I got to the gym early this morning before anyone else. Other than Lucy, the receptionist in a tight sports bra. I swear her tits must be bigger than basket balls. I was alone to lift at my leisure, but my cock just kept getting harder and harder. I was sporting quite the tent when I decided to do something about my erection. I went back to the locker room and toke my short off. That’s when I got the best idea ever. I shoved my shorts in my bag and walked out onto the gym floor, bottomless. Due to the layout, Lucy would not be able to see me unless she left her desk. I started pumping out some curls in front of a mirror, the veins on my 10” cock thick and throbbing. Realizing I was going to drip some precum, I opened my bag and got out a condom, wrapping it around my rock hard member before resuming my workout. 
I wanted to thrust, I wanted to thrust my hips at every rep. I put down my dumbells and went to the squat rack. With every squat I could hear the bloated condom *plap plap plap* against the ground. My pre was swelling it to the size of a softball. I closed my eyes as the pleasure washed over me. I was getting there without touching myself. The thought of Lucy’s big fat tits, me naked with only a shirt over my muscular chest, my big fat cock as hard as ever about to burst from the stimulation of working out alone. My eyes still closed I grunted a bit, trying to resist the urge to reach my hand down and get myself the rest of the way there, it took almost 15 more squats, slow methodical grunting before I went over the edge. I gritted my teeth as the strongest orgasm I’d ever felt washed over me. My sperm shooting into the condom on my shaft with force and getting tighter and tighter. With my eyes still closed I could see nothing but stars, even as the condom popped because of how much spunk I’d pumped into it I gritted my teeth and grunted out another 7 shots of sperm. I didn’t count, but I must have shot over two dozen ropes of thick baby batter.
Reracking the bar, I opened my eyes to see Lucy kneeling in front of me. The exploded condom’s contents all over her tits and from my perspective, every inch of her was covered in sperm. I froze in panic, my cock throbbing at the image of her unnatural fat tits covered in my own sperm. Then she opened her mouth to me, and I hit orgasm again. I was caught off guard and my first shot blasted against her chin, but the second hit its mark and landed forcefully in her mouth. After my previous orgasm I was only able to give her 20 shots, but they felt amazing. After shooting what looked like a liter of semen I finally started to flag. Turning around, I got in my bag and pulled out my shorts to put them on. She stood up with very shaky legs, not sure how many orgasms she had just watching me work out. I left as she went into the showers. Looking forward to coming in early tomorrow.
