Mark adjusted the picture in the computer to restore his human head and tongue, hands, removed his tail, and shrunk the torso cocks down to only an inch long. After Cal helped with Mark's transformation, they both started to get dressed.
"Dude, you can't walk out there like that?" said Mark.
"You need to slide that horse sized cock of yours down the side of your sweat pants first." noted Cal.
"Fine, put this sweater on over your T-shirt and wear these baggy sweat pants." ordered Mark as he threw a large sweater at Cal.
"Can you slide that thing back into you?" asked Cal.
Mark shook his head, "No...I'm too horny."
Both left the bedroom and headed back to the kitchen.
Mark's dad and mom were already eating at the table when Mark and Cal joined them.
"Dad, this is Kay. Kay, this is my dad." said Mark as he sat down.
"Hi, welcome to our house." greeted Mark's dad.
The lunch continued normally. Cal's food tasted the same, but it felt good to lick the food as he ate. The untimely arousal from chewing made it hard to keep his tail coiled around his waist. The precum leaking from his various cocks was not noticeable thanks to the extra protection of the sweater. The faint smell, was very noticeable to Mark as his own thick member between his legs became rock hard. As Mark's mom cleared the table, both Cal and Mark remained seated, unable to get up without showing too much. Mark's father left the kitchen area, and while Mark's mom was busy in the refrigerator, Mark said, "Thank you for lunch" and quickly got up and hobbled to the hallway to his room. As Cal waited for his opportunity, Mark's father returned and began the same question/interrogation session that Mark's mom had done the night before.
Mark's mom brought over a few chocolate squares for them to enjoy while talking. Cal had two of the squares before his whole body shuddered in orgasm, the thick texture and taste was too much for his tongue cock to handle.
Mark's dad asked, "Kay, are you alright?"
Cal nodded, "Yea, the chocolate was really good."
Mark's mom smiled, and wished that the chocolate felt that way for her. "You must really love chocolate." said Mark's mom.
"It tastes incredibly good to me." noted Cal.
Mark's dad began to notice the strong smell and smiled. The two wetspots on the front of the sweater were a surprise though.
Mark's mom looked to her husband, "Let's give Kay a few moments to herself." And both Mark's mom and dad left Cal at the table alone.
Cal slowly got up, and slowly walked back to Mark's bedroom, drenched in his own cum. Mark's parents returned and noticed the small puddles Cal left behind in the chair. "What kind of chocolate was that dear?" asked Mark's dad.
Mark's mom replied, "Hershey's dark nuggets."
Mark's dad went down the hall to Mark's room, and looked in as Cal didn't close the door, to see Cal standing with a towel around his chest, and the tail cock wound around one leg.
Mark looked up to see his dad and pushed the door closed. "Shit.." Mark just repeated the one word. Cal felt a sinking feeling like when he got pulled over for that speeding ticket by campus police. After a few minutes of just staring around at each other, Mark left the bedroom, making sure the door closed behind him. Cal settled into the beanbag chair on the floor in front of the computer, and lost himself in a one-person orgy. Mark returned a almost an hour later.
Mark slowly opened the door, and closed it firmly, then sat down beside Cal, who was sucking off his tail cock at the time. Mark said, "He thinks you are a very strange woman."
Cal pulled his tail cock from his lips, "That's good, right?"
"I told my parents about it. They are talking right now, and will let us know what they want to do." Mark said, clearly disappointed.
"You didn't expect to keep this a secret from your parents did you?" asked Cal.
"I had not though that far ahead" said Mark, who took Cal's tail-cock, and began to suckle gently on the tip.
Cal smiled, "Dude, get your own. They are lots of fun." Mark handed Cal back the tail, and took off his clothes.
Mark smiled as he knelt down between Cal's legs "At least we can walk around naked now." Mark slowly slide his horse sized cock into Cal's tentacle ringed pussy. The two were undisturbed in their continuous sexplay for another long period, lasting almost two hours.
Mark's dad knocked on the door, "Come in." Mark said loudly.
Mark's dad and mom walked in and sat on the edge of the bed. "Damn Mark." said Mark's dad. "Seeing the two of you, I was not sure." Mark's dad took a deep breath, "We will give Cal the details of what we want."
Cal looked to Mark, "You told them it was me?" Cal punched Mark's arm hard.
Mark's dad looked at Cal, "There is no problem Cal. Your dad explained it as good as anyone could."
Cal looked back in surprise at Mark's dad, "You called my parents?"
Mark's mom added, "This is easier for all of us to be able to discuss this openly."
Cal took a deep breath.
Mark's dad and mom got up, with his father saying, "We can talk in the kitchen when you two are ready."
Mark waited for his parents to leave, before saying, "Change be back first before we go in there. I need to be able to screw myself for a while."
Cal pulled Mark's head over for a kiss, and Mark eagerly suckled on Cal's tongue cock. The recent excitement pushed him over the edge quickly as every cock gave several spurts of thick cum, coating the two.
Mark pulled away from the kiss slowly, "This scent, your body, and my lust for more..." Mark crawled over between Cal's legs and began to pump his giant cock into Cal's slick pussy. After a few orgasms took the edge off, Mark and Cal toweled off, their bodies covered in a wet sheen. Cal helped Mark with transforming back into his dog-man body, and added a pussy for his belly button, to match with Cal's navel cock. As both walked into the kitchen, Mark's parents stared at the two.
Cal asked, "So, who's first?" Mark's dad got up, and Cal followed him into the small office Mark's dad used. After a few minutes, Mark's dad came out of the office, and joined his wife back in the kitchen. Mark's mom reached around and felt between her husbands butt cheeks, as a canine looking tentacle-tail cock slowly slid out of his ass, his own cock was now a canine vaginal sheath with no scrotum.The two large breasts Mark's dad now had as buttocks were a surprise along with a nipple recessed in his navel.
Mark's mom stepped back from her husband and walked with Cal into the office. When Cal walked out, a very handsome man followed behind her, in fact, she looked like her husband.
The older couple held hands and went back to their bedroom. Mark looked at Cal, "What happened?"
"She saw what he picked out, and changed her mind." shrugged Cal. "At least they still look normal" he added.
Cal and Mark were very aroused at what they saw, and when Cal sat down on the cold tile floor of the kitchen, Mark climbed over on top of Cal. The two were later awakened by Mark's dad, his pussy sheath now taking in some of Cal's tail cock. Mark and his Dad took pleasure in overloading Cal's ability to handle pleasure. Mark's dad even worked both of Cal's breast cocks, helping to keep a steady dribble of cum from each breast. Mark's mom came in as Cal was whimpering from each orgasm.
"Don't fuck Cal to death, give him a break." asked Mark's mom.
Both Mark and his dad slowly pulled off Cal. Cal grumbled, "More, don't stop"
Mark's mom shook her head, and looked at her husband and son, "You two need to get a mop and clean this up." Mark's mom reached out to pet her canine son, "Your a good boy Mark, a good boy."
Mark grimaced, "Mom...I'm still me"
Mark's mom stepped over next to Cal, and while standing up, slid her tentacle-like tail cock all the way out of her ass, lowering it down to the floor, and then into Cal's cock lined pussy. "Mmmm, it does a body good." she uttered.
Mark's dad looked to Mark and happily smiled, "I love getting some tail." Mark rolled his eyes.
After Mark's mom pumped her load into Cal, Cal smiled as he felt sexually fulfilled. Mark's mom pulled her cock tail out of Cal when her knot shrank back to normal. "Mark, you two go take a shower, I'll help your father finish cleaning." directed Mark's mom.
Mark helped Cal, who was still in a drug like high and unable to walk on his own, back to the shower close to his bedroom. Cal, still able to handle more, and Mark still not done, continued their pleasure fest until both were in an orgasmic haze, and as the haze cleared, both fell asleep.
