I was amazed at these normally prim and proper ladies who were undressing in front of me, and in my wife's case, fondling me while the others looked on. They were indeed looking on, both Rachel and Amanda were staring at Rita's hand moving over the bulge in my shorts. Rita was smiling wickedly as she pretending like nothing was out of the ordinary. Rachel realized finally that she was supposed to be trying on her new bra, so she slipped it on while making a pouty face and struck a pose like a Victoria's Secret model. We all laughed and clapped at this, but there was still some serious tension building in the room.
Next, Rita said that it was my turn to try something on. She pulled a dress shirt and slacks out of a shopping bag and motioned for me to try them on. I looked questioning at her and then down at my obvious bulge. She smiled that same wicked smile as before and motioned for me to proceed. I slowly stood up, causing the tent in my shorts to stick out in a very obvious fashion, and pulled my shorts down so that my stretched-to-the-limit boxers briefs were showing. I took off my shirt, while all three girls watched intently. I put on the dress shirt and then the slacks, though the zipper was challenging in my current condition. I strutted around the bedroom to the sound of applause until my wife said they forgot one part of the outfit. Then she pulled out a pair of blue silky boxers and threw them at my face. I put them on my head, and they all laughed, though the laughter was tinged with nervous anticipation. Then I took off the dress pants and decided to go for it. I carefully pulled down my boxer briefs with my back to the others. One if the girls whistled and I felt someone slap my butt cheek. Before I put the silky boxers on, I turned around, giving them a full view of my erect penis and testicles. The whistling and laughter does down immediately, as all three caught their breath, and Amanda even let out a little cry of surprise or maybe nervousness. I thrilled at the opportunity to show them my goods, and my penis bobbed and twitched, showing my excitement.
My penis is pretty average in length, but maybe a little thicker than average. Either way, it is straight, not curved, with a well-shaped head, and I keep my pubic hair trimmed up neatly. I think it is a pretty nice penis. These girls seemed to like what they saw, judging by their reactions. Even Rita, who has seen me naked plenty of times, seemed excited by the display. After just a few seconds, I pulled on the boxers, but didn't bother with the pants. I lounged back on the bed between my wife and Rachel, making no effort to hide my arousal.
There was definitely an air of excitement, like an energy surge through the room. Rita replaced her hand on my bulging boxers and gave me a squeeze while the others looked on with rapt attention. I looked around to see that Amanda's nipples were poking out the material of her tank top even more than before, and she had a hand resting on her thigh, rather near her own crotch. Rachel's body, still clothed in only her pink bra and sheer panties was against my right side, even though there was plenty of room on the bed. Amanda was beside and somewhat in front of Rachel, so that she had a clear view of Rita and me.
I wouldn't have ever dreamed before today that my wife would act this way, but she was clearly enjoying putting on a show for the other girls. She was every so slowly stroking my erection through my silky boxers, which felt fantastic. It was all the more exciting because we had an audience. Rita leaned over and kissed me gently on the lips. She looked up, seemingly to make sure the others were still watching, and then leaned back over and we kissed more passionately. My breathing became a little bit labored, and then I noticed that I was not the only one. It sounded like all three of the ladies were breathing a little harder as well. I sat up slightly so that I had a little more leverage, and ran my hands up and down Rita's smooth back under her shirt. She moaned slightly, showing that she enjoyed the sensation. After a little more kissing and rubbing, I slipped her shirt over her head, then unhooked her bra and slid it off her arms. She undid the buttons on my shirt and pulled it off.
We continued kissing and caressing, with her stroking my clothed penis and my bare chest and back. I was touching all of her exposed skin, now including her small, firm breasts. I broke off the kiss and slowly kissed a trail down her neck and then between and around her two beautiful boobs. I kissed right up to a nipple and then took one of her hard nipples on my mouth. I sucked and nibbled on her sensitive nipple to her obvious pleasure. Actually the action seemed to be pleasurable for everyone in the room. I could hear Amanda and Rachel breathing hard and lightly moaning, so I glanced over to see that Rachel was rubbing her vulva through her panties and Amanda had her hand inside her thong, all-out pleasuring herself. Both of them were staring right at Rita and me, watching me suck on one nipple and caress the other breast with my hand. All the while, Rita continued to slowly stroke my clothed erection. It is an understatement to say that I found the whole scene highly erotic.
After a few minutes, we could not wait anymore, and Rita and I pulled off each other's underwear. As soon as we were naked, our hands immediately found each other's bare genitals. Soon enough our hands were not enough satisfaction, and we found ourselves getting into position for sex. Rita was on her back with her legs spread wide, and I was kneeling on front of her.
At that moment, I realized that we were about to have sex in front of my wife's sister and her friend. I paused briefly and looked to make sure they seemed okay with it. When I looked at Amanda, she had one hand inside her panties, rubbing vigorously on her clitoris, while the other hand was roaming up and down her body, stopping to tweak a hard nipple, then continuing on over the rest of her body. Her shirt was pulled up most of the way to give her better access to her skin, and her eyes kept closing in ecstacy only to open again so she could watch us.
Rachel was still very close to us, actually she had positioned herself so that she could watch my penis enter Rita's vagina. She had a hand inside her own panties and was breathing hard while squirming around with pleasure. Her eyes never left our lovemaking as I slowly pressed my erection into Rita's waiting hole. The amazing feeling of a tight grip all around my penis, while sheathed in velvety softness is beyond my ability to describe. I knew that in my overly excited state, I would have to be careful that I did not release my load before Rita was ready. Luckily, she was also especially excited, and after only a dozen or so long strokes, her body began to tighten and convulse with an orgasm. That was my cue, so I released my own sexual tension with a torrent of semen. It was the biggest, most powerful orgasm I have ever experienced, and the quantity of semen that I shot deep inside my wife seemed like ten times the normal amount.
Both of us cried out, and then I realized that it was not both of us, but all four of us that were crying out in orgasmic bliss, as the other ladies followed close behind with their own explosions of pleasure. We all collapsed in a heap on the bed, breathing hard.
After everyone caught their breath, we got up and cleaned off. Everyone put themselves back together, but no one felt the need to get fully dressed. We all felt so close and connected to one another during that time that we just enjoyed being together until gradually we all drifted off to sleep. Something like this will likely never happen again, but an amazing memory was made that day.
