Oh, I thought, she's in the shower.Then we DID 'do it' last night, I realized as I lifted the sheet to look down at my shriveled cock. It looked crust... this morning, coated with the dried concoction my both mine and my sister's sexual secretions.Gosh, I thought, wiping my brow and sitting up. I wondered how Ellen was feeling, after what we did last night together, and why she wasn't here, in the bed, to greet me?Then I suddenly realized what this was probably all about and a sense of fear and. I kissed my way to her neck where she smelled amazing. I have always been a sucker for scent and hers sent chills throughout my body.

Tess must love nipple stimulation because the second I began sucking on them she started moaning and pulling my head closer for more. I brought one had down to play with her pussy at the same time and felt she was soaking wet. I. Moans erupted from throats. Frantically she pulled at my pants. I slid her dress high on her hips, pulling at the tiny panties. The strength of the fabric failed against the passion of the moment as I tore the panties from her body, stuffing them into my jacket pocket.

She couldn't do anything but surrender to Matt's delicious finger-fucking. As he pistoned his stiff finger into her boiling little cunt, she pumped his thick throbbing cock. Mother and son went at each other frantically, both horny out of their minds. Donna felt herself rocketing towards orgasm, and Matt felt his balls swell till they threatened to burst. He also felt the inside.
