It was a few weeks after Peter's eighteenth birthday and he began to feel strange. He wasn't sure that the radioactivity was affecting him but he was sure something was happening to him.
Peter was having mood swings, fevers, and he was also more easily aroused. From a girl bending over to just seeing an attractive girl, Peter became super horny and had to get rid of the growing pressure in his pants before he would ruin them.
While jerking off, Peter noticed that his erection would last longer, his cum was sticker and messier, and that he would become hornier after having an orgasm. Peter also noticed that the heat would also cause him to be aroused too. Peter, not knowing what was going on began to run some test to see what was going on but the results gave no answer.
During a week of intense heat and humidity, Peter could barely control himself and jerked gallons and gallons of his seed everyday. Each orgasm got more and more intense and he wanted more. To make matters even worse the central air and heat went out completely in the entire building.
On one boiling night Peter decided to sleep in his underwear and nothing else. As Peter slept his dream slowly and slowly became more erotic. Peter was in S.H.E.I.L.D.'s training room and he was soaking wet with sweat and was shirtless. He tried to leave the room but the only door was locked and there were no other exits.
All of a sudden Black Widow came out of know where and she was wearing nothing but a leather bikini. Upon seeing her Peter got strong hard on but averted his eyes to be polite.
"Oh my god, sorry Black Widow." Peter said trying not to look at her.
"No need to be sorry Peter, I need your help and only you can help me." Black Widow whispered into Peter's ears, causing goosebumps and making his cock even harder.
Black Widow then pulled Peter into a long and passionate kiss. They both explored each other's mouth and bodies. With a snap of Black Widow's fingers her bikini disappeared revealing her lush and perky tits along with her trimmed mound of pubic hair above her tight pussy slit. Black Widow then pushed Peter down onto a mat and slowly undid his shorts, she then licked her way down to Peter's hard member.
Peter couldn't believe what was happening and he did not want to end. Black Widow began to jerk Peter's monster cock which was covered in layers of precum. Peter moaned as her soft hand felt like heaven on his cock. Feeling than Peter was completely erect Black Widow started to lick the giant head of Peter's cock. Peter moaned as Black Widow sucked and licked on his head while her hands continued to jerk him. Peter didn't know how long he could last, but that was the least of his worries.
Peter felt how tight and moist Black Widow's throat was, and as she deep throated him, Peter exploded his seed deep into her throat, causing Black Widow to gag. She licked up Peter's cum remaining on his cock and began to kiss Peter. Peter could taste how sweet and salty he was on Black Widow's lips and he surprisingly liked it.
Black Widow jerked Peter's cock again and then mounted him. Her pussy was extremely wet and tight and it felt amazing to Peter. Inch by inch, Peter's monster cock stretched Black Widow's pussy. As they rode each other their moans and pants of pleasure filled the room and echoed all about. Peter thrusted into and out of Black Widow, and she came wildly and rode him like a bronco.
As Black Widow recovered from her orgasm, they switched position and Peter fucked her from behind. Black Widow's wet pussy caused Peter to fuck her with no mercy as he pulled her red hair back. Peter also stuck a few fingers into Black Widow's asshole causing her to scream in surprise and pain and with another hard thrust Black Widow came again falling onto the floor.
Black Widow then began to oil her massive tits and she told Peter to fuck her tits. The combination of the oil, precum, Black Widow's cum, and her soft tits drove Peter wild and while he fucked her tits, Peter played with Black Widow's nipples. With a loud grunt and encouragement from Black Widow Peter shot his thick, hot, and creamy load all over Black Widow's tits and her beautiful face. Peter then fell onto the floor next to Black Widow and they began to cuddle each other.
