Spying On My Step-Mom Pays Off

Story - My stepmom just caught me jerking off and, not to be dramatic, but I think this might be the end of everything. I've never been more embarrassed. "Did you see that?" I ask, praying she'll say no. Instead of judging me, she touches my dick, and I flinch. Don't get me wrong, she is a total milf, and I spy on her all the time when she is showering (nothing turns me on more than smelling her pussy in her delicate panties), but I never thought she would be interested. Would it be really messed up if something happens? She moves her bra, giving me another chance by offering me her big tits. That's it. I don't care how weird this is, that body is mine now, and it's about to get fucked like never before.
