Caught jerking off by my cousin with her dirty pa

i live in the same house with my cousin and her husband,i was home alone and horny,so i got my cousins dirty panties from her hamper and went to my room with them,i started sniffing them all to find the best smelling pair.so i took off all of my clothes and laid on my bed with them,i put one pair over my head so her crotch was close to my face and nose, i put one pair on and the other pair with my cock hanging out jerking off with them around my dick.i was fucking loving every minute of it.well low and behold she came home early from work and i didn't know it,i didn't hear her come in.my bedroom door was half open.there i was sniffing and stroking my cock to her dirty panties,she was at my doorway,she must have been standing there watching me for a few minutes and i didn't know it because her panties were covering my face.i heard my door open and there she was with her pants and panties to her knee's,she said what the fuck are you doing with my panties to me,i couldn't say a word i just laid there with my dick in my hand.i thought she was pissed until i saw her pants were down,so i just kept on jerking.she stood there finger fucking herself watching me,i could hear how juicy she was by the sloshing sound her fingers were making.she came over to my bed,i took her panties off my head and got up,she got on her knee's over the edge of my bed,i stood behind her and fucked her so hard i could feel her pussy clamp down on my dick as she was cumming,she said you like my fucking panties now fuck me like you do.my dick and balls were soaking wet i could only last for about 10-15 minutes.i pulled out and shot my cum all over her ass then stuck my dick back in her and fucked for a few more minutes.ever since that day,she gives me a pantie flash and shows me her pussy when no one is looking.now every once in a while she will leave her dirty clothes in the bathroom after she showers just long enough for me to pretend i have to use the bathroom right behind her when she is done.when i come out she just smiles at me.
