You

You pull a chair over

"Sit down" you tell Rob and he does so.

You begin to remove your clothes while standing in front of him, blocking his view of Ashley and Tina. Despite you revealing your body to him Rob seems unhappy that he cannot watch the other girls. You can see his hand slowly creeping toward his member.

"No Rob, you must not touch your cock." You say to him and then, loud enough for the girls to hear. "In fact I forbid any of you to masturbate unless I give you permission. If you need sexual release for any reason you must come and tell me. If I am not around but one of you is then you must convince that person to help you out. If Ai, Bea or Sissy are here, of course, you will just need to order then to do so since they answer to you three whenever I am not around. Do you understand?"

"Yes Mistress" Ashley gasps.

"Mmm-Hmm" Tina says into Ashley's pussy making her squeal.

"Yes Mistress" says Rob moving his hand back to his side.

"Good" you say.

Once you are naked you turn around so you are facing the bed with the girls on it. You move back until you feel Rob's legs behind you. You then slowly lower yourself until you can feel his rod which you reach down and position at the opening of your already dripping cunt.

"Are you ready to fuck your first cunt?" you ask Rob.

"Yes Mistress," he says throatily.

You lower yourself onto Robs shaft allowing it to slowly penetrate you, filling you, contacting every nerve in a way that nothing ever has before. You can't help but groan with pleasure, a sound which Rob echoes behind your head.

"Now Rob, " You say, fighting the urge to just move up and down his pole until you both cum "the first lesson you must learn is self control. This is not just important when you are inside me, it is vital when you are with any woman. Most women are used to men who cum too soon, before the woman herself has, and then loosing interest. You must make sure you do neither. In order to help you learn how to control yourself I forbid you to reach orgasm, no matter what, until I do."

"Yes, Mistress" groans Rob in a voice which makes it clear this will be close to impossible. Taking pity on him you whisper a spell that you saw on the way home that will ensure that everyone in the room will be in perfect harmony sexually. Everyone will approach climax at the same rate as you and will orgasm at the same time.

"Now Rob" you say "Reach around and put your hand on my breast and the other on my pussy."

Rob does as he is told.

"Now put your finger down and see if you can find my clit."

While Rob is enthusiastic it takes little coaching from you to help him find what he is feeling for. The results, however, are worth it. He slowly and softly rubs your nub, gently driving you toward climax with a deftness that belies his lack of experience. It is not long before you feel yourself about to burst.

"T-Tina ... You ... You can cum now. So can you Rob." You say as you go over the edge yourself.

The room is filled with the groans and gasps of the four of you reaching simultaneous orgasm. You slump back on Robs chest and Tina slumps to the floor at the foot of your bed.

"Wow" you say "That was so amazing. You're all so wonderful."

Just then the doorbell rings.
