I hope my brother never learns about this!
Last summer my brother and his wife came to spend some days with us as part of their vacation. I always thought my sister-in-law was a hottie. She has strawberry blonde hair, perky boobs, and a nice figure, and her personality is wonderful.
We were going to have a party on a Saturday evening with a bunch of friends at our house. We had to get food and drink and a bunch of stuff for the party, so my wife volunteered to go to the store. My brother said he would go with her. That, of course, left me and ... I will call her Jenny ... alone in the house together. Not a big deal at all.
I took a quick shower then piddled around in our bedroom. I was deciding what to wear standing at the chest of drawers naked. For a flash of a moment I thought how sexy it was being in the house alone with Jenny, as I was completely naked. It was arousing. I started getting hard, so I decided I would just give myself a quick handjob to relieve myself. I laid on my bed and closed my eyes as I fantasized about Jenny, right down the hall going about her business with no idea what I was doing.
'Oh, Damn, sorry!' I heard Jenny say as she had opened the door to ask me something. She quickly backed out and closed the door. 'Oh crap' I'm thinking. Suddenly my dick shrank and I got dressed. I didn't finish. I was worried about what to say to her and especially how she was going to react.
I walked into the living room where she was sitting watching TV and I started apologizing. She told me it was nothing and to forget about it. Then letting her personality show she smiled and said 'nice dick, Jim!' I laughed and she laughed. I apologized again and told her I was just very horny. She asked me if I finished and I told her I didn't, that I immediately shrank when she caught me. We were both laughing about the situation. 'Too bad you didn't finish, Jim.'
'Well, I'll finish another time,' I joked.
'There's no time better than right now,' she replied ... but you'd have to finish soon before Deena and Bob get back.' I said 'are you serious?' She told me she was and added 'I'd like to watch.'
ZOOM! My dick went straight up. 'Come on,' I said as I got up and started walking back to the bedroom with her right behind me. 'You startled me when I walked in on you,' she said, 'but I want to see your dick again.' I took my pants off and she sat on the edge of the bed. I stood right in front of her and let her look closely at my raging hard dick. I was so hard! I started slowly jacking off as she watched me.
I told her I would love to see her tits as I jacked so she pulled her t-shirt up above her breasts. I was happy she wasn't wearing a bra. Her breasts looked wonderful hanging there in front of me. 'You'd better hurry and cum before they get back home,' she said. I gave myself some diligent strokes and told her I was cumming. She leaned out and held her breasts out for me and I creamed all over them. 'Ummm, yeah, cum baby ...' she said as I was squirting.
'That was damn HOT,' she said as she wiped the cum off her breasts with tissues. Then she gave me a wonderful sexy kiss. I pulled my pants back on and we went to the living room and had 15 minutes of fun sexy conversation before my wife and brother got back home. What a fun time! We never did that again though.
