"So, dear aunt, I hope you will let him do it to us both. I can do to you what you have just done to me, because before we had him and Harry, aunt and I used to amuse ourselves in that way. Aunt is immense in that particular, she could put it a little way into me, and gave me great pleasure, and she said that I sucked it better than either her late husband or any of half-a-dozen schoolfellows who used to amuse each other; so, dear aunt, you must let me do it to you while Charlie is in me, and then you will do it to me while he is in you. Only fancy how nice it will be."
