Paul mentioned he was building up an appetite and I offered to go make some sandwiches. I left them to it and went into the kitchen.I vaguely heard th... door bell go but presumed someone else had got it or ignored it. Then I heard another female voice which I could only presume was their daughter Amy.After about 10 minutes this young lady who must have been about 24 walked into the kitchen stark bollock naked." Hello, you must be Stuart, I am Amy, Paul's older sister and thought I would come say. Martin even tried to touch her body several times but couldn’t get much. Now the ball was in Martins court. Martin told Sabiha that he just want to have sex with her to keep secrecy. And he grabbed Sabiha’s arm and took her in the corner.Martin took her hand and placed it on his cock over the pant. Sabiha was hesitant but couldn’t resist. She had no idea what is going to happen next. Martin pulled out his pant in one go and here was the shock for Sabiha as his cock was huge about 10″ inches. I held my hand there then ran my hand down her leg and over her knee and looked up at her to see how she would respond. She said nothing and lit a cigarette. I continued to stroke her leg and pulled her tights away from her skin. “They feel nice, but also very tight” I said, “Don’t they make your feet and toes feel cramped?” “Not at all” she said and with that kicked her shoe off and started wriggling and spreading her toes. My nostrils were hit with the sweaty but so delicious odour of. I cupped my breasts, testing the sensation of the soft, smooth skin and how it contrasted with my puckered nipples, especially the hard, tight buds. My breasts were still damp, but warm again, and my nipples still stood erect, standing proudly to attention. I pulled them, twisting them slightly, and felt the inevitable tug deep in my groin.Reclining slightly, I ran my hands down, circling the soft skin of my tummy and hips in a gentle massage until I dipped my right hand further, to the wet.
