"Fuck my sister in the bum," said Lorraine to me.

Lorraine looked and then got a dirty look in her eyes. She put each of her hands on her older sister's ass-cheeks and pulled them apart, giving me a clear view of her puckered asshole. I took the hint and started rubbing my thumb around her star. She started cumming again.

"Fuck my sister in the bum," said Lorraine to me. I didn't need to be told twice. I pulled out of the teenager's cunt and lined my cock up against her sphincter. Debbie had moved out from underneath her cousin and was now watching what I was doing. All of a sudden she asked Judith if she'd been fucked there before.

"No, never," her cousin replied. "But now I want. Do it, Roger." Before I could push my cock in, Lorraine grabbed hold of my dick. I looked at her, a wild, **** look in my eyes. There was no way she was going to stop me doing this. She looked at me seriously. "Slowly, you big fucker. All right?" I nodded and she looked down to line up my cock with her sister's asshole.

Judith wasn't about to tense up now. I worked my cock-head into her tight hole and then slid the rest of my dick in quite easily. It was unbelievably hot and tight and I could feel her tunnel throbbing around me. She'd gone quiet and was just breathing heavily, occasionally emitting little mews of pleasure. Debbie was stroking her cousin's back and checking she was ok. My attractive neighbour just nodded, sweat spraying from her long dark hair.
