I helped her by sucking her one nipple and fondling her other one with my hands. After some time she also had an orgasm. About one hour later we came ...ut and dried ourselves. She didnt get any clothes inside my room so she asked for my clothes. When i was about to wear my boxer, she snatched and said you look better without clothes. She turned back, removed her wet panty showing her beautiful assand then wore my boxewrs. We were on the same bed, me naked and she half-naked. Although her breasts. My sister let out a very surprised sound, part gasp part moan as my palm met the soft white skin of her tight ass. She quickly entered her room and closed the door behind her, an astounded look on her face.I turned around and headed to shower, the slapping sound still echoing in my head. There I masturbated frantically to the images of both my step mom and step sister, mother and daughter, and the sensation of my sister's ass on my hand. I came in seconds, shooting a great load down the. .. she discovered she was asleep. "Goodnight Mel," she said as rolled over and closed her eyes, hoping tomorrow wouldn't be as awkward like the last time they slept together."Headache?" Sam asked the next morning when she heard a groan from her side of the bed. It was the morning now and Sam had been awake for some time staring at the wall and waiting for Melanie to wake up though she would never admit to that."Yeah, a fucking terrible one," she muttered, wincing as she light filtering through. She pushed her hips backward and I forced my shaft deeper into her tight virgin hole until I eventually had the whole dick buried in aunt Kate as she let out a lot of loud moans.Her eyes closed tightly as I slid my penis into her virgin ass. With my hands on her hips I started with slow thrust then speeded up my fucking."AAAAAAAAAAAAAHHHHHHHHH!!!!!!!!"Aunt Kate screamed as she felt my 9" ripping her ass apart. I fucked her as fast as I possibly could. I pulled my cock all the way out then.
