We, the 'residential care home' residents, had all been offered an experimental implant and out of some fifty people 'in residence' something like half of us had agreed to be willing volunteers to test the effects.
Approximately two thirds of us were males, generally between around sixty and eighty years of age. The implant was said to substantially enhance sexual enjoyment and activity in more elderly people -- and it proved to be excellent.
The one strange side-effect however was that the implant seemed to warp our sexual orientation so that normally heterosexual people tended to become homosexual or at least bisexual but because of the extra sexual enjoyment that we were all experiencing, no-one seemed to mind. Perhaps it was that our bodies had been adjusted as well...
Whatever, once the slow-release chemicals had begun to take effect, an ever-growing band of newly eager sex lovers could be found, most of them enjoying some energetic debauchery with others of their same gender.

The previous evening had begin like so many others with scatterings of residents gathering in the several lounges, with a group of four of us monopolising one room. We were all 'pals' from our seating arrangements at meal times, the four of us being Bill, Dick, Joe and myself, Chris.
We'd chattered together with no boundaries and then, after we'd retired to the privacy of our units the evening had descended into a debased orgy between Bill, Dick and myself with only Joe, who had family visitors round missing out and now, the morning afterwards, I awoke after an excellent if somewhat heavy night's sleep.
I sat up and stretched, instantly feeling spasms shooting inside my arse as I did so.
"Ahhh, what was that?" I muttered to myself, immediately realising what the answer was.
I gently let my finger explore the surrounds to my arsehole and the hole itself, feeling that while it seemed intact, it was quite tender in places.
"It was Bill's bloody great cock, wasn't it, oh and Dick of course," I admitted as the feelings settled down, "Mmmm, that was good fun actually!"
It had been the first time that my hole had been penetrated by anything more basic than a doctor's finger and most definitely the first time that anything had been squirted inside me but while it had come as a huge shock to me, I'd also enjoyed it enormously.
I rose and then peed and washed and also applied some soothing balm to the more tender parts of my anatomy.
"That's better," I murmured as I clenched my arse cheeks then gently flexed my hole, "Now, what's for breakfast?"
As I dressed I decided on cereals again and once settled over my breakfast I pondered on what to do today. I let my mind wander idly and then, as I rose to put my bowl in the sink so I caught myself on the edge of the table. It wasn't really painful but I was surprised because I wasn't usually clumsy but then I realised that the usual bulge in my shorts seemed perhaps somewhat larger than I was used to.
"Eh?" I asked myself, "What's the matter? You're not horny, surely?"
During the exertions of last night I'd emptied out any backlog of sexual need and normally it would be at least a day or two before I needed to gain any release but now I wondered what was going on.
I pulled my shorts down and stretched my underpants out and there he was, my penis in it's usual place, of course. The action of squashing it against the table had made it begin to fill out a bit and although it was still reasonably flaccid it looked bigger and heftier and inevitably I lifted it up and wrapped my hand around the shaft to see if it was ok. Within seconds I felt the blood rushing into my cock which began to grow and stiffen and then, with my hand sliding on my shaft I peeled back my foreskin. My knob appeared, glistening healthily as it filled out.
"You look good today," I said to my cock, "But what do you think you're doing sticking out the way you were?"
Obviously I expected no reply but instead I stepped over to the cupboard and fished out a tape measure from one of the drawers.
"You're well over seven and a half inches," I murmured a few moments later, "Hey, you've grown, haven't you!"
He had -- oh, not a whole lot but he was definitely somewhat larger than he used to be and seemed somewhat thicker too.
"Haha ha!" I chuckled as I held my penis, "Never thought that would happen at my age -- guess you're ok though."
Ignoring my cock's eagerness I shoved him back in his place and patted the bulge.
"Now you stay there until we know what's going on," I said as I redressed myself and did my washing up, "I think perhaps we should get you checked out -- see if this is anything to do with that implant."
Seeing that it was now just after nine o'clock I guessed that everyone would be up and active, so I phoned through to the office where I was informed that 'Doctor Shirley' from the Ejax laboratory was in the medical room and was available without appointment.
"Just the job," I said as I checked that I looked clean and tidy, "Let's see what she says."
A few minutes later I was being let into her office and before long I was seated beside her desk and had explained the gist of my problem, such as it was.
"That's not usually what men complain about!" she said with a laugh, "But I can understand your concern."
"Yes, well, it's something of a surprise," I said, "I wasn't expecting it to get any bigger -- I did all my growing long ago."
"I think the implant is indeed the most likely explanation," she said placidly, "It just seems that the treatment is working extremely well on you."
"That's good, but if you'd told me before I wouldn't have had to see you," I said, bemoaning the fact that I was wasting an hour of our time.
"We did actually tell you," said Doctor Shirley as she held up one of the pamphlets that they'd handed out, "This is one of the side effects that was mentioned in the handout in the first place, isn't it."
"Oh -- perhaps it was," I said as I tried to cast my mind back, not having read the notes thoroughly, "Still, is my err, thing healthy, that's what's more important to me."
"It's your penis, dear boy!" she said lightly, "Or your cock, whichever you prefer but don't be shy about it with me -- that's what we deal with all the time."
"I'll try not to be," I muttered, still somewhat reluctant to use the words to her, doctor or not.
"We'd better take a look then, hadn't we?" she said, "It certainly doesn't surprise me that it's grown although of course, we're still discovering how it can affect people and some more than others."
"Nothing untoward I hope?" I asked of Shirley, "You haven't found any nasty side-effects?"
"None that we know of," she said as she patted my thigh gently, "But I'm glad you came in; perhaps we can take some measurements and keep an eye on how things go."
"Yes, good idea," I agreed, "Nice to know what's going on."
"Of course, we'll need to measure you erect," she said, "Perhaps you'd be so good as to stand up and we'll get going."
I felt a hot flush of embarrassment enfold me as I realised the implication but a moment later Doctor Shirley laughed and held my hand, her own hand soft and gentle.
"Don't worry," she said soothingly, "I've seen it all before -- and I do believe that you were naked for Doctor Judy, weren't you?"
I nodded as I undid my trousers and let them fall to the floor, pushing my shoes and socks off as I did so.
"And I also understand that you showed some excellent responses to her," she said, her voice soft and soothing as she helped me step out of my trousers, "She was quite impressed apparently!"
Her smile was wide and friendly and her eyes seemed to sparkle with enthusiastic interest.
"It was her fault!" I spluttered as I pushed my underpants down and stepped out of them too, "I'd have been alright until she stroked -- ahhh, oooohh!"
Shirley had taken my cock in her hand and with a few smooth and steady strokes she had him rising into a good solid erection, then she let go and stood back.
I thought she was going to fetch some instrument then but instead she merely crossed the room and locked the door before returning.
"That'll make you feel more comfortable," she said softly as her hand surrounded my shaft again, "And what a nice looking penis you have!"
I simply couldn't think of a good answer but instead I just stood there as she stroked me until she stopped and released me, my cock quivering with excitement.
"I think we ought to ensure that you're absolutely fully erect," she said, "It feels pretty firm to me but perhaps we can make it even stiffer and bigger -- let's see if this helps."
She stepped away and then began to undress before me while I stood there with my mouth open in amazement.
Quickly her skirt was removed and soon afterwards her blouse was discarded too, leaving her standing there in a very skimpy bra and panties set. Her firm bulging breasts filled her bra to capacity and her dark brown nipples were very visible, flattened against the material, while down below it was very evident that she'd shaved most of her pubes away.
"There, how does that make you feel?" she said softly as she slowly turned around, filling me eyes with her delicious body.
"Amazed -- you're beautiful!" I breathed, unable to formulate anything better, "Simply fantastic!"
