Last week when I got home I needed to ask something to my dad so I went to his room cause I thought he was home. When I open the door I saw my Step Mom Joanna wearing a neon yellow bikini on the bed. I wasnt expecting to see her like that and she wasnt too pleased to see me walk in there like that. She explained that she dressed like that for my dad who was supposed to be here already but he wasnt and he wasnt picking up his phone either. She sounded a bit aggravated from that as well but her tone changed quickly when she saw the way I was looking at her and offer to give me a show. One thing leading to another she grabbed my dick feeling how hard I was and offer to help...
