“I think it’s time we fucked our little sisters, don’t you?”I nodded to her but was confused on what she meant, then I saw her get up and go p...ck up the bag they came in with, to my surprise it was a pair of underwear with a dildo attached to it. Everything became clear as she slipped on the panties and made her way back to the bed and grabbed Aunt Lisa, forcing her to her knees. Rita looked and me and got in the same position next to Aunt Lisa and rubbed her pussy. I watched as mom got behind. But, Kristen knew how to take down a man as big as Max, by grabbing and twisting where it hurts the most! Max yelled in pain, and took Kristen to the floor. Kristen rolled over so that she was now on top. She took of her shirt and bra, and smothered him with her breasts. She had firm, nicely sized boobs which seemed to fit in a C cup. He finally pushed her off of him, and took off his shirt in a fit of rage. He went to squeeze her breasts, but Kristen ducked and kneed him in the balls. . Now I’m an engineer student. Any girls and aunties want me means plz contact my mail. Id.Now coming to the story; I was not good at studies so she told me to meet after the class. After the class I saw her. She told me to wait in the staff room. After half an hour she came and asked me y u r not studying well. I said that nothing ma’am. She told me that she want me to score more marks because I’m the only boy very close to her. She told me to come to tuition regularly to my home I will teach u.. Incredible!When I began to suck her nipple she froze for a second then pulled my head in tighter. I licked and sucked, alternating between the two. The sensations were extraordinary, but magnified ten times over because I knew she liked it too. She gasped, "Harder, do it harder". I started pulling and twisting the one in my hand and she responded by almost bucking on me.I really liked her nipples. The aureoles were about the size of a nickel with stiff pencil eraser sized nipples set just off.
