Yes, gladly...

I smile and pull her face to mine by tugging on her collar. Her eyes turn hopeful.

"Helen, I´m overjoyed you want me to be your Master. So, get ready for a great birthday evening. And many more evenings to come." I tell her and kiss her gagged mouth. Helen closes her eyes and just enjoys the gag kiss. But just before she start to enjoy it a bit too much I pinch her left nipple, making her whince.

I let her collar go and notice that while I was reading she´s cuffed her ankles together and her hands together in front of her. I grab her by the shoulders and pull her across my lap, giving me excellent access to her cute pert asscheeks. She gets what I want and wiggles her ass for me while I rub it. "You must really want this ****."
Helen nods eagerly, and then I bring your hand down on her ass, hard. She yelps and I feel her ass tense up. I then rub her ass for a bit before slapping it again. I then spend a few minutes on near constant spanking. At the end of it we're both sweating and my hands are sore. Her ass has taken on a cute pinkish/red tone and she´s got tears running down her cheeks.

I cup her face and rub away the tears with my thumbs, then I remove her ball gag. "How are you holding up so far?"
To my surprise she smiles. "I´m doing great Sir. But could you gag me if you´re not going to use my mouth, it kinda ruins the mood otherwise."
