The sun shined brightly on the old, but still seaworthy 26-foot-long cabin cruiser. There was hardly a cloud in the sky. It was a perfect day for diving off the coast of Florida.
"Guys, this demand valve isn't working right," Matthew announced.
His large bicep flexed, but still he couldn't adjust the dial on his scuba equipment. He frowned and said, "I noticed it acting up on the last dive. I'm done for the day."
His fiancée responded, "Oh no." There was a pause and then she added, "I'll sit out with you."
It pained Eve to pass up a dive. She really loved diving. However, she and Mathew were getting married in a month. She thought, "Soon I will be standing in front of family and friends, promising to be with him in good times and bad. I guess that means sometimes you have to pass up on an activity you enjoy if your partner can't participate".
"Nonsense Eve. You have to go. I know how much you've been looking forward to this and besides, your brother needs a dive partner."
"Okay, honey."
She beamed and thought, "Lucky me. He's handsome, smart and nice".
"Lunch is ready," Sally announced as she stepped out of the cabin. She passed out bags of chips and sandwiches. Her husband gave everyone a drink. It was juice for their two kids and beer for the adults. As he handed a cold one to his sister, Adam teased her saying,
"Don't tell Mom I gave you a beer. I don't want to be charge with corrupting a minor."
"Har har," Eve said. "I'm eighteen and legal. Get used to it. Your little sister has grown up."
Adam glanced at her well-formed, bikini clad body and thought, "Yes, you have. Mathew is a lucky man".
After lunch, Sally waited until she and Eve were alone in the cabin. She shut the doors and then asked, "Can you do me a favor?"
"Name it," Eve said without hesitation. She really liked her brother's wife. She thought of her as the older sister she'd never had.
Sally smiled and said in a conspiratorial whisper, "I need you to look after the kids for a bit. As you know, today's your brother's 25th birthday and I owe him a birthday blowjob. I want to surprise him by doing it here in the cabin."
Eve's jaw dropped. She was shocked that her sister-in-law was telling her about her sex life.
Sally continued, "Don't look at me like that! Married people have sex. I love my husband and I like having sex with him. Your brother is a very skilled and considerate lover."
"Ugh!" Eve made a face. "Too much information!"
Sally sneered at the eighteen-year-old and said, "You're acting like a silly little virgin."
Eve blushed. She hesitated and then confessed in a quiet voice, "Well, as a matter of fact, I am a virgin."
"Oh, Eve! I'm sorry I said that. That was mean of me. Matthew is so handsome and I know you love each other. I assumed you were sexually active."
"We do stuff," she admitted embarrassed. "My mom told me my virginity was a special gift to be given to a special guy. No one I've dated seemed special until I met Matt. He was impressed when he learned I was a virgin. It was his idea to save intercourse for our wedding night."
Sally hugged Eve. "Oh, that's so sweet. He's a great guy."
Sally pulled back, grinned and teased her sister-in-law saying, "So that explains the short engagement."
"Yes! I'm so ready."
Sally continued to tease her friend. "So I'm not the only girl in this cabin who likes to suck cock?"
"No," Eve replied reluctantly. She was embarrassed. It was hard for her to admit that she was having sex, but harder still to confess that she liked it. She added. "I'm sorry if you thought my reaction was a put down of you."
"You made me feel like I was a slut for wanting to give Adam a blowjob," Sally said with a sulky pout. She was acting, acting well, and her accusation had the desired effect. Eve looked crestfallen.
"I'm sorry. I think you're great."
"Well . . ." Sally paused for effect and then said. "There's only one way to make it up to me. Dish on Matthew. Is he well-hung? What do you like best about his junk?"
Sally gave Eve an impish grin and egged her on saying, "Friends share."
Eve sighed. She really liked Sally. She felt closer to her than to any of her school friends and girls do talk about this stuff.
"Okay," she gave in. "His penis gets really hard and big."
She held up her hands giving a visual aid to how big he gets. Then she turned her hands palm's up and she mimed holding large balls.
"He has huge, low hanging balls. When he comes he gushes gallons. I can never swallow it all. It spills out of my mouth and drips on my boobs."
"I knew it. He is a manly man," Sally said impressed.
The women smiled at one another. That was a real bonding moment for them. Sally felt it was her turn to share.
"You're getting married soon. Let me pass on a piece of advice my mother gave me about having a successful marriage, "Be the woman he fell in love with".
"Time will take its toll. Kids and events will make demands on you, but remember to continue to do the things that brought you together.
"I insist we have "Date Night" at least once a month. We still make out in the car and smooch on the sofa just like when we first dated even if the kids think it's "yucky". Having sex with each other is something we've always enjoyed. It strengthens our bond so we do it regularly.
"Be that fun flirty girl that caught his eye. There are days when I "forget" to wear a bra. On a "nothing special night", I'll break out the sexy lingerie. We give each other things to look forward to. Come Valentine's Day, I know I'm getting roses from the man I love and he knows come hell or high water, I will give him a special blowjob on his birthday. He looks forward to it and so do I."
"Okay, but why on the boat?"
"Doing the same thing, the same way, in the same place is BORING! Mixing things up keeps it fun. He'll never expect this."
Sally unhooked her bikini top and tossed it aside. Eve grew slack jawed. She always knew the blonde had a nice set, but she'd never seen them before. She was surprised the twenty-six year exposed her orbs so nonchalantly. Sally chuckled and said,
"Honey, we know guys like boobs. Adam smiles and salivates every time he sees these "saggy because I breast-fed your two kids" tits. Why not let him have his fun? He's a good man. Now go out there and tell him there's a problem with the toilet and he has to come down here immediately."
Sally winked at Eve and sent her on her way.
Adam pushed open the cabin doors and said, "So what's wrong with . . ." He stopped mid-sentenced when he saw his smiling, bare-breasted wife.
"Hello, Birthday boy," Sally said exuding sexuality. "Ready for your present?"
Adam looked at his wife and hurriedly closed and locked the doors. He whispered, "What? Here? Now?"
Sally licked her lips and pulled on a thick, engorged nipple. He watched it snap back. She then said, in a not so quiet voice, "I want some cock."
Adam was nervous. He felt like the whole world could hear her. Sally walked over to him and started unbuckling his belt. Soon she had his shorts and underwear on the floor. He had a shit-eating grin on his face as his wife dropped to her knees. She licked the length of his growing shaft. She kissed the crown and then hefted his balls.
In a little girl's voice, she said, "This was supposed to be a present for you, but I think you have something for me. Are you going to shoot a big load of nasty cum in my mouth?" She batted her eyes precociously and added, "Should I swallow it?"
Adam's head nodded like a bobble head figure mounted on the dash-board of a car speeding down a bumpy dirt road. His dick sprang to life. He quickly grew to full mast because his wife had surprised him with the offer of a blowjob and was flashing her bare tits at him. The bawdy role playing was a turn on too.
"Oh, my gawd!" He groaned as she enveloped his cock.
She was not a reluctant cocksucker. Sure, Adam going down on her was more fun than her going down on him, but she liked giving head. Even though they were married, she still got a thrill being the naughty girl who would suck a dick.
Eve and Matt corralled the kids and involved them in a game. Eve had the misfortune of dropping a pretzel at the same time a big wave hit the boat. She leaned over to pick it up, the boat lurched and she got tossed to the deck.
By chance, her head was near a cabin portal. She looked inside and got a side view of Sally and her brother. "Oh my!" she said to herself. "There's Sally topless, on her knees sucking on my brother's dick. I shouldn't be seeing this."
Adam had his eyes closed and a big smile on his face. He loved the fact that his cock was in his wife's mouth. He said, "I love you, Sally. I love your birthday blowjobs. Ahhh. Thanks, this is great."
She said brightly, "You're welcome."
His wife returned to sucking, licking and stoking his prodigious member. Then she swallowed him deep into her throat. When she released him to breathe, she and Eve locked eyes.
Eve could feel her face turning red. Sally stroked Adam's dick and mouthed "So Big". She even held out the penis so Eve could get a good view of her brother's erection. Then she showed off her skills by plunging it back into her throat.
"Are you okay Eve?" Matt asked as he helped her up. "You look flushed. Sit and rest. I'll take care of the boys."
Eve nodded thinking "Sally must think I'm a pervert because I spied on them. Some weird Peeping Tom who wanted to see her brother's penis. Oh God! I've never been so embarrassed".
Sally returned with love and vigor to pleasuring her husband. She pumped his shaft and suck his hard penis until he again cried out, "I love you!"
His dick exploded and forceful jets of sperm flew into her mouth. She milked every last drop out of her husband. She showed him a mouthful of viscous ejaculate, swallowed and then showed him an empty mouth.
"Oh Baby, you're the best" he gushed.
