My son freed me from my dysmenorrheal pain. I forget my pain and remain in that position. He shoots my crotch from beneath the glass table. When he sa...w my panty soaked with blood, he gave me another panty to change. I happily obeyed. However, due to my motherly instinct, now I turned back, pulled down Thong, and cleaned my crotch with it. I know my son is intently watching my butt.My butt was also an object of desire to him in childhood. When he was 5-6 years old he run into kitchen, catches me. So she slips his cock into her pussy anytime he wants, which is apparently all the time. Duke and Tiff are insatiable. He will get hard again sometimes right after fucking and she is more than happy to fuck again right away. There have been days where it seemed like they literally fucked straight through with no breaks at all.Guys, I haven't even told you the worst part yet: night time. At night Duke is allowed to sleep in our room, including on the bed. Sometimes I wake up to what feels like. In that instant she exploded in a massive orgasm. Her hips bucked up from the bed, pressing her pussy against John's hand and she gripped his head to her nipple. She threw her head back and thrashed as her whole body shuttered, her legs quivering uncontrollably. Just as quickly as it started her orgasm subsided and she went limp. John as he always does, knew exactly how much pressure she could take on her pussy and cupped his open hand over it, stroking it ever so tenderly as he and I both. I don't think he realized I was there or he probably wouldn't have been strutting around half naked.He came in to the front room where me and Sarah were sitting, "Alright, faggot?" he joked. He always took the piss out of me but all in good fun. Sarah asked if I wanted coffee, which I did, so she walked into the kitchen to make some. While she was gone Mike tidied up the front room, I couldn't help but stare at his builders bum as he bent down to pick some things up of the floor.My gaze was.
