...well....... Don't you think that its a little bit, I dont know, inappropriate to be masturbating in the kitchen.......in front of your step son?" I...asked nervously. "Oh sweetie, I just can't help myself. With your father being gone and you being here, its just that...... I haven't been fucked in several months. If it makes you uncomfortable, I'll stop.", she replied, opening her legs wider, giving me a better view of her cleanly waxed slit. I was fighting the urge to walk over and give her a. I stop and go back over to Karma and tell her to keep sucking him until he cums in her mouth and swallow it. Karma said she didn’t want him to cum in her mouth. So I put my hands on the back of her head and made her keep her pace until he came in her mouth. I told her to show me his cum and she did. Then I told her to go ahead and swallow it. She did and then said “OMG I can’t believe how good that tasted. The one and only time I tasted cum it made me puke.” I asked her how she felt. She said. Mike was curious about being gay and I explained terminology like bottom and top; I also talked about how my partner and I had threesomes, and described some of the things we'd gotten up to. He seemed shocked but interested.Mike's wife was visiting her family who lived some distance away so wouldn't be home for a few days. We went to his local for a few pints. Whilst there he seemed quite nervous and a couple of hours in he made his big revelation. Nervously he told me how he'd messed around. One I would come to know as pure lust. I took the sheet and pulled it completely off the bed exposing all of her, even her poor crippled, deformed feet. She had never let me do that before. Reaching for the hem of her nighty I pulled it up and off her. For the first time we were both completely naked.Sitting on the edge of the bed I leaned over and started kissing her. Gentle at first put with growing urgency and passion. As our tongues jousted with each other I was squeezing both of her.
