Wendy instructed me to position the black helmet at the entrance of her pussy and push it in gently. Still slick with her own honey lubricant, the head of the vibro slowly slid into her pussy, and sure enough the inches went in unopposed until at least ten inches were inside her. With her own hands firmly pinching her engorged nipples she asked me to do the honours and switch on the beast.
There was only two steps involved in this machine, off and jackhammer. I switched it on from the base and watched in awe as Wendy writhed in pleasure on the bed, arching her back and letting out a slow, loud, erotic, moan. She asked me in a breathless voice to pump the shaft in and out, and being the humble slave, I succumbed.
At first I only began drawing an inch or two of this massive shaft out if her cunt and then pushing it back in again, at a fairly slow rate. However, with her shouting encouragement i began to pull almost eight inches of the shaft out of her gaping hole before ramming it's full length back up again.
I kept having to switch arms to keep up. I realised pretty quickly that she wasn't going to come as quick as she had done in the sitting room. Eventually I heard those telltale yelps emanating from her mouth. I pushed the vibro in and out even more frantically before a foundation shaking yell fell from her lips. I gradually began to wind down the ferocity of the pumping before eventually leaving the entire length inside her and collapsing back on the bed myself, truly in awe of the experience I had just had.
Unbelievably Wendy had enough energy left to withdraw the shaft from her swollen pussy and turn her attention to me. She took my rapidly rising prick in her mouth again, working the helmet with her tongue as she rubbed up and down the shaft with both hands.
