First time for everybody

Isaac had no idea what he had done to deserve this, but he was not questioning anything at this point. Two beautiful young women had him on his back on his new bed. His shirt was practically ripped off and tossed aside, baring his torso to them. His body was slightly toned from helping his family with physical labor around the house, but nothing special. These two had surely seen a lot, and he doubt he ranked high on any list. However, the didn't slow down at all. Once his chest was bare, the twins, in unison, each latched on to one of his nipples, teasing and biting them. If his cock could get any harder, it would turn into literal steel.

Mandi kissed her way up his neck, but as she reached his chin, he put his hand up and stopped her. Her sudden pause confused her, and Brandi as well.

"What's wrong?" questioned Mandi, afraid she had done something wrong.

"Are you okay?" inquired Brandi, concerned that something happened.

"I'm fine, really! I just... this is... well, it's my first time with a woman, so..."

"Oh my god! No way!" they both almost screamed in tandem. They looked at each other with adorable expressions before again speaking simultaneously, "Aww!! That's sweet!"

They both leaned down next to his face, looking at him as if he were a puppy. Isaac felt embarrassed by this kind of attention. He was now afraid that he ruined the mood and missed his chance. His fears were crushed as the two looked at each other, and Brandi gave an approving nod. Mandi sat up and looked into Isaac's eyes, staring at him for a moment before closing her eyes and pressing her lips to his. This caught Isaac by surprise, having never kissed a girl before. After a moment of hesitation, he began to kiss her back. Her lips were plump and soft, feeling like kissing a cloud. When she pulled back, their faces were glowing. It was Mandi's first time taking a boy's first kiss, and it was Isaac's first kiss ever. Brandi giggled at the two acting so cute!

His kissing cherry popped gave him more confidence, grabbing Mandi's head gently and pressing his lips to hers suddenly. She was caught off guard this time, but pleasantly so. Her return kisses grew in intensity, as did Isaac's. Mandi took charge again, her experience being her guide, and she slid her tongue into his mouth, playing with his. His eyes grew wide at this sudden intrusion, but then filled with determination and returned the favor. Moans of approval filled the room as these two made out for the first time. This continued for a few minutes until Mandi pulled herself back, smiling from ear to ear. She turned to her twin sister and invited her to try it herself, taunting her with, "Your turn!"

Brandi wasted no time jumping on him, diving her tongue into his mouth. Brandi was certainly more aggressive, but not without expert technique. She pulled back from the kiss and bit his lip, a sultry smile spreading across her face. Isaac pulled her back into a fierce make our session, this time surprising her by sucking on her tongue and bottom lip. Brandi pulled back, having to get her breath back. This unexpected skill took her breath away, for the first time that she can remember. It was her turn now; he grabbed his nipples and gave them a firm twist, causing her plaything to arch his back in a strange mix of pleasure with a tinge of pain. His squirming caused Brandi to smile with a slightly sadistic glee; she enjoyed being in control of his pleasure!

Oblivious to Isaac, Mandi had a thirst that must be quenched, moving her hands to his belt, undoing it and tossing it aside with haste. She wanted her own toy to play with while her sister had her fun. She grabbed the waistband of his pants and boxers at the same time, pulling down with reckless abandon. Isaac felt a dull pain as his steel manhood sprang forth, freed from its cloth cage.

"OH. MY. GOD! HOLY SHIT!!"

Brandi and Isaac immediately stopped and looked down at her with great concern. "What is it? What's wrong?" Isaac asked, starting to worry that something happened that he couldn't see.

Brandi turned around, still on top of him, and shared her sister's bafflement. "What the fuck!? What the hell is that??" Her near scream caused a great deal of panic in Isaac, now trying to push Brandi aside to see what the problem is.

"What? What is it?" Isaac almost shouted, pushing her harder to the side. Finally she moved out of his view, down by her sexy twin next to his dick. He now realized what the commotion was about. "Oh... Is something wrong with it? Is it too small? I hear guys worry about that all the time, but I have no basis for comparison..."

The twins looked at each other for a moment, stunned. "Small?? Are you kidding me?? This is the biggest thing I have ever seen!!" Mandi's excited amazement reassuring Isaac now. "How were you hiding this thing?? It... its incredible... but it does scare me a little..."

Brandi jumped off the bed and began digging through some bags and drawers in the room, until she triumphantly grabbed something and returned to the bed. She placed a ruler she found against his pelvis, checking the length. "You can't be serious... is this fake? No way... This thing is almost a foot long!! What the fuck??"

Isaac was very unsure as to what to think right now. Was this a good thing, or a bad thing? Should he be concerned, or see a doctor? "Umm... Is it ok? Should we stop...?"

Brandi laughed a little at this suggestion. "Stop? Oh no! I am going to take this beast!!" She grabbed the flexible ruler and wrapped it around this monstrous member before her. "Good god... Will it even fit? This may hurt..." She tossed the ruler aside, and then just stared at this new challenge she has accepted. "Eleven and a half inches long, with seven inches in girth... Mandi, I need some hell with this!"
Isaac tried to object, but was quickly silenced by Mandi's hand on his mouth. "Shh. Just relax. We know what we are doing!" She shot him a wink, and put her hands on this magnificent cock. "Okay, Brandi. I will start. You sure you can take it?"

"I should be asking you the same thing! You won't be able to breathe with that in your throat!" They both giggles a little at this. "We should be dressed appropriately, dont you think?" She asked her twin with a wink.

They both stood up and started stripping in haste. It was now that Isaaac realized they were each not wearing a bra. He watched these two incredibly sexy women strip naked in front of him. The sight of their bare breats and waxes puppies made his rock hard manhood jump in anticipation. They both looked at it, then gave him the same sultry smile. Isaac swallowed hard; he was in for one hell of a night!
