Finally, it was Wednesday afternoon February fourteenth: Valentine’s Day! I was driving to the Airbnb I had booked for a very special and romantic evening with Claire. It was expensive but from what I could make out from the photos, it was just what I was looking for. I arrived and with a healthy dose of excitement I entered the code to get access to the small apartment which was just a fifteen-minutes’ drive away from our house.
A happy melody sounded which was accompanied by a loud click. I smiled when I saw the interior of the place. It smelled clean and the huge bed was meticulously made up of freshly washed sheets. The place was simple, but it was perfect for my plan. I quickly unpacked the bag and started to work, making the room look even better. I tested the remote which switched on the decorative lights I cleverly had draped over the room’s shelves and paintings.
A satisfied grin appeared on my face when I remembered showing those lights to Cindy. I had timed it well because our parents had just left for the weekly grocery shopping. We ended up having the most intense fuck I had experienced. It was the thrill of doing it in the limited time we had, and we knew it probably was our last opportunity to be together as lovers. At least that was our agreement.
I checked the time, realizing I had to rush back home to have a quick wash and get dressed for my date with Claire.
I stood next to Claire in the glass lift, enjoying the amazing view over the town. I stared at my girlfriend, and I remembered her father’s preaching about the old days when people just didn’t go out during the week. I had to bring Claire back home before midnight and preferably in one piece. His sense of humor was a little off but now I understood how Claire had developed her strange witty humor.
The door slid open and the pleasant noise of people happily chatting instantly brought me into a much better mood. Claire squeezed my hand as we stepped towards the small desk where Simon’s mother was waiting for us. “Hello Claire,” she said enthusiastically, “how nice to see you together with Casper, especially on Valentine’s Day. Let me get Simon, he will bring you to your table.”
“Thank you, Mrs. Webber,” muttered Claire, totally flabbergasted. As she stared at Simon’s mother strutting away, she asked me, “Is Cindy here as well?”
“Huh?” I responded, shocked because I hadn’t expected Simon to be working tonight.
“She told me she’s having dinner with him!”
“Hey guys,” Simon’s voice echoed from the corridor that led to the kitchen, “Fancy to see her majesty’s special dining table?”
“Hey Simon,” I said while we bumped fists, “I didn’t know you had a royal visitor.”
Simon chuckled and briefly looked at my girlfriend. “Hey Claire.”
She pouted and asked, “Don’t I get a greeting from you?”
“Oh sorry, erm,” he replied while he raised his fist.
“A hug will do,” she said sweetly while she opened her arms.
I laughed when I saw his eyes bulge as he carefully pulled her into his arms. “Nice to finally meet you in the flesh, Simon,” she purred, “I’ve heard so much about you.”
Simon looked at me and I shrugged my shoulders, indicating I had no idea where this was coming from.
“Only good things, I hope,” he responded meekly when he awkwardly stepped away from her.
She laughed. “Don’t worry, Simon. My lips are sealed, so you’re safe.”
He coughed and as he turned towards the kitchen he said hoarsely, “Right. I think Cindy can’t wait to see you guys.”
As we followed him Claire hummed appreciatively. “She’s right,” she whispered, “he does look very cute in those slacks.”
Perplexed, I stared at her enigmatic smile on her pretty face, wondering how often the two women were chatting with each other.
We went through a small door that led into the kitchen and as soon as the girls saw each other they squealed happily as if it had been ages since the last time they’d met. Simon and I looked amused at the theatrical scene of the two women hugging each other. It was Cindy who pulled Claire through the door and said to Simon, “We need to powder our noses.”
“I knew they were friends but,” Simon said a little flustered.
“Uh-huh,” I replied, wondering how close they really were, “I know but I don’t mind. Do you?”
“No, not really. I think they both look hot, especially tonight.”
Simon was right; Cindy and Claire looked spectacular, and I was looking forward to having dinner with Claire. I thought it was strange he had to work, and that Cindy was having dinner on her own. “It’s a pity you’ve to work now.”
Simon checked his watch and said, “Only for another ten minutes. I’m just standing in for Emma.”
I nodded. “Did you plan something special?”
His face got a little red. “Yeah, erm, there’s a bedroom in the private part of the restaurant. It took me the whole afternoon to get it ready.”
I smiled, knowing all too well what he was hoping for. I saw a small box of candles and I suggested, “Perhaps you can take those to the room ... Women like candle lit rooms.”
“Yup,” he replied, grinning from ear to ear, “I’ll use all of them.”
I stopped the car in front of the Airbnb and as I killed the engine I said to Claire, “I really enjoyed dinner. It was fun to eat dessert together with Cindy and Simon.”
She laid her head on my shoulder and said dreamingly, “Yes, that was nice. But I still can’t believe you gave me the ring. It’s so beautiful.”
I took her hand and let the ring’s small diamond glisten in the streetlight. My uncle was a jewelry artist and we had worked together on the design. I only had to pay for the diamond which still caused quite a dent in my savings, but it was worth it. Cindy knew about it, of course, and it pained me seeing her trying to hide her envy.
I kissed Claire’s hand and said huskily, “If my lady is in for a small drink, I would suggest we move our dainty butts to a more cozy place.”
She laughed. “Who says you have a dainty butt?”
“Alright,” I conceded. “Let me rephrase. If my lady is in the mood for a drink, I would suggest you move your dainty butt.”
“Hmm,” she murmured, “I don’t know. You’re nice and warm.”
“I know, but I want to be closer to you than only your head. And it will be a lot more comfortable.”
“Okay,” she sighed. “If you insist.”
I knew she was fucking with me and as a gallant man I helped her out of the car. I was pleased I still remembered the code to unlock the door and when I guided my sweet girl into the apartment, I used the remote to switch on the lights. Claire gasped when she entered the room. “Oh, this is so beautiful,” she gushed when she saw the rose petal heart shape on the bed.
I pulled her into my arms and said softly, “Happy Valentine’s Day.”
“Oh Casper,” she cooed, “I love you.”
My heart was beating in my mouth because it was the first time, she said the ‘L’-word. It took me by surprise, and I knew she would always be the second woman I loved. “Love you too.”
Those words were heartfelt and as I gently rubbed her back she whispered, “Make love to me.”
Claire’s naked body looked fantastic in the soft lights, and I would’ve liked to shower her body with soft kisses, but I could see in her eyes she wanted something different.
“You’re always pleasing me first,” she said when she traced her finger over my pecs. “Let me please you, this time.”
I couldn’t deny it; I loved to bring my lovers to an amazing orgasm, especially because I knew exactly how to do it. But her plan actually did have merit because I definitely would last a lot longer after I had an orgasm. Claire sat up and eagerly roamed her eyes over my body and let her hands slowly travel down south where they started to massage my rigid member. Her hair tickled my stomach when she placed soft kisses on my skin. Only once she had given me a blow job in the shower, where she let my cum blast onto her pert breasts.
I moaned when she engulfed my cock into her hot mouth, knowing I wouldn’t last long because it felt so amazing. Only then I realized she was copying what Cindy normally would do to bring me to an orgasm quickly. It was sweet because she lacked the flair and boldness Cindy possessed, which made it even more special. It totally overtook me by surprise, and I barely had time to warn her, “Oh Claire. I’m about to come.”
It was clear she didn’t mind that I would blast my load into her mouth because she intensified her magnificent onslaught. It was those moments that I knew men were just as vulnerable as women, desperately needing their release. Claire pressed a finger just under my balls and that instantly triggered my orgasm. I roared while I bucked my hips, imagining I was filling her womb with my cum.
Claire looked tired but satisfied when I took her to the front door of her house. She pulled me into a hug and kissed me tenderly on the lips. “Thank you, Casper. I had a wonderful evening.”
My cock started to thicken remembering our hot love making. After she had gotten used to having her pussy stretched by my girth, she was on fire, and I was sure the neighbors must have heard her howling. It was clear my cock wasn’t the first foreign object that had entered her silky depths. I was convinced a hefty dildo was hidden under her bed, and it had been regularly used. I didn’t mind because it gave us the opportunity to solely focus on us. “I’ve loved every minute of it, Claire.”
She chuckled while she pressed her hips against mine. “Uh-huh,” she cooed, “Next weekend my parents will be on a golf trip. I’m pretty sure I can fit you into my busy schedule.”
I laughed. As I slowly shook my head I whispered in her ear, “I’m looking forward to it, my little temptress.”
“Casper?” she asked, her voice suddenly sounding a lot more serious.
Slowly I pulled away, concerned that her pretty face had an almost guilty expression. “Hey sweetheart,” I said soothingly, “what’s wrong?”
“I’ve never told you that Cindy goaded me to be friends with you.”
“Ah, I see,” I said while I tried keeping my face as neutral as possible. “I think a good spanking should be sufficient.”
She squeaked softly while her body became rigid. “I’m sorry.”
“My sister has been very naughty,” I deadpanned. “A few slaps on her butt should be enough.”
“Oh! You!” Claire exclaimed while she playfully slapped my bottom.
“Got ya,” I said grinning, “but I definitely will thank her for her foreseeing advice.”
“She is an astonishingly smart woman,” Claire affirmed with a warm voice.
Her words made me think about Cindy and I knew she was right; my sister seemed to whizz through all the subjects without fails. Her self-esteem had improved enormously after her ‘problem’ was solved, which made her even more desirable. My heart skipped a beat when I looked at Claire’s gray eyes. They had changed in color, which made her look even more mystical. I cupped her face and pulled her in for a searing hot kiss. I needed to make her feel I was her man, her lover, and her friend. Her soft whimper was what I wanted to hear, knowing she was affected by my attempt to blow her mind.
