Usually Olivia used mundane sexual trivia as masturbation background. Making out with her girl crush. One chick getting it on with two annonymous dude.... Matthew from the student council banging the shit out of Sarah from her class. Olivia’s routine was lying on bed and rubbing her clit to orgasm, sometimes sliding two fingers inside if she felt like being filled up. She had no toys and she never felt like she would be interested in them, as long as she stayed single and a virgin, at least. Now. She rises and quietly packs the remains of their picnic into a large cold box. Then she returns to the sleeping figure of Barbara, stoops down and gently kisses one shoulder."Taxi will be here in 20 minutes, Babs."They dress and pack their remaining belongings, then saunter hand-in-hand down the gravel path which winds through the sand dunes behind Coveta del Pinos.They arrive at the gate to the naturist beach to await their taxi back to Benidorm. Barbara sits on the lid of the cold box,. A year ago I convinced myself that she was having an affair. She stonewalled my attempts to confront her. No explanations. No remorse. No reassurance. No attempts to sooth my feelings or counter my suspicions. Just, "If you loved me, you would trust me" and a defiant stare. I withdrew. My employer offered a transfer to another state and I jumped on it. Two months ago I realized I was only hurting myself by staying away.I found my cock stirring as I looked down her lush body. I had arrived late. However, as soon as I saw mother glance at it I felt the fear of punishment and it softened once more."Stand up David, I've just realised I haven't finished washing you."I stood up and she had me bend over slightly while facing my sister, I jumped as a soapy hand closed around my cock, pulling back the foreskin and soaping the glans. A finger pressed against my bottom hole and I tensed up."Relax honey; mummy just wants to make sure you are completely clean."I relaxed and the soapy finger slid.
