I came hard in Marissa's pussy and flopped down next to her on the bed. Reaching over I scooped out a bit of my cum and began rubbing it into her clit spooning against her and working her into an orgasmic explosion. It was our Saturday morning tradition. After twenty five years of marriage we'd always maintained our sexual activity. And while I could count the number of times she'd come from penetration on one hand, her clit almost always got her off.
I'd fallen for Marissa the first time I saw her. It was at my little sister's high school softball game her senior year and Marissa was team captain. I can still remember seeing her stance, her long blond hair gathered in a pony tail, the sway of her firm D cups contrasting with her lithe slender body as she swung the bat. I had asked her out after the game, and to my surprise she agreed.
We married just a couple months after I'd graduated college. Within a year she had Geo Junior, and a little over a year later the twins. Despite no lack of trying, we never managed another pregnancy, and after several more years of concerted effort and some medical testing it was revealed that my sperm count was in the tank.
Always dutifully enthusiastic about sex she was still a goddess all these years later. We'd both stayed physically active, Marissa with her tennis, and I'd joined a men's pickup basketball league at the local gym. That's where I met Roy. Roy was six foot two inches of ebony intensity on the court, and something about our playing style just meshed. At least ten years my junior he had almost limitless energy and I didn't mind feeding him pass after pass and watching him sink yet another three pointer.
It was after one of our Thursday night games that, he said it was his girlfriend Cora's birthday, and that we should grab a beer with her to celebrate at the local sports bar. I called Marissa and she met us there. Fresh from the tennis club she was still in her blouse and skirt, looking cute as hell.
Roy's girlfriend was a hardbodied blond, medium height with a bit of a wild look, tats in places I could only guess at, and an ass that went for miles. She was a nurse and had met Roy after her divorce and they'd been together ever since. She had a great sense of humor and Marissa and her just naturally hit it off together.
We laughed and enjoyed a couple beers, and decided to make it a regular outing. Roy asked me later where I'd been keeping Marissa. It was obvious that there were some sparks there, and he admitted that he thought she was really hot. I, of course, agreed.
The kids were off to college in the fall and that gave us a lot more free time. Every couple of weeks we'd go out to dinner or have a movie night with Roy and Cora either at our place or theirs. As Summer rolled around, we'd drive down to a secluded riverside beach and sun and swim. I'd remembered biking there as a boy and it was perfectly situated just upstream from some big farms. Out of sight and out of mind.
It was on a hot August day that Cora announced that she'd taken a head nursing position in another city, a big step up that would mean she'd have to move. It was a sad moment, but she promised she'd be visiting as often as she could. Marissa gave her a hug and so did I. Roy, laying on his towel in the sand piped in, saying Cora had made a request, but that it was up to us whether or not to grant her wish.
Looking a little confused, Marissa looked at Cora who looked at Roy who slowly tugged up the leg of his shorts revealing an uncut monster of a cock that was as thick as my wrist and easily two and a half times soft as I was hard. Marissa gasped, wide eyed, looking back at Cora.
"Marissa... You know what would be so hot?" Cora suggested quietly.
Roy pulled his foreskin back revealing the dark head of his midnight shaft as it slowly grew in his hand.
Cora slipped her thumbs into the waistband of Marissa's bikini pushing the bathing suit down to the ground. Without even looking at me, she straddled Roy's now fully erect cock and lowered her slick pussy down onto it with a feral groan. Cora sat down next to me on the blanket and softly took my hand.
Cora pulled me around into a better viewing position. I could see Marissa's pussy lips stretching obscenely to accommodate Roy's cock which glistened with her juices. At first she could only manage a few inches, but Roy patiently let her adjust to his size and she gradually picked up her pace, going a little deeper with every stroke.
Roy had unfastened her bikini top and teased her bouncing tits, triggering her first orgasm. I'd never seen her like this before, cooing and groaning as her second orgasm followed on the heels of the first. She was riding him like a racehorse, her pussy sloshing and squirting as she bottomed out on his cock again and again, lost in an orgasmic haze.
I was shocked and mesmerized watching my wife, her body trembling uncontrollably as Roy railed her hard. Somehow Cora had gotten my swim trunks off and pulling her own cum covered hand from her wetness, she slowly slid her index finger up my asshole as she engulfed my cock in her mouth.
Milking my prostate expertly, I oozed into her mouth in a near constant stream until she'd emptied me and gotten herself off with her other hand in the process.
Roy had Marissa on her back, her arms around his neck, they kissed with an incendiary passion. My wife, the mother of my children, moaning like a bitch in heat, her thighs linked behind Roy's midnight ass. Roy's thrusts were strong and purposeful, making Marissa cum over and over again as he stretched her like never before. I could see the sweat on his back, the way he was arching.
"Cum in me, baby! Cum inside me! Fill me up! Take me!" I heard her beg.
It seemed like Roy came for a full minute, his throbbing cock buried balls deep in her unprotected pussy. Excess cum spurted from around the base of his shaft as her pussy struggled to contain the sheer volume. Nearly passing out as he gave one last thrust just to make sure and pulled his still semi-hard cock from her now stretched and spent hole, which gaped and drooled out a steady stream of his seed.
Cora was a little ball of masturbatory goo on the blanket next to me rocking back and forth in her own zone. "Thank you, Marissa. That was so hot. I'll never forget this." She finally managed.
It was getting late, and the sky was beginning to cloud over. Mostly in silence we picked up our things and headed back to the cars. I couldn't help but notice how Roy's juices made a wet spot on the front of my wife's bikini bottom, or how her fingers would absently touch herself, her eyes cast in faraway dreamy reverie.
I figured she'd want to shower when we got home, but instead she lay on our bed and did something I'd seldom seen her do. She masturbated herself to one last orgasm, her eyes shut tight as her fingers worked her clit and pussy in feverish desperation until she finally exploded.
I let the events of that afternoon percolate for a few days. Figuring that she was working through the mental calculus of what she'd done, and what it had done to her.
"I want you to know, I love you as much as I ever have, if not more." She announced a few days later. "I just feel like we need to talk about it, about what happened, though honestly, I don't know where to begin."
"I don't know. I have a lot of conflicting feelings. It should have been talked about first." I began.
"Cora kept hinting to me over the past few months. I didn't think she'd actually follow through. When I saw Roy's cock getting hard for me, I knew my mind was made up. I didn't say anything because I thought you'd probably say No." She confessed.
"I didn't have time to. You mounted him without as much as a second's hesitation." I pointed out.
"I'm sorry, honey. I got carried away." She said, contritely.
"You begged him to cum in you." I added.
"I know. Like I said, I just got carried away. It was just that good." She admitted.
"You're not on birth control." I continued.
"I'll be more careful, next time." She blurted out.
