When Sis had gotten Charlene (and then me) cleaned of any residue, the three of us lay there for a few more minutes before going in to clean up. Though all of us were tired, and well-satiated from our activities, we still managed to incluse a fair amount of figurative and literal grab-ass along the way.
Once we were all dried off again, The the decision was made that the three of us would all sleep in Sis'
bed; I was delegated to the middle, since both of them wanted to snuggle next to me. With an arm around both of my lovers, it didn't take long for me to fall asleep after all the evening's activities.
The next morning, the three of us went through well over an hours worth of fondling, groping, molesting, and other teasing before reluctantly getting up and giving the house a good going over to ensure it was presentable for when Mom and Dad got back. We also used the opportunity to make extra sure that Evas room got aired out and that there wasn't anything incriminating anywhere else.
Mom and Dad got home as expected (after Charlene had left), and were pleased to see that Sis, Charlene, and I had apparently behaved ourselves.
From then until Sis and Charlene went off to schools, the three of us continued to get considerable pleasure with each other in varying combinations — sometimes it was me and Charlene, or me and Sis; but I was fine with it when Charlene and Sis wanted to have their fun together, too. That I never did anything to interfere or interrupt them was appreciated; enough so that they were perfectly willing to provide the entertainment/stimulation to get ME going.
Nobody in our school ever did find out what the "real deal" was with Charlene, even though she ultimately became as much a part of everyday school activities as everyone else.
That was all several years ago, and I've graduated college and got my own wife and kids (one of each) now. Just as my parents did for me, I've done the best I can to bring them up with open minds, well-rounded personalities, and good characters — and made sure they understood that the could come to.
