Marte's Challenge No. 2

A few weeks after surviving the challenge of wearing my shell in the restaurant, I was given another challenge. This one was a little bit more to my liking because it involved others except for me and it wasn’t in public. I invited Cindy and Terra over to my house for dinner on Friday night. The mood was upbeat and fun. The girls were still talking about the last challenge and how great it was. Being a few weeks removed from the challenge, I was able to laugh and joke with them about it.

“Just remember girls. Paybacks are hell and you will get yours in the end.” I retorted to their poking fun.

“You can’t give us anything that we either haven’t done before or wouldn’t enjoy!” Terra responded.

“I don’t know about all that!” Cindy said. “But I know Marte couldn’t think up anything to get us back because that isn’t her line of thinking.”

I responded, “I can too think up some good challenges for you girls. Besides, I can get some help from my friend on the Internet. He has lots of good ideas for challenges.”

“So when are you going to do another challenge Marte?” inquired Terra.

“Tonight” I responded, “that is part of the reason you two are here.”

Terra started clapping. “I am so excited. Tell me what the challenge is this time. Are you going to streak through town?”

Cindy laughed. I simply gave Terra a death look for a few seconds before saying, “No! This challenge isn’t in public. This challenge involves the three of us and the shell.”

“So what exactly is this challenge and how are we involved in this challenge?” asked Cindy.

Terra added, “Yeah! I don’t recall us saying we would participate in this challenge.”

“Would you girls like to try the shell?” I asked.

Terra immediately stood up from her seat and said, “Are you serious? I have wanted to try that shell since the day you wore it in the restaurant.”

I explained that the challenge was for me to wear the shell and let them watch me have an orgasm. When I was done then, I had to watch each of them have an orgasm wearing it. I have to admit this was a little bit easier challenge than the last one, but it was more of a reward for doing the last challenge. I did have some fears about this though. First of all, even though they had seen me have an orgasm in the restaurant, I was holding back and they couldn’t touch me because of being in public.

Tonight, there was no one to stop them from touching me if they wanted to. Also, they were going to watch me masturbate with nothing on but panties. They had never watched me actually masturbate before. Secondly, I was going to have to watch them wear my shell and have an orgasm also. I had never watched or seen either of them have an orgasm before so it was a little bit intimidating, but at the same time I thought it would be exciting. Also, I wasn’t a big fan of sharing toys.

We entered my bedroom and I undressed. The girls were kind to me as they joked around to keep the mood fun and playful. I pulled out the shell and swore I could see the girls drooling. My nerves began to kick in as my natural shyness took over. I slid the shell inside my panties then pulled off my shirt and removed my bra. I was now standing before my two best friends with nothing but my panties on. My face turned red with embarrassment.

I lay down on the bed and turned the shell on low. I was nervous and all I could think about was how my body was reacting and what they were seeing. I felt really awkward. I was sure that my body moved different than everyone else, including both of them. I was also afraid that they would laugh at the way I moved after this was all over with.

I lay my hands on my stomach and softly caressed my skin around my navel as the shell began to rev up my engine. I looked at the girls and their eyes were intently watching me with a look of awe as they sat silently. It was as if they were in a trance.

A few minutes passed and I was getting more aroused; my insecurities began to fade. I no longer wondered if each move I made was embarrassing. My hips began to rotate as I could feel my wetness building. My clit was beginning to throb. My hands moved slowly up my stomach, awakening the nerve ending. I rested my hands on my breasts a few second then I began to play with my semi-hard nipples. I closed my eyes and began concentrating solely on my pleasure. The girls made a few comments about how cool this was and how it looked like I was enjoying this so much.

I began pinching and rolling my nipples like I did when I would masturbate on my own. I turned the shell up to medium speed and moaned as the extra vibrations began to manipulate my body and soul. My legs lifted and then straightened out as I wiggled all over the bed. I let out a few moans as I pleasured myself. My breathing was now getting hot and heavy. I could feel my wetness turning into a puddle as my body filled with electric vibes.

“Ohhhhhhhhhhhhhhhhhhh!” I exclaimed as I rocked my hips. I wanted more pressure against my clit so I reached down and pressed the shell harder against pusssy. The shell vibrated my entire pussy. I could feel the vibrations of the shell around my inner thighs now. It felt as if the vibrations of the shell were running through my entire body.

“MMMMMMMMMMMM. Ohhhhhhhhhhhhhhh”

I was getting close and I knew it wouldn’t take long before the shell took over my body. It felt as if the shell molded to me and we became one. My hips were bouncing off the bed as heat overcame my body. I turned the shell up to high and began moaning and whining as a ball of heat began rolling towards my pussy. The nub inside me stimulated my inner walls, which were clamping down. My body danced all over the bed as I resumed twisting and pulling at my nipples.

“Ohhhhhhhhhh yesssssssssssssssssssssss! Ohhhhhh God. I am gonna cummmmmmmmmmm.”

My body began to shudder as the waves of heat over came me. My hips thrust off the bed. My head was dizzy. I let the wave of ecstasy over come me as the orgasm hit my body. My body locked up and I let out a series of long moans. When the orgasm subsided I turned the shell off and lay there, worn out for a minute or so. When I opened my eyes I noticed that both Terra and Cindy had already stripped all their clothes away except for their panties. I saw a look of lust on both of their faces.

“That was absolutely fantastic. The most erotic thing I have ever witnessed.” Cindy said with a smile on her face.

“No doubt! That was sexy as hell.” Terra added.

Terra moved from the edge of the bed up to me and gave me a big, long kiss before releasing and saying, “My turn!”

We all laughed at her impatience. I took the shell off and washed it in the bathroom before handing it to Terra who was already lying on the bed. I noticed that I had left a large wet spot on my bed as usual. Terra didn’t seem to mind though as she lay right beside it. Terra was already playing with her breasts, which were larger than mind. Her body looked fabulous and sexy. She was very athletic and always stayed fit. Her Native American complexion glowed under the bedroom lights.

She turned on the shell and began moaning almost instantaneously. “This thing is awesome. I am going to have to get one of these for myself.”

I never thought that it would be exciting to watch another person play but I was finding this very erotic. I sat on the corner of the bed, opposite Cindy and watched as Terra’s hips began to rotate. I watched her chest raise and lower as she became more and more turned on. There was something about the beauty of women’s bodies that seemed so erotic, even more so when they were in a state of arousal.

Terra turned the shell on medium and I watched as her body writhed in pleasure. She was pinching and pulling at her thicker, yet shorter nipples. I was beginning to become aroused all over again as I listened to her quick, short breaths and watched her body dance. It was as if her body moved in fluid motion. As I watched I noticed that her body moved much the same way as mine did and I realized my actions aren’t that much different then any other woman’s actions. Terra’s moans became more and more frequent and I could tell she was getting very aroused. I don’t know why but I wanted to touch her glistening, naturally tanned skin.

I watched intently as Terra’s hips began to thrust. She placed her hand against the shell and began humping it with all her might as she let out several long, deep moans. One moan followed after another and her hips began bucking as her upper body twisted and turned. I was sure that she liked the idea of having an orgasm in front of others.

I looked over and noticed that Cindy was massaging her clit with her fingers through her panties. She was already very turned on as evident by the wet spot in her panties. I knew it must have been torture for her to have to watch two girls writhing in pleasure as she waits her turn. Terra let out a grunt that echoed off the walls as her orgasm came upon her. I couldn’t help but smile as I watched. Terra’s body dropped onto the bed and she lay motionless as her chest move up and down with her heavy breathing. I could feel my clit beginning to swell again.

Cindy and Terra switched places as I went to wash the shell off again. As I entered the bathroom, I couldn’t help but see what her juices tasted like. I ran my finger over her juices and placed my finger in my mouth. I reveled in the taste of her delicious female juices. I didn’t know what came over me. I suddenly felt very embarrassed at my boldness. I couldn’t believe what I just did. I wrote it off as being very horny as I washed her juices off the shell.

As I re-entered my bedroom I was hit by the strong odor of sex. I hadn’t noticed it as much when I was in the room but upon re-entering it hit me like a brick. I felt my clit twitch with a pang of excitement as the odor of sex entered my nose. I handed the shell to Cindy and said, “Enjoy.”

She grinned and replied, “Oh I will. I am already so turned on from watching both of you. I know it won’t take long for me.”

We all laughed as she turned on the shell. Cindy was a little bigger built than Terra and I. She had a little extra meat on her bones as I always put it. Cindy had much bigger breasts than me, hers’ being size D. Her breasts seemed round and smooth like a melon. I watched as she closed her eyes and turned the shell on. Her hips began dancing right away.

“This is damn sexy watching you girls get off”, Terra commented. “I am doing all I can not to help!”

It didn’t take long for Cindy’s breathing to pick up to a quickened pace. I looked over at Terra and she was fingering herself. She had pulled her panties to the side and reacted to her heightened state of horniness. I wasn’t sure which one to watch. I had never seen a woman finger herself before and it was very arousing. The movements and sounds of Cindy's body also intrigued me.

I continued to watch both of them, turning my head back and forth every few seconds. My body was now all fired up again. It was very erotic watching someone else receive pleasure. To my surprise I noticed that Terra was now rubbing her clit feverishly as I glance over at her. I looked back over at Cindy who had now turned the shell on high and was thrusting her hips like a piston. I could feel the bed bouncing. Before I knew it my fingers were rubbing my clit as well. I hadn’t noticed that my hands had moved, but they must have taken on a mind of their own in my high state of arousal.

Terra, unable to control herself anymore moved up the bed and began kissing and playing with Cindy’s nipples as Cindy began moving closer and closer to her own ecstasy. Terra and Cindy were kissing very passionately and Cindy released several moans into Terra’s mouth as her body began moving into override. I watched as Cindy’s body dance erotically on my bed. I wasn’t sure if I should join in or just watch as I fingered myself.

Cindy and Terra continued to kiss a bit as Cindy’s orgasm subsided. After a few minutes of rest we all sat on the bed and talked about how exciting and erotic this was. Cindy and Terra both made the comment that they were going to have to get a shell of their own. That is another story.
