I accidentally got a boner
I am 18 years old. I went to my friend's to help him move some stuff out of his garage. His mom was the one who originally called me to help her move some boxes from her house. I went over to Jack's house and then I helped him move a few boxes and then his mom called me inside to move some boxes from the basement. So I went down there, and moved a bunch of boxes. It all went wrong when his mom came down there and started helping me out. I was just an innocent young guy who decided to wear shorts to help out his friend's mom (not a good idea for a young man to wear shorts around attractive women).
To be honest, his mom isn't even that hot. She's like 40 years old with a decent body because she's a swim instructor. She is a very nice woman, me and her talk and I personally don't have any "feelings" for her. I felt a little funny feeling around my dick and I knew what was coming. She then bent over to pick up a box and then her shirt lifted and I saw her boobs. I didn't mean to but it just happened. She then looked up and saw my boner but didn't say anything but it was very embarrassing for me and awkward for her. I helped her lift all the boxes and stayed away from my friend because I didn't want him to think that I did something inappropriate to his mom. His mom saw the boner quite a few times and she smiled. The worst part was when she bend over right in front of my boner like 8 times or something ( I wanted to hit her in the butt just joking). The worst part was when she bent over only once and then gave me lecture after how " I shouldn't let my body keep me away from interacting with women." Overall I think she's a great lady and I don't have feelings for her but IS THIS NORMAL?
