Twins Sam and Amanda Marchant secretly swapped roles in a kinky sex game to see

Computer designer Lee, from Biddulph, Staffs, first met the stunning twins, now 18, in a Stoke nightclub last year. They kissed two nights later and by the next date they were lovers. That first sex took place at his dad's house - when the coast was clear.

"I can remember stripping her off and I was amazed by how stunning she was," he smiled.

"Her figure is perfect, luscious legs and a perfect, pert bum. I couldn't believe my eyes, or my luck!

"I took charge that night, but after that she became insatiable. We couldn't keep our hands off each other. She couldn't get enough. She even took sickies off a part-time shop job so we could be together."

Screeching Amanda and Sam have taken the BB house by storm with their matching outfits and plans for a 'man sandwich' with a threesome in the house.

They have also been nicknamed Dumb and Dumber, though it's often unclear which is which.

Lee added: "They were always dippy. Amanda thought Dublin was the capital of Germany.

"And they say they want a man sandwich, but the only sandwich I saw them make was a 'Sammy's Special Sandwich' which she'd make thinking it was a amazing creation. It was bread with cheese and lettuce!"

Pals have told how the sisters love dressing up to hit the town, especially in nurses' and bunnygirl outfits.

"I remember buying Amanda a Miss Santa outfit for Christmas," said Lee. "It had a short, sexy skirt and a fur-trimmed hat.

"Amanda called me up a little while later and said, 'How do you fancy shining Santa? She put on an incredible private performance for me--she's a real exhibitionist.

"Both of them have great figures. They eat rubbish all day, their favourite drink is WKD alcopops, and they never exercise, but they're naturally slim and curvy.

But while the girls were inseparable, catfights could erupt
