Catherine stuck her tongue out, and I started playing with it, sucking on it gently.
She needed me to guide her through each step, but I was patient.
Once she got the hang of it, she'd be able to please me perfectly in the future.
I touched her tongue with mine, signaling her to bend it a bit. Then I curved my tongue around hers, wrapping it around the back of her tongue, and waited.
Catherine seemed to get what I was doing and followed along, wrapping her tongue around mine.
She had the basics down, so I led her into more advanced tongue-kissing. My tongue twisted around hers like a snake, lightly touching the tip as our tongues danced together.
After about ten minutes, my tongue started to get sore, so I sealed her lips and nibbled on her lip.
Catherine caught on quickly. She started sucking on my lip, just like I had done to hers, taking some of the saliva off.
This was a good chance to see how well she had learned.
I mimicked her initial moves, opening my lips to let her suck on them.
After a while, Catherine noticed I wasn't responding and lightly tapped my chest, signaling me to react.
I smiled at her. She still had her eyes closed, cheeks flushed, and the glass around the shower was misted up, creating a steamy atmosphere.
The mist clung to the glass door, making it look like a scene from an erotic video, with Catherine and I as the main protagonists.
When I still didn't respond, she let go of my lip, opened her eyes wide, and stared at me fiercely. But with her flushed face, she looked more adorable than intimidating.
"I taught you how to kiss for so long, now it's time for me to see how well you did," I said. Catherine's cheeks turned even redder.
"Come on, let me check, and then I'll charge you for the lesson."
"What? You want money?"
I sighed, "I don't care about your money."
"Then what do you want?"
I held Catherine a bit away from me, creating some space between us, and then looked her up and down.
"What do you think I want from you?"
Catherine followed my gaze and understood. She covered my eyes with one hand, then pounced on me, complaining, "Pervert!"
"You're my girlfriend, and it's normal for me to be into your body. Come on, kiss me. I need to see how well you learned."
"No. Your penis is too big. It hurts me. I don't want to do it again," Catherine said, lying on top of me, shaking her head.
"I have a new way that won't hurt you, trust me."
Catherine still shook her head, rejecting me.
"If you don't want me to check, I can just go ahead and penetrate you," I whispered softly in her ear.
The warm breath in her ear made her shiver. She lay on top of me, feeling like an electric current was running through her.
Especially her vagina, the wet and soft flesh pressed against my abs, contrasting sharply with my hard muscles. The clean and soft pubic hair above her vagina rubbed against my abs, feeling incredibly stimulating.
My cock beneath me felt the stimulation, rapidly growing, even larger than when I first got home.
I couldn't wait any longer to assess her kissing skills; I felt like my cock was about to explode.
I sat her on a shelf to the side and went to grab some shower gel.
Luckily, the shelf in her house was high and sturdy, capable of supporting her weight without any concern of damage, as it was securely embedded in the wall.
Catherine couldn't help but gasp, tightly gripping my arm to support herself.
"What's wrong?" To prevent her from falling, I took a few steps closer to her, then freed one hand to support her butt.
Catherine leaned on my arm, cuddling against me, and said coquettishly, "It's a little cold."
The way I held Catherine was like a parent holding a child with one hand, and she leaned her forehead against my temple.
"Then I'll just pretend you're sticking to me." I tightened my grip on her arm, her legs against my abdomen.
Her toes touched my cock, which was hot and very hard, and she quickly withdrew her feet.
I hadn't even had time to spread the shower gel in my hand when she tried to take her feet away. I quickly grabbed her two feet and placed them on my cock.
"Don't take it away, sweetheart. Just use your feet to rub; it feels very comfortable."
Catherine was a bit shy to put her feet up, wanting to take them away, but I held her feet and gently rubbed her toes against my cock.
Her toes were very tender, the toe pads were plump, and the nails were neatly trimmed.
I held her foot in my hand, rubbing her toes up and down against my cock, creating a bit of a wrinkle on my cock, then slowly releasing it.
I continued to do this for a few rounds, and my cock felt a tingling sensation all over, very pleasant. My whole body felt like it was filled with adrenaline, full of passion and desire.
Her tender foot was evenly coated with the shower gel in my palm, making the sole of her foot a bit slippery. I held her foot and rubbed it up and down against my cock.
The firm, hot touch stimulated the itchy flesh on the sole of her foot. Every time I rubbed her toes against my cock, she couldn't help but open and close them, accidentally pinching my pubic hair when her toes closed.
My pubic hair was stretched as her toes moved away, and the root of the hair protruded. If she kept pulling, the hair would be pulled out.
But there was some slippery shower gel on the pubic hair, so after a short pull, the hair would slip out from between Catherine's toes, and the skin around the hair instantly relaxed.
This alternating tight and loose feeling was quite pleasurable.
"Stop it... My foot is so itchy," Catherine said softly.
"But it feels so comfortable for me when you do this. I love it when you use your feet to help me masturbate, it feels so good."
While enjoying it, I lowered my head to kiss her nipple, nibbling on the soft flesh a bit, then licked around with the tip of my tongue.
Her snow-white breast instantly had a pink mark on it.
