Rehab for butt-boy part 2

The first time we messed around was after a days work washing cars at one of the ministries car washes. At around 6pm we would all pile into a van, the long kind you see carrying field-workers and go to the kitchen to eat. After that, we had 30mns to wash the dishes and sweep up. Next came Group. Group was led by the pastor himself and what started out as 12 step meeting, could end up as a write-up session with someone losing privileges or being busted down in rank over something that had been reported earlier in the day. It was after group, that we went home to an apartment complex that the city had donated to the program. Each room of each apartment had four beds apiece and some of the guys liked to drink coffee and cruise around to other apartments in the complex to gossip before lights out.
Greg and I were in our room taking off our shoe's and waiting for a turn in the apartment's shower. It was here that I learned why, more or less, Greg came to be in the program. Towards the end of the conversation I began to rub my neck and shoulder to relieve the days soreness. Greg pounced on the opportunity and told me that he gave great massages.
Now at 22, I wasn't stupid. I knew from Greg's mannerisms and the lilt of his voice that he was gay. Not to mention the story he had just told me about the 17 year old boy. Truth is, I was kind of horny and wanted to see where this was going so I led him on. "I usually have a masseuse table, oils and incense to work with, but I think I can manage" he said. I gave him a sheepish smile and by way of permission, turned slightly on the bed, sitting at an angle with my back to him as I looked over my shoulder.
Greg didn't waste any time as I felt his strong hands kneading my shoulders and his hot breath on my neck. It felt good, really good as he worked his way down my back along my spine and up again. I began to feel a tingling in my penis and my balls were starting to get hot so I opened my legs slightly to get some relief.
Greg didn't miss a thing and as the tingle turned into a chubby in my boxer's, he remarked, "Well, what have we got here!" I soon felt his hand touching the fabric of my shorts, rubbing my hardening cock and giving it a maddening squeeze here and there. "My!" "It's so big!", he says. "What do you do with that thing?" "Hammer nails?" I said nothing, just closed my eyes and let him. Soon we heard the bathroom door start to open and had to scramble to look nonchalant as Gordon entered the room in boxer's and flip-flops. I was on my belly pretending to read the 12 step guide and desperately thinking about baseball to get my raging boner down. Greg was making his bed. Aftera shower, some chit-chat about the next day and the arrival of the fourth guy, we turned in for the night. Lights out!
I remember lying there in the dark thinking about the evenings earlier encounter and listening to the rythm of the men's breath, waiting for the deep slow pattern that would tell me they were asleep. I was slowly fondling my balls making them swell, thinking about Greg's dick going into my tight ass. Sometime after midnight I slowly slid off my bed. Very slowly, I wanted the other two to remain asleep. As I made my way on my hands and knees to Greg's bunk, I stopped and listened for any interruption in the others light snores.
When I got to Greg's bed, I found him awake. Guess he was up and horny like me. "What!?", he whispers. "I want you to fuck me.", I whisper back. "You're crazy, they'll hear!" "Come on!", I said as I stroked his cock through his pajamas. It was hard and straight, felt about 5". Good I thought, I can easily take this up the ass without to much trouble.
I left off stroking him with a playful squeeze and quietly crawled my way to the open closet with my ass up. I put my head down in the dark of the closet with my ass pointed up as I slid off my boxer's and opened my heels to accept Greg in. I heard him breathing as he came near and positioned himself between my feet. Fumbling now with his pantsin the dark..
Ahhh! I felt his hands on my ass high up, and his hard dick probing and rubbing along my taint and crack, trying to find my donut. I had come as prepared as I could have under the circumstances. They gave us these little bottles of airport shampoo and conditioner along with soap and toothpaste. I had tucked the conditioner in the wasteban of my boxer'searlier and now used it as I reached behind and stroked it on Greg's pecker. I also put some in my butt-crack and slowly teased my tight throbbing ass hole with my finger. As I opened up my cheeks with both hands I moved my ass up and down, rubbing his dick in my crack and slowly positioning it right outside where I needed him to push.
I felt the head against my tight hole, pushing. I slowly let out my breath in the dark and closed my eyes. It was very intense and I felt him shaking slightly. I pushed my ass against his hard dick and felt the tip opening me up. Oh, the pressure felt so delicious! I put my hand against his thigh to slow him down as my hole got used to him. Slowly, I backed myself all the way onto his throbbing meat and felt him(heard?) Gasp, as he established a rythm going in and out, pumping. I felt one of his hands holding my left cheek open and the other moving down my back for leverage. The pumping became more intense. Wild thoughts of getting caught went through my mind as the thrill of it all made me shiver from the tips of my fingers to my throbbing ass. What if those two woke up right now and saw Greg plowing my ass! I was almost cumming from the fear and shame!
This whole escapade reminded me of when I spent the night at my aunt and uncles house. An older cousin crept into our room in the early hours of the morning and pulled down my jockeys. Even at that age, I knew what was going on. His fumbling with his fat member against my small backside felt so mysterious at the time. I was curious and wanted to see what it felt like, so I pretended to be asleep.
I decided that I needed Greg's seed right then and there so I arched my back and gave him all my ass. I began matching his rhythmic pumping, pushing back to meet him as his dick and my ass slammed together in ecstasy.
I felt him shudder with a low grunt as I ground my butt on his shaft all the way to the hilt. That's when I felt him gripping my cheeks as he pumped his hot seed into my hole. It felt so good, I came all over the closet floor, not caring about the mess. It was all it could do to stifle my gasp of pleasure. Greg was fucking me in long slow srokes now and breathing heavily. With one last thrust, he pulled out and I could feel the cool air on my slick pulsing hole as his nut dripped out and ran down my balls.
