We left all the windows open to remove any last traces of the smell of sexual activity, and Vee sprayed lavender air freshener around the half landing...The house having been pronounced sufficiently tidy, and a last minute check by Sian having found a stray pair of (very definitely used) panties pushed down behind the sofa cushions, we set off for our dose of fresh air.We headed north along Miskin Street and Corbett Road, and entered Bute Park, strolling along the path to cross the River Taff on. I still felt only skin.She giggled into the kiss and bit at my bottom lip playfully as I realized how little she was actually wearing. Her hands had slid round to my shoulder-blades, and I felt her nails draw down my back. I gave her ass a hard squeeze - gods, how perfect it felt in my hand - and was rewarded with a a full-body shiver as she remembered just who belonged to whom. Her hips wriggled inadvertently against the front of my pants, and we both realized that I was sporting an erection. As I got closer to her body I firmly grabbed and squeezed her left ass cheek."Great ass aunt Kate" I said."Behave now. You will get to explore every part of my body in the shower" she said and with that my dick stood again at full attention. As we got into the bathroom Aunt Kate started the shower so the water could warm up. She got into the shower then turned to me, "You the one that made me dirty, you should get in here and clean up your mess."As I got in the shower I watched as the water. I don’t feel used.”She was quiet for a moment, “The drink wasn’t an accident. I did that so I could meet you.”I laughed softly, “Well, that’s a new one for me. But again, so what? I accepted your apology and very much enjoyed the next day at the museums. And I was happy to take you to dinner and spend time with you.”“But I didn’t do anything for you,” she sighed.“Sure you did! You gave me great tours of the museums and kept me company. I thought we were becoming friends.”“But I didn’t...” she.
