Their hands began roaming all over each other's bodies. Cindy's fingers had worked their way up under Julie's shirt and were reaching into her bra and finding those big 36D tits. I knew she had found them by the familiar gasp Julie gave when playful fingers hit her nipples. Their mouths still locked on each other, moaning and writhing together. Julie began returning the favor to Cindy by grasping at her tank top and squeezing her young 18 year old perky tits. I couldn't believe I was watching Julie and her best friend in a full on groping and kissing session. I had dreamed of this for a long time, but never imagined it would be happening. By this time, my cock was rock hard and pressing hard against my jeans. Julie whipped her shirt up over her head and Cindy's young pouty lips were firmly grasped on her nipple suckling it like she was a baby. Julie moaned as Cindy's lips and tongue made love to her nipple. She looked over at me and gave me that lusty look she gives me when my lips are doing what Cindy's now were. I could take it no more....
Watching these two go at it was like having my own little lesbian porno movie right there in my living room. I unzipped my jeans, but my eyes never left the two of them. I pulled my stiff hard pole out from my jeans and wrapped my hand around it as the two of them continued tasting and fondling each other. I started to groan and stroke my cock watching my girlfriends nipples get licked and sucked by a pro. Suddenly, Cindy was pulled out of her lusty trance and remembered that I was in the room with them. She looked over at me and realized that my dick was now out and being pumped by my fist. Now I know that the two of them talk about everything and I know they must have at some point talked about my dick so I'm thinking Cindy seeing it for the first time won't be that much of a surprise for her. She took one look at it and shouted "Holy Shit!". Julie shoved her tits back into Cindy's face as she reached down and took a firm grasp of my cock. Cindy's mouth on her tits had gotten her into such a frenzy that she now wanted Cindy AND my cock at the same time. Cindy hungrily lapped at Julie's tits, but couldn't keep her eyes off my dick.
As I watched the two of them, I could feel myself getting closer and closer to finishing. "You gonna cum baby?" Julie asked in her horny voice.
I nodded and she guided my cock in between the two of them. Not caring where it was going, I let Julie aim me at whatever she wanted. Watching Cindy lick and suck her tits put me over the edge. Spurt after spurt shot out onto Julie's tits. White hot sticky cum jolted from my cock and onto her juicy glistening tits. Cindy hungrily lapped up every squirt as it landed on her big tits. Julie squeezed out every last drop and Cindy loved every taste of it.
I had never known either one of them to be bi or bi-curious, however this event changed my whole view of both of them.
