Sexually, I was nothing but gentle with Lillie. I was too afraid of hurting the frail girl that I couldn't bring myself to be rough with her. I was always slow and caring with her, taking care to not offend her. I always lead the way, doing my best to keep her at pace worth me. She seldom did anything too out of the ordinary, choosing to keep our sex as vanilla as possible. Of course, it got draining on me and I soon struggled to stay sexually interested in Lillie. Sure it was nice to cuddle and talk after sex, but only if the sex was interesting enough to have in the first place. Slow and gentle missionary grows old over time, especially when you've seen the grass on the other side of the fence once before.
That's when I began to notice Lusamine. I had always thought that she was pretty, but I soon took notice of how attractive she really was. Everything from her hair, to her face, to the way she walked and the clothes she wore, it was all just so attractive. Lusamine wasn't as plain as Lillie, and I certainly noticed that there was more to her than she let on. As a result, I wanted her, and I think she noticed. However, she didn't mind the attention and even began to pursue it from me. She began to dress certain ways around me, and act differently to get a reaction.
One time in particular, we were all in the television room watching a movie, when I noticed something happen. Lillie and I were on the couch and Lusamine was sitting in her chair when one of her breasts fell out of her night robe, a fact that I'm sure was on purpose. I couldn't help but get a long, healthy look at it. The nipple stared back at me, calling for me to touch it. As it hardened it took every bit of my strength to not reach out and grope it. Lusamine even gave me a look that said it was okay, but I couldn't bear to break my bond with Lillie. It was agonizing to know she was tempting me so.
Then, Lusamine did the unthinkable. One day, it was just me and her alone eating breakfast in the Aether Mansion. Just the two of us, Lillie had just set off for her morning shower and would be sometime before she finished. Sitting across from me, Lusamine fiddled with her robe. It loosened and began to part, ever so slightly. I began to grow hard at the thought of her naked breast and did my best to not look. I looked down at my feet, hoping to keep my mind at ease. "It's okay," she said, "you can look."
As I looked up I saw that she had fully parted her robe and now sat bare chested before me. The sight of just one of her breasts had me fully erect, but the sight of the whole set had me practically pierce through my pajamas. I stared for what felt like eternity, taking it all in. Then, she reached out and grabbed my hand. She guided it to a breast and smiled as I instinctively grabbed it. It was so soft, yet firm, the erect nipple massaging my palm. It took every fiber of my being to not play with her. I couldn't do this to Lillie.
Lusamine didn't stop there. She climbed under the table, crawling towards me. Before I could ask what she was doing, I felt her at my legs, tugging my pajamas down. "Don't." I protested half heartedly, but I couldn't bring myself to put up a fight. I knew how wrong this was, what the repercussions were for me if I was caught. Lusamine was Lillies mother, but I was just the boyfriend. I can always be replaced. However, sex with Lillie had grown so stale that I was losing control. I never even asked Lillie for oral sex, and here was Lusamine coming for me. I wanted this so badly it hurt, I wasn't going to stop her now that I was this close. Not when she had my pants down to my knees. Not when she put my cock in her mouth. And especially not when I came in her mouth.
I had my hands on her head as she gave me head, digging them in as I came. She made a point of looking up and showing me my cum in her mouth before she swallowed. She gave me a smile as my cock rested by her face. I was disgusted with myself. I could have stopped this but I couldn't. My heart raced faster than you would believe humanly possible. I had to get away from the seductress. I had to get to Lillie, the girl I actually loved.
I entered my shared room with Lillie as she was coming out of the shower. I knew I should tell her, but I didn't. I was overflowing with emotion as I approached her. Lillie was wearing a towel that was wrapped tightly around her still wet body. She barely said a word before I pulled her into me and kissed her. I had to prove to her I loved her. I had to prove to myself I still loved her. She didn't fight back but instead fell into me like the perfect puzzle piece. Not a single word was said as she dropped her towel. Instinct took over both of us, even her. However, we didn't just have sex; we fucked like animals. We both forgot about our inhibitions and did what we wanted to.
I pushed her against the wall and held her legs in my hand as I banged her against the wall. Lillie was finally enjoying sex more than she ever had, digging her nails into my back as she finally came. I stopped only to move us to the bed. There, I laid Lillie on her stomach and fucked her from behind. However, I had finally had enough of this. With a groan, I pulled out and came on Lillies back. Despite my recent romp with Lusamine, I was still able to land quite a load on her.
Of course, I couldn't lose my erection as Lillie began to grind her butt on my dick. She was still so horny, and I couldn't blame her. We had never had sex this wild, this good. Was it because my slip up with Lusamine opened up something inside me? I wasn't sure, but I knew I had to open up inside Lillie. I fucked her again, spanking her this time. She cried in joy as I did it, my cum pooling on her back and rolling down her sides onto the sheets. The sound of our hips slapping together while I slapped her cheeks echoed through the room. I came inside her, but not before she had her finish as well. We cuddled for hours after, kissing and feeling each other as the sweat and other things rolled off our bodies. We both agreed that was the best sex we'd ever had, and we'd have to do it more often.
The question for me, was where did that lust come from? Had my encounter with Lusamine unlocked the lust I had kept down, and if so, did she know this would happen? She had always been the perceptive type, maybe she saw I was more interested in her than Lillie and figured she would see what I would do. I confronted her the following morning over breakfast while Lillie was having another of her long showers. "Of course I figured you'd feel bad," she said matter of factly, her robe tightened this time, "but I knew you two weren't pleased. I figured I'd take a gamble and see what happened. I'm quite impressed with you."
"How so?" I asked, wondering what she meant.
"Besides physically," she gave me a wink, "you two were the happiest I've ever seen you. Obviously, you did what I was hoping you would do."
"You were trying to help our relationship by almost ruining it?" I couldn't tell if I was angry or if I was happy, it was another flurry of emotions that I wasn't sure how to control.
Lusamine sipped her coffee. "There was always the risk you two would break up. However, I noticed how you reacted to my teasing. I knew that if I didn't act while you still loved Lillie, things would have turned out much differently."
"You gambled on our relationship." I angrily shot at her.
"I love you both." She defended. "Now you two are the happiest you've ever been. It may not be the best method but by god it worked." I was silent for a moment, looking down at the table as I mulled over what she said. While it very will could have ruined my relationship with Lillie, it also greatly improved it as well. I still wasn't sure what to think. Lusamine reached over and held my hand in reassurance. "I'm always here if you need me." She said, slowly pulling the tie on her robe.
Was she really suggesting we do this again? "I can't handle this again." I said, pulling my hand back.
Lusamine laughed as stopped undoing her robe. Then she got serious again. "I guess I should clarify, if you love my daughter enough to give her what she wants when she wants it, then you do it. But if you need the fuel to the fire started, I'm always here with a lighter." She gave me a wink. "Of course, I'm always free to teach you or my daughter a few tricks if you want to."
