My suddenly-appearing stepmother has big breasts, and she wears light clothing at home, so I don't know where to look since I'm not used to being around women! My stepmother also gets too close to me and takes care of me, trying to get me to recognize her as her "mother," so I get hard every day! One day, I see my stepmother taking a nap and I can't help but touch her breasts, and she seems to be feeling it... so I get carried away and insert it! It feels so good that I end up cumming inside her, and she has an explosive orgasm with spasms! Then my stepmother gets up and asks me to do more!
