Your girlfriend comes into your room and doesn't realise you're there as she starts to undress, maybe this is your chance to finally see her big tits topless!? Unfortunately though she turns and with a start sees you, coming over and showing off some new lingerie she's bought. When you ask to see her without she reiterates that she's insecure about her boobs, but imploring that you've been together for a while she finally relents and reveals she's been keeping a little secret... She stuffs her bras with socks! Embarrassed by her superficial stuffing you let her know you've got a secret for her too: you love that she enhances her assets and in fact would like to see her bosom grow even bigger. Enthusiastic she reaches into your wardrobe and pulls out some of your boxers and begins pushing them into the fabric one by one. Her chest expands bit by bit and your dick grows harder with each one that disappears. She shows off her new even more massive rack for you and happily bounces her titties making them jiggle in their huge cups ;)
