This is very interesting... in fact, I am 22 weeks pregnant and my husband and I were fairly new to swinging when I did get pregnant! The third time we were with a couple that we had been playing with, I got pregnant. Now, although it was what we consider "group sex", I did not actually have intercourse with the other man. Therefore, I know my husband is the one who did the "job" so to speak... ha ha... and he did come inside me with no condom. We discussed how we were somewhat relieved that there was no official penetration from the other guy. If there was, then a condom would have been necessary. But still... the thought in the back of our heads would have been there... asking if maybe it was him... When we first found out though, we discussed it in detail and we would have assumed that the baby was my husband's, not the other guys.
The other couple does know I am pregnant. I don't know if they put 2 & 2 together and realize that the conception happened when we were with them. We didn't bring it up and they didn't ask. I don't think they were concerned about it and we have no worries either. We have stopped "playing" with them and everyone till we are done with the pregnancy and the baby is born and are trying to be patient...lol. It's good to fantasize though!
