{This story continues the adventures of Matthew Kelly (an eighteen year old high school senior) who has undergone some drastic accidental physical changes that lead to the nickname 'Mr. Bigstuff'. His three female cohorts are: Amy (blonde, mischievous, and thin), Mandy (a beautiful brunette in the mold of Jennifer Anniston & Jennifer Love-Hewitt), and Becky (the short voluptuous thick-hipped red-head). All three are eighteen-year-old seniors in high school enjoying Matt's changed physique.}
***
It was about 8pm when Matt got dropped off by Mandy. Matt was pretty worn out. After three intense orgasms, and the continuing drain that his changed physique had caused he was pretty exhausted. He staggered into the house. His mom said something to him, but he didn't catch it.
Matt had to piss like a race horse. He just hoped he could stay awake long enough to make it to the bathroom.
"Going to lay down mom. Really tired."
He staggered into the bathroom to drain the lizard. There was a naked girl with a towel around her head plucking her eyebrows! Matt stood there with his mouth gaping open at her voluptuous body! Matt's clouded mind finally realized it was his 22 year old cousin Jen! She was a compact petite 5'4" athletic blonde. Jen's dad and Mike's mom (Norene) were brother and sister.
Matt mentally catalogued everything he saw. Jen had a short haircut and a fabulously large firm athletic butt that was perfectly globular--like a bubble. Her breasts were the perfect teardrop shape. They appeared to be a full B-cup, but were perfectly sized for her body. And her snatch was neatly trimmed.
"Inside or out sport, but please shut the door I'm freezing!" Matt stepped outside and shut the door.
"I need to piss," Matt shouted through the door.
"Okay come on in," Jen shouted through the door.
Matt walked in and tried to not eye his cousin's hot body. She had a hand-towel tied around her waste. She had those very perfect legs that were athletic but not muscular. Jen's legs had a gently swell at mid-thigh, then tapered at the knee & hip--like a skaters. Her thighs had a beautiful lovely arc. She had another hand-towel tied around her top, but the bottoms of her tits were edging under the towel.
"Go ahead sport! I won't look--promise!" The toilet and sink face in the same direction and were four feet apart. Matt positioned his back to Jen and faced the toilet and the window. This meant he would be pissing sideways into the toilet, but he was shy about her seeing his cock. He opened and lowered the front of his pants and underwear while the back was still covering his butt.
"How long are you staying?" Matt asked.
"Just the night, I'm gone tomorrow morning. I don't have any classes tomorrow, so I was driving home from college to drop off some laundry and decided to stop here for the night. My dad said I could. It saved me a ton of driving!"
Matt was suffering a little stage fright and just about had it beat when he heard Jen say under her breath:"Oh my god!"
"What's wrong?" Matt stated as his piss started flowing. Matt looked up from aiming into the toilet and realized that he could see Jen's reflection in the window, and that maybe she could see the front of his body reflected in the window?
Jen was not looking at him however. She was looking in the mirror. "I--I um... just plucked too hard that's all."
Matt examined Jen in the window, and his cousin's face was turning beet red. Matt had finally stopped pissing. Matt was pretty certain she had stolen a look at his cock.
"I'm going to show the little slut!" Matt thought to himself. He had a sudden mean streak bloom in his mind. Maybe he was angry at the trick public blowjob the girls had done to him, but he had a sudden urge to be the one calling the shots.
Matt turned around with his dick still hanging out of his pants and approached the side of the sink. "What the fuck are you doing!?" Jen yelled at him in kind of a panicked beseeching tone--her eyes glued to his cock.
"I always wash my dick off after pissing. I don't want to be dripping and rubbing piss all over my underpants! Besides this makes us even, now you've seen me too." Matt hung his dick over the sink edge and turned on the water. Matt drew it out and made a big show of getting the temperature just right. Matt heard Jen sigh. He looked in the medicine cabinet mirror and Jen's eyes were glued to his cock, and she was rubbing her tits through the towel.
Matt's cock started thickening out and getting longer. He lathered his hands with soap and started rubbing his cock.
"Wow." Matt heard Jen whispered.
"You like it Jen?" Matt had a cocky smirk on his face as he looked straight into her eyes. Her eyes looked into his, darted to his hardon, and then looked back to his eyes.
Matt never would have had the guts to do this before his escapades with his three horny female classmates. But, Matt was beginning to understand the awesome power his dick had over horny women.
Matt was caressing his slippery soapy cock with both hands. "Yes," Jen said her voice cracking as she did.
"Big isn't it?" Matt inquired still with the cocky look on his face.
"Very," was all she said looking back and forth from Matt's cock to Matt's eyes.
"Time to rinse!" Matt said, and started rinsing off his swollen hard cock.
"Can-Can I touch it?"
Matt remembered all the times Jen had ran around in hot skimpy bathing suits at family beach get-togethers and teased him about being a pimply faced kid.
"I'm sorry Jen that wouldn't be right--we're cousins." Matt wanted to tease her the way he had been teased. He was beginning to enjoy himself.
"Please? I'll let you see my body again?"
"I'm sorry Jen," Matt said tucking his cock back away and buckling up. "I'm just not comfortably doing that."
"Sweet dreams Jen!" Matt added to himself:"you teasing bitch!" Matt looked back and she had a longing look and was biting her bottom lip--priceless!
Matt had a big hardon in his pants pushing at his belt. He walked out and his mom was there! She did a movie-style double-take at the bulge in his crotch. "What are you doing sweetie?"
Norene had a hard time not looking at the bulge in her son's pants. She started thinking that maybe Jen and Matt had placed something in his pants as a joke. But, she saw the nervousness and embarrassment on his face and discounted that notion.
"Nothing mom, I just had to wash my hands while Jen was plucking her eyebrows."
"Are you sure everything is okay?" Norene looked questioningly at her son. She was kind of worried about Matt and Jen in the bathroom together, then Matt walking out with a stiffy-and a big one at that.
"Yeah mom, everything is perfect. Was that what you said in the living room? That Jen was staying over?"
"Yes dear, that's exactly what I said. Didn't you hear me?"
"No mom, sorry. I wasn't trying to ignore you, I'm very tired. Can you make sure nobody wakes me up? I'm going straight to bed right now."
"Wow you must be tired to miss night-time TV! Usually you stay up until 11! Goodnight sweetie." Norene gave a last curious very brief glance at Matt's erection which had dwindled significantly. Had she been imagining things?
Norene went into her room. Matt had an inspiration and listened at the bathroom door.
Matt heard Jen muttering to herself:"Big fucking cock. Da-yamn bi-i-ig fu-uk-ing co-ock!" She was speaking in stutter-steps and Matt new she was masturbating. He broke into an evil grin.
He went into his bedroom and fell into the bed exhausted. Matt pulled the covers onto himself and fell into a deep restive sleep.
Matt had a very strange dream that a hovering head was sucking his dick. It felt very real. The detail was very graphic. The head's mouth would suck him deep and hard, then softly slip off the head over and over again. The technique kept changing. Matt started to rouse from his slumber, but realized that the mouth was still there.
"Wha-What's going on?" Matt whispered. He settled his hand down on the back of the head bobbing on his hard swollen cock. Jen's face came up for air.
"I'm sorry Matt; I just had to have a taste! You're not going to take my treat away are you?" She looked pleadingly into his eyes, hugging his spit-drenched dick to her cheek.
Matt realized Jen was wearing a big white tee shirt as a night dress. Jen had her other hand up under the shirt (and probably down her panties Matt was guessing). Matt glanced at the clock: 1am.
