Let's get them both naked.

I realised Melinda was still wearing her uniform and that wouldn't do, especially since having her turn up crushed and smelling of sex would probably engender questions that could lead back to me.

"Stop" I said, and they did, looking at me.

"Melinda," I continued "get up and stand at the foot of the bed. Alicia continue to lie on the bed, but your hands behind you head and keep them there."

The girls reluctantly disentangled themselves from each other and did as they were told.

"Melinda" I said "I'm going to removed your clothes and, as I do, I want you to look at Alicia and tell her exactly what you want to do to her. Alicia listen to what Melinda is saying and look at her body as I reveal it to you."

I pulled Melinda's blazer off her shoulders and off her arms

"I want to kiss you all over" she began "Kiss your mouth, kiss your breasts..."

I reached up and undid her tie.

"... suck each nipple into my mouth... maybe bite them gently ... not too hard ... I want you to enjoy it..."

Alicia was biting her lip as I undid the buttons of Melinda's shirt.

"Mmm ... move my mouth slowly down your belly... slowly down ... down toward your ... beautiful ... wet ... pussy."

Melinda seemed to be enjoying stretching out her description and the effect it was having on Alicia who seem to be vividly picturing everything Melinda was saying.

"I want to kiss you there ... running my tongue along you labia... up until I touch your sensitive clit ..."

I removed Melinda's shirt revealing her white cotton bra.

"I want to hear your cry out as I lick you"

Alicia groaned and I reached around and undid Melinda's skirt allowing it to drop to the ground. Her white cotton panties were already showing signs of her excitement, and I made a mental note to have her leave them behind.

"I want to slide my fingers inside you so you can feel me deep within you and I can feel you orgasm."

I undid deftly undid Melinda's bra and then told her to take it off, which she did, leaning forward and almost coming face to pussy with Alicia before straightening up.

Both girls were (almost) naked now and listening to Melinda had been as exciting for me as it had been for Alicia. I could sit back, watch and let the girls enjoy themselves for a while before I joined them (being, as I am, a man of superhuman willpower and endurance) or I could join them now so that we would finish in good time for the ladies to be home before their absence became too suspicious.
