This was a threesome, and I thought it was time to join them. I took off my shirt and lay next to Andy; she was on her side by this time, with one of ...er legs firmly between Charli's.I started by stroking her back, enjoying the play of muscles beneath the skin. She broke their kiss and turned to me with a smile. We kissed and Andy squealed into my mouth as Charli suckled her breasts.Charli kissed her way down Andy's body, and each new spot caused little tremors. I let my mouth roam and kissed. He collapsed onto me, sated, taking a moment to catch his breath. He still had some energy left though since he quickly got back to sucking whoever's cock I did not have in my mouth. We switched off a few times, and when we got to working on bald guy both at the same time, he shuddered, grabbed his rod and aimed his jet of cum all over both of our faces.That left bearded guy and me. Baldie slumped down in the nearest chair to keep watching the happenings, and Sissy straddled me like he wanted. No clothes between us… were clinging on to each other… I took the courage to slowly spread her legs with my own… she moaned into my ear n said ” Do it soooonnnn…. I can’t wait….. I beg u…. do it soon…” I obeyed… I guided my rock solid 6.5″ dick into her vagina…. She hugged me so tightly that I couldn’t move my body… I used to work out so I cud move just my groin …I took my penis back n thrust it forward…. She got so excited that she grabbed my ass… V fucked so hard… after a while she ordered. "I'll promise to act more adult like if you promise to live a little! Youneed to act more like Maddie. Adam will start asking questions if youkeep storming around the house like you're the boss. Lighten up! Be akid!"It pained me to admit that she was right. I was so concerned aboutkeeping the girls-turned-guys in check that I forgot about my role inthis whole situation. I'm the one that needs a babysitter now. I'm theone with the little brother that looks up to me. If I don't start actinglike.
