Isabel's panties were practically on the floor by the time we got into her room, and we didn't even bother closing the door anymore. My mother was downstairs fucking my uncle in a swimming pool, and for the second time I was about to fill my cousin Isabel with my cum.
"You need to get faster at taking your pants off," Isabel said with a snicker as I struggled to get my cock free.
Isabel had two fingers in her pussy as we greedily kissed, her nipples pressing into my chest.
"I fucked your mom this morning," I said, as though Isabel didn't already know.
"Mmm...hmm...ah.I I hope you have some cum left for me," Isabel said as she sat on the bed, taking my cock into her mouth, which was now rock hard, as she licked the precum from the tip before working my cock head with her tongue.
Isabel sucked my cock like she'd been doing it for a living before sliding back on to the bed and spreading her legs. Her pussy was wet and her lips were parted just a bit, her engorged clit poking through.
I knelt on the floor, grabbing her hips and pulling her pussy into my face, her musk filling my nose, as I began licking gently along the inside of her thighs, making my way to her pussy lips before flicking my tongue across her clit.
"Stop teasing me already. Do you know how fucking horny I am after what I heard today?" she demanded.
I responded by taking her clit into my mouth and sucking, pausing to run my tongue along her slit. I put two fingers in her pussy as I resumed pleasuring her clit. Isabel was moaning in tune with the intensity of my sucking. I could feel her thighs beginning to tremble as I worked her pussy.
"Suck harder...mmm...there....harder...," Isabel moaned as I dutifully followed her instructions.
Suddenly I felt her legs tighten and her pussy pulse on my fingers as her orgasm took hold. I sucked her clit all the way through her climax as I finally felt the tension release from her body and a sigh escape her lips. I finally climbed on to the bed, crawling between her legs and sliding my cock into her pussy.
I began pounding Isabel with vigor, watching her tits bounce with each stroke. My cock sliding in and out with ease. I wrapped my arms around her and felt her tits press into me as we exchanged sloppy kisses.
We continued kissing, my arms wrapped around her as I slid back and forth. After a few minutes, I started to feel my cock tense as my orgasm built.
"Are you gonna cum for me? Fill me up like you filled my mom?" Isabel asked as I continued pounding her. The dirty talk sent me over the edge.
"Yes...yes...now," I said as I buried my cock as far as it would go, pulsing and spurting my cum inside her. After about five spurts I collapsed on top of her, kissing her neck as I caught my breath.
We were both coming down from our post coital bliss when a voice interrupted our soft panting.
"You two are a chip off the old block, huh?" I heard my mother say. We both turned to see her standing in the doorway, naked and sweaty. Her hair was a tangled mess, still damp from the pool. I could see bite marks on her tits.
Isabel and I sat up as my mom approached and sat on the corner of the bed, facing us. Her legs were parted enough to see her swollen pussy, strands of my uncle's cum along her lips.
"So what is this plan of yours, Isabel? You know we can't have Carmen ruining the fun. She's either in or she's out," my mom stated matter of factly.
"Truth or Dare," Isabel said. Both my mother and I looked at her quizzically for a moment before a smirk emerged on my mom's face.
I was still a bit confused. Isabel continued, "She's a horny little thing especially now that your son here has fucked her a couple of times. I bet she's at home right now with her fingers in her pussy just dreaming of his cock again."
"So you play an escalating game of truth or dare?", my mom asked.
"Oh yes. We get her started on simple stuff and within a couple of days Sam will be balls deep inside her in the swimming pool on full display of everyone," Isabel said, as if this was something she had been plotting for months, the confidence of someone who does this all the time, if you didn't know better.
"I'll let you take the lead," I said as I wiped a strand of cum off Isabel's thigh. She nodded.
My mother got up to leave us, a wet spot on the corner of the bed in her place. She paused at the door. "I like this plan. Make sure your mother and I can participate too," she said before heading toward the shower.
I flopped back on the bed, Isabel giving me a sloppy kiss before we both fell asleep for a bit of a siesta.
---------
Amazingly, all of us managed to make it through breakfast without cumming. Isabel made sure everyone was briefed on the plan for when she returned.
"Why can't we just tell her to stay home?" My uncle asked incredulously, looking at Isabel.
"Daddy, please. She is my friend and planned her summer around being here. Don't you want the chance to fuck her?" Isabel asked.
"We'll see about that," My aunt added, before turning to me. "You're mine today," she said as she rubbed her hand along my thigh under the table.
I smirked as I got up to clear my plate, my Aunt rising as well, her robe wide open, her freshly shaven pussy on full display.
"Let's fuck outside," she whispered as she passed me by. I turned back to see my mother and uncle already groping each other, Isabel watching with a smirk on her face.
--------
The next day was a Saturday, with Carmen due to arrive back on the train Sunday afternoon. It was the events of this day that sent the rest of the summer into overdrive.
Isabel and I shared a lazy fuck in the morning, in missionary, as the sun slowly brightened behind the curtains in her room. Neither of us spoke, just gentle moans, before I came all over her tits.
Isabel and I got up shortly after to take a shower, passing my Aunt who was coming up the stairs with fresh sheets for Carmen's room
My Aunt paused, her eyes wandering to my semi-erect cock and Isabel's cum covered tits.
"Good morning to you both. Looks like you need a shower," she said rather matter of factly, but her smirk told the story. "See you at breakfast," she added before passing us by.
Isabel and I showered, massaging each other as we washed, and she no doubt had the cleanest tits in Spain when I was done with her. We toweled off and dressed for a pool day before heading down to breakfast. My mom was just coming in carrying a box of pastries and a shopping bag.
We sat around eating our pastries as Isabel elaborated on the plan to my Aunt and Uncle, who no doubt already knew something.
"You really think this girl is game for all this?" My uncle asked.
"You don't know her like I do, especially now that she's had a taste of cock. Trust me," Isabel replied.
