I saw that my aunty and sister were removing their clothes in front of each other. First time I watched both of them naked. And this time my dick was ...getting out of control. It was getting hard.And here goes the real view; I saw that my aunt and sister are having a HOMOSEX with each other. My sister was biting the nipples of my aunt and my aunt was putting her finger into the vagina of my sis. This continued for almost 15 min. Then they both sat on the bed and were rubbing their body with each. Zack was also getting hotter but hadn’t gotten far enough before Ms. Four arched again and cried out. Zack refused to slack his pace this time, he let himself go, stroking hard and long, polishing his solid cock in her slippery cunt. He panted higher and at his peak, he was lifted again in Ms. Four’s pelvic saddle as she arched her back and cried out her loudest yet. Zack poured forth his coital offering and sang his own ecstatic symphony. He nearly passed out from the intensity but was able to. You said that you may cum any second. Usually when a male cums, they lose their interest in sex until they gain a hard on again. I am going to condition you so that even when you have cum, you are still willing and available and turned on enough to satisfy your betters. You will cum into this wine glass. You will wait 3 minutes until the effects of the orgasm have worn off. Then you will drink your own cum. Do you understand what I want you to do?”“Yes Daddy, I understand and I submit to it. What’s your name?’ ‘I’m Beth, and I’ll do my best to make you happy, sir.’ ‘Well, I hope you’ll do a very good job! You’re a cutie and I certainly wouldn’t mind having you come here every week. Right now, I have to get a move on. I’ll be back in a few hours and I’ll see how good you’ve done.’ I picked up my briefcase and keys at the door, punched in the code to arm the burglar alarm, opened the door and rushed out, closing the door behind me. To be extra safe, I locked the door before hurrying.
