I clench my jaw to stop the groan I know she wants to hear. I move our joined hands from her breast, twirling her around to face me. I pull her tight ...gainst my body, still rocking my hips back and forth, My thigh slips between hers. I change the rocking of my hips to making a wide circle, pressing my cock against her mound. Her head falls back, her passion-laden eyes staring up at my face. I lower my head to brush soft kisses over her lips. Her head follows mine when I pull away, trying to. I sucked her toes and ran my tongue along themas she began to massage my dick with her other foot faster and moreviguously. She leaned back in her chair and moaned, apparentlyenjoying herself. Seeing my Mistress so pleased had a weird effecton me. My arousal heightened and I came all over her stockingedright foot. At that instant she caught all of my seed on her footand then swung her swivel chair around so that her right foot wasby my mouth also. "Finish the massage," she said quietly. I. .. you know that. Linda..." Nikki had tried to hold her but Big Sis promptly removed her sister's hands from her waist. "Linda, why are you like that? I'm trying to help you." Don't!" was the answer. Then Big Sis walked away from her, going to the opposite side of the waiting room.Outside, in the parking lot, Nikki stared at another incoming ambulance, its flashing lights rotating, the screaming siren dying down. Swiftly the paramedics leaped out of the ambulance and scrambled into the building. The cabin was almost as clean as our house. I felt a little chagrined at suspecting that the two women would have spent the morning making love instead of cleaning.Lunch was sandwiches and iced tea. I wolfed down my share and part of the girls too."Now that Max has recovered from yesterday's lessons it's time to pick up where we left off. Let's get washed up before we start though. Max is sweaty from chopping wood and Alice and I need a nice bath, too. Let's make it quick though, we have a lot.
