me and my step mom

so my step mom (39) and my dad (47) have been married for 3 years, but there’s always been this weird tension between me and her, she always bends over in front of me to do “stretches” and she often jokes about cheating on my dad with me, so i decided to ask her about it, she started getting defensive saying that she wasn’t flirting just joking and “i really needed to do the stretches” but i think it was clear to both of us that she was lying so i said “just stop lying and tell me the truth” in a blink of an eye later she got up and left my room (my dad was out at the store but she didn’t know) she started looking around the house in every room and ignored me asking her why, then when she had checked every room she told me to go back to my bedroom and take a lie down, i did so because i was rlly confused and about 2 mins later she came into my room and asked if i liked her flirting with me i (awkwardly) said yes and that instant she took of her t shirt and her huge tits just fell out, my dick grew in my shorts and she started to rub it through my clothing, then she pulled down my shorts and started sucking, from the base upwards, i started to let out little moans and so did she, then i decided to grab her and lift her wet pussy onto my hard penis,she start to ride it while moaning for me, i came instantly and apologised but she said “don’t worry i’ll train you to last longer next time” and with that she put her top back on and left,that was yesterda,right now my dads at work and i’m hoping it happens again
