A very interesting night for me, one that I will never understand or forget. So it was around 1030 and it was a school night and my son just went to bed, my boyfriend was over and he was going to stay the night so we watched tv for a few more hours then it was time for bed it was around midnight or so.I turned off all of the lights as usual and we turned into bed, my room is never fully dark and I have one of those glow lamps I never like it fully dark in the room so it was just light enough in the room you can see everything. My boyfriend asked me if I wanted a massage and I said heck ya he loved my body I have perky full C cups and a nice firm petite body…So after about a 20 minute body massaged I was very horny and so was my boyfriend so we started having sex. It was the usual very nice and I was being very quiet with low soft moans which is very hard to do cause my boyfriend is really huge for me..So as my boyfriend was thrusting me hard and kissing and sucking on my neck I glanced over at the door and oh know I forgot to close it and the door was cracked but I thought oh well my son is asleep.My boyfriend was starting to get more aggresive he was in one of those moods that night and he was really starting to pound me hard and the bed was really squeaking now I just wanted him to hurry up and finish since the door was cracked.My worst nightmare came as a mother I could see my son looking through the crack of the door watching and he was thinking I couldn’t see him but I could, my son who is 17 was just standing there and it looked like he was masturbating.I didn’t know what to do so as I was getting pounded and my tits are bouncing all over I was thinking I don’t want to embarrass him it would destroy him so I closed my eyes as I was being violated by my son and let my boyfriend fuck the shit out of me but I was starting to get aroused .I whispered into my boyfriends ear we need to stop cause my son was at the door watching and something happened because he got really aroused and stated really fucking me hard, he was whispering to me its ok he is just curious let him watch and he was really aggresive on me..I didn’t know what to do or think but I let my boyfriend and son who was masturbating both get off on me being fucked at my expense, my boyfriend kept saying be louder as my moans were low so I was getting louder and louder as he was driving his cock into me so my son could hear me getting fucked hard.For some reason I started getting really into and I was feeling a huge arousal feeling down my body I was so turned on I was screaming so loud saying fuck me fuck me oh god oh god my son was getting the show of his life that is for sure.We then decided to get up doggy style and my boyfriend was hitting it real hard from behind my ass was bouncing from his thrust and he was pulling my hair and my tits were swaying back and forth.. Finally he exploded all over my ass with cum and I could hear my son breathing heavy he must of been cumming as well.It was a weird but fun night and nothing has never been said about it but one thing is for sure I will keep my door open at night.
