"Mmm, let's make my big brother feel better, mmm, let's cum and feel real good, come on, cum for me," she said softly as she stroked on and on.Well, I...sure wanted to and I knew I was close. What was happening was so incredible, my own sister, just the thought of it being her doing this put me over the top as I let out a groan and started cumming spurts up in the air as she pumped me up and down."UHH, UHH, UHH, uh, umm, mmm, mmm, oh, wow, oh, 'Licia, that was incredible," I moaned as she bent. ’ ‘Gonna be a bit lonely at night though,’ he hinted, edging in closer to her. ‘Mmm – here too… Maybe,’ Christi said and twitched her eyebrows. ‘Oh, so what’s that about then?’ ‘Did you notice we had an audience again this evening?’ He kissed her neck before replying, ‘Nope. Guess I was too busy trying to win at first, and too busy trying not to lose in the end.’ Christi stroked her fingertips over his hard member beneath the sheets as she spoke, ‘You were a little distracted in the armory too,. "I won't know what to do " I told him which made him laugh."Do you wank yourself off " he said and when I nodded he answered, "Well just do the same thing to me."I leaned across and wrapped my hand around his shaft and slowly started to wank him, I could feel the heat from his member and was amazed at just how hard he felt. Steve asked me if I wanted to take my own dick out but I shook my head."Why not I have got mine out don't be afraid " I began to blush as I told him I was ashamed of my cock. His teeth graze the soft skin beneath the hard line of my jaw, while his wicked slippery tail ventures ever further toward my opening. It brushes gently across my folds and I bite my lip to keep from crying out. The arrowed tip of his extra limb probes the area around my smouldering clit and finally, finally rubs against it.The climax is earth-shattering, launching my wound up body into a seizure of orgasmic spasms. A nova blast of heat lights up my entire being, spreading like ripples through.
