Scarlet Curds
Scarlet Curds are made when an uncircumcised male and a menstruating female have sex and the male does not wash his foreskin for several days, allowing the semen and blood to curdle underneath the foreskin. The Scarlet curds resemble curdled milk with a slight reddish colour.
We had sex all weekend while she was on her period, Two days later she ate the scarlet curds off my dick.
