His long thick cock pumped in my cunt while my juices ran down his shift and dripped off his balls. It was so hot watching my friends get fucked while...I was getting pile driven. Chuck's cock kept hitting the back of my pussy making me pour more of my cum over his shift with each thrust. I couldn't help cumming like a bitch in heat with all his man meat in me.I was moaning and cumming all over Chuck's cock and he leaned over in my ear and asked me if I liked watching all the fucking while I was. It was late, as we had stopped for dinner first, so Marcy decided we would stay in the suite for that one night. She had consumed a fair amount of wine over dinner and seemed a bit tipsy and even flirtatious. When we got to the room, she wanted to have a night cap before unpacking and settling in. I got two after-dinner cocktails from the minibar and went down the hall to get some ice. When I returned to the room Marcy was seated in the upholstered chair with her feet up on an ottoman. I poured. She also changed her morning routine so that instead of coming downstairs dressed and ready for work, spending only about 15 minutes or so with me, before I left for school, she was more likely to be in the kitchen before me in a silk dressing gown, or nighty, giving me a view of her body. As I say at the time I was just happy for the opportunity to see Mum's legs, or her knickers and bra through a thin robe.The problem with all of this was that the more I used Mum's knickers and fantasised. I touched my cock and slowly stroked it. He started to get faster and pumped me rhythmically. I began to moan as I watched myself getting fucked through the wall by an anonymous stranger. I really got turned on and then I started to fuck him back. I bent forward a little and pushed back against his strokes. I began to moan as loud as I would in a private room. I didn’t care. He pumped against the wall up into my ass faster and harder. The wall was buckling against us. I watched myself.
