SCPX-512 - Mother-in-law and son's large penis

I thought I was living peacefully with my daughter, but it's a pity that my stepson's penis is too large and we have no sex. I decided to take a look during a consultation, and the erect penis presented before my eyes was more robust than I imagined, and I was surprised and captivated... If this were to penetrate my vagina, it would constrict instantly, because my vagina has a reputation for being a vessel that accepts anything. [Mother-in-law's account]
