Big Brother, My Private Area Seems Too Tight... Can You Use This Adult Toy to Stretch Me? My Boyfriend's Dick Is Too Big to Fit... After Helping My Sister Who Couldn't Have Sex Because Her Boyfriend's Cock Was Too Large, Things Got Weird... Rion Izumi

After returning home from a date with her boyfriend, the younger sister was depressed over her failure in bed. Seeing her determinedly trying to stretch herself, I noticed she had started masturbating daily. Unable to resist any longer, I made up an excuse that "it'll make it easier for your boyfriend's big cock," and began having daily practice sex with my sister. Gradually, she started enjoying the sibling intercourse under the pretense of practice, and before we knew it, we were deeply immersed in intense, full-fledged sex. *Note: This work features a solo selection from the previously released title "HUNTB665."
