Bearing with the nervousness of a second woman holding his dick in her hands, Natsu kissed her and then began moving downwards.
Since he was no longer a virgin, and had quite a lot of experience, Natsu knew that sex wasn't just ramming his huge dick inside the woman.
It was a long and sensual experience of first making the woman feel happy, and then finally enjoying himself.
Sliding downwards, Natsu kissed Rias everywhere his mouth passed by.
Pausing for a few moments near her breasts, since he had always been an admired of breasts, and the big ones particularly.
Natsu used his mouth to plate both her breasts and nipples, after which he continued going downwards.
Flicking her belly button with his tongue, Natsu's mouth finally reached the place he set out for.
Brushing his lips against the completely naked and bare pussy of Rias which didn't have a single stray pube on it, Natsu used his tongue to slide up and down against her labia.
"Mmmmm.... "
Enjoying the sweet and soft moans, Natsu continued what he doing, while his hands rested against the sides of Rias's pussy.
Pulling the thumb fingers of both his hands to the opposite sides, Natsu gently spread Rias's pussy open allowing his tongue to enter it.
"Aaahhhhhhh... "
With Natsu's tongue entering her pussy, Rias once again moaned as her hands gripped the bed unconsciously.
Not holding back at all, Natsu moved his tongue to swirl the insides of Rias's pussy which turned wetter by the second.
At first, Natsu thought that maybe it was his saliva which was leaking out, but seeing how sweet and intoxicating it tasted, he realized that they were the love juices Rias's pussy was making.
Moving his tongue with even more vigour, Natsu pressed his mouth completely against Rias's pussy and started greedily sucking on it.
"Aahhh darlingggggg!"
Resisting the desire to put his dick inside Rias already, Natsu continued pleasing her pussy with his tongue for a while, and then moved up a little.
Circling Rias's clit with his tongue, Natsu made it swell a little and turn puffier due to being teased.
As Rias continued moaning, Natsu used his teeth to gently take hold of her clitoris and repeatedly flicked his tongue up and down on it until her back finally arched up and Rias moaned louder than ever before.
"I'm.... Cummingggg!!!"
Using his mouth to drink up the bittersweet orgasm, Natsu used his arm to wipe away the juices left on his lips and chin.
Getting up, Natsu stroked the hair of Rias whose eyes were closed and enjoying her first even orgasm.
"Aaahhh... Haaaa... "
Opening her eyes while panting for breath, Rias saw that Natsu was looking at her with a meaningful smile which made her blush.
"You seem to be enjoying yourself."
Refusing to answer, Rias was about to look away when Natsu kissed her.
Not minding the fact that she would be tasting herself on Natsu's tongue, Rias opened her mouth wide and took his tongue inside her.
Moving Rias's legs to the side, Natsu positioned his dick in front of her slit.
Feeling Natsu's dick barely touch her pussy's opening, Rias stopped kissing Natsu and took in a deep breath.
"I'm.... I'm ready..!"
Nodding his head, Natsu resumed kissing her and gently caressed her body to ease the nervousness and anxiety Rias was feeling, before he finally started to move his waist.
"Ahhh.. "
As Natsu moaned from his dick entering Rias's tight pussy, Rias shut her eyes and clenched her fists tightly to bear with the pain of Natsu's huge dick entering her.
Moving at the same pace, Natsu's dick after a few second met with the first and last wall which stopped him from taking Rias's virginity.
Her hymen.
Kissing Rias and squeezing bother of her breasts to try and divert her attention, Natsu with a single thrust broke through her hymen and reached the deepest end of her pussy.
Moaning a little more from how much tighter Rias's pussy was now gripping his dick, Natsu didn't move and waited for Rias to get used to his dick.
It didn't take long for Rias whose eyes were filled with tears to resolutely nod her head and give Natsu the signal to continue.
Still, Natsu didn't directly move and massaged her soft and fluffy breasts for a while, before he started moving.
Pulling his dick back until it was almost out of Rias's pussy, Natsu gently made it go back inside.
"Aaaaaahhhhhh... "
Letting out moans which were filled with both plain and pleasure, it took Rias a while to finally stop feeling pain.
Once she did so, Natsu began slowly increasing the speed of pistoning until his original gentle thrusts had turned into quick fast paced thrusts which made Rias continuously moan.
"Yesssss..... Ahhhh, darling... "
Hearing how sweet and loving the word 'darling' sounded from Rias right now, Natsu unconsciously started moving even faster.
Gripping the sides of her waist, Natsu continuously thrust his dick which filled the room with wet sloshing sounds.
"I'm... I'm about to cum darling..!"
Thrusting even harder after hearing those words, Natsu was also about to cum.
"Uhmmm... Me too... "
"Then... Cum inside miiiiiii!"
Nodding her head, Rias barely managed to finish her words before her body arched from her second orgasm of the day.
Since she ready said so, once Natsu who felt Rias's orgasm turn her insides more wet, stopped hesitating and poured his semen deep inside her pussy.
