Family Gathering

Last March at the yearly family gathering at the beach, I met my sister Rachel 26 friend, Linda 27 and during the party at the beach we ended up fucking behind a sand dune. We both had a few drinks and spend the night together, much to the annoyance of Rachel. Rachel is a lesbian and Linda is more bisexual than a full-on lesbian, anyway, I have started seeing Linda a lot since then and even spent the night with her in Rachel's apartment in bed with them both. Nothing sexual with Rachel, but Rachels wants to keep Linda as her lover and hasn't been trying to stop me and Linda since. I've got Linda pregnant and have asked her to marry me. She accepted and she has asked Rachel to be her maid of honor, also she still sleeping with Rachel. It is not unusual now for the three of us to shower together and Linda wants Rachel to share the wedding night with us. Rachel is still thinking it over at the moment, I don't think I will be able to fuck Rachel. But if the chance presents itself I will.
