The beginnings of erections were starting on both boys and that made Sue happy. The longer she made them stand before her under her scrutiny, the more...aroused they were becoming. Sue was going to put both of those cocks to good use before the afternoon was over.Sue spent the next half-hour watching as they paraded up and down the living room. Giving them hints and suggestions on moving their hips, teaching them to walk with their weight balanced forward and how to take shorter more girlish. After the hour was up Mike left the room. I spent the next several hours trying to get tips but no one was really buying. I had several guys who would join the room,ask me to flash my ass/cock then leave. It was exhausting and I got bored.Finally, I had had enough and left the room for a few minutes. I knew where the toys were and grabbed a set of anal beads, two dildos, and a set of sounding tools. It took me a while to figure out the zoom function from the keyboard. I laid back and started. She looked up at me with her little puppy dog eyes and i just melted as i just nodded and she began to snake her hand below my waistline and grabbed my dick. I was speechless, i didnt kbow what to do with my little sister, naked next to me was playing with my hard dick.She just looked me in the eye whilst she told me to take my trousers off, i just complied not knowing what to say just doing what i was told by my younger sibling. she started playing with my dick, giving it the occasional lick. We have a room here i said do you want to join us. We got to our room and Marc sat down on the chair and Dave and I stood and hugged and we kissed for a while. Marc got up behind me and undid my blouse and removed it as Dave looked on. Marc unclasped my bra and let it fall and squeezed my tits and pulled on my erect nipples ready for Dave. Marc went back to sit down and I got on my knees as Dave undid his pants and let them fall. My eyes staring at his bulge ,I grabbed his boxers and pulled.
