Two weeks after breaking up with her boyfriend, a slight loneliness mixed with a horny mood made me want to visit Mariko. She had a somewhat lonely look in her eyes, and I felt she was trying to draw my attention. To comfort those feelings, I suggested a job where she'd jerk me off and give her honest feedback. At first, it was my cock that got hard, but only for a moment—we quickly got started. Mariko immediately began jerking me off and started licking my cock. She's the type who gives careful, thorough pleasure, someone who genuinely enjoys making her partner feel good. When she took off my pants, I noticed she neatly folded them. As a thank-you, I went down on Mariko's tits... and couldn't help but notice a firm, pebbly spot right in the center. She seemed to be getting turned on, and when I slid my fingers lower, I found her already wet and slick. Smiling sweetly, she kept sucking my cock. Then she whispered, "I'm feeling so naughty now... ♪"—her seductive way of asking for more was totally unfair. Of course, I was completely turned on too! After she took off her own underwear, her small pussy greeted me, her bright red, glistening clit on full display. I stroked her clit and fingered her inside, and soon Mariko was moaning wildly—things were heating up fast. Mariko's always had a strong sex drive, masturbating about four times a week. Now, her pale, beautiful breasts jiggled as she rode me in the cowgirl position, lost in ecstasy from her first real sex in a while, grinding her hips and squeezing my cock tightly. In the end, she tasted the cum I shot on her stomach, faithfully giving her feedback just like our original promise. Mariko left satisfied, having thoroughly enjoyed her first cock in a long time!
