[As soon as he feels the change in his thighs, in the way he shakes he just rubs his fingers there, parting them as much as he can so Oikawa feels fuller. He sinks his mouth as low as he can too, sucking hard until the back of his throat aches from the pressure.
His right arm presses down to try and keep him steady, eyes shutting as he concentrates on giving him those feelings. on making him turn into a puddle at his hand and mouth, just as being inside him had done for him.
His heart feels tight and lungs burn when he pushes lower the next time he sinks down, eyes opening a slither to peek up at Oikawa's face. He's mostly glad, at this point, he can't go a third time or he might have died on the spot already.]
