While the family was out, I called a delivery health service—and to my shock, the woman who arrived was my son’s kindergarten teacher, Nishino! She shyly asked, “Should I call to switch?” but still spoke gently. I decided to talk with her first. I asked if it was really okay for her to be doing this while my wife was still in the house, and she laughed nervously, responding, “Is it really okay for me to be doing this kind of side job?” She said she’d just started this work, and I was her first customer. She mentioned the shop manager had given her oral training. Hearing that, I couldn’t help but imagine Nishino in a lewd situation—had she been forced to suck some guy’s cock during training, even though she didn’t like it? When she reminded me, “I should make the switch call soon,” I realized that changing would just send her to another man. Wanting to stop her from doing this work, I decided not to switch and instead tried to convince her to quit. Then, when I mentioned how much my son adored Teacher Nishino, she burst into tears and apologized deeply. She explained her younger brother had accumulated massive debt, and she couldn’t quit the job until it was paid off. Fully resolved to continue, she bowed deeply and said, “Please… be my first customer!” While she looked away, my cock had somehow become fully erect, and she stared at it, softly murmuring, “It’s so big…” as she gently stroked it. She used her tongue to lick every inch, giving an intense blowjob with loud, wet slurping sounds—deepthroating all the way to her throat in a passionate irrumation! She serviced my cock like she truly loved it. Turned on, I moved in for a kiss and groped her breasts, making her writhe and twitch uncontrollably. Her tits were enormous—uncontainable, explosive breasts! A staggering K-cup! When I fondled her beautiful nipples, she convulsed violently and climaxed. She seemed extremely sensitive. Touching her pussy through her panties, I could feel her juices soaking through. After removing her panties, I gave her a thorough cunnilingus, making her scream in ecstasy. One orgasm after another from skilled fingering. Then it was my turn—she used her massive tits for titfuck while giving blowjobs in alternation. We extended the time and moved to the bedroom for sex. Seeing my son’s desk and bed, she hesitated, remembering this was wrong. I relentlessly teased her pussy with a vibrator while sucking her tits, bringing her to repeated orgasms. Finally, I shoved my thick, hard cock into her soaked, slippery folds. With every thrust, I enjoyed her soft, jiggling body in every possible position. In the end, I filled her pussy with a massive creampie!
