Jeff couldn't resist anymore, he started rubbing his wolf cock and kept stroking. Jeff looked at his feet which are now wolf paws, he pulled his leg up and being surprised how flexible he was, he then scratched his ear with his foot paw and went back to jerking off, but he raised his leg again and put his paw close to his face and began licking and sniffing his foot paw, he was overwhelmed by the scent and taste of his foot paw and kept jerking off. Suddenly Jeff heard his brothers door open and quickly stopped and covered his hard knot with a nearby blanket. His brother, Dan, walked up to him and asked, "What are doing?" Jeff replied with, "Nothing, why do you ask?" Jeff terribly hid the tent in the blanket. "Are you jacking off..?" Dan asked, "Uhh..." Before Jeff could say something else, Dan continued his sentence that surprised Jeff. "... Without me?" Jeff asked, "What do you mean?" Suddenly Jeff gets flash backs to when their parents aren't home for the weekend, they have some "fun" together. "Okay I was" Jeff said as he moved the blanket away, Dan started to take off his pants and underwear, he then gets on the couch, right above Jeff's cock. Jeff noticed his little brother's cock was slightly smaller but still kinda big. "You ready little guy?" Jeff said as he held his little brothers hips, "Fuck yeah I am." Dan replied. Jeff thrusted and pulled his brother down, fucking him hard and rough, but Dan hardly made any moans and said "Come on Jeff, since when are you carful fucking me." Jeff could believe he was fucking his little brother but he still went with it and thrusted even harder, making Dan moan loud. Jeff could feel himself about to explode with cum in Dan. "Oh fuck yes Jeff, fill me up!" Dan said as he jerks his own cock. Jeff let out a loud moan as he released so much cum into his brother. Dan as well started to cum a lot on to his brothers face, Jeff just licked some off and began making out with his brother. Afterwards Jeff licked the cum off his brothers cock. "Hey Jeff I'm a little tired, can you carried me to bed?" Dan asked and Jeff replied "Why not just stay here with me?" Dan just nodded and said "Okay bro." and laid on his chest while his cock is still in his ass still slightly leaking cum, Jeff just laid his head down, and before he could close his eyes to sleep, Dan said "I want to be a good slut like you bro." Jeff wondered what he meant by that, he then got sudden flashbacks again and remembers how he became a cum dumpster in his his high school and college, he got kicked out of one of his high schools because of it, he would still sometimes go to his old high schools during lunch in the boys locker room to give the boys a good time, even his parents know this but aren't bothered by it, as long as he graduates, which he did, but his parents don't know what he does to Dan and what influence he has on him, Dan tells mom and dad he's staying after school to study when in truth he gets fucked by his teacher and sucks his cock in exchange for better grades. Jeff shook off the memories and fell asleep. The next morning Jeff wakes up with Dan still sleeping on him and his cock still in him, Jeff tries to wake up Dan. "Morning cutie." Jeff says as Dan wakes up, "Morning Jeff! I slept well, especially with your big cock in me, did you sleep well?" Dan asked as he moves his ass a little hearing squishing noises from the cum. "Of course I did Dan, you hungry?" Jeff asks Dan as his ears went up and he yelled, "Yep!" Jeff then slowly pulls Dan up from his cock and sees cum pouring out, Jeff puts down Dan and he walks to the kitchen while picking fingers in his ass and licks the cum. Jeff noticed he was and still is cumming a little, he then started to suck himself and instantly started to cum another huge load into his mouth and swallowed. "Mmm, so good" Jeff said then left to the kitchen with Dan. Jeff sees his little brother on a chair at the dinner table and asks what he wants. "I want pancakes, with your special ingredient!" Jeff instantly knew what he meant and went on. While waiting, Dan kept picking at his ass and licked the cum, then he jacked off for the rest of the time. Jeff finished his pancakes and placed it on the table for Dan but before Dan can eat Jeff said "Wait, we're still missing something" Jeff said as he jerked off and again immediately cum a huge load on the pancakes, and grabbed a cup and started to cum again in it and putted it on the table, "Here you go kid, enjoy." Jeff said as he went to clean up the kitchen then the living room. "Thanks Jeff, I love your special pancakes." Dan said as he took pieces and ate them with delight, after finishing his pancakes, Dan took a big drink from his "milk" and says "Done!" Jeff enters the dinning room and sees Dan smiling with a cum string from his mouth to the cup, "You're such an adorable wolf." Jeff said as he kissed his brother on the lips. "Too bad you're not full wolf like me, like daddy." Jeff thought about that and said "I'll be right back." He left to his room and typed on the chronivac and completely changed himself into a full anthropomorphic wolf like Dan and his father and made sure no changes happen while this happening, also making half the population of the world anthros as well. After a while, Jeff looked in the mirror and sees himself as a anthro wolf with a more lean body structure. He went back and sees Dan outing away the dishes, "Remind me to clean those before mom and dad get home on Monday." Jeff says to Dan as he rubs Jeff's sheath, Dan replied with, "Of course, wouldn't want to get caught." Both Dan and Jeff went to the living room and Jeff sees his phone light up, he looks at it and it's a reminder that it's time to head over to his old high school and fuck with some guys in the locker rooms before practice. "Hey I gotta go, you think you'll be fine alone?" Jeff asks Dan, "Yeah I will but I kinda wanna come with." Dan asks Jeff as he puts on his clothes. "I don't know Dan, their pretty big and pretty rough, and there'll be a lot." Jeff says as he gets his clothes on. "But I wanna be like you, besides I think I can handle it!" Dan says, Jeff replies, "If you insist bro." They both leave to the car and drive off. They arrive at the school 30 minutes before practice, they enter through the gym and to the locker rooms to see some guys, most of them anthros, a good majority are horses and gorillas while the rest are normal humans. "You boys ready?" Jeff yells while everyone greets him as they know him well, one of the horse guys walks up and asks "what with the kid?" Jeff replies "He's my little brother, wants to be more like me and join me on this." The horse looks down on Dan and pulls down his pants showing his long horse cock and asks, "You think you can handle this kid? I'm not even hard yet." Dan doesn't even say anything, he just begins to rub the horse's cock and licks it all over. "I think he can handle it." Jeff says as he takes off his clothes and walks away where Dan can't see him, but Dan just keeps licking and rubbing, the horse the asks, "Aren't you gonna get to sucking?" As he slowly sits down and spreads his legs. Dan nods and begins to suck the horse's fully erect cock that measures about a foot, can hardly get 6 feet in his mouth, but the horse forcefully pushes down his head, making Dan deep throat him. "It's been so fucking long since I've been off, I hope you're ready a volcano to go off in your mouth." The horse says and he keeps forcing Dan to deep throating his cock, very soon the horse begins to moan loudly as he erupts massive loads down dans throat, he lets go of Dans head but he keeps sucking his cock. "Damn kid, I underestimated you, you can suck and drink cum like your slut brother." Meanwhile Jeff has three horses ramming their cocks in Jeff's ass at the same time while jerking off some humans and sucking one of the gorillas cock, after one of the gorillas cum in Jeff's mouth, he steps away and hangs over Jeff by a bar and makes Jeff sniff his gorilla feet, Jeff loved the smell, he smelled musk and... Shit? Jeff didn't care he still loved the smell, he then licked them and tasted shit from them but loved it. "What did you stepped in ape? Some shit?" Jeff asks and the gorilla says back, "Yeah I did, is there a problem? " Jeff replied with "No problem at all, hehe" he the continued to lick and sniff. Long after Jeff was finished, he was covered in cum and his ass dripping with cum, he put on his boxers and grabbed the rest of his clothes and went to find Dan, seeing him sucking a gorilla off while the gorilla holds him down with his feet. "Almost done Jeff, give him a second." The gorilla said as he kept pushing down Dan's head and finally let out a moan and cum in Dan's mouth, Dan the swallows it and puts on his underwear, and grabs his clothes, the left and got in the car. "Did you have fun?" Jeff asks and Dan replies, "Yeah!" They both giggled and headed home, "I think you earned yourself a good fuck." Jeff says as he drives into the driveway, "Yay!" Dan yells as he quickly went inside. Jeff locks the doors and went to the couch and sees Dan on the couch waiting and waging his tail, teasing Jeff. Jeff got on the couch and puts Dan on all fours and teases him by rubbing his already hard, long, and thick cock on his ass then rams it in him and thrusting hard, Dan moans and jerks off his big cock, Jeff already feels himself about to cum, bigger than before, but before he could warn Dan, he begins to cum his largest load in Dan, "Oh yeah! That feels so good, I love your warm slimy cum in me, just as much as I love drinking it." Dan says as he gets tired, Jeff carries him to his bed, Dan grabbing hold of Jeff while also holding him by his cock. Jeff laid on Dan's bed and feels his cock still leaking a lot of cum into Dan, but he knows Dan won't care because he loves cum in his ass, Jeff then closed his eyes and falls asleep. The next morning Jeff can already hear someone driving in the driveway, it was his parents coming home earlier, Jeff had to think fast, they don't know about what goes on with him and his little brother and they can't know.
