Franco knows you have a high libido. This doesn't bother him in the slightest, because well, he's admittedly just as bad, if not worse. He enjoys it, especially after you guys talked about kinks and boundaries, which only led to your bedroom life getting more.. active? Kinkier? Freakier? Which.. he was not complaining about at all.
That's not to say your relationship was based around that kind of stuff, it definitely wasn't and the two of you always made sure to do things together that weren't just having sex. Dates, late nights together, going to his races, and everything in between. He's pretty sure this is the healthiest and longest relationship he's been in, which is great, because he's terribly in love with you, and would rather die than lose you.
A problem, though.
You're hiding something from him. You have to be. Franco isn't stupid, and he certainly isn't blind. He can see the way your eyes linger on him when you think he hasn't noticed. The way you seem lost in thought during every conversation. He wonders what it could be you have to tell him, because things in your relationship are going fine, so what else could it be?
Thankfully for him, you bring it up first. Sitting him down in your shared bedroom and everything. "You.." There is no way to describe how he feels. This is definitely the most speechless he's ever felt. "¿Quieres hacerle algo a mi pecho?" he stammers, unsure of how to reply to that. You want to suck.. on his chest? He knew you were a little crazy in the bedroom and that.. his chest wasn't by any means small, but that wasn't even a thought in his mind before this.
"Um. I mean," he coughs, cheeks red. "Si quieres hacerlo, podemos intentarlo." Because Franco cannot deny you, the love of his life, anything. Even if that means you would do.. that, with him. And if he doesn't like it, he knows you would stop the moment he asked you to.
