[To be honest, Hiccup hadn't quite expected it to be reversed like this. With him only just recently accepting his sexuality and with how their past experiences had played out, he had only just assumed, had only thought about himself being inside Jack.
But this--the way Jack describes it to him with such arousal, the way he grinds up against him, feeling that erection pulsing even through fabric, he was suddenly aching for something new and unanticipated. He didn't want to just feel it in his hand or against his body--he wanted Jack to feel him inside.
He swallows hard, terrified but yearning for it all at once. But he moans loudly against the thrusts (since Elsa seemed to actually encourage it, he didn't bother controlling his volume anymore), and speaks in a trembling whisper.]
