START-199 A couple who run a mobile flower shop are trying to get pregnant, and after letting strange men cuckold their wife, they aim for the ultimate 10-piston instant creampie. Hikari Aozora

A young couple runs a mobile flower shop and is having trouble with sex due to the husband's erectile dysfunction. The husband has been trying to conceive but has been unable to ejaculate inside her vagina, so his cuckold fetish blossoms and he asks someone on social media to cuckold his wife "so he can have a baby." After having sex with someone else, the husband embraces his wife with his hard cock for the first time in a while and immediately cums inside her. From then on, they start having sex and cumming inside her repeatedly.
