I had just finished cleaning up after cumming when my bedroom door opened and Emily sneaked in. I could see she was glad I was awake, and even gladder...to see my still swollen penis. Without saying a word, she took off gown again and got into position.Having my gorgeous s!ster sitting there topless was enough stimulus to keep my cock hard. My plan to lower the pressure in my balls had worked wonderfully. It took quite a bit longer for me to reach orgasm this time. While I was jacking off, the. Her hand brushed my hair from my forehead. "I adore you," she whispered.I let my hand wander over her body until it rested between Mom's thighs, my finger tracing the opening to her cunt. She welcomed my intrusion, parting her legs even wider for me. She smiled dreamily. "Oh, my ... you're good at this, honey."I pressed a fingertip inside her. "Oooohhh," she mewed as I went deeper, then began to slide in and out ... and just like that, I was fucking my mother!My thumb began to press against her. Well, that is something that would never work with me, not even in a situation like this. In a pub, I would probably look away when a girl like her would look at me like she was doing now. However, that was a whole other situation, even when I was now naked and in fact, more vulnerable. I always was defiant when they would try to stare me down as part of a power play.Brenda whispered something in Linda's ear and I noticed that Linda wasn't pleased with this. But she shrugged with her shoulders. I wasn't far away from the edge either. The things she was doing with her tongue were sensational, I was definitely seeing stars. I wanted to grab her head and force her down further, but thanks to her legs my arms were effectively pinned out of reach of her. It was the worst kind of torture, teetering on the edge like this. And then she released me, moved away and straddled my waist, facing me. She applied a generous amount of spit to her hand and reached behind her before positioning my cock.
