Massages

Last year I go visit my mom and stepdad on the ranch to give my mom a 30 to 45 minute massage to help with these horrible knots she gets my stepdad is so caring that he gets neurotic when she's in pain because he can't help so usually he finds stuff outside the house to do. So me and her just chit chat while I work on her shoulders. I'm not sure why but for some reason since the first time I started doing this when I sit behind her I'll have my pants and zipper undone and my cock just laying out. It had never been to risky or anything it was just comfortable like that. Well we've always been open and talked freely to each other about everything going on with them and she knows what's going on with me. When I was out there before Thanksgiving last year she asked if I knew anything about ED meds or why it happens. I tell her what I know but I also ask if my stepdad is still interested in sex,. She said no but thought it was because the ED. I told her the many different things it could be but most of what is was is his age. But meds might help otherwise it's a psychological thing. I asked if he still did other sexual things she said no that they hadn't done anything since may of last year. So as of now that basically means no sex in a year.
Well anyways the last time I was out there giving her a massage I had my cock hanging out and like normal and I leaned back to stretch my back and my dick moved and hit her back and she turned to see what it was and noticed it so she shifted around and asked me why I had it out and I told he it's comfortable and she knew I'd sit there completely naked if I could, well she turns back around and I go back to massaging her she asked if I ever played with it behind her. Which I had before while I was letting a hot towel loosen her neck muscles and she was looking down I recorded a video of me playing with it for my girl. She asked when that was And I told her in December. She found it interesting, but wouldn't tell me why. I joked saying I keep it out for quick access to a happy ending if requested. She laughed and said it would be more a vaginal massage rather than a shoulder massage lol. Anyways I went out there yesterday to do the massage and when I got there I found out that if I wanted I could be fully naked because her husband was gone for the weekend. So I got in my usual spot and she sat in front of me and I got to work and doing our usual catching up and I was doing my normal thing of moving around her bra straps but yesterday she said fuck it and took it off made my life easier. To work but now I could look down and see her tits and got hard. I asked how she felt about being naked near me she says she's only half naked so she doesn't know about how being fully naked would feel. Asked how I felt told her I felt comfortable accept for uncontrollable erections. She stood up and undid her pants and pushed them and her panties off and looked at the right time to watch my cock get hard she laughed saying its not bad though. And sits back down I keep massaging I wound up doing it for an hour. Normally the last thing I do is stand in front of her out her head against my waistline and stretch everything towards me. But since I was naked didn't know if she wanted me to, turned out she wanted me to because her neck had been killing her so I put her where my waistline is she held onto my hips like normal except there was no barrier between my dick and her breathing so I felt my erection coming and warned her she laughed saying she's been watching it the whole time and then blew at it getting it harder I asked her why and she said boredom and to see something, and I ask what was she going to try ? She said give her a minute few moments later she licked it with her tongue and followed it up by putting her mouth on it. For about 2 minutes then stood up and ask about the vaginal massage. Yes we fucked yesterday like three or four time and a fantastic blowjob. Wish I could of recorded the blowjob.
