I turned my attention back to Tansy. She was still in the same place, waiting patiently, head down and arse invitingly in the air. I wiggled forward on my knees until the tip of my strap-on was between the cheeks of her arse. I reached down and moved it around, making her very aware of its presence. I felt around with my fingertips.
Mmm, she was so wet and ready and eager.
I found her entrance and guided the dildo there. I pushed forward very gently, and I felt it slip inside, and we were on our way.
For the next half hour, I fucked her with an almost infinite slowness. Poor Tansy, it must have been so infuriating that I teased her so much. Gradually my thrusts became easier as her pussy got wetter and wetter giving my dildo easier and easier access to her centre.
I reached under her and found her nipples. They were as hard as diamonds. I played with them, giving Tansy a random mix of gentle caresses and hard pinches. In the end I took pity on her and started to speed up. I felt her tense up and I could almost feel her cunt tightening on my dildo.
"Do you want to cum, Tansy?"
"Fuck, yes, Miss Laura!" she pleaded with despair in her voice.
"Then ask me properly," I ordered her.
"Please, Miss, please ... let me cum please Miss." She was almost sobbing.
"Cum for me, sweet Tansy."
And, as if released into freedom, she did exactly that. With cries and moans her body convulsed. The words that came out of her mouth were beyond my comprehension. I slowed, but didn't quite stop my strap-on's thrusts, but let her dictate the pace. As she slowed, so did I. Eventually we were both still, her arse still high and my dildo still inside her. Very gently I started to pull out. Before I finally came free, she collapsed sideways onto the bed. Moments later I did the same carefully not to fall on top of her but behind her. Reaching out I took her into my arms and spooned into her.
I don't remember much for a while so I think we both must have slept. When reality dawned, I was lying beside her, awkwardly tangled together, the tip of my dildo still inside her. As I moved to get more comfortable it slipped out and she woke and turned toward me.
"Oh fuck, Miss Laura, that was amazing. Thank you, thank you."
I suddenly had a bright idea. I unbuckled the strap-on harness and wriggled out of it. I held it up before Tansy's face.
"Would you like to try it on?" I asked her.
Her eyes grew wide, and she grinned broadly. She lifted her feet as I placed the harness on her. She knelt while I got it in the right position and fastened the buckles, making sure it was secure on her. It was strange to see this beautiful young black woman with a pink dildo pointing directly out in front of her. She reached for my pussy, but I stopped her.
"No, Tansy, not me." She looked disappointed and puzzled. "I love it, but I don't enjoy it being used on me. I just love using it on another. But wait, I have an idea ..."
I got up from the bed and walked over to where bitch still knelt patiently waiting by the door. I took hold of the chain that linked the two nipple clamps and pulled. She looked up at me with surprise and pain. Using the chain, I led her over to the bed and made her crawl up onto it. Realization of what I expected was beginning to dawn on Tansy and she made room.
"I thought bitch deserved a reward. I think she suffered a little on her visit earlier. Now, Tansy, take it slowly to start with. Let her build up. She is allowed to cum but only with your permission. I leave you in charge. I am going to sit outside on the veranda, but I'll look in every so often to check you're okay so don't worry. Call if you need me."
