Ok so I (34m) had the house to myself for what was supposed to be a few hours my MIL was swinging by after she got off work around 4. with it only being about 1 and me being horny but my cock locked in a chastity for loctober I stripped down to just my cage put some nipple clamps on and grabbed my 10in vibrating dildo and stuck it to the glass door to the backyard, picked out a porn and started going to town. I could feel the big O cummin and letting out moans, my legs where shaking. as a heard the front door open (straight line of sight) and I drop to the floor dildo just swing on the door and all I hear is "oh are you naked". So that was fun, but I bet she texts next time she's on her way over earlier then planned.
