A few minutes later, I was on my back, watching my twin sister bouncing up and down on my cock. We learned together within ten minutes that she could orgasm while riding me, and that gave us both confidence that making her orgasm in other positions might just be possible. But feeling her pussy clamp on my cock like a vice as she shuddered through more than one orgasm brought us both joy, as although I loved making her orgasm with my mouth, there’s no greater feeling as man that having your lover orgasm while you’re inside her.
Leaning forward, she was soon begging for her brother to cum inside her again, smiling happily when admitting she loved the feeling of me filling up her pussy. Running my hands down to clasp her perfect little arse, I was soon pumping her hard, Alyssa holding onto the headboard as I was driving my cock up into her.
“Fuck me!” she cried out, “Give me that big cock, brother!”
“Can’t get enough of my sisters pussy already,” I grunted in return. I had a feeling we both got off on the fact we were siblings and fucking each other.
Her breasts were at the right level so I could latch onto one of her nipples to start sucking. That set her off again, crying out loud as there was no missing that she enjoyed yet another orgasm. I’ll admit it was with some relief that her orgasm set off mine, driving my cock into her before I groaned, filling my sister with my cum again. Collapsing onto my chest, I held her tightly in both arms as she was breathing heavily.
Agreeing to have a shower, I was amused that my sister staggered slightly though she turned to face me. “I can feel your cum leaking out of me,” she said excitedly, “So much better without a condom. Might keep the mess to a minimum, but I already know I’m going to love feeling my brother’s cum leaking out of me all the time.”
“You’re naughty,” I retorted.
“Only for my brother,” she stated, kissing my cheek before we stepped into the shower. It was only a quick shower before returning to the bed, Alyssa spooning back against me, amused when she grabbed my hand and ensured I was cupping one of her breasts. “We’ll make love in the morning before breakfast,” she said softly, “And again before we check out.”
She woke me up the next morning by sneaking under the sheets and taking my cock in her mouth. As soon as I was awake, she spun around so I could pleasure her pussy at the same time. After swallowing my load, she sat up so she could practically grind on my face, though I made her gasp when I switched my tongue from her pussy to her arse.
“Ooooh. Does my brother want my last hole too?” she breathed, leaning forward slightly as I continued to tickle her rosebud, “Does he want to plunge his big cock into my tight little arse?”
“I’m not going to lie, Alyssa. I’d love to fuck your arse.”
She glanced back and smiled. “We’ll do that later. Right now, your focus is only on my pussy.”
After riding me until we’d both enjoyed an orgasm, we quickly dressed and headed downstairs for breakfast. I have quite the appetite, Alyssa also putting some food away, admitting she was feeling a little drained after the fun we had the night before. Returning to our room afterwards, we undressed and cuddled in bed until she ended up on her back, gently sinking my cock inside her again.
“Make love to your sister,” she whispered, running her fingers through my hair, “Fill her hot little pussy again with all your hot brother cum.”
“I love how you describe your pussy,” I said.
“Well, I’m not wrong, Nate. I love looking at my pussy in the mirror when I masturbate.” She squeezed my cock as I gently thrust into her. “I’m going to send you so many pictures going forward. Your phone is going to full of pictures of my pretty little pussy.”
By the time we were downstairs to check out, she was whispering into my ear that her panties would soon be soaked with all my cum leaking out of her. The receptionist asked if we had a nice night. “Best night of my life,” my sister exclaimed. The receptionist blushed as my sister took my hand and led me outside. Caroline was waiting in the car park.
“Have a nice night?” she asked as we sat together on the back seat.
“I’m still full of his cum,” Alyssa replied rather bluntly.
“Oh… Can I see?” Alyssa lifted her skirt and pulled down her panties, spreading her legs as Caroline turned around and had a look. “Oh my, you are absolutely dripping with cum, Alyssa. Looks like your brother does cum quite a lot.”
“He does!” Alyssa stated excitedly, “After making love last night, he was still leaking out of me as we went to bed. I loved it.”
Pulling her panties back up, she snuggled into me as Caroline turned her eyes towards me and smiled. “I’m glad you made her so happy, Nate. Sounds like you know how to please a young woman.”
“I think I did okay for a first time.”
“The look on her face suggests you did better than okay, Nate.”
Arriving home a little later, Alyssa was holding my hand as we walked into the living room to find our father and older sister waiting for us. Charlotte rushed to Alyssa and hugged her tightly as my father approached me. Resting a hand on my shoulder, I was a little surprised that he was smiling at me.
“Did you look after your sister, son?”
“Um… Yeah, I think I did, Dad.”
“Good. I know she’s sharing a room with Natalie, but as far as I’m concerned, you’re in a relationship, so if you want to sleep in the same bed, that’s fine. Just be careful around Emily and Crystal.”
“Girl chat,” Charlotte stated, taking Alyssa by the hand and turning to Caroline. “Will you be coming too?”
“Oh, I hope I do cum,” Caroline joked as she followed my sisters.
Dad led me to the kitchen, offering me a beer. We stood opposite each other by the kitchen counter. We sank half a beer each in silence before he finally cleared his throat. “I know you’re not blind or stupid, Nate, so I’m going to level with you. I have no problem with you being intimate with Alyssa, and if you eventually include Natalie, the only request I make is to ensure no-one is left hurt by it.”
“We’ve already discussed it, Dad. We’ll need to talk to Natalie later, but for the moment, I just want to focus on Alyssa.”
“Good lad. Now, what I need to tell you is that I’m intimate with Charlotte.”
“We’re aware, Dad.”
“Any problem with that?”
“Hell no. Charlotte’s obviously been in love with you for years. What does Caroline think?”
“She loves it and loves fooling around with your sister too.”
“Yeah, I’m aware Charlotte’s totally bisexual. I’m not sure if she’s fooled around with any of her friends yet…”
Dad cleared his throat. “Will you be wanting me to share Charlotte?” The question surprised me, and it must have shown on my face. “I only ask because I’m obviously aware of how attractive Charlotte is, and since you’re intimate with your twin sister, I’m only wondering if you’re interested in your older sister.”
“Alyssa is,” I admitted, “We talked about it last night. She’d love to fool around with her older sister. I might be involved, I might not. I figured we’d need to sit down with you and Charlotte, maybe Caroline too.”
“How would you like to experience an older woman?” Raising my eyebrows, he grinned at me. “Not Caroline, she loves you but I’m not sure she’d want you in that manner. But your Aunt Jessica…”
“Only if Alyssa is okay with the idea.”
“If you want proper mature, you could always have fun with your grandmother. I mean Caroline’s mother.”
“Seriously?”
“If Alyssa was okay with it, I think she’d love to have fun with her grandson. Do you think she’s attractive?”
“I mean… Yeah… But you reckon she’d want to fool around with me?”
“It’s something we can discuss at a later date. I think for now that you should focus on your relationship with Alyssa, then perhaps add Natalie to your relationship. If you’re both attracted to her, and she’s attracted to both of you in return, there’s no reason why it can’t work.”
“Is that how it works with you, Caroline and Charlotte?”
“Yes,” he replied simply.
“Seriously, Dad, it sounds like this household could just descend into group sex…”
“Well… Saying that, Caroline has wondered about being shared by father and son.” I felt my jaw drop at the revelation. “She’d love to be double penetrated by us.” I didn’t know what to say to that. I knew Caroline had some kinks, but I had no idea she genuinely wanted me involved. “Son, she loves me, and I love her, but it’s obvious our relationship isn’t entirely monogamous. Same with Charlotte. She’s embracing her bisexuality entirely by fucking her friends.”
“She does?”
