Custom - I've come back from the gym, I'm tired and need something to pep me up really quick, all I've got is this green banana to hand, it's not going to be particularly satisfying. Luckily I have a whole handful of tinies in my compression shorts, they've been there the whole workout and are suitably warmed through ready for eating and containing plenty of protein. Lots of up close chewing and swallowing before finally realising I'd left you on the floor but instead of eating you I decide to put you inside my shorts against my cock for later.
