Normally all kinds of alarms should have been going off in my head but, this time they weren't. I got there found the front door open as she said so... I let myself in. Once inside I spied my GMIL standing in the hall propped up on the wall as usual. Her appearance was really different , she had been to my MIL's stylist and had her hair cut and colored similar to my MIL's. She had even got into my MIL's makeup and tried to copy her. Then she dropped her robe and oh my god she was wearing . I do it all and have to hurry so as not to be in trouble. Mom didn’t say anything, but it looked like she was pissed.We ate breakfast, gave mom a kiss goodbye and off to school we went. And, as always, we stopped just out of site and Mandy said, “You know the rules cunt face. Strip it off and be ready for some fucking and sucking this morning.”I took the few clothes I had on and gave them to her. I was naked in public once again. We started walking once I was naked toward the bus stop where all. I felt almost drunk on it. ‘Kiss me.’ she said in a warm breath. Freed from having to stay on our feet, we fell into a longer, wetter kiss and let ourselves thrill to it. When my fingers slid up her stomach to tease around the edge of her bra, she let out a sweet shudder like nothing I’d ever heard from her before. She moved her hand under my shirt, too, as the kisses ranged farther and farther from each other’s mouths. Before long, we’d slid her bra straps over her arms and I was hovering at. And I heard it going on without knowing it. I was getting horned up thinking I was hearing some prostitute getting passed around and here it turns out to be my wife. I was light headed and hard as a rock. With my ear to the wall I was desperate to hear what was going on. I could make out some guy moaning and others laughing but no sign of my wife. It had quieted down a lot compared to earlier. About 10 or 15 minutes had gone by and I couldn't make out a thing. Just then the door opened.
