Thinking back over the years, I'm quite sure we always made love when we got back together after having swapped with another couple. During the active times, our playmates came to our house or we went to theirs and usually stayed overnight. They always made love once more before sleeping, too.
We sometimes had threesomes when the husband or wife of our playcouple was out of town. We made love after those experiences, too. I remember one time when our "playhusband" came over at 9:00AM for a threesome that lasted until noon. He left and Mrs. Alura and I crawled back into bed.
It seems to me that, no matter how hot or satisfying sex with "someone different" might be, it has never replaced our need to make love with each other.
