Ellie went rigid instantly, too much in shock and disbelief to move.

And ever so slowly, she turned her face to the other side and her eyes widened as she realized her big sister was right there.

Cherys was all soothing angel, rubbing Ellie's cheek.

“That was incredible." Cherys' eyes glittered in awe.

Ellie let a satisfied smile spread across her face. "It felt incredible. But I don't know if I'll be able to sit down for a week."

"C'mon, Little sis. Let me clean you up.”

I stayed right in my position as Cherys helped Ellie slowly dismount my bed. She pinched her butt cheeks together and used one hand to try and stem the flow from exiting down her Legs, with only partial success.

Ellie did stop and lean to me.

“We will DEFINITELY do that again sometime." And then she planted a sloppy kiss on my lips. In that moment, my mind was a jumble of disbelief at what we had done, shock that our siblings were present, and warm love for the young woman who had shared such a vulnerable part of herself with me. Ellie shared a significant look with me, giving me a little smile. Then gingerly,

Ellie stumbled out, helped along by her big sister as they headed for the bathroom.

Danielle darted in first and came back with a wet washcloth just as the shower started running. Without caution she reached down and started cleaning me off with the washcloth, her hand moving back and forth in a wraparound scrubbing motion. The sudden feeling caught me off guard and my back went stiff.

Her hand never actually came into contact with my skin; it was on the other side of the washcloth. But only when my body tensed up did

Danielle seem to realize she was touching me in a very intimate manner.

“Oh! Ohmigod. Well, uh," she dropped the washcloth into my lap.

“I guess you can do that yourself." And only now did she realize her nakedness. In sudden embarrassment, she tried to cover her breasts and crotch with her hands.

I suddenly felt bad, like I'd caused her this mini-pain. "No! No! You just surprised me. I... I didn't mind you cleaning me. Felt kinda nice, actually."

But the damage was done.

“Yeah, well. Anyways, I'll... just go back to my room." And with that she fled.

I watched my sister's tight ass as she half-ran away. And then I looked down at my crotch to resume cleaning up a bit. The damn thing was already hard again.

Well, I would have a lot of pleasant memories and visuals to keep me company on any Lonely nights.

The next two weeks of winter vacation passed in a somewhat similar manner. Cherys and Danielle would occasionally venture out to visit with old friends. Ellie and I would hang out with our own high school friends as well. But other than that, much of the daytime was spent at home in varying stages of arousal.

The sibling relationships also changed during those couple of weeks.

Cherys and Ellie had always been friendly enough with each other. But

Cherys' sexual orientation had always kept her slightly aloof from her family, who accepted it only with some reluctance. But ever since that day she and Danielle came in on me and Ellie, the sisters had formed a more comfortable bond.

Maybe something happened in that shower that I don't know about. In the end, I never found out. Unfortunately, while I had a happy boyfriend-girlfriend gig with Ellie, we were nowhere near as tight as
