My [18M] mom [38F] has been teaching me how to kiss and almost gave me a handjob

My mom has been teaching me how to kiss and I'm getting turned on like crazy. A few days ago something happened where she touched my penis for the first time.

I'm an 18 year old virgin, and my 36 year old mom has recently been teaching me how to kiss girls. It started because I briefly made out with a girl at my senior prom, but it didn't go very well, and I ended up leaving very embarassed with no further action. My mom felt bad for me and offered to teach me how to kiss, but that's all it is, it's nothing overtly sexual. Our lives are not one of the typical stepmom pornos where she wants to train her boy to last longer. Well, I guess I should say, that's all it was... until last week.

I will start by describing each of us. I am 18, half desi/half white, about 5'9", 160 lbs, and a huge nerd. I like math, programming, and certain non-mainstream sub-genres of hiphop. My mom is 38, 5'4", about 120 lbs, small tits, really nice ass, and extremely attractive (see pics). At home I usually wear basketball shorts and a t-shirt while my mom wears yoga pants/shorts and a tank top. Because it has been extremely hot this summer, that has sometimes changed into walking around in underwear. But it isn't like that all the time, it's a rare occurence - like I said, this is not a porno, this is my life. When my mom is in her underwear, it's pretty much always a lacy thong of some sort.

It started with just lip kisses, but quickly progressed into tongue kissing and making out. We also started sometimes cuddling on her bed while kissing, during which we are always in our underwear. Aside from the girl at prom, this is the furthest I've gone with a girl. I'll just get to what happened last week because I know that's the reason you're reading this.

I was sitting on the couch watching Netflix when she sat down next to me, put her hand on my shoulder and said, "Sit closer, let's cuddle right here." She gently pulled me to her so I was laying with my head between her breast and shoulder. She started telling me about how much I look like my dad, who left about 10 years ago. I don't have any siblings so it's been just the two of us for a long time and we have become very close. As we talked, she put her hand on my chest, and rubbed it gently with her fingertips. I felt my nipple get firm under her fingernail and she worked her hand down my stomach. Slowly, as we talked, she slid her hand further until the tips of her fingers were under my waistband. She gently ran her fingers through my pubes and I got hard as fuck. She often rubs my chest but has never done anything like that and I was frankly shocked. I was also hoping she would just grab my dick and start stroking. Occasionally, she would kiss my neck and positioned her nose so she was constantly blowing air into my ear. At one point in the show, there was a scene where the characters romantically kissed. When they did, she whispered, "I hope you kiss me like that tonight..." My breathing sped up and I began rubbing her hand and arm. She moved her lips so close to my ear that when she spoke, they lightly rubbed it. As she rubbed my upper body, I grabbed her arm and held it close. She was still running her fingers through my pubes. Then out of the blue, she asked if I knew where the remote was. I moved and started rummaging through the couch cushions to the side of me, but he kept her fingers under my waistband. After a couple seconds, with her index finger and thumb, she grabbed the very tip of my engorged dick and with her lips touching my ear said "That's not it... Is it?" I was stunned and didn't know what to say as I throbbed against her fingers. She glided her fingers down my shaft once and all the way back up to the head where one of her finger nails was ever so briefly snagged. She continued, "No, that's definitely not the remote, it's your penis, which feels extremely hard." She then pulled back and told me to follow her to her bedroom.

We laid facing each other, still in our underwear, and she looked down at my cock, which had now popped out of my boxers.

She giggled, "You took your penis out, didn't you?"
"N-no, it just popped out, I didn't mean to. I'll put it back inside," I said as I started to stuff my dick back into my boxers.
"No it's ok, I was just surprised. I haven't really had a chance to look at it anytime recently," she said, staring at it intently. "You know, even your penis looks like your father's."
"What? You remember that?"
"Of course I do. Seriously, it's almost exactly the same. Only difference is you're a little bit thicker. With him, my thumb and forefinger could easily close around it. I can only just barely get them around yours."
"Oh..." I replied, a little stunned. My cock is very average, I guess a bit on the thick side.
"You even trim your pubes the same way. Your testicles hang exactly the same. You have the same vein on the side of your shaft. I bet your cum even tastes the same."

Ok now I was going crazy and my dick felt it was going to explode. I was hoping she would reach out and grab it, but instead she grabbed my balls and tugged gently on them, saying "Go ahead and stroke it for mommy, baby." I started stroking like a madman and she continued to tug and rub my balls. Within a couple strokes, I came all over her thong. I tried to press into her thong covered pussy, but she pushed me back. After that, it was like she came back to her senses and quickly told me she had to clean up and shooed me out of her room. I've tried initiating something again but she seems to not be into it. She still walks around in very little and we make out almost every day but she won't let me touch her tits or pussy. I've tried putting her hand on my dick a few times but she always pulls back. It honestly seems like maybe this just happened because she missed my dad and I guess I happen to look like him. Any advice for how I can get that to happen again?
