours was all it took to get deep in the heart of the wilderness up there and Trent had the perfect spot picked out to set up camp. It was a beautiful spot: a nice flat clearing to set up two tents, large trees all around for shade and protection from the wind and rain if there happened to be any, and a gentle flowing river just minutes away. The two exited Trent's truck and got to work. Trent had to show Mark how to set up the tents and after that task was done the two did some fishing.
The two discussed life matters, what Mark wanted to do after high school, what schools he was planning on applying to and other matters. "So, Sara mentioned you are into dudes?" Trent asked Mark in his typical nonchalant and confident demeanor. "Yea, I don't know man, it is something that I have known for a while but have just been too scared to bring up to my family" stated Mark. And with these two short statements, the two talked about it in detail for the next hour. This is what Mark loved about Trent, he was a man's man and looked like he could deal with any trouble that came his way, but he was also caring and always treated Mark fairly and with respect.
As the night wound down the two built a large roaring campfire which they sat near and chatted around well into the night. During this conversation, as the two were very relaxed and warm around the fire and enjoying the view of the stars, was when Trent began letting his mind wander. He had not gotten sex from Sara for almost a week because it was "her time of the month" and Trent was sexually frustrated. He was a man to the fullest and needed sex at least a couple times a week. Trent had never been with a guy before except for that one time in high school where he and his buddy were watching porn and jerking off. His buddy leaned over and for the next few minutes used his hand to stroke Trent's cock up and down. Trent remembered this clearly and it always turned him on thinking about how his friend was in awe at the size and thickness of Trent's cock. These thoughts flooded Trent's mind right now in front of the campfire chatting with Mark, and at that moment Trent's cock grew thick under his pants.
At the same time, Mark too was having his own thoughts. The first time he realized he was interested in guys was when his friend from high school showed him a cell phone video the friend took of him having sex with a school cheerleader. Mark remembered watching the video and being turned on by the whole thing, but one thing in particular, got his blood flowing. In the video, Mark could hear his buddy telling the girl he was about to cum and the low muffled grunts of his friend getting closer and closer before hearing his friend let out a large groan as he covered the cheerleader's stomach with his semen made Mark more erect than he had ever been in his life. After his friend left that day, Mark immediately went to his bedroom and thought of nothing other than his friend's dick and the sounds of him having an orgasm, and this made Mark get off.
Mark thought he could see a large bulge in Trent's pants, but he also thought it could just be the fire and shadows playing tricks on his mind. The two discussed Trent and Sara's upcoming wedding and that led to the discussion of sex on wedding day. Trent then made a comment that changed everything: "Fuck man, I'm horny right now" as Trent sort of smirked, "Your sister has been on her period and we haven't had sex in a while." Mark picked up on this and asked Trent more questions which led to a more detailed discussion. Trent looked over at Mark and thought he looked good right now. Nice athletic build, good looking younger guy. And the thing that appealed to Trent the most was the fact that Mark was Sara's younger brother. Trent knew that Mark had just as much incentive to not tell anyone about this as Trent had. He figured it was a safe bet.
