My 20 year old wife has no experience at all in sex, I fuck her and she settles for me, but lately it fantasizes me to see her with a big black cock, so I bought her 3 black dildos in different sizes, not so much used them, but she really loved them, and she Told me yes she will try them, I'm afraid if you try them then you will not feel me anymore or you will not want my cock anymore can it happen?
