"Your turn, Brad." Mary told me. I peeled my shirt off; I then slowly unbuckled the belt on my jeans, and undid the buttons on the fly one at a time, revealing that I wasn't wearing any underwear. I let the pants fall to the ground, and my hardening cock rose to attention. I pointed it at my wife and said, "You and Jack have to undress each other."
Donna walked over to her brother, and rubbed her hands on his chest. While she did this, Jack began to undo the buttons on Donna's blouse. Slowly, Donna pulled the t-shirt over Jack's head, as Mary and I sat on the oversized couch. After his shirt was removed, Jack took off his sister's blouse, and unhooked her bra. Donna let it drop to the floor, revealing her bountiful DD-cup breasts. Jack then unzipped the denim skirt Donna was wearing, and it fell to the floor, revealing Donna's ass and shaved cunt. Jack and Donna began kissing, and as Jack's hands explored his sister's body, she stopped him. "You still have clothes on," she reminded her younger brother. Donna then fell to her knees, and pulled Jack's shorts down to his ankles, freeing his swollen cock. But she didn't stop with that. She took her brother's member into her mouth, and began to suck on it, and massage his balls.
Mary was inspired by this and began to do the same to me. I watched as Jack closed his eyes, and moaned with pleasure at his sister's oral ministrations. I too was enjoying Mary's attention. Mary used both hands to pleasure me. She rubbed my balls with one hand as she sucked on me, and slid the other one under my ass, and slid a finger in my anus with the other. I could barely reach her twat, and began to search for her clit.
Meanwhile, Donna was really going to town on Jack. His knees had buckled and they got into a sixty-nine position. Donna really loved being eaten out, and I knew that Jack could do wonderful things with that tongue of his. It wasn't too long before they both orgasmed. The intensity of their pleasuring was just too intense to sustain for long. Jack tensed up, and I cold tell that he was cuming in Donna's mouth. She could barely contain it, but Jack pulled out and splashed his sister's tits with a fountain of his cum.
Hearing them orgasm sent me to the peak as well. Mary held on however, and swallowed every drop of my spunk. I told Mary that Donna needed to be cleaned up, so we both got off the couch to where our spouses were and began to lick Jack's semen off Donna's tits. Donna had presented a breast to each of us to clean off. I licked a bit off my wife, and leaned over to Jack, and kissed him on the mouth, presenting him with a bit of himself. He took it readily, and he searched without looking for my cock. He wrapped his hand around it and began to stroke it back to life. I moved a hand down Jack's chest, and found his cock, still hard, and I began to lightly stroke its shaft.
Jack then repositioned himself so that we could blow each other. I looked over at our wives, and they were basically doing the same to each other. Having sucked Jack's cock before, I knew what his limits were, and I teased him with my tongue. While I did this, I noticed a bottle of astroglide, and condoms on the coffee table. Jack looked at me and winked. He got off me and went over to the table and got two condoms, and the lube. Jack said, "Since you're the guest, do you elect to give or receive?"
"On your back with your ass in the air, buddy," I said. Jack did so, but after he put a condom on my cock. I put a generous amount of lube on my hand and slicked up his ass crack, I then put the rest on my sheathed cock. As I slowly penetrated Jack's ass, Mary and Donna had gotten a couple of vibrators, and were now using them on each other.
I slowly worked my cock in and out of Jack's ass. I put his legs over my shoulders, and began to jerk him off with my slick hand. Jack closed his eyes and moaned with pleasure as I filled him with my cock. After a few minutes of stroking his cock, and ramming his ass, Jack's eyes flew open as his cock erupted like a volcano, splashing cum over the two of us. With one final push, I came as well, my cock pulsing and emptying itself into the latex barrier. We stayed as one until my cock shriveled and was pushed out of Jack's ass by his sphincter.
We watched our wives pleasure each other. They were in their own world, caressing, licking, pinching, and suckling each other. I looked up at the television, and realized that Jack had the video camera recording all that was going on in the room. I began to get hard at the thought that I could see what we all looked like together. I noticed that Jack's dick was rising from the dead as well. I whispered, "You want to fuck me, or them?"
"I'll get you later, I want Donna's cunt," Jack said as he stalked the ladies on all fours like a predator. He got behind his sister, removed his wife's face from her cunt, and thrust himself inside Donna. Donna gasped at the surprise fucking she was now getting. I went over to Mary, and pulled her out from under the two of them, and kissed her, and worked myself to her breasts, and sampled each one. "Brad, I love you, but I want your cock in my cunt NOW!" Mary exclaimed.
Not being the type to deny a lady of her desires, I rolled Mary over and began to fuck her doggy style. We both love this position, because I can really go deep inside Mary. It didn't take long for us to find a rhythm that we both enjoyed. As Jack pounded away at his sister, I did the same to his wife. Almost on cue, we all orgasmed simultaneously. As we collapsed, to the floor, it was me that noticed Rachel standing at the doorway, with a shocked expression, but her hand in her shorts.
"How long have you been standing there?" I asked.
"Not too long, just from where you finished fucking Dad," she answered. All heads snapped to the doorway. Rachel definitely has a swimmer's build. She's been a competitive swimmer almost all of her life, and her trim 18-year-old athletic frame was something that I had tried my best not to think about. Her hair was a short length brown like her mother's but straight, and her breasts were slightly larger looking than Mary's. Her t-shirt clung to her body because it was wet, and her nipples threatened to burst out.
"What are you doing here, Rache?" asked Mary. Rachel told us that the meet had been cancelled because of the thunderstorm at the pool where the meet was being held. It had also knocked out the power at her friend's house, so she came home. She heard the noises we had been making and investigated.
Donna stood up, and walked over to Rachel. "Get those clothes off; you're going to freeze with that on," Donna told her niece as she pulled the t-shirt off of her. I was right, her breasts are slightly larger, and I knew this because like her mother, she wore no bra. Donna began to pull off Jess' shorts, and Mary started to object, but Jack stopped her. "Let her decide for herself what she wants to do," he whispered to his wife.
Now naked, Jess walked into the room to where the rest of us were. She got on the floor with us and asked, "Can I join you?" Mary said yes, and reached for her daughter, her hand brushing one of her cheeks, and slowly moved down her body. Mary asked, "Have you ever touched a guy's penis?"
