At first, I felt violated by his explorations, but as his hands moved over my boobs I started to feel a strange hunger for more. He rubbed and squeezed me with increasing confidence whilst my brother watched from beside us.
I closed my eyes and felt my nipples harden against Chris’ fingers as I started to become aroused. Tristan took my hand and guided it into his lap. I fondled his weighty cock through his pants as Chris continued to explore my breasts. The sensation of Chris’s fingers on my nipples, Tristan’s dominance, and my own hunger for cock sent small waves of pleasure through my body. I felt ashamed and dirty, and yet I also felt fucking good.
Tristan’s cock swelled in my hand and I reached out with my free hand for Chris’ manhood too. Chris flinched in surprise when I touched him, his hands momentarily pausing on my breasts. As I started to squeeze his flaccid dick he relaxed and his groping resumed. His cock started to grow, it was a lot smaller than Tristan’s but nothing to be ashamed of. Tristan just happened to have been blessed with the cock of a donkey.
“Show Chris how slutty you are with your mouth,” Tristan said as he pushed my head toward Chris’ lap.
My face flushed with embarrassment but I didn’t resist. Once this night was done I’d be free 2 months sooner than planned. Chris raised his butt off the couch as I yanked his pants down and his cock sprung free. His size was about average but next to my brother’s it looked tiny. I wrapped my lips around it and easily took the whole thing into my mouth.
Chris groaned with pleasure and I felt a thrill knowing the effect I had on him. Chris’ fingers still played with my breasts as I worked my mouth over his hardening dick.
“Fuck this is amazing,” Chris said, taking hold of my head and forcing me down on his cock again and again. “You really are a fucking slut.”
“Yeah, Erin’s a real hungry cock whore,” Tristan said gleefully. I felt my brother’s hands on my bum, pulling my panties down. “Ever since she got a glimpse of mine she’s been doing whatever I tell her just for a taste. Isn’t that right, sis?”
“Mmhmm,” I said, my mouth still full of cock. Even though that wasn’t what had happened at all, there was some truth to it. Tristan’s cock was fucking perfect and my mind was plagued by images of it every day. I was ashamed of my desperation and yet I was thrilled by how horny it made me.
I could feel myself getting wet as Tristan fingered my aching pussy. I started to moan with pleasure, lost in my own world.
“I had no idea what a slut your sister was,” Chris said, as he gripped the back of my head and started to thrust into my mouth.
Tristan continued to finger me with his thick fingers. My wetness and his skill combined to create an intensity that I had never experienced before. And then it was gone as my brother pulled me off the sofa, Chris’ cock sliding out of my mouth, and dropped me to my knees on the floor.
“Tell us how badly you want this,” Tristan said as he pulled his pants down and revealed his magnificent cock.
“Jesus bro!” Chris said, impressed by Tristan’s size and no doubt feeling at least a little self-conscious.
I felt a wave of desire and humiliation wash over me. I had been reduced to begging for my brother’s cock, but I couldn’t deny how badly I wanted it. I was practically salivating just looking at it.
“I want it,” I said breathlessly. “I want your cock.”
Tristan leaned in and said, “We both know you want this but that wasn’t quite good enough.”
“Please let me have your cock,” I said, placing a hand on his thigh in anticipation.
“Why?”
I glanced at Chris who was watching me avidly, and then right back to my brother. “Because I need it. It’s so big and juicy and perfect and I need to taste it. I’m nothing but a slut for your big cock. Please let me have it.” I wasn’t even pretending.
I felt a surge of pleasure when Tristan smiled and stroked my head. “Good girl,” he said. “Now come over here and make me cum.”
I eagerly complied, my lust and desperation driving me forward. Tristan’s massive cock filled my mouth and I savored its taste. Chris watched us as I sucked and licked my brother’s glorious dick. I felt so dirty and submissive and I didn’t care who saw it.
Chris slid off the sofa and positioned himself behind me. I knew what he was going to do before I felt his cock at my entrance. A thrill of lust surged through me and I shuddered like the whore I was. Tristan’s thick cock filled my mouth while Chris’s slipped into my soaking pussy. His girth was unimpressive but his length hit the spot as he started to thrust.
They both moved in unison, pushing me to greater heights of pleasure I had never imagined possible. I longed for them to never stop and I didn’t care that I was debasing myself for them. This was so much better than anything I had ever felt before.
Chris started to pick speed as his lust for me grew. He didn’t have my brother’s finesse and he went at me like a rabbit, thrusting eagerly with little skill. I was so horny I didn’t care.
When I started to approach my peak, Tristan grasped my head with both hands and forced me to take him in deeper.
Tristan moaned his pleasure as his orgasm built up in his body. As Chris pounded away, going faster and faster, I felt my own orgasm building. My pussy tightened around him and then I felt an explosion like a tidal wave as all three of us came together. Chris shot his cum into me first. Then Tristan’s cock stiffened and he released his hot cum right into my mouth. Torrents of it shot down my throat. I swallowed it down eagerly, loving every second of it. As soon as I tasted Tristan’s cum my floodgates opened and my orgasm sprung free. As the intensity peaked, all three of us shared a shuddering moan of pleasure.
When it was done, I lay there in a blissful haze, the taste of cum still on my tongue. I had never felt so completely alive and desired. I felt like I was soaring. Those seconds evaporated quickly and I felt embarrassment wash over me. I lowered my eyes in shame, unable to look at either of them as they stared down at me. I’d been reduced to a horny, slutty mess.
Then Tristan smiled at me, not a gloating smile, but one of affection. “Don’t worry, sis, none of this will ever leave this room. I promise.”
“Yeah, I promise too,” Chris echoed, still panting from exertion.
“Thanks, guys,” I said gratefully. I planted a quick kiss on my brother’s cheek before hurrying out of the room to clean myself up.
