The fluorescent lights of the mandatory Human Intimacy Lab buzzed overhead as Professor Hale announced the day's assignment: gay fuck day. Every straight guy in the room shifted uncomfortably, myself included. I was the designated bottom, paired with Jake, a tall, broad-shouldered engineering major who looked as straight as they came. "This is for the grade, right?" I muttered to him as we claimed a padded mat in the corner. Jake smirked, his voice low and edged with sarcasm. "Yeah, twink. Top cums inside, bottom takes it. No backing out if we want that A."
We stripped down amid the awkward rustle of clothes from other pairs. My heart hammered; I was straight, damn it, but the syllabus demanded we perform. Jake's eyes raked over me. "You look nervous. Worried my cock's gonna ruin your straight-boy fantasy?" I shot back, "Only if your aim's as bad as your jokes. Let's just get this over with—grades first." The tension crackled as he stepped closer, his hand gripping my chin. "Full control means I decide how we play. Spit, fingers, whatever gets me off inside that ass."
Jake pushed me to my knees, his cock already half-hard. "Open up. Show me you're committed." I hesitated, then parted my lips, tongue flicking out in defiance. "Don't get cocky—literally. This is weird as hell, but I'm not failing." He chuckled, thrusting shallowly. "Weird? You're dripping already, horny little bottom. Feels good, doesn't it?" The blowjob built slowly, his fingers tangling in my hair, witty barbs flying: "Bet you never thought you'd be sucking straight cock for extra credit."
He pulled me up, spinning me around. Sweat beaded on our skin as he bent me over the mat. "Ass up. Time to prep that tight hole." Two fingers slid in, slick with spit, stretching me while he whispered, "Pussy's getting wet for me, huh?" I gasped, "Call it what you want—it's still weird, but make it count." His cock pressed against my entrance, hard and insistent. The first thrust stole my breath; he set a relentless pace, panting, "Fuck, you're gripping me. Gonna cum deep inside."
Bodies slick with sweat, we moved in rhythm. Jake's hand covered my mouth, fingers slipping between my lips as he pounded harder. "Take it all, straight boy. No cumming for you—just me filling you up." I moaned around his fingers, the sensation overwhelming, my own cock ignored but throbbing. "You're sweating like you love it," he taunted between thrusts. "Grades or not, this pussy's mine today."
The build intensified—his cock driving deep, ass clenching, wet sounds filling the air. Jake's breathing grew ragged, hips snapping. "Close—gonna cum inside you." With a final grunt, he buried himself, pulsing hot cum deep within. We collapsed, panting, the room echoing with similar finishes from other pairs.
As we caught our breath, Jake pulled out slowly, cum dripping down my thigh. "Not bad for round one. Class is just starting." That single line hung in the air, promising the next lessons would push every boundary further.
