When we were done watching TV, it was decided that a little swimming in our small backyard pool was called for -" minus suits, of course. Between that and the sunbathing, Jade was feeling a lot closer to normal by the time we came back inside. When Sis decided that Nadia needed an orgasm to settle her down again, Jade was perfectly willing to assist – and then go on to enjoy a leisurely session of "69" with Sis when the two of them got worked up in the process of getting Nadia off.
Before we went to bed that night, Sis and Nadia had both felt the need for my "invaluable assistance" -" that is, I was the only one capable of providing the erect penis that they wanted to use.
The next day was a lot more relaxed, what with Nadia and Jade planning on going home in the afternoon. I had Nadia on my lap while Sis and Jade groped and kissed during the morning TV programs; after a nice swim, we were all comfortable with just laying around and listening to music; Sis and Nadia snuggled, as did Jade and I.
When they were ready to leave, Nadia and Jade both made sure I knew they were sorry to leave. Jade's kiss told me just how much our lovemaking meant to her.
Mom and Dad got home to a clean and organized house, reassuring them that nothing too drastic had happened in their absence. Both looked happy and relaxed, making Sis and me glad that they'd been able to have a good time. Both of us knew how hard they worked, and how much time and effort they put into taking care of us.
With the start of school again, the four of us easily got into the familiar routine. Some of the faces that we'd known were gone, replaced by people that were new to our school or town. All of us made a new friend or two, and continued our various activities whenever the opportunity presented itself; I was able to make love with Nadia and Jade often enough to keep them reasonably happy, and with Sis often enough to make me happy. The school year ended with Sis and me in the top one percent of the school, academically -" something that made Mom and Dad even more proud of us.
