That day, she had a headache and she took a leave from her work. I didn’t know about that. As a routine, I went to her home as soon as her son left ...or school. I was surprised to see her in her night suit.When I asked her about it, she said she was having a headache and so she took leave. I was happy hearing that as it would be the perfect time for me.So I offered her a head massage. At first, she refused but after insisting she was ready for it. The head massage was just a reason. In fact, I. With my left hand I was holding her from behind & with my right I was pressing, teasing & walloping her left breast up & down. I started mouth kissing her while appreciating her fulsome breast in my hands.I turned around & lifted her up & I sat down on the edge of the bed & made my sister to sit on my lap. She was feeling the heat of my erected penis inside my trouser on her panty covered ass. I slowly started to give thrusting from below & kissed her chest hard. I moved my right hand inside. She did mention she had a date after I helped her with her router. I followed her towards the tights section and that's when my draw dropped and my heart started beating faster. She picked up some some Autograph 15 denier shine hold ups. I was extremely excited this stage and asked her if she wore those to work. She said she just wore tights to work but hold ups on special occasions and started blushing so we changed the conversation. Anyhow, she paid for the stockings, we both left the store. “Nice to meet you, I’ve heard a few things about you as well.”“We have ways of doing things around here, and one of the big things is that we don’t stare at them up there from down here. You’re new so I’m sure you’ll get a pass for now, but its best if you let them have their fun up there and you just hang out here and get to know the guys. Not a lot of people know what you’re going through, but we’ve all been there before.”I wanted to tell Mikey thanks but no thanks, I wasn’t one of them and I.
