I sat back on the couch to watch.Medium would be able to bring her to climax, but it would take a while. I sat back on the couch to watch. For a hal... hour she stayed strong, complaining moans coming through the gag every now and then, and then consistently as her pussy grew wetter. Then they started, barely noticeable at first, but slowly more apparent. Her twitches as the vibrator started to get to her. Every few seconds at first, trying desperately to pull herself away from the pleasure. ?Yes, Miss.? ?Bladder and bowels ?? ?Yes, b ? both, Miss.? ?Excellent.? She stepped back. ?Bladder first. Hurry.? Gemma shut her eyes. After many minutes controlling herself, she couldn'tjust go straightaway. The pit in her belly rumbled and her bowels ached forimmediate release. It was difficult to loose her bladder without relaxing herbottom at the same time. Eventually, though, she felt her urine coming. ?Open your eyes. Look at me.? She obeyed and watched the young woman watching her.. A heavenly feeling. Irub my hand up and down my thighs as I watch this young man fondle hisgrandma's ample breast with one hand.....and feel the guidance of his grandma'shand stroke her clit with the other. He leans into her shoulder and rests there,savoring every sensual moment. My own arousal is peaking at watch them.She continues to guide him with her hand and before long she has herselfshuddered and sighed very softly....making me think she has cum. It was such asight to see...her grandson. "OHHHHH F F F UCCCK!!!!" I screamed as I climaxed one of the best climaxes of my life, I felt his hot cum shoot inside me and I heard him groan. He slumped his body over mine as we Tryed to catch our breath. "this.. Was.. The best.. Tutoring.. Lesson ever" he said still getting his breath back. "you're right. We should do it more oftend him groan. He slumped his body over mine as we Tryed to catch our breath. "this.. Was.. The best.. Tutoring.. Lesson ever" he said still getting his breath.
