"I didn't even realise I was doing it." she smirked. Sarah began to remove her hand but Jack stopped her. She continued stroking as she watched Jack s...ide his hand into his shorts and begin to play with himself.Both continued to stroke themselves as they focused on the voyeuristic heaven. The woman was panting as the man sat up and began to thrust into her. She wrapped her legs around him and started to fuck back at him. Sweat began to drip from their bodies as their energetic screwing. Ann smiled, then said it was Wills turn to make her feel good. He wasnt sure what to do since he had never been this close to any girl. Luckily, Ann understood his lack of the female anatomy and guided his hand down to her still-virgin vagina. She took his index finger and pointed it on her clit. She was very familiar with her own body and knew what she liked, though no boy had ever touched her. Will felt more of his warm cum sticking to his hand as it slid down between her legs. Ann rolled. She took two wires from the machine. Both had small metal clamps. She handed one to me and pointed at Christina's pussy. With Christina still sucking my dick, I attached the clamp to Vicky's clit. She moved between Christina's legs and attached the other to her clit. I reached over to the machine and turned the big dial. The effect was instant. Vicky clamped her legs shut and bent at the waist. Eyes closed tight. Christina screamed around my prick. Her eyes flashed open and blinked several. I was to wear a short pink dress, pink panties, hold up stockings and a long blonde wig.All dressed we poured a glass of wine and waited for Dave and Maria to arrive, at seven exactly the door bell rang. I went to greet our friends only to find only Dave had arrived, apparently Maria was feeling unwell but insisted Dave should still come. Jaq confided in me that she and Maria had hatched this plan to get Dave to be able to get used to his role on his own.Dave sat having a glass of wine with us,.
