The parts of Raju that can focus at all are so focused on restraining himself at least a little that it takes him a moment to realise the parted lips for the invitation they are. Once he does, without hesitation he bites Francis' top lip. Thinner than Seetha's, which makes this a new experience again; he can take it between his teeth very easily, and makes an approving, satisfied noise as he does. Then he turns his attention to the inside of Francis' mouth but he wants a different angle, and moves around without breaking the kiss to lift a knee onto the armrest. He isn't sure where exactly he's going to plant himself once he climbs over, because there didn't seem like very much room on the chair that Francis wasn't using already. But where there's a will there's a way, and Raju's will just now is very strong. He's going to figure it out.
