I placed my right hand on the top of her head."Do you want me to blow you?" Edith inquired matter of factly."Entirely up to you, Mrs. Travers." Edith ..... please!" Entirely up to you ... Edith," I said to placate her.She pursed her lips and placed a quick kiss on the head of my cock. I remained motionless, but kept my hand on her head."Can I ... Can I suck it?" Please..." I said after a pause.She licked her lips and then opened her mouth and took my cockhead into her mouth, swirled her dainty. She straddled my legs and leaned down to let her tits slide up and down me from crotch to chest. She leaned down for a playful kiss then started sliding up and down me again, getting her hands and feet into the act too."Feels like getting a lapdance all over, doesn't it?" Even better than that," I managed to answer."Are you ready to fuck? I can't stand waiting much longer." I'm ready, babe."She moved her legs a little bit wider and reached down to guide my cock into her. It slid in smoothly. I knew it had to be my dumb sister, she must haveforgotten her key. So I got up and walked to the door and opened it, andin my best girl voice I said "it's about time you got her, I was soworried." However to my surprise it wasn't my sister. It was a boy. Hetold me he was sorry for being late and if I still wanted to go out forthe evening. This dumb guy thought I was my sister. I didn't know what todo. I didn't want to tell him I was a boy dressed like my sister. I wasreally freaked out. Just. " said Amy with a shaky voice, eyes closed and frowning. I was busily setting up connectors and conduits that would allow us to share. "Hold on you two, this looks like it's going to work."Suddenly both girls gasped in unison. "Wow!" We all felt the connection come together, A solid mental 'clunk' as all three sets of personality joined. I lost any feeling of a particular body image and instead, found myself conjoined in such wonderful cosiness with Amy and Valerie. We didn't move our bodies.
