Saturday.
I awoke early in the morning at 6.00. I was a bit confused, forgetting where I was. Then it all came back to me. With it came another raging hard-on. And the guilt and shame. I was disgusted with myself. How could I have lain there and played with my cock over my own grandmother. Was there something wrong with me?
I decided, as it was early, I would go to work. Leaving Gloria a note, I left. It was only half day on Saturday. Sometimes not even that long. It was just a case of finishing up the last weeks work and getting ready for the next one.
All morning I thought about last night. Trying to sort out how I felt about things. But I kept coming back to the vision of her. I'd seen so many things last night that had turned me on, I couldn't think about anything else. From the time she'd opened the door, to the time I'd fallen asleep was one long ride of sexual tension. She'd definitely left me with biggest blue balls I'd ever had.
I arrived home around 12.30pm and as I pulled into the driveway, grandma's Merc was parked just inside the garage. Leaving mine besides hers I walked around the back to put my work boots in the shed at the far side of the pool, ready for Monday morning. As I shut the door to the shed I noticed grandma had done some washing. I didn't think any more of it until I saw my gym top on the line. I suddenly reddened, knowing that she couldn't fail to notice that it was full of cum stains.
This situation was getting more out of hand by the hour. How was I supposed to face her now. I'd already been stupid enough to let her know that I'd watched her masturbate, by closing my door last night, and now, because I hadn't thought to put my dirty vest top away, grandma had found it and washed it for me. I was getting more embarrassed by the minute.
I couldn't stand in the garden as I was, looking stupid. I knew I had to face her soon. So l walked back along the path, scanning the rear windows as I walked. I didn't see anyone looking and entered the back door. Nobody in the kitchen. I felt relieved. I don't know why. I couldn't expect to avoid grandma for long. I went to the fridge for a beer and as I opened the door I saw it. On a piece of A4 was a note in broad red letters, ' COME & JOIN ME FOR GYM & SAUNA'. What was I going to do now? I couldn't see anyway out of this. She might of seen me arrive home, so I couldn't just drive off. Getting my beer I thought that Gloria would be just as embarrassed as me, if not more so. Seeing no way out I made my way to my room for a shower and change.
I entered the gym in another vest top and shorts. I looked over to Gloria. she was sat on a bench rubbing her face and neck with a towel. She was wearing a white terry robe. She smiled when she saw me.
"Hello Bobby. How was work?'
"Hi. it's always easy on Saturdays. How was your night out?" I asked as I kissed her hello on the cheek.
"Very nice darling. Thank you for asking. The girls were very frisky last night after meeting you. They think it's shameful that I should be here all by my lonesome with a hunk like you. I think they were both hinting about coming round more often and chaperoning us."
All I could do was smile at that. We made more small talk while I stretched and got warmed up. Looking around I noticed how well equipped the room was. Not as well as what I was used to. But enough to keep what I'd already built. It would certainly do.
I stood, and gazed around, trying to decide what I was going to do first. I was a bit conscious of Gloria watching me. I'm not used to that. She must of felt something as she quickly got to her feet and removed her robe.
I had to look away quickly. All she was wearing was a white halter-neck vest top and cut-offs. On her feet were white ankle socks and pumps. She looked awesome. Everything from last night came crashing back. I watched out the corner of my eye as she walked over to a mat in front of a large wall mirror and started bending and twisting. I was pretty sure that grandma couldn't see me watching. I kept her in my peripheral vision. Even so, I could see enough to give me another erection. How was I supposed to hide this in what I was wearing? What was I going to do when we went for a sauna? Going about my workout, I sometimes felt her watching me, but when I looked over to her she wasn't. I was sure she was though. After an hour I felt I'd had enough. Grandma was still on the mat, doing simple leg raises and such like. I went for my towel and made my way over to her. With my big towel hanging down in front of me I stood beside her and told her I was finished and was going to skip the sauna.
"Ahh, I was looking forward to that." she said. "it's always so lonely in there and I get so bored that I don't stay in half as long as I should. But if you don't fancy it, then I wont try and make you"
I started to feel a little guilty. I really wanted one but because of my predicament and obvious arousal, I was letting grandma down. Petty I know, but it seemed to mean a lot to her. I decided that if I went for a cold shower it would cool my ardour down, then I could go in with her.
"Tell you what, you go on in and I'll have a quick shower and join you shortly."
"Oh, that's lovely Bobby. You don't need to shower though. It's not a requirement." She said as she pulled her halter-top off. To reveal a strapless bikini top underneath. My cock instantly went gaga. They just weren't the tits of a 61 year old grandma. Or as I imagined them to be. I expected them to be veiny And at least soft and wrinkly. But they weren't. I tried to study her as she changed. even her face had few lines. Full lips and even white teeth. I wondered if they were her own. I also noticed for the first time how tanned she was. As far as I was aware, Gloria hadn't been away and there was no mention by her of a solarium in the house. However she'd got it, it suited her.
