We, the 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 and if my own experiences were anything to go by, we were all enjoying the effects thoroughly.
The implant was said to substantially enhance sexual enjoyment and activity in more elderly people - and it proved to work excellently well.
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.
It seemed that the chemicals in the implant were adjusting more than just our bodies...
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.

Bill, Bob and I walked together down the wide corridor, our steps confident and urgent. We'd had our evening meal and now, with the rest of the day being ours to enjoy there, was an air of expectant excitement about us somehow and Bob turned to me, his eyes aglitter.
"Are you looking forward to this?" he asked quietly, "I am - I've never had so much fun!"
"Nor me although thanks in part to your dad I've had some pretty wild times here already," I admitted, "I wasn't actually into this kind of stuff before this implant so this is all new to me, but it's good though."
"Yeah, Dad was the same as you," agreed Bob, his head nodding, "But I was always much more open to anything - you know - the modern generation and more willing to explore I guess. Not only that I think I've been bisexual all my life."
He paused as we reached Bill's door, then, as Bill opened the door he spoke again.
"I'd been living away from home for some while, but once Dad came to live here we started to meet quite regularly," said Bob, "And then suddenly we seemed to click and we actually became quite close."
"What, you mean you started to have sex with one another, in other words?" I asked and Bob smiled and nodded willingly.
"Yeah, well Dad wasn't entirely sure which way to turn, so we started to experiment," he explained.
"That was because when I came here I met Joe," said Bill, having overheard our conversation, "As you know, he's gay and I wasn't so I just didn't really know what to do or how to do it."
"But you do now, don't you!" I said with a laugh.
"He sure does!" added Bob, "And what's more, after he'd had his implant he was all over me. It was great!"
"I bet it was!" I said, imagining the two big cocks together, "And now you're looking forward to enjoying me as well!"
"Damn right I am!" said Bob happily, "Can't wait!"
A minute or two later and we were inside Bill's unit being plied with cans of beer and then we were settling in his lounge, Bob and I side by side on the sofa and Bill in his armchair. We made small talk for a bit, unwinding and relaxing and emptying our drinks and then Bill stood up, soon leading the way to his bedroom, stripping off his shirt as he went. By the time Bob and I had our t-shirts off Bill was naked and was displaying his already generously enlarged penis and it wasn't long after that that there were three stiff cocks on show.
I felt aroused and wicked and it was I who made the first move, kneeling down before Bob's tasty looking cock, grasping it and pulling it eagerly into my mouth.
In seconds he's stiffened up completely and as I let his knob fill my mouth I felt a pulse of precum ooze from him.
"Mmmmm, tasty!" I moaned as I sucked hard, hoping for more and Bob moaned too.
"Ahhh, yesss!" he groaned, his hips thrusting forward, "That's perfect - you're good, aren't you?"
"Yeah apparently, Joe says I am," I agreed as I pulled away from his penis briefly, "Do you want me to carry on?"
"Yeah of course, suck him off Chris," added Bill as he stroked his own stiff penis, "I don't think he's cum today so I bet he's fully loaded - suck one out of him and he'll be nicely primed for later."
"No I haven't cum today," said Bob, his cock surging urgently into my mouth, "This one won't take long - hope you're ready."
I nodded slightly as I settled to my delicious task, letting Bob's thick cock slide deeply into my mouth - almost into my throat - then working on his knob alone, while Bill stood beside us watching and gently massaging his erection. Every so often I'd be rewarded with another slippery taste of precum, often preceded by Bob thrusting his cock at me as spasms of lust drove him on. I kept sucking, now adding my fist around his lengthy shaft to encourage him to cum and whatever I was doing was clearly working.
Every few minutes he'd grunt or gasp and his body would shudder and shake as he grew closer and closer to his climax.
"Come on Chris, make him cum!" said Bill eagerly, his hand now flying up and down his own penis as he watched, "Suck him hard!"
"Ohhh fuck, I'm almost there!" Bob finally cried, his words accompanied by another strong thrust and then his hand settled suddenly on my head.
"That's it!" he exclaimed quickly, "Ahhh, like that - ohhh yesss, ohhh fuck!"
"Give it to him!" urged Bill as he stropped his huge penis beside us, "Fill him up Bob!"
"Going to; won't be able to stop soon!" grunted Bob as his cock stiffened anew in my mouth, "Ahhhh - here it cums - here it cums!"
His fingers tightened on my head as his cock thrust strongly at me and then I felt the swelling pulsation inside his penis as his cum rose up his length, blasted from his tip and began to fill my mouth.
"Ohhh yesss!" he cried as his penis squirted his first load of hot urgent cum into me, "Ohhh, fuckin' take it - take it all!"
I did my best, swallowing his first load quickly and then he was pumping more cum into my mouth so strongly and generously that it squirted from around his penis and my lips. I felt the warm juices sliding down my chin but there was plenty more to enjoy and I quickly swallowed again.
His spunk was warm, tasty, sticky and slippery all in one as it slid down into my belly and then finally I was left with a mouthful of quivering, slippery, velvet-soft cock and the last vestiges of his spunk.
My tongue quickly explored all the little corners of my mouth to extract the best from his tasty essence but sadly I found very little remaining to enjoy.
"That was really, really good!" I said happily as I lifted my head from his cock, "Terrific load Bob, thanks; loved it."
"You were so good," said Bob simply, "What an amazing mouth you have Chris."
I shook my head because to me I was no expert at blow jobs, but Bill now joined in.
