I awoke to the sound of someone knocking on the door. My eyes were barely open and all I could think was that my room-mate was out all night, and was trying to get in early in the morning but forgot his key. Then I heard the knocking again and mom's voice, saying, "Are you awake, Danny?"
It was then that I realized where I was; I wasn't in my dorm room at all. I had spent the night sharing my sister's bed and having the greatest sex of my life with her. I still find it hard to believe! I took a quick glance around the bed, and room in general, to make sure everything looked in order. We were far enough apart to appear innocent so I answered, "Yeah, mom, come on in."
Mom could see that Chrissy was still asleep so she whispered, "It's nine o'clock; I don't know if you set an alarm but I thought you might want to get up soon. Dad and I are going to take grandma and grandpa to the diner for breakfast; did you want to go?"
"Nah," I replied, as Chrissy began to stir, "we'd never get showered and dressed in time anyway. You go and enjoy yourselves; we'll fix something here after we get up."
"Okay... by the way, the turkey's in the oven and needs to be basted in about an hour."
I told mom I'd take care of it and threw off the blanket before getting out of bed. I felt a bit confused about the previous night. I mean, my sister and I had experienced such fantastic sex as a total surprise and it felt great. But now, I didn't know how I should conduct myself with Chrissy. I mean, do I hold her and kiss her and whisper how terrific it all was, like I might do with some girl from college that I spent the night with? Or, should I just act cool and try to downplay it? Was she going to regret it now that it was over and be pissed off at me?
I went into the bathroom and relieved myself before turning on the shower and letting the water get hot. I stepped inside the tub and felt the spray pour down over me; man, did that feel good! I turned myself around so each part of my body received the hot streaming water.
Suddenly, the shower curtain parted and Chrissy stepped into the tub with me. She nudged me aside and let the water run all over her body, and the long brown hair flowing down around her shoulders, before grabbing it in both hands and neatly arranging it behind her back. She then stood in front of me, wrapped her arms around my waist and pulled me close, tilting her head and planting her soft, full lips on my mouth.
We kissed for a long time before she broke it and backed away enough to look in my eyes and say, "Danny, if what you gave me last night was brotherly love, I think I'm gonna move to Philadelphia!"
Well, so much for wondering what direction our relationship was going in. I had to chuckle at her use of the "City of Brotherly Love" to make her point. I told her, "I don't know what to say or how to explain what happened last night."
She thought for a moment, then replied, "Danny, I don't know how it happened either, but I do know that we both enjoyed it and I don't think either of us regret it. So, let's not complicate matters by trying to analyze it, okay?"
With that, she grabbed the soap from the wall ledge and handed it to me, saying, "How about washing my back, bro?"
I took the soap and worked up a good lather as Chrissy turned her back to me and I began spreading it over her skin, starting with her neck and shoulders and traveling down her back to her butt. I marveled at the beautiful shape of her ass and thighs. My cock was beginning to stiffen at the sight of her wet, naked body. She then turned to face me again and asked, "Wanna do the front, too?"
I gently ran my soapy hands from her neck, over her upper chest, and then around the sides of her gorgeous breasts before placing both hands over the front of her tits and feeling the nipples with the palms of my hands. I looked straight into her eyes as the water dripped from her forehead past her lashes and down her cheeks; my hands traveled lower, rubbing the lather over her taut stomach.
I stood back a bit and eyed her magnificent body, her full breasts glistening with the soap film and water droplets. Even without makeup, her face was beautiful, like that of a glamour model; I said, "Chrissy, you are the most amazing girl I have ever known!"
My cock was rock hard by now and my left hand rested on her waist as my other one gripped the soap and dipped lower, completely covering her pussy and rubbing the lather into the trimmed patch of hair above her slit. The wet bar of Dial suddenly slipped out of my hand and fell on the floor of the tub. Chrissy turned around to find it and then bent over to pick it up. I stared down at her butt and said, "Whoa...hold that pose, Chrissy."
I took my hands and parted her beautiful ass cheeks slightly. Just below her bung hole, I could see the tender folds of her labia and I moved them apart with my fingers. My hard prick was sticking straight out and I moved forward a bit so my cock head was able to enter her wet snatch. Chrissy stayed bent over like that as I eased my shaft all the way into her warm pussy, the hot shower water beating down on her back.
I was all the way into her tight love tunnel and fucking her with slow, even strokes as I leaned over and reached under Chrissy's body to grab her tits; they hung below her chest and swayed forward and back as I humped her from behind. My cock was fully enveloped by the walls of her vagina as I slid it back and forth; it grew harder with each push. I squeezed her soft, full breasts and played with the nipples as Chrissy started fingering her clit. I continued to increase the speed of my thrusts and I knew she was getting close to her climax.
"Ohmygod, Danny... I am SO READY... I'm going to cum... right... NOW!"
Chrissy started breathing really hard and fast, squealing uncontrolably as the rush overtook her and her legs weakened. The intense feeling centered in her groin quickly traveled in a wave throughout her body. She held out her arms to support herself by leaning on the edges of the tub as the feeling slowly subsided and she began to regain her composure. She needed to stand up so I pulled my slipperly rod out of her hole and began stroking it slowly as her breathing returned to normal.
