As I had told I am a 18 yr old boy and 4 members in my family mom dad and my bro 3 yrs elder My Chachi used to live in another town. She was pregnant ...nd was had delivered a baby recently. My grandmother was not that well to take care of her properly so we called her sister for support and help and to take care of her.I had completed my board exams and I was free to tour here and there so I decided to visit my chachi. Next day only I went to her place which was 5 hrs journey bybus. I reached. My attention to the wifes pussy was met with a groan of pleasure from the wife and she started to grind her pussy on my face. I assumed that husbands cock was free of his speedo and wife was sucking hard on it.After a little while husband told me that I could fuck his wife from behind if I wanted to. I was still super horny but I had cooled down a little bit and thought that I wouldn't blow my load after two strokes so I grabbed a condom and got on my knees behind wife. Sure enough husbands. Jab hum ghar me akele the tho meri bahen ne mujhe pucha “kya tujhe koi ladki pasand nahi he kya”.Tho maine kaha mujhe bahut ladki pasand he lekin 1 ladki mujhe bahut aachi lagti he.Tho usne mujhse naam pucha woh ladki ka.Tho maine kaha agar me bol diya tho tum mujhse gussa ho jaogi.Meri bahen ne gussa na karne ka wada diya aur kaha ki ladki ka naam batao.Tho maine “krishna” naam bataya.Tho bahen ne bola ki “meri frd krishna kya”.Tho maine “ha” keh diya aur woh shock ho gayi.Use kuch samaj nahi. There was no thrusting. She just moved her middle around mine.“A little overeager, wasn’t I?”“It was hot,” I replied.“It’s been a while since I got off. You do it so damn good for me.”“Thanks, but you deserve more credit than me. I’m just a dildo,” I laughed.I widened my legs and pushed her legs together to tighten her cunt around my cock. She continued to move in circles lazily. I raised my knees and with my feet flat on the bed, I started a slight stroke up into her pussy. For several.
