I am 50+, wife 47, my dick is too small for her, and she can rarely cum. Most cums with oral and on top. Giving her sexy scenarios like fucking in public makes her cum easier, she is attracted to younger athletic men, but doesn't confess to that. I am fantasizing about seeing her being fucked by another man, but am afraid she will leave me. Any advice on how to get started? She is very conservative, mom. Traditional, religious. Great athletic body. Very horny.
