Please read previous Twins stories first. Thanks!
I got home from working the fence line with uncle just in time for dinner. We ate and talked about our day. Before aunt and uncle retired to their room for the night. I went to our bathroom and started the shower running and removed my clothes. I was standing under the water when the shower curtain opened and sissy stepped into the shower with me. It shocked me at first since we quit showering together when she began developing her breast. I caught myself staring at her firm and beautiful breast now. “I thought you might want company after your long day with uncle ” “I..uh..yeah sure.” Sissy moved towards me and rubbed her breast across my chest as she moved under the spray. Standing behind her now, I was looking at her beautiful ass as the water ran over her. I could feel my cock beginning to stir although I was trying not to think about it. Sissy turned to me, smiled and looked down at my half hard cock. “Brother, I watched you and aunt last night. I was amazed at how large your cock has grown since we were little.” She reached down and took my cock into her hand. She began to stroke it while kneeling down to take it into her mouth. She slowly sucked my cock until it grew to full hardness in her mouth. She stood and put my hand on her pussy. She moaned as I ran my fingers over her slit. I could feel her clit harden as I rubbed it. “I need you brother ” she tuned and leaned against the wall. Her legs spread, I inserted my cock into sissies tight pussy for the first time. I fucked her while reaching around to grab her breast. She orgasmed quckly , her pussy squeezing my cock as she moaned. I continued to fuck her until she came two more times. Feeling my need to cum, I pulled out and shot ropes of cum onto her ass.
This was the first time with sissy. We enjoyed each other many times over the next few years until she married and moved away.
