Although married at the time my then wife was not at all interested in sex so I looked elsewhere.After a few weeks I was contacted by the male half of... a couple interested in a MMF bi meet. The photos on their profile were good but nothing special so I wasn't particularly hopeful. However we exchanged email addresses and they sent some private pics that they hadn't posted on their public profile. As I opened the first email I was astounded. The wife was absolutely beautiful; firm shapely. I could feel myself cumming hard all over his cock.'Mmmm baby, you know I love it when you do that' the stranger said as I felt him cum inside me.Oh my god, no. I couldn't believe it, pulling off the blind fold, I lay there in horror.'Get off me, what are you doing you fucking idiot? He will be back any second I'm sure, what are you doing here, like this...?''It's the only way I could see you without us being found out, don't you get it, I wanted you so badly, and it was the only way.''But how,. I cursed myself again but she turned back, saw me and gave a smile as if correct thing happened. I was relieved that she was not angry at me. Later when our house approached, my s*s also got down the car and said to her hubby that she will stay with us for couple of day and come later.Her hubby nodded and left the place with his mom. I was afraid if my sister is going to complain about the incident to dad, but it didn't happen. The topic didn't come at all. I went to my sister when no one was. Stared licking her pussy like a wild dog…oushh uhhh suhhhh shyam uhhhh…..She pushed me to bed….Licked my whole body. Nipples and chest…Loved my body as I don’t have any hairs, I asked her to lick my armpit orderly she licked like a mature armpit licker, then she started pushing my cock…It was paining so hard…i asked her to lick my asshole smell my smell lick it bitch so as my demand she did all.It’s show time shyam lets fuck, she positioned herself cowgirl, ohh man she banged me like a cow uhhh.
