Not your normal Backpack (Patreon)

(All Characters Depicted are 18+)

Dani might be an idiot sometimes, but hes actually pretty good and making things in Alex's workshop. The things he makes always have some kinky element to them though, because of course the perverted little femboy wouldn't make normal things.

Issue he has though is he usually has no one to test his little inventions on, other than himself anyway. With Leo living with him now though it means he has a kinky little guineapig, I mean, assistant, to help him.
Now unfortunately Leo got the wrong idea when Dani asked him to give him a hand. Saying "Can I f*** your butt in the workshop". Leo naturally thought Dani meant with his own dick. (which would be a little difficult as Dani was still wearing the flat chastity cage from last week.
Anyway in the blink of an eye Leo pretty much tore his clothes off. Then happily skipped to the workshop wearing nothing but his cute Bi stocking, collar and his shoes.
When there though Dani explained that he wanted him to test his new invention. Leo, was a little disappointed.. he'd even grabbed a hand full of condoms.
however Dani's invention wasn't any normal invention.. he quickly shoved it on Leo's back and tightened its straps. Then positioned the dildo against his butthole, before rubbing lube all over it, and inside Leo, which made him a little happier. He didnt think much of Dani's invention though, mainly because the last few inventions Dani had tried on him failed.. one even requing a trip to A&E, and to awkwardly explain why he had a padlock, with a broken key, locked around his balls.. This invention was a little different though, it actually worked!?

Anyway hope you like the artwork ^^. I came up with this idea while trying to build my of F machine haha. And yes I would happily wear that backpack if Dani gave it me :3
Hope you guys are well <3
