We giggled like teenagers at the reactions of the other patrons and managed to remain un-shocked until right at the very end a figure that we had pres...med to be a statue in a tableau moved towards us. Both of us screamed at the unexpected movement. The figure laughed a little and spoke to himself, 'Gets them every time.' We emerged energised from the place, and still holding hands. A barker standing at a nearby bus stop announced the imminent departure of an open-topped sightseeing bus tour."Oh. I pushed into her, swirling my finger around as my thumb continued their ministrations and I switched back to the other breast. I pushed my arm underneath her, lifting her back slightly and pulling my mouth away from her nipple and onto her pretty neck. She groaned, her fingers digging into my shoulder. Her moans increased in frequency and she gripped a handful of my hair as she bucked and squirmed her way through an orgasm. Wetness pooled onto my fingers as her vagina tightened. I slowed down. Fuck me! Oh, please fuck me! Fuck me!" She fell forward, her breast pressed against the counter, as her hands reached back to grasp his thrusting hips. Her fingers dug deep into his flesh and she released a guttural howl like I had never heard from her before. I couldn't believe this was my wife, my conservative, sometimes prudish wife, begging this man to fuck her... rutting like an animal in heat. In sheer astonishment, I stopped stroking myself and just watched as the man's frantic pace. He held the suction cups so they just barely touched my skin and I was horrified as my body involuntarily leaned forward. The suction locked the tubes to me and I felt it starting. My nipple, then half an inch of the skin around it was sucked in. Then a little more, a little more, a little more. The same thing on the other side.Still without a word, the two men walked out of the room. The movie was still playing. I watched Yuki's face as the machine milked her, felt what the machine was doing.
