[Previously: Timmi and Clay, two twin brothers at college in Miami, have undertaken to be guinea pigs in some research conducted on muscle stimulation. But there are side-effects to this study, and one of the more powerful ones has been to increase the twins' libido, and make them more aware of each other's sexuality]
Five weeks ago
Finally, I had caught Timmi fucking himself!
It had become almost a game, especially over the last week or so, since our most recent injection from Dr Daniels. Timmi knew that his vibrator had been moved from place to place, and had probably guessed that it wasn't mom doing the removals. And as for me, I knew that if Timmi was feeling anything like I was, he was feeling horny all the time these days. If he was feeling as horny as me, he was jerking off in the morning, screwing his ass during breaks at college, jerking off at lunchtime, screwing his ass in the afternoon and taking a long, leisurely ass-fuck/jerk-off in the evening.
We both suspected what the other was up to, but neither had caught the brother in the act of doing it. Until earlier this morning, when I'd gone to the bathroom, but come back to the bedroom we shared having forgotten to take my clean boxer shorts with me.
I had left Timmi on his bed, sitting up with his pink panties on, rummaging in his cosmetics box to put on his make up. He put on make up every day now. Sometimes subtle (like, during the day at college), sometimes more flamboyant (in the evenings, when he would dress up in other girls' clothes). He and I had shared a few laughs with his make-up, and I had worn it now and again, but not with the same fluency or urgency Timmi did. And, Holy Macaroni, did he look pretty when he wore it.
So, anyway, I had gone back to the bedroom and walked in without knocking (like I always did). There was that moment of disconnect as I saw Timmi fumbling with his dick in his hand. He was sitting right on the edge of the bed; his long, slim legs spread wide and his erect cock standing up for me to see.
"I, uh- Ah, sorry Timmi. I just needed to get my boxers." I said, feeling a little red around the cheeks as I caught my brother in the act of jerking off. Timmi smiled shyly at me, biting his lower lip as he knew he'd been rumbled. He didn't say anything. But, by the same respect, he didn't take his hand off his hard cock either. He just sat there, legs spread, on the edge of his bed. I took my boxers and went to the bathroom, feeling somehow embarrassed.
I thought about that little incident all day at college. Like it wasn't enough that I was checking out all the guy's asses at school, even without thinking it. I still looked at girls, sure, but somehow, that little erotic itch in my ass had me turning my head to look at other guy's asses. Ashamedly, I caught myself staring sometimes for long moments at my brother's ass; looking at the gentle curve of his ass cheeks as he walked; marvelling at the tightness of his cheeks and slimness of his hips, wondering if mine looked as good as his.
So, it was kind of a relief in the evening when mom made us an ordinary dinner and Timmi and I argued about football. Clearly, I said, the Dolphins were going to make the playoffs. Timmi had thought not, then got onto his hobby-horse about how 'stoopid' football was. We didn't argue a lot, even before we took Dr Daniel's injections, but it really felt like a petty lover's tiff more than a guy-guy argument.
Anyway, it was bizarrely refreshing to think about my brother being an asshole, rather than thinking about his asshole.
Mom went off to one of her Liberation Circle meetings, leaving Timmi and I to do our chores. We did so, scowling or pouting at each other. At one point, Timmi actually poked out his tongue through Dusk's Kiss lips! He hadn't poked his tongue at me since we were, like, four.
He took off, saying he needed a shower. I pretty much knew what he was going to do, but was still a little annoyed and waved him off. Fine. Go then. Have your (jerk-off) shower.
I sat down to watch some tv and, within a short while, heard the hiss of the boiler kick in as the jet stream from the shower demanded more hot water. That went on for a few minutes, then stopped. There was a pause, then an almighty crash. I heard Timmi cry out, and was up, running up the stairs before I could even think straight.
I crashed through the bathroom door to see Timmi lying naked on the floor, holding his side. I rushed in to him and collapsed on the floor beside him, pulling my brother into my arms and holding him.
"Tim! Timmi, are you okay?" I said, hearing the crack in my voice as I wrapped my arms around him. I felt Timmi stiffen a little, then settle in to me. My God. I had just been arguing with my brother and there he was; hurt. If it had been worse, if he had been really injured, he would have thought that I didn't care for him. He would have thought that I was still angry and didn't love him as much as I did. He would have-
I pushed the thought away and held on to Timmi, gripping him tightly in my embrace.
"I'm okay, I'm okay" he said, his voice small but even. He disentangle himself from my embrace, then winced as he turned to sit up, his back against the side of the bath. I rocked back on my heels, feeling tears sting my cheeks. I wiped them roughly with the cuff of my now-wet running top. Timmi looked at me and smiled.
"Hey" he said, reaching out to touch my face with his hand. "It's okay. It's okay. I just slipped and fell, is all. Just a bump on my ass. I'm okay."
"Jesus, Timmi!" I said, holding onto his hand as he held it against my face. "I thought something really bad had happened. I thought you had-"
I couldn't finish the sentence I was going to say as the words chocked in my throat. Timmi leaned forward and pulled me into an embrace. I felt his long, soft fingers at the back of my neck, lightly stroking and massaging my skin. His breath, and his voice was at my ear, shh-ing me, and telling me he was okay, that I shouldn't be so upset. He kissed my neck, just below my ear, and hugged me again. We sat like that for a moment, until I let the emotion pass. Timmi pulled away from me a little, and smiled at me.
"I'm fine, really." He said. "But thank you for coming to rescue me. My hero." He added, leaning forward.
He kissed me, lightly, on the lips; still smiling. His soft lips pressed against mine and I felt an immediate thud in my chest as we kissed. He held back, then kissed me again, this tie angling his head a little so he could kiss me more effectively. He broke off again, tilted his head the other way and kissed me a third time; slowly, ever so slowly, his lips smacking against mine as he eventually pulled away. It was incredibly sensuous and erotic. My ass was itching like crazy, and I knew that my cock was bulging in my shorts.
I looked down, momentarily, and that seemed to break the spell. Timmi looked down too, then up, a shy, half-grin on his pretty lips.
"Go on; get out of here." he said. "I'm fine."
I frowned, unsure if I could trust him after the accident, but he jerked his head toward the door.
"Go on. I'm fine. Break out a couple of beers, Clay. I wont be long."
I got up, reluctantly, and headed for the door. There was no mistaking the look in Timmi's eye as he glared at the bulge in my shorts. It was a hungry look.
"Let me see you can get up alright." I said, pausing by the door. Timmi rolled his eyes, but reached for the side of the bath to haul himself up. He stood, naked and lithe; still wet from the shower, holding a hand against his right hip. His gorgeous cock; seven inches of undeniable lust, stood out 90 degrees from his crotch.
"There. See? Nothing wrong with me." He twirled, showing his back to me, and I let my eyes travel down his back to the tight ass cheeks I'd checked out earlier that day. I made sure he knew I was staring intently at him.
