Try something new: her ass

Lisa had said, "I want to see you make that sexy woman over there come so hard that she'll let you do anything you want to her. I want to hear her beg you for more." She had just begged for more. Did that mean she'd do anything I wanted? I guessed that it was time to test that theory. It was time to fuck her ass.

I had a girlfriend in college, Tilda, who was a wildcat in bed, wanting every hole filled every time we fucked. She was the only woman whom I had fucked up the ass, since I met Lisa when we were seniors. Lisa never wanted it in college, and I didn't ask after a couple 'no's. This was the time to try it out.

Lisa purred as I pulled out of her, my cock soaked with our sex juices. I moved my hands back to her ass and spread her cheeks again. I poked at her rosebud with my slippery mushroom head.

Lisa gasped. Then she moaned, her body shuddering. I pushed at her back door, and she moaned louder. This was good progress.

"Oh, Steve! Is that what you want? You want to fuck my ass? Oh, please, Steve! Take it! Break my last cherry!"

I pushed a little harder, just leaning in to let it pop in on its own.

"Oh. Oh, my! Oh, shit! Oh! Oh, Steve!" she said, the last sentence a rising shriek as my tip slipped inside her butt. I just stayed where I was, letting her freshly broken ass-cherry relax from my penetration. Lisa was ramrod straight and her sphincter squeezed me hard. She was breathing in pants.

"Relax, Lisa. You're doing great," I said, trying to calm her a little. I ran my hands up her body, grabbing her tits while staying put in her ass. "Take a deep breath and let it out slowly." She took a halting breath, held it a few seconds, and then she let it go. I could feel her ass loosen a little. "Again." She took another breath, and, as she let it out, I rolled her nipples in my thumb and finger. Her moan was loud, and her pucker loosened again. This time I pushed inside her ass, keeping up the pinching of her nipples. I just a few strokes, Lisa was no longer squeezing my cock with a **** grip, and I was halfway inside her backdoor.

"O, my God, Steve! My butt is on fire! It hurts so good! Our friends look like they are enjoying themselves too."

I looked up in the mirror and saw my wife's face for the first time since I entered her ass. It was a mixed of pleasure and a little fear. Your smiling face hovered over her shoulder, a look of deep satisfaction in your eyes. Your eyes lock on each other. Each of your thrusts makes her eyes get bigger and her mouth open wider. After just a few strokes, her moans come with every slow in and out of her asshole. After another minute of slow ass-fucking, Lisa pushed back into my cock as I lunged forward. Her ass took me almost as easily as her pussy did, so I sped up.

"Oh, Steve! I've never felt anything like this. Unh! It's like regular fucking, only darker and nastier. Mmmm!" Lisa was having a hard time keeping focused. "Are you gonna fill my ass? God! Are you gonna cum in my ass? Unh! Please cum in my ass. Mmmm! I wanna feel your hot cum in both ends."

Now that Lisa was helping me fuck her ass, definitely wanting more, I went faster. All that natural lube was making this easy. Her pleading to fill her ass brought my balls online, tingling with the desire to unload inside my wife's virgin rectum. I wanted her to meet me in my orgasm, so I slipped a hand down from one breast and buried it in her bush. I rubbed her clit, while I really pummeled her ass. Her voice rose in pitch and volume, and in the next minute, she broke into a raucous climax, shrieking my name over and over, as her body shook like San Francisco in an earthquake. My body also joined her in release, erupting inside her ass like Krakatoa. I managed to open my eyes enough to see us in the mirror. Lisa was screaming like a banshee and tossing her head back and forth like a soccer fan shouting, "Goal!".

I was slumped over her body, having very quickly fucked her front and back. I huffed and puffed, trying to replace needed oxygen. Lisa still whimpered and occasionally squeezed me with her pucker.

"Oh, Steve! Why did I stop you from taking my bottom before? I was afraid, but you made it easy today," she said as she took huge shuddering breaths, trying to recover.

"Oh, baby. I just never pushed you to do it. I'm just glad we figured it out," I said to reassure her.

"I think that's even more intimate than regular fucking. Will you promise me something? Will you promise me that I'm the only one you'll take by the backdoor? And I'll promise that only you can take my ass. Okay?" Her voice was hopeful and happy.

"I promise that your ass will be the only ass that I fuck, and I accept your promise that your ass is mine and mine alone," I said confidently. Then I turned her face toward mine and kissed her deeply, still embedded inside her butt. She clenched me one more time, then I extracted myself from her.

"I was right -- having your fire in both ends is incredible," Lisa said. "I can close my eyes and recreate both times in detail. Please keep taking my backside. I'll never stop you again."

"You have a deal, lover. And if I find something else I want to try with you, I'll ask you and not just assume you don't want to," I said. "Do you want a shower now? I'll take one after you."

"Oh, you go first. I want to stay here and just luxuriate in what we just did. Besides, you should get that cock cleaned off before you stick it in me again." She giggled, and her smile reminded me of why I fell in love with her in the first place.

I got up and headed to the bathroom.
