Mom in her underwear

I was startled as I heard my bedroom door open and hit the wall. Without even looking over I knew mom wanted to continue the argument from earlier. I didn't.

"MOM! Could you knock at leas-" as I turned to look at mom in the doorway I was stunned. "Huh... WHA?!" I couldn't speak. I was in disbelief as mom sauntered into my room and stood in front of me with her hands on her hips. Gone were her clothes from before. All that mom had on was a matching dark grey lace bra and panty set with flower black lace trim. It was amazing that small bra could hold up mom's ample tear drop breasts. I swear I could almost see the nipples poking through, but I don't know if that was true or just want I wanted to believe. Looking at her skimpy panties I could almost see the shape of her slit it was so tight. Looking below on each of her long elegant legs were black garterless stockings. Gazing back up an mom's face I could see the determined look in her azure eyes. It was like she was staring daggers through me.

I felt my mouth go dry and blood rush to my prick as I gazed at the sight in front of me. "W-What? Why're you dressed like that...?"

Mom didn't break eye contact with me and said with all the seriousness in the world, "Matthew, I'm going to give you a proper lesson in sex."

What?!

Mom had to be fucking with me. This was all some sick joke about the Sex Ed grade and saying I would end up as some weird pervert some day. It felt like my room became a sauna being there in my long sleeve shirt and jeans in front of my practically nude MILF of a mother. I couldn't help my nervous laughter as I tried to talk to mom. "Haha... t-that's a pretty bad joke, Mom." Mom's demeanor did not change. "No matter how bad my grades in Health class are..."

"SILENCE!" Mom just cut me off. She wasn't hearing any of it. "Listen, Matthew." She moved her hands from her hips and down to her sides letting me take her all in. "This is for your own good. So don't worry about anything and let mommy handle it."

L-Let mommy handle it?

I don't know why, but when mom said mommy I could feel my cock twitch as it kept swelling.

Mom looks so hot in her underwear... WAIT! NO! This is seriously bad!

As I stood there gawking at mom I noticed her gaze go down from my face to my groin and then her eyes go wide.

"Oh?" Mom couldn't help but giggle. "I'm relieved, knowing that you're interested in women." The playful, sultry way mom said that didn't do anything to help alleviate my arousal.

Looking down I could see that my jeans provided a clear outline of my sizable stiffy. As I desperately tried to conceal myself in front of mom, she sashayed over to my bed and sat facing me, casually removing one of her heels and then the other. Even with both hands trying to cover my wood wasn't very effective.

"Alright, then... let's get started."
