I rolled over the next morning to find her gone, but heard the shower running but it cut off shortly thereafter. She came out, wet hair flung across her bare shoulders and her slim torso wrapped in a towel. She smiled when she saw me awake and dropped onto the bed.
"You're always so pretty right out of the shower." I said. She leaned over and kissed me.
"You're such a ham." She said back.
"What's our plan for today?" I asked. She laughed. "What?"
"There are no plans, my parents are leaving for their little vacation and its just us here now."
"So, what are we doing?" I asked.
"Mostly this." She said gesturing to the bed. "Laying around."
"Sounds great." I said smiling.
"It also means the game is about to hit hard mode." She said, her turn to smile.
"Hard mode?" I asked.
"Maggie, you, and I, all alone for a whole day and a half?" She smiled harder, "Anything could happen."
"That's different than what's been happening so far?"
"Yep, because this afternoon, I have to run an errand." I stared at her.
"Ok, I have no problems with an errand." I said.
She leaned over and put her nose to mine. "You can't come." She smirked. "Here, all alone, with just Maggie." She looked down at me, copper hair draping around her face. "Think you can hold on?"
"You, my love, are certifiably insane." I said.
She gave a wicked laugh and kissed me. "You love it." She said.
"I love you." I replied.
Her face fell into a serious expression, "I know it's not your thing, but you are having fun, right?"
"Truthfully, letting myself be tempted by my girlfriend's sister has been a challenge. But you did pick some very tempting bait." I said.
She smiled, "I'm so glad you agree."
I reached up and pulled on her towel, but she held it in place. "Why not?"
"Because my folks are gone dummy. Why do it up here when we can do it somewhere exciting? Like on the couch, where we could be seen."
"You are so right." I said sitting up. She raised up and climbed off the bed.
"How risky do you think?" She asked.
"Depends, do you want Maggie to crash the party?" I asked.
"Good point, I'll dress for furtive mischief." She said pulling out a knee length skirt and dropping the towel.
When her naked, lean body came visible, I climbed out of bed and hurried over to her, running hands over her ribs and stomach. She laughed and leaned back. "I can't get dressed if you're touching me."
"You know I can't help it." I said.
"You don't have to, you just have to wait." She said through another laugh.
I slid a hand between her legs and felt her bare pussy which was already slick. She panted and whimpered when she felt my fingers. I stroked her folds and teased her sliding my finger in and out. She moaned quietly and leaned back against me holding my neck. I fingered her gently, feeling her breast with the other hand.
"Downstairs... we were..." She panted breathlessly, as her hips moved.
I shushed her and said, "Think of this as thanks for yesterday." She looked up at me when I said it and recognizing what I meant, panted and kissed me. Her body squirmed and rocked, and she moaned into our kiss. My finger slid in and out of her wet pussy, dragging across her clit.
She broke the kiss and gasped, "I'm gonna cum..." She started to jerk and shook, moaning through an open mouth, holding on to me as her knees buckled and her pussy leaked down my fingers.
She panted against me regaining her composure. I slid my finger out of her and she sucked all the fluid off it.
"Now you can get dressed." I said, slapping her ass. She gave me a look and grabbed her skirt from the ground.
"What should I wear?" I asked looking through my bag.
"Nothing with a zipper." She said.
I grabbed a t-shirt and workout shorts and put them on. I didn't bother with boxers. Liv had put on a shirt, sans bra, and just as soon as it was on grabbed my hand and pulled me out the door.
We made it downstairs and she shoved me onto the couch climbing into my lap and kissing me hard. On top of me, she reached under her skirt to pull my shorts away from my cock. I lifted up and lowered them to help. She licked her hand and stroked my cock with the wet palm for a moment before angling it under her and pushing down.
She moaned, burying her face in my shoulder, "Oh, fuck," She panted as my cock dug into her inch by inch. She kissed me, crying into the kiss as she bounced up and down starting to fuck me. She bounced faster, jamming my cock into her, barely keeping her moans muffled. She buried her face in my shoulder and groaned forcefully as her butt rocked and bounced.
I heard something and tapped her shoulder. She looked at me and I whispered, "I think someone is coming." She collected her hair and face, reclining on me, my cock buried to the hilt in her. She leaned in and kissed me.
Her mom walked around the corner in a hurry, carrying a bag. "We're going!" She said entering the room. She stopped. "What's going on in here?"
Liv, who was beat red from fucking, made an embarrassed face. "Just a little making out mom," She said bashfully, as her pussy leaked down my thigh. "We thought you were gone." Her mom rolled her eyes. "Keep it PG you two. Alright we'll be back Tuesday!" She said giving me a look and exiting out the front door.
As soon as it closed behind her mom, Liv resumed grinding her slick pussy on my cock groaning through her gritted teeth. I lifted the front of her shirt and palmed her breasts as she bounced.
