I overheard that the biology club was conducting an experiment and recruiting participants, so I decided to check it out—only to be instantly accepted. I caught the eye of a cute science-loving girl who fell head over heels for me, and before I knew it, I was being fucked over and over again. For the sake of "research," I was seduced repeatedly until my sperm ran dry, completely trapped with no way out. She acts like a mischievous little devil—rolling my cock around in her palm, thrusting her big ass out, and teasing her clit. Her sweet, sultry actions, like sucking on my dick with her mouth, completely wrap me around her finger. All to collect sperm as research material, I'm verbally abused and forcefully milked against my will.
"Hey, isn't your erection kind of weak today?" she presses me, leaving me unable to resist.
"What do you mean? You're not turned on by me?" she challenges, then aggressively teases, "What do you want me to do with this? Imagine it being touched—how does that feel?"
"I can't collect anything unless you shoot your load quickly..." she says, exposing herself shamelessly, yet her words are impossible to ignore.
"You like this kind of thing, don't you? You're getting excited, right? Don't you feel embarrassed at all?" she taunts, speaking as if she's thoroughly enjoying every moment of my torment.
"If it were me, I couldn't stand it. Just looking at such an ugly cock jerking off like this is so pathetic~! You should just spill all your gross, wasted sperm—lots and lots of it~!" she sneers with cruel delight, then adds, "But don't worry, I'll give you plenty in return," ramping up her seduction even further.
"Remember this—do you like it when I rub your clit? Can you feel it getting hard? This spot right here? This is my favorite." As she stimulates her clit, she scolds me for failing to cum.
"I'll help you go even deeper. I'll take care of it myself this time. Wow, look at how thick and abundant this is!" Her words send me over the edge, and when she asks, "Does it feel like there's still more coming?" I'm pushed to the brink once again.
"I'll make sure you feel good too. Consider this a special reward!" she purrs, intensifying her seduction.
"Slowly now... hey! Don't rush! Take it easy at first, feel it deeper! Inside my pussy! Yes, right there—ahhnn, I'm cumming! I'm going!" With complete control over me, she finally forces me to erupt.
