this normal? my mom had really really rough sex in an extremely small foldup camper while i was in it. we were camping and we werent even 10 feet away from eachother with nothing inbetween us but my curtain (theres wasnt closed thankfully and i seen it all, i got to see my mom take it hard for at least an hour while pleasuring myself and i couldnt have been more turned on. im not joking, they were seriously rocking me off my side onto my stomach or back all night from the thrusting. i got really turned on by it when i first realized what was starting to happen so i pulled out my mp4 and recorded the sounds. is it normal to get turned on by this?
