I just nodded. We picked up our towels and headed upstairs to the bathroom. I turned the water on while Shelly put our towels in the washing machine. I wasn’t sure where this was going or how far either of us was prepared to go, but I was still pretty wound up and open to seeing what might happen.
I stepped into the shower first and moved to the back, allowing Shelly to step in front of me. She rinsed off her front, then turned around to let the water run down over her back and ass. She leaned her head down and I could tell she was looking at my cock, which was not longer erect, but still very full. It almost looked like she was starting to lick her lips, then stopped. She reached over and grabbed the bottle of liquid soap and poured some over the wash pad and began to soap the front of her body while I watched. Her breasts glistened from the water and soap, and her nipples were still full and erect. As she soaped her body, my cock began to stiffen again and grow. By the time she finished, my cock was arching out in front of me and I could feel my arousal pulsing through it.
Holding the wash pad out to me, she asked if I could wash her back. I took the pad and she turned around. I ran it over her shoulders and back and forth over her back, reaching the top of her ass. I paused briefly and she didn’t move, so I continued lower, running the pad over and around her ass cheeks. My hand was larger than the pad and my fingers ran over her ass as I did this, further exciting me. I could tell she was enjoying is as she seemed to push her ass slightly back into me. I knelt down and continued to work my way down each leg and then back up the other. Shelly stepped back at the same moment I was standing back up and the head of my now fully erect cock made contact with her and traced up the length of her of crack. We both stood completely still for several seconds.
“If there’s enough soap on my back, you could probably just use it to soap your front.”
I placed my hands on her hips and pulled her into me, my cock rubbing up against her slippery, perfectly round ass. She began to move her hips back and forth as our bodies gyrated against each other. I slowly brought my hands up her slides, my fingers hitting the underside of her breasts, then up and over them, letting the tips of my fingers roll around her very hard nipples. She let out a low moan as I did this, pushing her breasts into my hands as her ass continued to rub against my cock. I felt her hand then reach around and slide between my cock and her ass, running up my length, then wrapping her fingers around it. I moved back slightly, giving her extra room as she began to stroke me.
“Mmmmmm, that feels really good, Shel.”
“I’ve been fantasizing about touching it since yesterday, but wasn’t sure I should even try. It just felt like we both wanted it.”
“And I’ve been wanting to touch your body also, but felt the same.”
Shelly turned around to face me, looking down at my cock as she continued to stroke it. My hands were roaming over her breasts and stomach and neither of us said a word while we explored each other. As she continued to stroke my cock, I left one hand fondling her breast as I let the other trail down over her stomach and over her smooth pubic mound. Moving lower, my fingers traced around her clit and over her lips, rubbing gently up and down. Shelly moaned and picked up the pace of her stroking.
She leaned into my ear and whispered, “Do you want me to do more?”
“Yes, but only if you really want to.”
Shelly didn’t answer, but turned us sideways, the spray from the shower running over my cock and cleaning the soap off. She then turned me forward again and moved me towards the back of the shower. She knelt down in front of me and took hold of my cock and leaning forward, licked the tip. Her tongue rolled around it in circles, then she opened her mouth and slid my cock inside, beginning to suck me. My head was spinning. My sister was actually giving me a blowjob and beyond that, it was, without a doubt, the best one I had ever had. She couldn’t quit fit all of me into her mouth, but she definitely took most of my length, her tongue swirling around the shaft as she sucked. She held the base of my cock, sucking me with abandon, occasionally, pulling back and licking up the length of my shaft as she looked up at me.
“I’m gonna cum,” I said nearly breathless.
I wanted to give her the chance to pull back, but she did just the opposite, sucking even harder, clearly trying to pull the cum from my cock. That was all it took and I came again hard, Shelly swallowing without hesitation. She kept sucking until well after my orgasm had subsided. Finally, she released me and stood up, licking her lips and facing me with a wicked look spreading across your face.
“I hope you enjoyed that because I totally enjoyed doing that to you.”
“Fuck yes. That was the most amazing blowjob I’ve ever had.”
“Are you shocked that I did it?”
“A little, but I can honestly say I don’t regret anything we’ve done. It’s been totally amazing and it actually feels really special with you.”
Shelly leaned in and kissed me gently on the lips. “That’s the most perfect reply I could imagine. For whatever reason, it doesn’t feel weird to me either. I just feel really good and totally satisfied.”
“Well, we’ll just need to make sure Mom doesn’t notice anything out of the ordinary, so I’ll probably still annoy you a little around her for show.”
“I bet I can handle that. I’ll just take it out on you later in private.”
“Oh, so there’ll be more when she’s not around?”
“I think our sheltering at home just got a lot more interesting.”
“So, you’re open to us continuing to play around?”
“Are you?”
“Definitely!”
“That’s good, because I’d have a problem if you had said no. There’s still so much to explore. And besides, you owe me an orgasm.”
“Trust me, I’ll be more than happy to make things even. Just so I know the boundaries, do you think we need to stop with oral?”
“Maybe, but I don’t know if I want to. You?”
“Are you one the pill?”
“Yes.”
“Then, I think we can do whatever we want. And I have a feeling I will want to do a lot.”
“Well, I guess we’ll see what happens next. We should probably get dried off and dressed and get everything put back before Mom gets home. And I’ve got dinner to fix.”
I pulled Shelly into a tight hug. We kissed briefly again and then we both broke out laughing. This was definitely going to be an interesting summer.
