Classic Saigenos interactions I always love seeing, that are unique to their dynamic :’)
Because of the inherent nature of their dynamic, with Genos as Saitama’s self-proclaimed student, they typically interact in a balanced, healthy exchange of devoted, eager appreciation and spontaneous, nurturing guidance. As an active, assertive disciple to a passive, but natural master in domestic equilibrium. Atypically shifting the usual power scales of authority, where now both of them can interact on more equalized grounds. Such a unique dynamic allows for many ways they can show affection and intimacy as a pair, but some common favs that I’ve seen (even around in fics and art) that work specifically just for them include:
Saitama, the only person able to make Genos smile and soften his otherwise hardened exterior. And Genos, the only one able to make Saitama smile and feel content/loved on some of his hardest days.
Flustered egg, completely at a loss and out of his element knowing how to deal with such passionate and forward affections from Genos, after having lived emotionally numb for so many years. And Genos, slyly using his scanners to read exactly how much he affects Saitama and his quickening heartbeat.
Equally flustered toaster, who ‘glows’ orange-hot and steams even harder the more worked up he gets. Saitama easily astounds and impresses him with nearly everything he does, often taking him off-guard!
Personal heater borg, voluntarily using his body’s unique functions for Saitama’s comfort. It NEVER gets old! Saitama can safely handle any temperature Genos can emit, though Genos still irrationally worries he could burn him.
Saitama effortlessly hefting Genos’ 300kg frame as if he’s light as a feather. Genos strong enough to carry him with ease in return too.
Saitama with expert control over his strength, to not accidentally injure Genos. Genos assures him it’s fine if it happens anyway (maybe he even likes it), as he can be repaired. Saitama still worries about what could happen, and tends to be extra careful regardless. Saitama assures Genos he does not need to be gentle with him either, as he can physically take anything Genos does in reciprocation.
When they hug, Saitama often reaches up to cradle Genos’ head – the place that holds the only organic part of him left, because he likes to cherish and be close to ‘Genos’ too. A touching gesture that shows how much trust Genos has in him – to allow Saitama, a person with that much strength, to handle that part of him with such confidence. In return, Genos often embraces Saitama’s whole body, as though he just can’t get enough of him. Needy, desperate, and possessive.
Similarly, Saitama able to hold and caress Genos’ core directly, with his permission. Again, so much trust involved to handle such a delicate (literally and figuratively) object that constitutes Genos’ heart.
Saitama able to thread his fingers through Genos’ hair, a very self-indulgent act stemming from his bald complex; as it’s the first time in years he’s been able to touch hair again freely. Both of them are so terribly touch-starved; the gesture is just so mutually beneficial, comforting and soothing.
Likewise, Genos holding and stroking Saitama’s head, reassuring him of his insecurities – Genos loves his baldness and wouldn’t have him any other way. Saitama’s perfect just the way he is!
Saitama inspecting Genos’ hands or other intricate machinery because everything about him is such a complete marvel; he’s just absolutely entranced and wouldn’t have Genos any other way either. Easing any self-conscious doubts Genos may have had about his metal body. Genos in turn reciprocating that devotion and body worship, because Saitama (and his perfectly sculpted musculature) is like that of a god to him. That intimate interplay of metal and flesh!
