I was about to come and she was also. My chithi shouted at us but I was like kanji varudhu di. She was like enakum. (I am about to cum and she was als...) her mom was looking how I cummed in her and her scream filled in room.My chithi went out of the room. She came in after 10 mins when we were still nude and the act of getting caught made an erection on me. My sister saw that and started to ride me and shouting ammaaaa. My chithi started abusing me which increased my mood to fuck her and tear. So what about today at 4pm?” Hearing that I was literally on cloud nine. I could not reply as words got stuck in my throat and I with some pleasant difficulty said “Yeah sure sure but what about your tuition class at 5pm? Do you think we can do it in one hour and get back to normal?” She thought for a few seconds and said “I’ll ask them to come by 6pm today. 2 hours should be good enough for us.” I agreed and cancelled the call.I was watching the clock every second not able to withstand the. ..”“Ahhhhh,” I moaned as ecstasy began to radiate through me from my aching prick. I was going to cum soon. Watching my sister’s face, I eagerly waited to see the reaction of my imminent explosion.“Oh fuck...” I moaned again, louder this time. I arched my back. My legs shook. I knew that I was exaggerating my lust, but putting on a show for my sister was turning out to be even more exciting than I thought it would be. The more I moaned and shook, the wider Donna’s eyes became. My fist was. I rocked back and forth, fucking and sucking at the same time, three hot, throbbing dicks stretching and stuffing every hole. I was being fucked in the mouth, fucked in the ass, and fucked in the pussy. It was everything I had ever hoped for. Suddenly, I felt the cock filling my ass jerk and pulse, shooting a hot load of warm cum up my ass. I screamed in pleasure, the sound muffled by the fat cock thrusting into my mouth. A few moments later the shaft of the spent cock popped out of my now.
