My ex sister in law and I are m*********** partners. No touching no s** she just comes by when she is in the mood for a p*** binge with me. Usually just for a few hours or overnight but sometimes she will come over for the weekend. Weirdly comfortable the way we will cook naked or shower together as if none of it is a big deal at all. The only physical contact is the occasional thing lying next to each other with one of her legs thrown over mine or cuddling after a really good long exhausting masturbathon. Sometimes one of us will ask the other to hold us while we take turns c******. Once she came by unannounced and asked me to simply let her watch me j******* for her. She hasnt done the same for me yet but hoping it gets to the point where we are doing it mutually and are each other’s p*** once in a while.
