Erica pulled at Alfred's cock harder as she felt him near his peak, his words only confirming her suspicions.  She rocked her hips against the void that Cass had left, and released one of her hands to fill the empty space.  The other found Cass' body and slid under her stomach to reach her sires' folds, deftly parting them to expose her bud and press in time to Alfred's thrusts.  Her fingers pushed into Cass's hole, and into herself, and Alfred pushed into her mouth.  The feeling of both of them touching her, her touching both of them made her moan again.  This was what she had wanted, what she had dreamed of when she'd went to see Alfred.  The rocky start didn't negate the current joy that filled her heart, and she was more and more convinced that the three of them, if they were able to work so well together like this, might actually be able to work together outside of the bedroom.  At any rate, it was amazing to have them both at once, and she wasn't going to let the chance pass.
