I was looking down on her rippling back and cute, round butt. I continued to slowly stroke my cock, knowing I was going to have to shoot this load bef...re going to bed. Suddenly I realized that her butt was rocking. She was still masturbating.Her ass muscles clenched and unclenched while the hand between her legs worked it's sensual magic. The towel had fallen off her head and she was pressing her face into the pillow. She raised her ass further into the air and I could see that both her hands. Her lips so soft and warm i instantly began to become aroused. My dick and balls tingled and were ready. We parted our kiss and i lifted Marys top and revealed her titties as she was not wearing a Brassiere. I pulled the top off and all she had left on was a pair of jean shorts. As i put my hand on her tit i felt Bills on the other one so we both massaged a tit and we both began to suck and kiss them from each side. Soon Mary was breathing heavy and saying nothing only sighing. I knew. Hopefully whoever or whatever inside was kind enough to at least let her stay the night and hopefully it wasn't infested with monsters that wanted to eat her or rape her. With a little hesitation, she knocked on the big wooden door with a knocker that had engravings of arcane symbols and the center was an engraved image of a potion with four elements surrounding it, fire, earth, air, and water.As soon as she knocked she felt a strange pull on her and immediately noticed there was magic pressure. " Mum looked very surprised, but Amy didn't, so Ireplied, "Why thanks Sophie, but you shouldn't." She blushed and quietlyanswered, "But I should! Although you can refuse it if I offend you."Now I was intrigued and slowly said, "What do you mean Sophie?" She tooka deep breath and the words came out in a torrent, it was like she hadto get them out. "Nicky, I would like to offer my body, so Brett and youcan have children, Brett can donate sperm and I can be inseminated, thenI'll sign the children.
