She needed fucking. A glint in her eye meant I knew she was up to something. She turned round and got on to all fours and headed the mirrors they have...at floor height. Her tits swaying as she crawled. Her arse was too tempting a target and I slapped it. Louise gasped again and I could see into her eyes from the mirror "Fuck me you bastard, I want to feel your cock deep inside my aching pussy". Who could turn down an invitation like that? I knelt behind her and guided my cock near her pussy.

I can almost guarantee it.” he soothed. Steve moved the head of his cock over my wet slit back and forth to lube his very large cock. He pressed it against my rosebud and slowly he started to enter. Like two spoons...' me in front and him behind me lodge deep in my butt by his remarkably huge phallus. Gary slowly turned over on top of me pushing me below him as he did so.
