Hilary & Grace II: University Girls Watch The weekend after the two young women in the apartment upstairs had first watched me jerk off, I kept thinking about what had happened. Over and over and over again. There was no doubt in my mind about their excitement and their interest: they liked watching me play with my cock just as much as I liked them to watch. On Friday afternoon after I'd washed and put on clean clothing, I could still hear them chatting about what they'd seen, talking to each other in animated and enthusiastic voices, occasionally joking and laughing. Their voices weren't as loud and clear as they had been before but I did catch an occasional phrase from upstairs. They seemed to be working out when and how they would react, whenever they were looking at me; what they would do and would not do. I overheard Grace say "but not when there's only one of us here" and Hilary quickly agreed. I felt butterflies in my stomach, hearing them making their plans. It's usually the flasher who has to think carefully and figure out all the angles. These young women were deciding how, when, and what they would do -- to encourage me to jerk off for them! I felt a strange mix of anticipation, excitement and nervousness. Part of my nervousness was because of my girlfriend. We had a decent sex life but she knew nothing about my exhibitionist desires or how much I loved to stroke to a climax while women watched me. I'd hinted around the subject a few times and found her interest was zero. I didn't want to push her to do something she didn't like; but neither did I want to lie to her or tiptoe around her back. Another part of my nervousness was the risk of losing my job looking after the buildings. If either of the women upstairs told my boss what they had seen, I'd probably be fired instantly. However, this opportunity felt just too rare -- and too good -- to pass up. I reluctantly decided not to tell my girlfriend what I had done on Friday afternoon and then see how things progressed with the girls upstairs during the next week. Time went by very, very slowly that weekend. Finally it was Monday morning and my girlfriend headed off to work. As usual she'd showered before me. This morning I stayed in my bathrobe after getting up and had only a coffee with her before she left. I was too nervous and too excited to eat. About half an hour later, I heard Hilary and Grace moving around upstairs and talking as they usually did in the morning, sitting in their kitchen at the back of the house. I lit a cigarette, took a deep breath and walked very quietly into our living room at the front, wearing only my long bathrobe with nothing on beneath it. I carefully closed the drapes, laid down on the couch with my bathrobe wrapped around me, and I waited. It was less than five minutes before I heard a set of light footsteps enter the room directly above. One of the girls had walked into their living room, paused for a few moments, then quickly walked out. Immediately after, I heard Hilary calling out to Grace in an urgent, excited voice. Within seconds I heard the sound of their feet as both of them rushed in from their kitchen. There were two loud thumps as they dropped to their knees, then creaking from the floorboards as they laid down on the floor. Now I could clearly hear the sound of their voices as they talked to each other. They weren't speaking any louder than they had been before in the kitchen, but it was obvious their faces were now pressed right to their floor. And it was obvious they were both looking down. At me. The girls immediately began making comments to each other and giggling. The sound of their voices was mischievous and amused, excited; two young women about to see something they had both been looking forward to seeing again. I put out my cigarette in the ashtray, then slowly reached down with my right hand and began to lightly rub on my cock through the bathrobe. "He's doing it!" said Grace in a pleased tone, almost singing out the words. "He's doing it for us" replied Hilary with satisfaction. She was right. I was doing it, for them. I very much wanted to encourage them to keep talking. So whenever one of them spoke, whenever I could clearly make out the words they said, I pressed down harder on my cock through the bathrobe or rubbed around it. The more they talked and the louder they talked, the more I did. As their conversation continued, gradually I loosened the tie on the robe; then, bit by bit I began to spread it open, wider and wider on my chest. I lifted my left leg up and free of the robe. Then, I slipped my right hand under the bathrobe and began stroking my cock directly, tenting the fabric but not letting them see underneath. It was like doing a slow and sensual striptease lying down, with their voices in control of the pace. The more often they talked, the harder I got; and it seemed the harder I got, the more often they talked. Finally, after one especially-loud direct cry from Hilary ("Show us!!") I pulled my robe open wide and began slowly stroking my cock where they could see it. My left hand went down to circle my balls, my thumb and first finger wrapped around the base of my cock. I held it up, throbbing, as the fingertips and thumb of my right hand slowly slid up and down, from the base up to the tip and back down again. "That's it!" one of them called out happily, and their voices were now getting very excited and a bit wild. I could feel the heat in the way they spoke, I could feel their excitement. It felt really good to me, it felt wild and dirty and very, very hot: I knew two young women were looking right at me as I stroked my cock for them. Knowing they knew I was completely aware they were watching. It made me very hot to know they knew I was jerking off. For them. It wasn't long before I came, on some tissues I'd quickly pulled out of a bathrobe pocket. Again the girls became very quiet in the last minute before I came, obviously caught up in the sexual drama of watching a relative stranger spurt for them. I came hard, pumping and squirting again and again over the tissues I'd spread on my stomach. I wanted them to see... everything. They did. And they really liked seeing it. They wanted to see it again. Tuesday morning was more of the same. Once more I waited for my girlfriend to leave for work. This time, I also waited until I heard the girls up above go from their kitchen to their living room. I waited a few minutes before I walked in, trying to build their anticipation. It worked. As soon as I stepped into our living room, they began talking louder and thumping lightly on their floor, trying to get my attention. Without looking up, I laid down on the couch and started to rub my cock. Again, I let them set the pace of how soon I opened my bathrobe and how quickly I came, responding with my actions whenever they talked and giggled. Wednesday morning began just like Monday and Tuesday. I laid down on the couch, listening to their voices, started rubbing my cock through the bathrobe, finally opened it wide and begun stroking towards a climax. Suddenly I heard the sound of the electric buzzer from upstairs and I realized the girls had a visitor at the front door. One of the girls raced down the stairs and opened the front door. I heard Grace's voice say "Hi!" brightly and another young woman's voice reply cheerfully "Hi! I hope I'm not too early?" Grace laughed and said "No, you're just in time for breakfast!" in a coy and amused 'I've-got-a-secret' tone. Both of them were giggling as they hurried up the stairs. As soon as Grace and the visitor were upstairs, before they had even closed their apartment door, Hilary exclaimed "He heard you at the front door!" Within seconds I heard the sounds of Grace and the other young woman dropping to the floor. Then I listened to their eager and amused comments and laughter, while all three of them looked down at my naked body, while they watched me stroke my cock until I came for them. Three young women were watching me jerk off this morning. And now, I knew the two women living above had told their friends about the show I put on for them: Hilary and Grace had talked to their friends about me. Now, they had started inviting their girlfriends over, to watch me strip and stroke my cock -- and cum -- for all of them to see. And now, they knew I was willing to jerk off. While their girlfriends watched.
