sex with my mom SeXStoRY

this story is completely true, i posted this because i was very guilty one day after my mother came home from work, she had a headache. so i applied balm on her forehead, while i was applying balm she moved her hand down my belly and under my trouser and started to blow me off. i got a real boner and removed my trouser and jumped to her body, i unbuttoned her gown and started sucking her breasts and lip kissing her. then she removed her panty and moved my cock inside her pussy. we had sex for about half and hour, then i started to lick her pussy,i think she liked it very much. then i started to lick her all over and cum over her breasts. then something i never thought happened she started to give me a blowjob, it was so fun. after that we went to sl**p when we got up in the morning she was on top of me, still hugging me with her breasts pushing tightly on my chest. but now i don't know what to do, she won't talk with me that much. and i don't know if she is pregnant i had so much fun that day. i am 18 and my mother is 36. this is a completely true story pls help me and tell me what to do. i want to be normal again. :(
