My wife moved around behind Erik and played with his balls and ass while he fucked me, it felt like he was getting harder and that he might be ready t... cum. I turned my head to ask my wife, “Do you want him to cum in me or you, hon?” As she worked his asshole with a finger she said, “Mmm, you got his load yesterday, I get it today!” Erik smiled at this and pulled out of my gaping asshole.“Where do you want it?” he asked her. She came around next to me on all fours and said, “in my ass!” . She was very sexy and also attractive. I would always fantasize her while masturbating. I always wanted to fuck her desperately at any cost. But I waited for suitable time.Since I was little shy type I would just smile at aunty whenever she smiled at me but never tried to talk with her or with her daughter. Once my mother came to my place for a visit and she stayed with me for few days. During her visit she made friendship with aunty so I came to know about their family details.Once during chat. We sat down and Dean said, "you're gorgeous in that outfit and those feet are to dies for."We started to kiss and rub each other. Dean's hands were all over my legs down to my feet. He admitted timidly that licking feet full of cum was another fetish of his and that no one has ever asked him to do that let alone in an office setting. I said, "tonight, it's all about me and not about you." Of course, with the gist of things, it would get his cake too.He continued to rub my legs and I said:. As days were passing i was not getting interest in anything.My sister became normal with me and she noticed me losing interest.she asked me to forget about that and behave in a normal way.she told me these are common at your age.And as days passed i became normal.But mu desire to have my sister anu did not change.I used to see her changing dress. i was playing with her undergarments and wear it and shag on it.Now i again wanted to touch her.this time i was touching her hardly. she used scold.
