Girlfriend's Muscle Growth Bet - full vid on ClaudiaKink ManyVids!

Your girlfriend Claudia tells you that she wants to try and put on some muscle – she saw some female bodybuilders on TV the other night, and it inspired her. You can’t help but laugh – Claudia is a skinny gamer girl, and you don’t think there is any chance of her putting on muscle like that! She gets annoyed at your laughter and tells you she bets she can get just as muscular as you – but probably bigger, in fact! You smirk, and tell her she will never be as strong as you. She challenges you to a bet, saying she is sure that after three months of hard work she will be bigger and stronger than you… when the three months are up and Claudia takes off her sweater to reveal her biceps, pecs, and delts, you realise you might have made a mistake.
