I walk past your room as see you're still awake, so late. I come and sit on your bed to talk to you, my robe slipping open slightly to give you a glimpse of my tits. After a while I notice your cock is hard under the sheets, this has got to be part of the problem. I cant just leave you like this. It's ok, there's no need to be embarrased, I'm here to look after you. I take my robe off and encourage you to stroke for me, I get more and more turned in i this naughty situation, watching my step-son get so hard for me. I'm rubbing my pussy above your face as we both orgasm.
