HUNTB-681-Uncensored-Leaked — My sister-in-law, who is trying to conceive, came to me for my sperm in place of her infertile husband! One internal ejaculation wasn't enough, and she wouldn't let me pull out, continuing her relentless insemination with thrusts until I was completely drained...

When I visited my brother and sister-in-law's house after a long time, my sister-in-law suddenly begged me to "give me some sperm!" Apparently, my brother works until late at night or early in the morning, so their sex life has been neglected. My sister-in-law, who is getting desperate because she can't have a c**, turned her attention to me, thinking that her brother's sperm would be good! Though I was bewildered, I was satisfied with the unexpected raw sex, but my sister-in-law said, "One round isn't enough!" and held me down as I tried to escape, continuing to impregnate me with her piston-like thrusts until I ran out of sperm! "I can't produce any more sperm! Please stop!"
