Thinking that my son in law might have gone to the mattress, I turned back and opened the door. I saw my son in law standing close to the door. He had...perhaps heard my moans. I think both of us felt a little embarrassed but didn’t speak a word. At night my son in law was sleeping on the mattress besides me. I was hot and started fingering my slit. It felt wonderful having my young hot son in law sleeping besides me. I know I was very wet and was close to orgasm, when I felt my son in law’s warm. "Yes" I told her, "Now it's snack time right Mommy?" in a signal to revert back into our role play."Oh yes sweetheart...now you get your yummy treats!" she said slipping back into her Mother role.I removed all my clothes and lay down on the bed with my head propped up with pillows. Mommy waited until I was comfy then walked seductively towards me. "Are you ready for some more yum-yums?" I was flushed.."Oh god yes Mumma." She giggled at this, and saddled up her thick ripe thighs over my. I actually thought I had something wrong, so I continued to get undressed down to my Speedos. I then quickly ran to the water to cool off, the water was like ice against my chest.After my refreshing swim I came back to my towel and laid down to get some sun, again I noticed the blonde looking at me. I lay down and pretended not to notice. I slowly drifted off to sleep when all of a sudden I felt a cold drop of water fall on my chest. I opened my eyes and there was this blonde standing over me. Shit! Same with my office.” She went quiet again, seemingly in deep thought. Then she went on.“Do you have a car, and do you park in our garage?” I told her that I did. I thought I knew what she had in mind, having witnessed her recent escapade. It worried me, and I tried to talk her out of it. I told her, “If you have in mind what I think you have in mind, we have to be careful. There must be many people coming back from lunch. They will be all over the place.”She took my hand in hers.
