Jake decided to stay on his back. He wanted Ben to see his good work, and his face would be a very clear indicator of exactly how good it was. As his hole was teased, Jake's face changed into something that resembled Ben being fed on, a hyper stimulated state that might suggest to Ben Jake started his sex life in this role, not the one he'd been taking up to this point. Every small step Ben took to get Jake ready made him moan, twitch, and look at Ben like he was an answer to a prayer.
The first initial thrust was a little painful, but Jake had much worse discomfort in his life, and it was replaced immediately by the pleasure of how Ben fit in him. Jake felt that puzzle piece like connection too, but knew it was as much their physical organs fitting as it was the blood they now shared, happy to connect with itself once more. It would always be like this now, hotter because of the bond. As Jake thrust, he'd find Jake sensitive and hyper stimulated. He had to place his palm in his mouth to muffle his moans of pleasure, and his eyes said both thank you and more in a single expression. "Harder," he said softly, wanting Ben to punish him a bit more than Ben might feel comfortable doing. His hands reached out to grab Ben's sides, but he was a bit too short, so so sat up a bit on the table, using his arms to support himself without having to make Ben exit. Now they could kiss if Ben wanted, or he'd at least get to his lover's pleased face up close, a greed that almost seemed to match his own. Ben might have a guess how Jake had reacted to the bite back in the day.
