Starfire and the dirty magazines
Sometimes a girl just wants to be a girl
"Star, maybe we should give Robin a chance to be on top for a while." Raven suggested sheepishly.
Starfire looked at her strangely for a moment, confused by the fact that Raven seemed so embarrassed about such a simple suggestion. Finally, as things began to become awkward from the silence, Starfire came to a realization.
"It's not Robin on top that concerns you friend is it, but rather you being on the bottom?" Starfire suggested, knowing enough about human emotions to know she was right despite Raven's attempt not to blush.
Starfire pushed Raven onto her back, catching her by surprise before closing in next to her and giving little kisses along her neck. Raven lay there, unsure what to do as Starfire began to giggle.
"Robin, our friend wishes us to play our parts! You are a boy and we are girls." Starfire said to encourage Robin to act.
Robin was still having a hard time wrapping his brain around his new discoveries and being thrown into a strange scenario he never thought was possible. The last time around Starfire had taken control, making it easier for Robin since he could simply react and respond where as now she was forcing him into control.
"Are you sure this is what you want?" Robin asked meekly, his knees feeling weak as he approached the bed.
Raven gave a simple nod in response, trying to hide how much she secretly wanted what Starfire had suggested. Unlike normally where as Raven could hide her emotions, being naked and untucked permitted her girlcock to simply spill the beans; Being thrown down onto her back with the sight of Robin approaching her made Raven's soft cock rapidly return to life.
"This looks like fun; perhaps when you have had your turn I might try laying back as well!" Starfire said cheerfully, making both Robin and Raven blush harder.
Raven watched as Robin slid closer and closer, finally grabbing her legs softly to help his aim. Her direct vision was clouded by her painfully erect cock, though when Robin finally pressed his cock up against Raven's tight hole she instinctively closed her.
"I'm… going… in" Robin said slowly and softly, not sure if he should warn Raven or just take her by surprise. As he pushed himself up against her she said nothing until the tip finally broke through.
"Ohhhh!" Raven cried out, biting her lip as she shut her eyes tighter.
"Does it hurt?" Robin asked, suspecting that he would know the answer first hand before the day was over.
"Yes, but keep going… just be gentle." Raven asked, accepting and even enjoying the discomfort as the closest proxy she would ever get to having her cherry popped.
"I'm sure you will enjoy it; all the girls in the magazines look excited!" Starfire said in an attempt to comfort Raven before placing a hand up on her friend's breast and tracing little circles as she continued to kiss and tickle Raven's neck.
It took several minutes for Robin to make his way all the way into Raven's snug bum and for Raven to adjust to the presence within her. Though he had no actual experience to compare it to Robin could already tell, that if vaginal sex was as amazing as what he was experiencing, why everyone seemed so obsessed with it. Despite having came only moments earlier his loins were already feeling overwhelmed. Robin actually appreciated the moments Raven was taking to adjust, giving him time to secretly try and cool down enough to not explode inside her. Though she didn't want to admit it, Raven was also using her pause not just to adjust to the sensation but also to cool her juices; she couldn't help but think how embarrassing it would be to cum before Robin did unaware that he was silently fearing the same thing.
When Raven finally signaled she was ready, both quickly realized that their sexual fires had not dimmed as much as they would have liked. Raven moaned as Robin pulled back, only a third of his length left within her ample rear and then gasped as he slowly pushed back in. Each time Robin's pace grew a bit faster. By the time he built up a reasonable rhythm he knew he was already almost over.
"Oh Azaroth!" Raven screamed as one of Robin's deep insertions pushed her over the edge, spouts of hot cum springing out of her twitching girlcock like a fountain before falling back to Earth to create a splatter pattern both her and Robin's chest and hips. Robin, caught so off guard by the beautifully erotic site, didn't even notice Raven tightening up around him until suddenly he felt his own geyser burst, shooting warm cum into her rear.
