New Medication

I live with my mother Cheryl 46 and recently she was given a new medication and it made her very sleepy at first. But after several days her body adjusted to the medication and she was no longer getting sleepy. But she started getting rather horny her words, at first she thought that it would also pass. But after a week it was still arousing her and she couldn't satisfy herself and so she came into my room totally naked after trying to masturbate herself to satisfaction and not succeeding. I was shocked at her being naked and was even more when she asked me to fuck her. We live a rural 5 acre block miles from town, with no close neighbors. She told me that I was her only hope to satisfy her. I'm Ken 23 only child and not much of a ladies man and with my cock going hard I agreed and fuck my mother Cheryl. She stayed all night with me and we fucked 3 times that night and more on the Sunday morning and night. The Monday she went and seen her doctor and he told her that it wouldn't last much longer. So she kept taking the medication and sleeping with me. By the following weekend her arousals started to ease and soon she was back to what she called normal. I was a little disappointed at her not being horny and thought no more sex. Cheryl decided that we could still have sex every now and then. But I would have to find a girlfriend. I sleep with her every night and get sex once and sometimes twice a week.
