Mostly he wanted to know how to actually have sex, I was surprised he didn't know more then he did, I asked why he hadn't watched porn on his computer... apparently his parents put a block on such material, so I became his teacher, I was glad to do it, it totally turned me on. I explained the whole act from foreplay to actual sexual intercourse, pointing at his penis, and my vagina, explaining where he's supposed to place it, even going as far as placing him between my legs with him on top of me,. He used to visit our house to stay here for a week or so. By the by, I am Krishna aged 18 and my sister Kumudha was 22 and yet to be married. Mahesh on his first visit itself had decided to get between kumudhas legs and in fact succeeded to do so long back on one such occasion, I happened to go to our flats terrace and found Mahesh in a 69 position with my sis and both were in heaven even though they disengaged on my arrival they took it as a normal thing. It led to me joining them in future. Me: darling, you are sexy.I placed a kiss on her cheeks and then slowly moved towards her cleavage. What a wonderful sight it was. I kissed her softly. I was hugging her so tightly that not even air could pass between us.I then moved towards her neck and kissed her neck and then her ears. I hugged her from behind and was caressing the soft breasts and she was letting out some moans. I then removed her sari and she was now standing with just her bra and panty. She then said,” unfair. You should. I did and was riding up and down on the beautiful black cock. Brad’s hands were all over her tits and she is riding, I’m sucking his balls. It was unbelievable. She is groaning and I can tell she is getting ready to cum. She arches back and is being very vocal, her eyes roll back and she yells “OH GODDDD!” She rests and slowly gets off, Brad tells me to suck his cock and clean all the juices off. I do and he is moaning how good it feels. He hasn’t cum yet and is still rock hard. He asks my wife.
