"Whooo," Darius said, as Mary released his rapidly growing cock. "If you kept touching me any longer, we were about to have a problem."
"Not a problem she couldn't handle" Amy said while winking at Mary.
Jeff noticed Mary turn bright red and smile at Darius in response to the remark.
Amy continued, "And Darius doesn't seem to be the only one turned on" as she looked at Jeff's fully erect 5.5" penis and locked eyes with him with a smile while softly biting her lower lip.
Despite her boyfriend' massive cock, Jeff couldn't help but feel Amy was hitting on him.
Amy crawled over to Mary's towel with her tits swaying beneath her and began whispering in Mary's ear. She pointed her ass towards Jeff and her pouty pussy lips were on display. Despite the secretive nature of their conversation, both men enjoyed the view of two beautiful nude women talking and snickering together like schoolgirls. Mary grew quiet and nodded while Amy continued whispering. Amy finished and left Mary's ear.
Mary turned to the men, "I think we need to reapply sunscreen, don't ya think?" Mary said.
"That's a good idea, honey," Jeff said as he reached for the sunscreen in the bag to lather her up.
"Wellll, I was thinking Darius could get my back," she said, the blood rushing to her face, awaiting Jeff's reaction.
Jeff paused momentarily. "My prim and proper wife wants a large muscular black man to rub sunscreen on her petite pale white body," Jeff thought to himself.
"Umm yeah, that sounds good... I guess" Jeff said with slight reluctance in his voice.
"Jeff, don't forget about me. If Darius is preoccupied then I'll need a hand," Amy said invitingly.
"Don't have to tell me twice" Jeff said with a smile as he made his way over to Amy with the sunscreen.
"You can start with my front actually" Amy said as she rested on her elbows showing off her full tits to Jeff.
Jeff couldn't wait to get his hands on her perky breasts. He warmed the sunscreen in his hand and applied it to her titties. Her nipples were hard and he made and every effort to pinch them as he slowly massaged the sunscreen into her chest.
Jeff couldn't believe he was getting to put his hands on Amy's hot young body. Her breasts were easily a D cup by Jeff's assessment. She had quarter sized areolas and eraser thick nipples. The thought of what Mary might think of him massaging her breasts didn't cross his mind as he was so transfixed on Amy's body.
As he worked the sunscreen lower, Amy parted her legs revealing her smoothly shaven pussy. Her labia was significantly more pronounced than Mary's and Jeff had the urge to lick it. At this point his cock is back to fully erect and oozing pre-cum at the sight of the beautiful woman before him.
Jeff had a thumb on her clit when her heard a soft guttural moan.
"Mmmhhmmm."
It was Darius...
Jeff snapped out of his trance and looked over his shoulder expecting to see Darius rubbing sunscreen on Mary's backside.
What he saw was not at all what he was expecting. Darius was beside her on his knees. Mary was in a pseudo sit up position resting on one hand and stroking Darius' big black cock with her other. Meanwhile, Darius was cupping her pussy and pinching one of Mary's small nipples.
Jeff couldn't believe how long each stroke was from the base of Darius' shaft to the bulbous head of his cock. Jeff guessed Mary could easily fit three fist lengths on his cock. Meanwhile, Jeff's cock wasn't long enough for just two.
Jeff realized he had forgotten about Amy and looked at her. She was also staring at the erotic sight and gave her breast a tug. Realizing she wasn't disappointed by his abrupt halt to the massage he looked back to his wife.
Copious amounts of precum were oozing from Darius' cock. To Jeff's shock, Mary leaned her head towards his monstrous cock and gave the underside of his shaft a long lick, lapping up much of the precum.
Darius, recognizing how the situation was developing said, "I think we should move somewhere a little more... private."
Without saying a word, Darius and Mary rose to their feet, grabbed their towels, and began walking toward the sand dunes; her eyes locked on him the entire time.
Jeff, realizing how out of character it was for Mary, expected her look at him to "check in" .... but it never came.
Jeff's stomach sank at the sight of Mary's voluptuous ass swaying as he she walked away with Darius, hand in hand.... But his raging boner remained.
He felt a touch on his shoulder.
"Don't worry" Amy said, reassuringly to Jeff. "He knows how to take care of her."
"I don't know what to feel," said Jeff. "I feel like I should be angry and jealous, but I'm not."
"That's because you know, deep down, you want Mary to be pleasured and Darius has... skills you don't possess. You just love her so much you want her to experience true sexual satisfaction."
"I mean, she doesn't cum from penetration and even clitoral can be an issue. Maybe you're right," Jeff felt better, maybe she could use a different man's "technique" as Amy called it.
Mary and Darius had now disappeared behind the dunes.
"She we follow them?" Jeff asked.
"Let's give them a few minutes first. You being there might make her nervous, and she needs to be totally relaxed."
"Relaxed for what?" Jeff said confused.
"For Mary to be able open up to take all if him."
Jeff's stomach sank again but he was more turned on than ever before.
"There's no way Mary would... fuck him," he thought to himself.
....
After several minutes of silence Amy rose to her feet and began walking towards the dunes.
"Are you coming or what?" she said, looking back at Jeff as she walked.
Jeff quickly rose to his feet and followed Amy's juicy ass to the dunes. Amy approached the dunes, stopped, and waved Jeff to catch up. As Jeff approached her hiding place behind tall grass at the base of the dunes,
Mary and Darius came into view. It was nothing Jeff had ever expected to see. Mary was licking Darius' cock from balls to tip. She had both hands around his cock, with plenty of length to spare, and was sucking his cock furiously.
The sinking feeling in Jeff's stomach returned at the sight of his wife devouring Darius' enormous cock. His reserved wife was sucking the big dick so ravenously it was as if she was sex starved teenager.
To be fair, she'd never seen a cock this big in her life. Despite Jeff's feeling of inadequacy and jealousy, he remembered what Amy told him. "She deserves to feel good," Jeff thought to himself.
"Don't worry," Amy said as she approached Jeff from behind and lightly touched to his back. Jeff looked to her, speechless, and Amy continued, "He knows his way around women, especially ones that are new to this."
"New to what?" Jeff asked.
"Big cock, silly" Amy replied. "He has a ridiculous talent for getting tight girls to be able take him."
