No Way Back by Unknown

as Drum slowly penetrated past the ring of muscle in his anus. The smooth cock stretched him wide. Drum paused until Jake nodded to him to continue. He could take him.
    In smooth, easy prods, Drum worked his way in. Once he’d settled in a good bit, he rubbed Jake’s abdomen until he relaxed. Then he began to stroke. Long and even at first, building into short powerful thrusts. Jake grunted with every jab. Each thrust in burned, hot and heavy, shaking his whole body. Each slide out set his nerves on fire. He swore the deeper Drum pushed, the tighter the fit. He could barely breathe; his lungs felt like they’d slipped up into his throat.
    Getting fucked was the oddest sensation he’d ever known, and it drove him wild. He liked the way Drum held his legs open wide and impaled him, stroking in and out, in and out. He watched his eyes, so intent before, glaze over with passion. Drum’s lips parted and he could almost see the moist breath puffing out.
    Jake tweaked his tight nipples, as if that would settle the ache there, and then he grabbed his bobbing cock and began stroking. He wanted to come too.
    As he clenched his ass muscles, Drum seemed to expand inside him. His lover was stroking less and nudging more. Oh yeah, Drum stuffed him good.
    It seemed as though the humidity in the cave turned to steam from the slick heat of their rocking bodies. Pricks of light danced beneath his eyelids every time he blinked. Oh God, he was going to come. Soon. Very, very soon.
    Like him, Drum panted audibly now. “Jake --” He leaned forward and shoved, harder and harder. His heavy breathing turned into deep grunts. Drum threw his head back and cried out in his native tongue. Deep inside, wet warmth rushed into Jake.
    He shuddered. His body tightened.
    Drum ran his hand over Jake’s drawn up balls and crooned to him in unintelligible Alishon.
    Jake picked up that one phrase that he said a lot -- Equitash benini . He’d have to ask him what it meant.
    Later.
    Oh, God!
    He let his orgasm go with a long groan. Blazing stars! His semen arced over his head. His body shook as he exhausted his climax. One last spasm dribbled his milky cum over his fingers. He released a long audible sigh. As he settled back into reality, he focused on Drum caressing his inner thighs. When he could see clearly, he returned the satisfied grin on his lover’s face.
    Holy shit, that was good!
    Drum leaned down between his legs and gave him a quick kiss. Jake only had enough energy to smooth his hand over Drum’s muscular chest. Why had he fought this for so long? He felt as if he was floating. With his hands on Jake’s knees, Drum slowly pulled out. He seemed a lot bigger than going in. When Jake looked, he almost choked. The pink head of his cock was bloated. It deflated as he watched, but it had been huge!
    No wonder it felt so tight.
    He thought back to the blowjobs he’d given Drum, always in the dark, and the strange tightness he’d felt at the back of his throat. He’d thought the fullness he’d felt was caused by the narrowing passage at the back of his mouth. What did he know? Sheesh , Drum could’ve gagged him with that thing.
    Drum smiled at him. “Evolution is a wonderful thing, no?”
    “Huh?” He sat up, sore from resting his back on a rock.
    “Are you all right?” Drum asked, moving around him and examining his back. He squatted behind him and gently rubbed where it stung the most.
    “Alishon penis heads expand to ensure no seed escapes backward in the channel.” He kissed Jake’s upper back. “Even for us, this is important.”
    After a quick shoulder squeeze, he returned to the pool, dipped down and rinsed off.
    Jake jumped in beside him. His butt hole ached and the cool water soothed it. “Why is that?”
    “I give you my essence, which mixes with your body fluids. After several matings, it will build up and find its way into your sperm. Then when you mate with an Alishon female, your sperm will be more compatible.”
    “And
