I heard the noise again, it was coming from the attic. I found the door to the attic unlocked so I headed up to Laura’s room to see what was happeni...g.What I found made me question some of my instructions to Laura. Clearly I needed to amend some of them.Brenda was tied up in an intricate series of ropes and knots. She was hanging suspended from one of the rafters. Jim, the other trainer had his arms stretched above him to a hook in the ceiling and was blindfolded in front of Brenda. Each time. The deeper he went the louder her moaning became. Jill's body bucked and arched against the bittersweet assault. "That's it, fuck my little slut. She loves it, don't you babe?" Matt said as he sat stroking his own cock."I want to ride you." Jill said as she shook her head in agreement to Matt's question.Jay pulled out and lay on the bed, grabbing her to straddle him. Jill began to slide his hard wet cock into her hungry pussy. When she was down on him as far as she could go, she lay against his. She handed me the bottle and said, "Now you do me." I squirted some lube into her pretty ass crack, and massaged her rosebud. Raising her ass into the air, she offered up her rear passage. I placed the head of my cock against her tight little rear hole and pushed until the head was inside. Slowly I fed her more, and she stopped me saying, "Wait, let me get used to you." After a minute, she pushed back against me and I worked more and more of my 7-inches up her butt. Soon I was all the way. I estimate that his erection was at least 7 inches long, perhaps longer, and about 1 1/2 or 2 inches thick. The glans were distinct and almost seemed to be separate from the thickly veined pole on which it sat. The ridge that separated the glands from the base of his cock was intriguing to me. The thick vein running down the under side was prominently exposed as his erection strained upward toward the ceiling. There were several slightly smaller veins that were visible as they twisted around.
