Show me your tits, I’ll show you my cock

“What’s that?” the two girls asked simultaneously.

“Show me your tits and I’ll return the favour and show you my dick” Mark asked giving them a clear ultimatum.

The girls laughed and again whispered in each other’s ears before coming back with a response.

“Ok then” said Sarah, “we’ll show you our tits if you to jerk yourself off while we watch”

“You want to see me wank?” asked Mark surprised.

“Um yess! It would be hot. Have we got ourselves a deal Mark” asked Ali.

It surprised him to hear that they wanted to watch him masturbate but the chance to see tits was worth the deal.

“Uhh okay deal” he replied before unzipping his black jeans and dropping them to the ground. The girls watched on with anticipation as he slowly hooked his thumbs into the side of his underwear and dropping them to the ground. His boner sprung up as soon as the underwear dropped.

Mark noticed Ali staring hungrily at his cock while Sarah licked her lips.

The girls looked at each other and smiled before they both moved their hands to the straps of their dresses and slowly tugged it down, enough to reveal their bras.

Sarah had a black lacy bra that matched her black dress. The sight of her beautiful cleavage had Mark’s penis twitching. They were clearly massive.

Ali’s bra also matched own dress, an orange/red bra that looked lovely under her red dress. Her breasts were smaller than Sarah’s but still plenty of cleavage there which left Mark just as excited.

“Sure you can handle this Mark?” asked Sarah as the two girls unsnapped their bras and were holding the cups of bra by their hands.

“Yes! Oh god yes, please show me them” he said as he tugged on his own cock.

The girls smiled at each other again before dropping their hands, letting their respective bras fall to the ground.

The sight would be one that Mark would jerk off about time after time in his time at college.

He was staring at four naked breasts. Sarah’s bounced up and down at her every movement. They were massive, white and creamy boobs with generous sized pink nipples. Mark wanted nothing more to shove his face in between them and motorboat the fuck out of them.

Ali’s breasts, although not as large, still looked delicious. They were decently sized, sitting proudly on her chest pushing out towards him. Slight tan lines were visible, her nipples quite large on top of her aerola.

Mark started to drool looking at those nipples, he wanted to suck on them, they looked delicious.

It took him a couple minutes just to realise that he was already starting to complete his second task. He had been jerking himself for the last few minutes since the girls took their bras off.

They continued to smile up at him, squeezing their own breasts as he picked up the pace wanking his cock.

It wasn’t going to take him long to cum, not while Sarah continued to bounce her boobs around, squeezing them together with her hand and shaking them all around.

Ali also teased him, she started to squeeze her own nipples, delicately teasing them within her fingers as she stared him down with a sexy open mouthed face.

“I think I’m going to cum!” said Mark as he started to really puff.

“Good, finish it off babe” called out Ali

“Cum for us Mark, cum now!” Sarah said.

Mark picked up the pace once more, moaning, he knew he was about to explode. One last look at the two girls rubbing their own breasts was the final straw.

“Urghhhh... argh fuck me!” he called out as he started to unleash cum from his penis.

It was almost like a waterfall, squirts of cum flew up and then fell to the ground around him, over his feet and the carpet.

The girls giggled as they picked up their bras and began to re cloth themselves.

“Oh baby was that great, thanks for inviting him Ali!” said Sarah as she took away the view of her lovely breasts by clipping her bra back on and fixing up her dress.

Ali did the same and searched a draw for a set of wet wipes. She tossed them to Mark.

“I’d help you clean up myself but can’t afford showing up at the party tonight smelling like cum” she laughed as she picked up her drink and finished what was left of it.

Mark smiled as he cleaned himself up. What a night and he hadn’t even arrived at the party yet.
