Fics like your bassline (it's got me feeling fine)

Jim goes into heat. Leonard is there to lend a helping hand. It’s not sex, it’s not even fucking – it’s mating, hard and fast as Jim writhes on Lens cock, pleading and begging for more through his whines and whimpers, screaming fit to be heard down in engineering as Len pistons into him, hard and with no relief, a hand supporting his considerable weight even as his other hand drags down Jims torso to grasp at his leaking, twitching cock. Jim mewls as Len fucks forward, knocking Jim off balance and forcing him into the bed. “C’mon sugar,” Len whispers.
