So today....
Went over to my FWB's place to chill. I was laying on the bed and my mom called me. I answered and then all of a sudden he pulled my underwear down and rammed his cock in me. I wasn't expecting that and I accidentally let out a little yell and started to moan. Mom asked me what I was doing and I lied and said I was at the gym and I'm moaning from being sore lol. I wanted to get off the phone but he said to stay on because it was turning him on. I tried to stay as quiet as I could but it was so hard, I had to move the phone away from me and muzzled it with a pillow. He came in me and let out a big moan. She asked what that noise was and I said a guy is really getting into his workout and she said she'll let me get back to my workout and said goodbye. She may or may not have realized what was going on idk. She's walked in on me before fully fucking so it's not as awkward lol
