Sue attached the cuffs to the rope and then pulled on a second rope to shorten it, stretching Julia just to the point where her heels barely touched t...e floor. Sue stepped back to inspect her work, then she leaned forward to again kiss Julia. She gently touched the end of her crop to Julia’s exposed pussy, and stroked her lightly. Julia’s facial expression changed immediately to a look of extreme pleasure. Sue stopped stroking. After giving Julia a light swat on her backside, she quickly left. He moaned as she smacked his ass again and again, her hand alternating between running over his cheeks and smacking them hard, occasionally sneaking down to graze his hard shaft or pull on his balls. "Well, well, well, it seems you are liking this quite a bit my little slut." She smiled as her hands wrapped around his hot, throbbing cock, stroking and squeezing him as she pumped slowly. "Give me some of that sweet precum, I need some lube" She giggled as she pumped his dick harder,. For a few years they had a normal life, but now they wanted to explore his bisexual side. I said it was the same case with me. He wmentioned that he was quite pleased to see that I was so cute looking as most of the guys they met seemed to be extremely old guys. I said he didn’t look bad either. I noticed he had his hand on the bench and was inching it towards me. Finally he got the courage and put on my thigh, just below my dick. I was wearing a tattered jeans and t-shirt. I could feel his. My heart began to pound out of my chest, and I was really shaking. Could I really go through with this? I thought to myself. I was wearing nothing but the towel from my shower, and was having serious second thoughts, when I heard a light tapping on the door."Crap", I muttered to myself.Shaking, I went towards the door. I could feel my dick hardening under the towel, despite the nerves and second thoughts. I looked through the peep hole and hesitated. I really wanted to do this, but I was scared.
