I have asked her in morning how she is doing, and if the drug is helping. She said it is taking the edge off, and she was able to refrain from smoking but she feels she might need another cycle of the medication. That day she went to her doctor and told him something that resulted her in getting a new script which I saw her bringing home in the early evening.
That night I again walked past her room and there she is going to town on herself. But what is different this time is I lost all control. I am not one that usually masturbate or aroused by the thoughts of incest, but ever since seeing my mother in such a state or arousal a man can only take so much.
Standing there in my pajama pants and t-shirt with no underwear I drop my pants, and take off my t-shirt and climb onto her bed positioning myself right behind her. With her rubbing her clit I position my cock at her opening and slide right in. it is at that very moment mom awoke and said "Charlie?"
I didn't reply, instead I grabbed her hips and started pounding my mother from the rear. She responded by taking her hand away from her pussy and with both hands grabbing the sheets till her knuckles turned white, and her mouth remained open making sounds of sexual pleasure.
Being that I jerked off twice prior when she was at work I was able to last longer than usual. But eventually I reached close to the end and said out loud, "Oh god...I am going to cum." And right after I hear mom say, "Me too...."
After we both had our orgasms, I pulled out and climbed off the bed and grabbed my clothes and intended to leave. But I was stopped by hearing two words from her: "Thank You!"
Epilogue
I have personally taken this drug for this very reason. The dreams are so vivid when you wake up from them you say to yourself, "Oh nuts! It was just a dream." They feel so real when they happen. If it was safe for me to take the drug daily for the rest of my life I would.
