I (15M) slept with my stepmom (37F) and I liked it

I have a great relationship with my stepmom (37F), she is very young and my father has a 10 year age gap with her, the age gap isn’t even bad but she looks very young for her age. One night my aunt (46F) from my birth mom’s side came to visit, my house is a 3 bedroom house but one of the bedrooms is workout room. My dad happened to be out of town, and so we agreed for me to sleep with my stepmom so my aunt could sleep in my room, I cleaned my room up and made it nice for her and she loved it. Once it was time for bed I climbed into bed with my stepmom and she started watching a movie with heavy sex scenes, I tend to hate movies like that but I brushed it off and put in my AirPod and watched TikTok, my step mom seemed lonely and she kept looking over at me, she then started to cuddle with me but I brushed it off thinking she was giving me love like a loving parent does, then she put her hand under the covers and started rubbing my shorts where my private part is, to be really honest I really liked it because I’ve been super lonely lately, she continued to do that and she started to cuddle more with me, after a while we we went to bed and she was still cuddling with me. I woke up the next morning and she was already out of bed making breakfast, and ever since she has acted like nothing happened. I know this isn’t normal but I really liked it.
