When I arrived home, I found Mark in the backyard finishing up the last camera installation. He was naked and had a thin layer of sweat on his body which glistened in the sunlight.
Allen was putting my lawnmower, and tools back into the pool shed. He was naked too, his teen body tanned and glistening with fine layer of sweat as well.
"Well, I guess you two are pretty comfortable with each other now," I said, both turned around and smiled.
"I'm almost done and then I'll come show you how everything works," Mark said.
Allen said, "And I've got a date, so I was trying to finish up so we could spend a little time before I have to go."
"I'm going to go in and get naked, see you both in a few minutes then," I replied.
I went in and stripped naked, leaving my clothes laying across the back of my couch. A few minutes later, Allen walked in, he said he had to leave by six for his date, it was four now. I told him to run upstairs and shower in my shower. He smiled and took off up the stairs.
Mark came in a few minutes later. He was fully erect and dropped to his knees in front of me taking my cock into his mouth.
"Whoa! Hang on, I want you to use the guest shower, get cleaned up and then come up to my room." I instructed.
He nodded, gave my cock a long suck and then headed to the shower.
I went upstairs just as Allen was coming out, his body was still damp, and a little pink from the hot shower. His cock was fully erect and he smiled as he looked at mine.
"Did you like fucking Mark?" I asked, stroking my own cock slowly.
He nodded, then said, "Yes, his I really did, but I think I still like getting fucked even more."
"Good, because when he comes up, you are going to fuck him, while I fuck you," I said, smiling.
His face lit up and he smiled back, "Wow! That will be so hot!"
Mark came in about that time, naked as well and a little damp too.
I motioned towards the bed and said, "Mark, bend over the bed." He did and I ran my hands across his plump bottom, parting the cheeks of his ass and pouring some lube down his crack. I then slid a finger into him.
"Allen, get a condom on and come here," I ordered. He did as I said, slipping a condom onto his erect cock.
When he walked over to us, I rubbed some lube up and down the length of his cock. I then positioned his cock at the entrance of Mark's anus and started to push it in, pulling Allen closer to Mark's butt.
Allen pushed forward until his full length was buried in Mark's asshole.
I then took some of the lube, smeared it on my own cock, then spread Allen's 19 year old ass cheeks apart and smeared lube on his crack and hole. I then stepped up and slowly slid my cock into his tight ass. Slowly, inch by inch I slipped into him.
He moaned deeply as I entered him, Mark was moaning too. Soon I was fully inside Allen, and breathing heavily, I said, "Allen, now just rock back and forth between us."
I eased about two inches out of Allen and felt his ass following me, then he slid forward, pushing back inside Mark. He finally got a nice rhythm going, pulling about three inches out of Mark, as the full length of my cock slid inside him. Then he would slid the full length of his cock back into Mark, leaving about three inches of my cock exposed.
He picked up the pace and was fucking Mark harder and harder, as he fucked himself on my cock at the same harder pace. I reached around him and played with his small pink nipples and kissed his neck.
I whispered, "How do you like this Allen? Do you like my cock in you and your cock in Mark?"
"He leaned back into me and moaned, "Yes, oh my yes, your dick feels amazing and his ass is so tight."
Mark then moaned and said, "Fuck me Allen, fuck my fat ass, fuck me, fuck me!!"
Allen fucked us harder and harder and soon I could feel my orgasm building. I felt Allen's ass tighten and knew he was getting close too. Mark let out another moan and said, "Guys I'm cumming!"
Allen followed next, "Oh fuck! Oh Fuck! I'm cumming too, oh fuck!"
