Inspired, Sort Of!

My mom's bisexual, I've known that forever, although I thought she'd not been with anyone since the one-night-stand that led to me. I was proven wrong.

I came home at lunch from college as I felt a bit unwell, only to hear a lot of thumping and moaning. Confused and delirious, I headed upstairs, and saw mom's door ajar. I decided to peer inside to see what film she was watching-she was naked, with a forty-something brunette!

As you can imagine, I was shocked and aroused. My cock was hard in a flash! I ran to my room and dropped my backpack and coat, and pulled off my hoody. I took off my shoes and socks, and t-shirt and jeans, and walked back to the doorway. I was in just my boxers, which I slid to my ankles. I pulled off while they went at it, cumming about nine times between themselves. I shot my load up mom's door, and all I remember is feeling really relaxed, sleepy, tired, falling aslee-

Mom was leaning over me in a camisole when I came to. Her friend was under the duvet further up the bed. I was naked. They were worried-I'd apparently fainted while watching them. They weren't too concerned about that though. In fact, they offered to put on a show.

An hour later, I was lying in bed with a sore but finally soft penis. Mom was asleep. Her friend was at her own home.

Oh what a day!
