End if the world

I looked at the bomb in the distance in absolute horror, luckily Jack and I were far enough that we wouldn't get seriously hurt. Aside from the radiation burns, and the extreme hearing damage.
I wake up and my ears were ringing, and it sound like a river inside of my head. I had a crippling headache and I was covered in burns. Jack was still knocked out next to me. His eyes started to clutter open slowly and he got up.
"What...what the hell?!" He yells
"Everything....is...." I started to choke up and couldn't get my words out.
"Mark..." He walked over to me and hugged me tightly.
"Let's go..look for people..." I say in between sniffles. I whimper, and he takes my hand as we walk looking for survivors. All we saw were dead people, and the occasional rat or dog. I hug Jack from behind and cry into his neck.
"Mark...what are you...?"
I cut him off by kissing him deeply.
"Mmmph?!" He breaks off the kiss.
"Mark what the hell?!"
"I'm just so sad, and we're all alone, and I need someone."
"But we're both straight."
"Doesn't hurt to try...."
"Fine....but I'm going to top."
"Or...I could ride you..." I blushed and looked down.
He gulped and blushed. "Okay..."
I fluffed his hair, causing clouds of dust to come out. He takes my hand again, and we walk into an abandoned house. It looked clean, but we wanted to check everything. In the misted of checking all the rooms we found a room with a crib, and some baby toys. I tear up and hug Jack, and nuzzle his neck. He pats my back slowly and looks horrified at the sight. There wasn't anything violent or disturbing...it was just...sad.
After we got over that, we decided on a bedroom with a king size bed. Jack lays down and sighs. I jump on his lap. He jumps and gasps loudly.
"Oh yeah..."
I kiss him and he kisses back, I start to grind on his bulge. We both moan into the kiss, he explores my mouth with his tongue. I moan into the his, and I notice he begins to get hard.
"So...you're....enjoying this...?" I say in between moans as I grind him harder.
"Apparently...this feels so...good" Jack moans and I feel blood rushing through my body and I get butterflies. I take my pants off, and follow with my boxers. He only unbuttons his jeans, revealing his large hard erection. I blush, and set myself down on him, facing the opposite way.
"Ah!" I moan in pleasure and pain.
"Mark, don't you need any lube?"
"We...don't have any..."
"Okay, then this'll hurt for a little bit..."
I start bouncing slowly moaning, feeling both pain and pleasure. But soon the pain went away and my whole body was overwhelmed with pleasure. I moaned so loud, the dead could probably hear. Jack was grunting, and moaning under me. Eventually we were both moaning messes and were almost screaming in pleasure.
"Oh Jack!! Yes! FFFFuuuuUUUckkkk..."
"Oh Mark, don't stop...you're so tight...ah!"
"I'm gonna cum daddy!"
"Me too..."
We both cum, and cuddle on the bed. We're panting like we ran a half marathon.
"Let's...do that...again..." I say panting loudly.
"No need to tell me twice..."
