My husband and I had just gotten into bed and were having a little pillow talk before going to sleep and the bedside lamp was still on. My husband, Ralph is twenty years older than I am and his son is twenty years young than me. Ralph's wife had a very unfortunate car accident when Riley was ten and that left Ralph all alone to raise his boy. I don't think he found me because he wanted more help, but he did find me and I liked him lots so when he proposed that we get together, I didn't find it hard to say yes in the slightest and I really liked Riley so it was all good.
That had been ten years of a great relationship and the sexual activity Ralph and I had was not the same frequent and excited occurrence any longer, but it was still good for about once a week and I think I was getting prepared for that weekly activity that night.
Ralph pulled me next to him and gave me quite a nice kiss and when I felt his tongue coming into my mouth with some force, I knew I had been right about the possibility of our activity. He reached over to pull down the straps of my nightgown so he could begin to feel my naked tits. The nipples reacted as they always did for his touch as they began to stiffen and elongate. Ralph loved that and always enjoyed getting his lips around each nipple and sucking them even higher. He continued that for a bit and I reached down to pull his pajama bottoms down to get at the dick that I knew would probably need some extra fondling to get it fully erect. I was quite happy to do that as he was always so attentive to my needs and had been for some time. He actually apologized for not being able to sexually satisfy me more often. I always told him my sexual needs were probably not as great as his, so I was just fine.
Ralph's hand had just pulled the bottom of my nightgown up in order to access my pussy when our bedroom door came open and Riley walked into the room. He was as naked as he could be and had quite an erection as he came in. He also had his eyes closed and wasn't saying a word, but was slowly walking towards our bed. I just looked at Ralph with a quizzical, 'what the fuck' look and he just shook his head and whispered, "I think he might be sleepwalking. He did that when he was much younger... and we just let him go... our doctor suggested it wasn't a good idea to try to wake him when he is doing that. He doesn't seem to hear much of anything.. let's just see what happens."
"See what happens? Ralph, Riley is in our bedroom without any clothes on and a stiff cock... we shouldn't wake him? What if he tried to get in our bed... oh, for Pete's sake he is trying to get in and he's on my side."
"Just scoot over, Honey, and let him in.. maybe he'll wake up soon or maybe he'll just get back into his bed."
So I did scoot over and sure enough Riley pulled up the sheets and got in right beside me. Now, if he had just gone on sleeping and not doing anything, it would have been fine, but that isn't what happened.
I was now sandwiched between the father and the son and I had my tits and pussy uncovered as we hadn't put our nightclothes back in place and now Riley had turned on his side and was facing me. He put his hand on my breast and started playing with the nipples as his father had...
"Ralph," I urgently whispered, "can you see what he is doing?"
"Yes, sorry, Honey, I can. He seems to like playing with your boobies.... A lot. I think it is hot."
"Hot? Ralph, this is your son doing this to his step-mother.... "
"Yes, but look at your nipples... they seem to like it as well.
