I moved behind Liz and started bathing her back while Cindy concentrated on her front. Eventually, Cindy helped Liz to kneel between us, so we could concentrate on the areas we had already used, and on an area that had not yet been properly explored. As my wife stroked Liz’s ripe and beautiful pussy, I bathed her ass, discarding the washcloth to allow my fingers to explore and probe her anus. Liz came again, luxurious and slow this time, when we each had fingers buried inside her.
We paused to sip our wine. “Are you having a good time, honey?” Cindy asked Liz.
“I never imagined this evening would end like this,” Liz said.
“End? Who says it’s ending? We’re just taking a break,” Cindy said, a wicked grin on her face. “Paul, look under that stack of towels. Is there something there that may be useful?”
I lifted the towels and found Cindy’s favorite cock-shaped dildo and a bottle of lube.
“Liz, I hope we haven’t gone too fast for you tonight,” Cindy said. “We’ve introduced you to some things that apparently were new to you. Having a woman go down on you. Having you lick another woman. Sharing a married man with his wife. Are you ready for more?”
“I guess so,” Liz answered. I could hear the uncertainty in her voice.
“Good,” Cindy said. “Paul, hand me my toy. Come here, Liz honey. I promise you we’ll be gentle.” Cindy sat on the low ledge inside the tub, and drew Liz toward her. They embraced, and starting kissing slowly as I watched.
As my wife kissed my student, she maneuvered Liz so that her firm little ass was exposed to me. She rubbed the toy over Liz’s breasts, then moved it down to tease her pussy. I could see the rubber cock rubbing back and forth over her lips, spreading them slightly, then moving away. Liz was gently humping against it.
Cindy looked at me and nodded. I opened the lube, coated my fingers with it, and stroked and probed Liz’s asshole. Then I coated my cock with the goo and pressed the head against her pucker. “Are you ready for me?” I asked.
“Just take it slow,” Liz breathed.
As I pushed my cock against her sphincter, Liz moaned, humping gently on Cindy’s dildo. Cindy pushed the toy an inch into Liz’s pussy, and at that moment, her asshole relaxed, allowing the head of my dick to enter her.
“Ooooh,” Liz moaned. “Cindy, help me.”
“What do you need, baby?” my wife asked, continuing to stimulate Liz’s lips and clit with the toy.
“I need that toy inside me,” Liz groaned.
“You want me and him in you at the same time? You want a DP?”
“Yes, please,” Liz whimpered.
By this time, I was halfway inside her virgin asshole. She was hot and tight, and squirming like mad. Her words seemed as though she liked it, but her body language said otherwise.
“Liz,” I said, “we don’t have to do this.”
“Yes, we do, dammit! Fuck me!”
Somehow, I managed to push the rest of my length into her until my groin was pressed tight to her buttocks. I stopped all my movement at that point to give Liz a chance to catch up, although I could feel my cock throbbing inside of her.
“Push that fucking toy all the way in, Cindy,” Liz groaned. “If I’m going to be filled, then fill me right!”
