His cock was getting very hard as he grew to a full, long, thick erection. Peni and I started rubbing our tits together and running our hands over eac... other's shaved pussies. We were both ready for some action, but she was in charge. We rinsed off, got out of the shower, and dried of waiting for her next instruction. There was a king size air mattress on the floor and several bottles of oil. Peni directed dad to lay face down on the mattress.Peni position herself on one side of him and me on. ..it felt so good, his arse burned deep inside and he felt a little pre cum ooze from his head.He couldn't stand any more and gripped the metal rings around his cock slowly moving up and down as the bit into his skin, he knew he couldn't last long and started to work harder bringing his hand hard down onto the top of is balls. He worked it for a couple of minutes while he rocked on the plug, the deep sensation driving him to new heights. Just as he felt his balls tighten he stopped and watched. "Yes Martha?"

The only thing he did was to tell Lisa to always wear above the knee skirts or dresses with stockings not panty hose.Class went on as usual for the rest of the night. After the class was over Steve could not wait to see how she would be dressed tomorrow.The next day Lisa came home from work at the health club to get ready for class. After she showered she started to get.
