My Crazy Girlfriend: Sisterly Traditions, part 2 - My girlfriend is away, her sister will play. (Erotic Coupling) By DragonLairReads. Listen to the Podcast at Steamy Stories. (continuing) I rolled over the next morning to find my girlfriend, Liv; gone from the bed. I also heard the shower running but it cut off shortly thereafter.  Liv 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. Liv explained; “Maggie, you, and I, are all alone for a whole day and a half?” She smiled harder, “Anything could happen.” “So,” I asked; “That’s different than what’s been happening so far?” “Yep,” Liv said. “because this afternoon, I have to run an errand.” I stared at her. “Ok, I have no problems with doing an errand,” I said. She leaned over and put her nose to mine. "You can’t come,” She smirked. What” I protested; "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 d
