Mum was squirming under her sister's mouth and clutching at her own breasts, she looked as if she was in agony but I knew she was enjoying it, I leane... over and kissed her deeply, her tongue snaked between my teeth and she sobbed,"Strip for me Anthony, take all your clothes off darling, I want you naked"I practically tripped over myself in the rush to get naked and mum gasped when she saw how my penis reared up to almost touch my navel,"Oh fuck yes" she whispered, "Look at all that"Moving. At that point, I began to saw into and out of her ass, alternately stretching and emptying her asshole. She began to whimper, and started to stutter, as if to ask me to slow or stop.

It stings like none other, as I try to muffle a scream. Another blow and I can't help it as a yelp escapes my lips. Another blow and it starts to almost feel good.

He'd actually gotten finished dressing first and then he'd stolen quietly down the hallway of their home and watched as Samantha had gone from being naked where he'd just finished eating her pussy to getting dressed gradually as she slipped on her panties and her bra and then the top and pants she'd put on to go to classes. He'd had that vision of her moving from totally naked to fully dressed in his mind all day long and Pete had known he was the only person in the world who enjoyed such.
