"AHH!--" he suddenly cried out as he felt a sharp pain in his ass. Mike had come forward and bit one of Bobbie's succulent mounds, getting a big chunk of that robust man-meat in his mouth and biting hard while licking it with his tongue. He enjoyed hearing Bobbie's pain. He knew the bitch liked this. His thick, hard rearcock was inches from his face. Biting his ass had made Bobbie hump into the bed, which just made his rearcock just out further and show more of its hard length.
Mike palmed Bobbie's other glute, then squeezed it hard as he released the fleshy right mound from his mouth and roughly licked that bulging ass cheek from the bottom where it met his thick, smooth thigh all the way to the top where it ended at his smooth lower back. He then put his other hand on that right glute as well, and with hands on both halves of Bobbie's ass, he assertively pressed his thumbs into the valley between them. He pushed his thumbs in right over the anus, and pulled those firm fucking mounds apart, exposing Bobbie's beautiful, smooth crack and closed anus. He relished the details you'd never get from porn, like the depression that formed around his thumbs where they pressed against the insides of the coiled glutes to pull them apart, the feel of that firm flesh, its elasticity, its robustness. Seeing his deep crack so up close, the curve where his separated glutes met in the middle...
He stared at the incredible view of Bobbie's split glutes and what lay deep between them for a moment, taking it in, then did what any man would do and pressed his face hard into that ass, licking extremely hard all the way up the length of the smooth base of his crack. "MMmmngh!" he intoned in deep lust.
He then looked at Bobbie's clamping, tight anus, thrust his face into his ass again and licked it hard. "Ohh!" Bobbie moaned high-pitched like the bitch he was "behind closed doors" (hah). Mike then thrust his tongue hard against Bobbie's closed anus, pressing and trying to force his way in. After a few moments of impatient trying, lusting wildly after this ass, he lifted up and bit Bobbie's right cheek hard again, while shifting his left hand to palm Bobbie's other glute, this time digging his nails into it painfully. "AAAH!--" Bobbie cried out again.
Mike shifted back and thrust his face into Bobbie's deep ass again, now digging his nails into both of Bobbie's fucking sexy glutes, and tongued his anus again. This time, Bobbie loosened his anus and Mike's tongue slid inside. He grunted loudly as he pressed his tongue around the inside ring of Bobbie's gorgeous anus and then tongue-fucked his cockhole. It made his 9 inches dangerously hard as it hung in the open between his legs. "Ugh, ugh, oh, ughh," Bobbie kept moaning with each thrust into him.
His aggressive partner pulled his tongue out of his ass and dragged it down the base of his crack towards his rearcock, jammed as it wa against the bed. Bobbie moaned intensely as Mike then mashed his lips into Bobbie's plush, smooth sack and licked it, feeling his balls with his tongue, and then dragged his tongue slowly and firmly down the full length of the underside of the shaft of Bobbie's penis, then back up, going back over his balls, kissing them and mashing into them once more, then up to his luscious ass crack and again jammed his tongue inside of him.
Every instinct in his body raged with a pure and simple burning desire to PENETRATE this bitch repeatedly, aggressively, in every way, every moment.
Mike pulled back from Bobbie's ass, repositioned on top of him and held himself up without any contact so that Bobbie couldn't feel what he was about to do. He abruptly and quickly plunged the entire 9 inches of his hard erection all the way into the tight hole he'd been tonguing, feeling intense pleasure as Bobbie's anus was pushed open and then fully wrapped around his cock again as he applied pressure to overcome its tightness and slide firmly through it all the way inside and bottomed out. Bobbie's anus would close up so tight every time Mike pulled out of him that when he'd "plunge in" anew, he couldn't exactly ram him and he could only sink in over a few seconds.
"Uhhgh!" Bobbie gasped and cried out momentarily in shock at being taken so fast and unexpectedly. Then, moaned "ohhh--" as he was suddenly entered, and "ohhhhhhhh..." as he felt every single inch of that cock slide into his tightness and smoothly penetrate him all the way to the base.
Mike leered as he watched Bobbie's glutes, which weren't being pulled apart right now, separate and close around the cylinder of his cock right where it disappeared between them on its way to his anus, then watched that smooth flesh press inwards as he forced his way in.
As he bottomed out, Mike's cock twitched inside Bobbie as he felt the lusty pleasure of his body come into contact with his thick ass and then felt those amazing glutes compress against his pelvis. A moment later, his cock twitched again as he felt his heavy ballsack come into contact full-on against Bobbie's perineum, the underside of his sack rest against the top of Bobbie's own plush sack, and the left and right sides of his sack surrounded by and rubbing up against the skin of his smooth, thick thighs where they met.
If he'd been a lesser top, he'd have choked on the pleasure and dominance of it all. Man, fucking Bobbie from behind was as good as dominating him from the front. Being the top he was though, he just felt a continuous, burning wave of aggression towards Bobbie's thick, curvy, firm, and smaller 5'5" body that was so surprisingly smooth all over.
"Yeah, you like that bitch?" He pulled back and then slid his cock into Bobbie again, making him moan and pressing him and his rearcock firmly into the bed. He finally was able to start ramming into him from behind with the power of his muscular glutes. He rammed him again, and again, and again, grunting hard each time as he now got lost in rhythmically slamming his thick meat home and compressing Bobbie's fucking gorgeous glutes each time.
Damn fucking a bottom from behind was good, so degrading.

An Aside:
Let's "compare and contrast" fucking a bitch from behind vs from the front.
What Mike was enjoying so much with Bobbie here, like with other bottoms he fucked, was that going from behind is completely different from the front.
From the FRONT, fucking a SUPINE bitch as in PARTS 1 AND 2 of this story, or a slutty COW-"GIRL" bitch, there's an opportunity for some kind of fucking connection -- be it dominating, vicious, predatory connection like Mike enjoys or fucking bullshit romance -- if you cared about your bitch that much. That's for those FUCKING RAINBOW GAYS. But you ARE facing the bitch. You can SEE their faces while you do shit to them. When they start MOANING IN PLEASURE and it TURNS YOU ON, you can JAM YOUR TONGUE down their throats like they're real women while you're simultaneously PENETRATING them below. You can SEE THEIR USELESS COCKS to see how they're RESPONDING. It's also an inherently receptive position, where the bottom can more obviously ACCEPT and RECEIVE.
Now, fucking them from the OTHER direction -- FROM BEHIND -- it's implicitly and explicitly DOMINATING in every fucking way.
It's COMPLETELY IMPERSONAL. There's NO OPPORTUNITY for personal CONNECTION. All you can see is the BACK of the bitch's HEAD. Their FACES are out of view! I remember a JOKE when I was a teen that they put missing photos of gay bitches on VASELINE jars, but rather than the bitch's face, they'd put up a picture of the BACK OF THE BITCH'S HEAD. Their COCKS are out of view too, and you can FUCK them without ANY IDEA whether they're enjoying it or HATING IT. When you CHOKE them, you can't see their faces, which feels more LIKE IMPERSONAL, ANONYMOUS RAPE than frontal rape where you want them to see you and connect with you as you force yourself on them.
You can FUCKING OVERPOWER AND DOMINATE SUBMISSIVE BOTTOM BITCHES with your strength and weight. It's much easier to PENETRATE them. You can be ON TOP OF THEM. You can fucking control them. They can't GET AWAY. You can HOLD THEM DOWN with all your WEIGHT and your MUSCLE on top of them, your arms against their smooth backs. You can be on top of them and FUCK them INTO THE BED or floor. You can BITE submissive bitches PAINFULLY while you HOLD THEM DOWN. They can't even begin to get back up by pushing their asses back, because your THRUSTING ASS MUSCLES are MORE POWERFUL than the muscles they're using, so they CAN'T GET UP. You can PIN them PRONE or AGAINST A WALL. That double-entendre there is real -- you pin them down like in wrestling while you stab into them with your thick cock.
