Then with the rest of the rope that was bought a had my girlfriend strap my legs over the sybian and stuck to the bed. So that I was the normal way mo...t people ride a sybian except that I was not only 100% not able to move my legs, I also was pressed very hard onto the sybian’s dildo. My girlfriend then also tied my arms behind my back as tightly as she could so that I couldn’t get off until she decided to let me off. I chose to ride a dildo that was about 7 inches long and was a little bit. I took the piece of cloth that had been blocking the drain and held it up and unraveled it to discover a pair of very scanty black lacy panties.I said to Betty "are these yours"? Holding the lingerie up with both hands towards her. She gasped and went scarlet spluttering that they were her granddaughters who had been staying the week previous. I laughed and said to her they were probably a bit too small for her (Betty) and also a bit too scanty. Betty recovered her composure and laughed at my. His cock wasn't that thick at the head but it definitely got much thicker at the base. My hand instinctively started stroking him. The first thing I noticed was the weight, it moved differently than mine. He was uncircumcised where I was circumcised so watching the foreskin slide back and forth over his thick veins really turned me on. My tight cage felt that much tighter now.Excitement, curiosity and the need to please overcame me as I pulled his cock down until it was pointed at my mouth. My. I have to admit that the idea the Nina ended up being just as turned on as we were was a bit surprising to me. We then head up to our hotel room to make our party more intimate. I start to become flustered & nervous since this is my first time I've had any sexual contact with a woman. Sensing my shyness Nina falls back & lets Mark take over. Mark then whispers in my ear that he can't wait to see me enjoy in the pleasure that awaits us. He now has my body laid out & is passionately bringing me.
