It was still so amazing to realize I was doing these "dirty" things with my brothers. I was so turned on by the entire incest concept. I loved feeling so uninhibited with my brothers. I enjoyed them looking at my naked body with lust in their eyes. It was such a turn on, knowing that my tits and my puss excited them and made their dicks hard!
Alan's dick was throbbing in my mouth, as I sucked and licked him. Slowly I would lick my tongue over the head of his shaft, then down to his balls, then back up again, where I would suck the head into my mouth with loud slurping sounds. As I continued working on Alan's dick, I felt Robbie move close to me. His hand found it's way underneath me to caress my big tits that were swaying back and forth. His other hand began caressing my plump ass.
I could hear Alan moaning as I sucked him and Robbie was moaning as he played with my tits and ass.
"Oh sissy, I love your big titties and your big ass" Robbie groaned. "I like watching you suck our brother's dick too."
I felt Robbie's hand move between my legs, spreading them open. He moved his hand so he could reach between my pussy lips. He spread them apart and found my pussy hole. I was already so hot and wet.
"I want to play with your pussy, sissy" Robbie told me. " I want to finger your cunt."
All I could do was moan since my mouth was full of Alan's dick. I moved my ass toward him giving him an invitation. As I did that, I felt him insert two fingers into my pussy hole. I humped backward to receive them. It felt so good! Robbie began working his fingers in and out of my puss and I began to suck Alan in rhythm to it. Robbie was very close to me and I could feel his dick rubbing against my leg. I moaned loudly when I felt it. I needed it in my pussy so bad!
Robbie must have realized my need. He removed his fingers from my cunt, and moved behind me. I knew then, he was going to mount me. We were going to do it doggy style!!!
"Sissy, I'm going to give you some dick! I'm going to fuck you like a doggy!" Robbie said as he spread my legs and moved between them. He took his dick and pressed it against my pussy lips as he mounted me. I was eager and opened up for him. I felt his dick head against the entrance to my pussy hole. With one hump, he pushed it in and filled me with his big dick!
I had raised my head from Alan's dick for a moment and cried out in ecstasy.
"Ohooh! Ooooh! Robbie, fuck me! Mount me and fuck me like a doggy!
I cried out. "Yes! It feels so good!
"Sissy, suck me, suck my dick!" Alan begged. "I'm going to cum Sissy. Keep sucking me!"
I returned my mouth to Alan's dick sucking it hard. I felt him throbbing and I knew he was going to shoot his wad soon. Robbie was fully penetrated in my pussy and was humping me slowly. That gave me time to suck Alan off.
