"Are you sure you want this?" Gray asked shocked by what Zach had just said to him.
His big brother, who he has known for his entire life just gave him clearance to fuck and he did not know where to begin.
"Yeah, I'm sure Gray. I deserve it honestly... I fucked your virgin ass without consent... which is actually technically rape but that is for another lesson..." Zach said.
"Okay... so where do I begin?" Gray asked.
"Well... First you have to get hard obviously, Remember what I taught you earlier?"
"I need to masturbate?" Gray asked
"Yes, but not all the way. Only masturbate until your dick is as hard as it can be, then we can move on to the next step" Zach said "Here, I will even help you with it"
Zach walked over to Gray and put his Hands on Gray's dick. It just felt natural now to touch it. Gray's Penis started to perk up immediately and soon it was at full erectness.
"Okay, now we need some sort of Lubricant. We can go rough like I did with pure water or we can go as far as using soap."
"Can we use spit?" Gray asked out of nowhere
"Well... we can... But Spit is not the best for Lubrication."
"Let's just use spit then!" Gray said with a smirk. "Now get sucking".
Zach was surprised at how Gray worked this and was impressed.
"Gladly" Zach said with a gulp, he had already did literally an hour or two ago but he was still scared of the idea of sucking a dick, but he didn't want to look like a wimp so he did it again.
Zach moved his head to over Gray's penis and started sucking for about 3 minutes, after this time he thought that there was enough spit on there.
"Okay, now Gray, Here is the interesting part. I am going to lay flat on my stomach on the bed. All you have to do is aim for my Asshole and go for it, you don't even have to warn me because of what I did earlier." Zach said as confidently as he could. Zach was terrified of the Idea of an object entering his asshole, especially a piece of another human.
Zach went over to the bed and did what he said he was going to do. He laid flat on his stomach and waited. He felt the bed shake as Gray started to move over him. Both were in position and it was now go time. "Now Gray, I didn't tell you about another way of getting ready for anal FUCKINNGGGGGGGGGG" Zach said as Gray plunged in. Zach fainted immediately, just the trauma alone caused it.
Gray didn't even notice that the body below him had gone unconscious and just kept going on. The sensation of Zach's tight ass on Gray's penis were making Gray's mind go haywire. Gray started to push in and out as he did when he was getting the blowjob, back and forth, back and forth, back and forth. It was a common pattern for about 6 minutes. Eventually it became too much and and while Gray could not cum because of his age, he still had his pee building up. It got to so much that Gray ended up peeing in Zach's ass.
