"Stop squirming." I said to him, looking down at his sweat covered forehead and red bitten lips. My little bro squirmed in his seat, the clothes dad had bought for him this morning already way too small.
“Open wide bro, gotta fuck that pretty little mouth at least ten times before I’m spent.” He laid me back on the end of my bed, head tilted back to face him. I gasped for air, he panted with pleasurable exhaustion, but I didn’t see his dick deflate, or balls even look close to empty. His moans escalated, eventually he grabbed the back of my head and I felt his huge cock pump load after creamy load down my throat- pulling off only at the end to spray the last few globs of jizz onto my face. “Fuuuuck bro! Gonna have to get that app, make you a real musclebitch! Gonna fucking breed that ass!”
Voice even deeper, stubble covering his square jaw, fuck my little brother was a stud. Then he started to fuck my face, thick musky pubes wafting the scent of testosterone and pure man into my pores, tongue useless at anything but massaging his fat pole, heavy balls smacking against my chin as the last of his changes set in. “Open wide bro, I need to cum and your throat looks fucking good!” He was the same size as me, but the aggression, the dominant attitude, a cocky smirk as he shoved me to my knees and lines up the fat python with my lips. It would have all been fine if I had tested it out first though- I made my kid brother go through 8 years of puberty without emptying his nuts, the huge, heavy ballsack was swollen to the size of a grapefruit with all the pent up seed.
I downloaded one of The Company’s apps, a bio-enhancement application that allows the user to change the people around them with ease and anonymity. I guess that’s what I get for making my little brother go through puberty, probably without blowing a load. He was so rough with my throat, fucking it like just another hot, wet hole.
