Sarah was on her all fours on the grassy ground, her voluptuous body was an erotic view. Her boobs were big enough that I could see them from behind her back. Her well-endowed ass was so beautifully shaped, like an inverted heart.
I stroked her butt to experience its texture. It was a firm butt, but it was soft to the touch. I wanted to see her glutes bounce, so I gave them a little shake.
"Ahn~" Sarah moaned, she shook her hips in response to my play. "I want to feel you~"
I looked down and saw some droplets of liquid on the floor below Sarah's waist. My dear lover was already wet.
She didn't please herself, so that meant one thing.
"You are already like this," I said to her in a playful tone. "Is it because of the boob job or because we are doing it outdoors?"
"Don't be meanie~" she responded in an arousing voice. "Ah~"
I gave her a slap on her cheeks, that's why she shouted in pleasure. "If you don't respond, I will give you another slap."
"You are so mean— Ahn~" I slapped her on the other cheek. Now both sides of her rear were red. I wasn't doing that to harm her, I was just teasing her.
"Both…" she whispered.
"Eh? I can't hear you," I said to her, wanting her to expose herself.
"Both, I love to give pleasure to you, drinking your milk in nature," Sarah confessed her true feelings.
"Good girl." I praised her by caressing her red rear cheek. "Feeling better after telling the truth."
Sarah turned her head in my direction with her real cheeks puffed. Those were also red from a mix of pleasure and shame.
"You look pretty cute like this," I said to her, getting excited. I was ready to give her pleasure in return for her early treat, but I wanted to hear her begging for me.
I caressed her little flower the way she liked. I licked my fingers and then stroked her genitals, covering them with my saliva.
"Ahn… Aaaahn~" Sarah's moans echoed through the woods.
"What do you want me to do, Sarah?" I asked her, while stroking inside her slit. "Say it."
"Huh, I want you… I want you inside me, ahn~" she responded to my question between her shouts of pleasure. "Huh, I waited for so long. My body desires yours." She said while teasing me with her hips.
Sarah's plea deserved a reward, and I was holding it, giving a little slap above her rear with it. I stroked her coccyx with my meat, rubbing my member against her, preparing my girl for what she would receive pretty soon.
I was close to putting it inside Sarah's love cave, finally feeling a warm, moist sensation at my tip, but my body froze when I was about to penetrate her. My eyes focused on another cave, fixed on a little untainted hole right above her genitals. Her butthole.
At that moment, Freya's words came into my mind. 'I think she likes anal.' The goddess' words raised my curiosity about Sarah's preferences.
'I'm a Valkyrie Tamer. So I should use what I have to tame my underlings, right?' I thought inwardly, while my eyes were gazing at her tiny hole. "Sarah was a good girl, fulfilling her job with mastery. So, as her master, I should reward my girl properly."
I circled my finger around her anus, which made her startled, as if a shockwave crossed through her slim body.
"Rick! W-What are you doing?" she asked with a nervous voice thanks to the initial shock.
"Sarah, do you want me to fuck you right here, don't you?" I asked her, with my index finger still surrounding her.
"Eh?" Her head was in my direction, and it was clear to me that she was avoiding my eyes, ashamed to answer my question. Freya's guess was right. Looking at Sarah like this, I couldn't help myself and started to poke her asshole using my finger.
It was a more rigid entrance than her pussy. Of course, it wasn't accustomed to something going inside. But with some excitement, my finger was opening space through Sarah, making her rear gate start to feel like her womb cave.
"Aaah! Rick, don't do it… This place is not meant for that…" she said to me nervously. Different than before, she was suppressing her moans, but I could tell that she was liking it.
"You can tell me the truth. You want me to fill you inside here, don't you?" I asked with a teasing, sexy voice, tempting her to break free from her inhibitions.
"It's just… it's embarrassing to ask." She started to open up to me. "I don't want you to think that I'm a slut, but… Huh, I wondered about this last night." She confessed her dirty secret.
I pressed my finger inside her anus, piercing through her cavity.
"Ahn~" She moaned instantly, trying to cover her mouth with one of her hands, but it was too late. If she felt pleasure by it once, she could feel it again and again. Fingering her was becoming easier with time, and Sarah's hand got tired of trying to suppress her voice.
"Don't think so low of me. Do you think that I would judge you for that?" I asked her in a calm voice.
"I'm sorry~" She asked for my forgiveness, without hiding how much she was liking it. Finally, I took my finger out of her and put my dick at her entrance. The task for getting rid of my ailment was doggystyle, but whether it was anal or not wasn't specified.
"So I think I need to. You deserve a reward for all the work you've done. You are my woman, and I need to treat you from time to time." I said, caressing her cheek.
"Geez, I wanted to ask you last night, but it's so shameful." She said with a crying voice. Just one thing crossed my mind when I saw Sarah like this.
"Cute."
"What is cute about me wanting anal?" She asked, a bit irritated.
"All of it." I said with genuine love to her. "I will make your desire come true."
I pushed my member against her orifice. It was easier when I used my finger, but my thicker organ was feeling the resistance of her walls.
"Aaah! It is coming in!" Sarah cried. I was holding her by her slim waist, to support myself but also to help me go inside her.
"Sarah, I will get serious now." I warned her.
Sarah courageously nodded, with her moist eyes.
"Here… I… go!!" When I finished my phrase, I pushed my cock inside Sarah, while I pulled her waist toward me. My lance had successfully stepped into her back passage.
"Aaaaaah! Aaah… Aaaah." Sarah reacted as I pierced her rear.
"Are you ok, Sarah?" I asked her.
"I'm… fine… continue… please..." She asked me with a ragged voice.
I continued to strike her rectum, with each thrust her walls becoming softer, adapting to my spear.
"Ahn~" Sarah lost her shame and started moaning. "Don't stop…!"
"Do you like this, Sarah?" I asked while pulling her ass to get penetrated by me.
"Yes~" She responded, completely dominated by her instincts. "I like when you… go inside my butt. Ahn~"
I started to feel her body going in my direction. She was forcing my dick against her own cave. I didn't need to hold her waist anymore; she was doing all the work by herself.
"You are so naughty, Sarah." I said forcefully, giving another slap on her cheeks, making them bounce.
"Ahn~" She moaned happily, her body was sweaty after all the effort she had done by this point. She had a broad smile on her face. "It's so good! I love to be thrusted in my ass~"
If I could, I would continue. Eating her ass was a delightful experience, but it was coming to its end as I felt my penis trembling from the inside out.
"Sarah, it's coming! I… can't hold it!" I said, trying to avoid the inevitable.
"It's fine, my love. Let's cum together." Sarah said, completely aroused. "Just cum inside me! Fill my ass with your love!"
In one burst, I released my last spurt. "I'm cumming! I'm cumming! Aaaaaaaaah!" Sarah shouted as she reached orgasm. Her energetic self fading away after we came together, her arms and hands trembling after standing in a dog position for so long.
I removed my haste from inside her body, and she rested her arms, keeping her ass up, supported by her knees on the floor. My warm milk started to leak from her butthole, and little droplets of my seed sprinkled on the green grass.
"Aah, I could do this forever." Sarah said in wonder, still gasping from all our fun together. I was tired too, but finally I would be free from my suffering.
[ You cured the side effect of Ero Boost. ]
I could feel my body going back to normal as my uncontrollable sexual hunger was going away from me. I felt refreshed, as good as new.
[ You also made Sarah cum two times. Would you like to take two skills from her? ]
'Damn right I am!' I thought inwardly, and I was ready to examine the Valkyrie System once more. But from behind me, I sensed someone was watching me in the shadows.
