STB: Chapter 31 **

"Are you still not awake, Sayaka?" Alex asked as he started to remove her bra, freeing her breasts from their confines. He then slowly removed Sayaka's thong, noticing liquid stretching out from her thong to her slit.

Sayaka's breathing becomes ragged as she grits her teeth and clenched her fist,

then Alex also removed all his clothes as he slowly spread her legs revealing her glistening folds, Alex then rubbed the head of his dick to her slits, seeing no reaction, Alex continued until Sayaka let out a soft moan, which she immediately covered her mouth, looking to the side.

Sayaka gasped softly as Alex teased her, her body trembling with need. 

Sayaka arches her back, pushing her hips up towards his, trying to take more of Alex's cock.

Sayaka's pussy is too wet with her arousal, and she knows she won't last much longer without being penetrated.

"... Alex..." Sayaka bit her lips.

"Oh? What's this? turns out you're awake after all" Alex grinned.

"Please..." She mumbles.

"Hmm? Please what?" Alex feigns ignorance.

"Inside... me..." She mumbles while clenching the sheets.

"Inside you?" Alex said with a grin as he enjoyed bullying Sayaka, especially in bed.

"Put inside... Me, please... Cock... I need it..." Sayaka begs, her voice filled with desperation. She's never felt this way before, and she can't deny the intense pleasure she derives from Alex's touch. 

She looks at Alex, her eyes filled with need and desire, ready for whatever he has in store for her.

"Since you love being filled up that much then I guess I have no choice" Alex said with a grin as he slowly pushed his hips into hers.

Sayaka's body tenses as she feels Alex's cock pressing against her entrance. 

She takes a deep breath, steeling herself for the sensation of being filled again. With a slow, steady speed, Alex pushed his dick deeper, stretching her walls until he was fully inside her. 

"Ooh!~" Sayaka moaned loudly as she felt the tip of Alex's dick reach the entrance of her womb.

Sayaka's body adjusts to the feeling of being filled. She arches her back, pushing her chest out, offering Alex more of her large breasts Alex saw this and buried his face in her large breast as he suckled her nipples.

Her hands grip the sheets beneath her, her nails digging into the fabric as she starts to lose control.

Alex continues to thrust his hips against hers at a moderate speed as the sound of Alex's dick going inside and out of Sayaka's pussy echoes throughout the room.

*Slsh!* *Slsh!* *Sloosh!*

"Ohh! Alex! So deep!~" Sayaka moaned sensually as she kept her hand on her mouth to muffle the moans she was releasing.

Alex continues to pummel her womb with moderate speed while his dick molded her insides with its shape.

She moans when her hips meet his in a rhythm that sends waves of pleasure through her entire body. she knows she won't last much longer.

"A-Alex! I'm close!" Sayaka yelled but Alex slowed down his thrust.

"Hold it in wait for me" Alex said, causing Sayaka's eyes to widen in surprise at his command, but she didn't question it. 

Instead, she focuses on the intense pleasure coursing through her body. She digs her heels into the mattress, pushing herself further onto his cock as Alex continues to thrust into her.

"Alex! I can't hold it anymore!" Sayaka yelled as she wrapped her arms around his neck.

She whimpers, her orgasm building rapidly. She clenches around Alex, her walls squeezing his cock tightly as she nears her climax.

"I'm close Sayaka just a bit more!" Alex said as he sped up his thrusting.

Feeling Alex's thrusts becoming more urgent, Sayaka knows he is close to his end as well. With a determined effort, she holds back her orgasm, her muscles clenching around him tightly. She pants heavily, her chest heaving as she tries to regain her composure.

"Cumming!" Both of them said together as Alex filled her womb with buckets of semen while Sayaka squirted all over Alex's shaft.

×××××

"Oohh!~ Alex! I can't! Ngh!~ I can't hold it!"

"Just a little bit more!"

She moans, her hips bucking against Alex in search of release. Despite her best efforts, she can feel her climax building again, threatening to overcome her at any moment.

Feeling Alex's cock pulsing inside her, Sayaka cries out as she finally releases her held-back orgasm. Her body convulses around Alex's, her walls clenched tightly as waves of pleasure wash over her. She moans loudly, her hips moving erratically as she experiences her second orgasm of the night.

"W-Wait Alex I'm still sensitive!" Sayaka complained but Alex was not having any of it as he continued to thrust his hips into hers.

"Nhgh! D-Damn it Hmgh!~ Alex! My brain! Hya!~ it's turning into mush!"

"Damn you! Nhgh!~ Just cream pie me up already!"

Sayaka's voice is a mixture of pleasure and desperation, wanting Alex to fill her up completely. 

As Alex continues to thrust, she can feel his hot seed filling her, and it only adds to the intensity of her orgasm. She collapses beneath you, panting heavily.

"Mmph!~ Alex!~"

Sayaka passed out with Alex's dick still buried deep inside her pussy who kept spraying semen inside of her as if trying to get her pregnant.

Seeing this, Alex frowned as he realized he forgot to ask Sayaka why she fled when he was drinking Yukina's blood. He glanced at the door, where there was a crack, causing him to grin and hope she enjoyed the show.

Alex slowly removed his dick buried inside her, causing Sayaka to moan softly as if she doesn't want it removed.

Alex's seed began to ooze down from her gaping pussy like a waterfall.

Alex noticed that the peeping tom was already gone, he then covered both of them with the blanket as he hugged Sayaka's waist while placing his other hand on her boobs.

×××××

The next morning Alex felt Sayaka shift around his arms and was about to wake up.

"Hmm" Saya groaned as her eyes fluttered and noticed Alex's hand wrapped around her as she snuggled to him even more, Alex notices causing him to ran his hands from her waist down to her crotch where he pinched her inner thigh causing her to yelp.

"Alex! Don't do that! I'm still tired from last night..." Sayaka looked at him with a pout.

This causes Alex to raise his eyebrows.

"Then tell me why you fled from the lab last night?" Alex asked, causing her to pout even more and try to get out of his arms.

"Let me go, you idiot! You insensitive perverted 4th progenitor! Hmph!" Sayaka said but she stiffened when she felt a pinch on her neck causing her to let out a moan.

"I-If you think this will make me forgive you!" Sayaka said while gritting her teeth as Alex removed his fangs from her neck and licked the excess blood causing a shiver to run down her spine.

"Ahn~ T-Then you're absolutely right you perverted progenitor..." She said as she turned around, wrapped her arms around his neck and kissed him.

Sayaka broke the kiss first and gave Alex a hug pressing her breast on Alex.

"Do I have to reveal it..." Sayaka pouted as she felt Alex caress her back causing her to melt.

"Well I do want to know and I'm curious" Alex pinched her butt cheeks causing her to release a soft moan.

"... Fine, you win... I know you always get what you want... But promise me you won't get weirded out..." She said, causing Alex to raise his eyebrows.

"Sure?" Alex said nonchalantly.

"Alex! Be serious!" Sayaka said as she broke the hug and looked into Alex's eyes.

"Okay, I promise" Alex said as she squirmed in her place.

"Well?" Alex said, causing Sayaka to glare at him but shrugs.

"... I feel turned on when you sucked Yukina's blood..." She confessed, causing Alex to freeze for a moment but returned immediately.

"A voyeur huh? That's fine"

"Fine? That's all? You won't get weirded out or angry?"

"I'm fine with it as long as you don't step out the line like having sex, kissing is also fine but only allowed in bed when I'm having sex with one of you" Alex said in a rare serious tone causing Sayaka to gulp and nod repeatedly like chicken pecking rice.

"Good" Alex said, returning to his nonchalant mood.

"... Also what do you mean 'having sex with one of you'? Do you have other girls besides me?" Sayaka asked not to mind having another sister since she realized she couldn't beat Alex alone in bed.

Sayaka also knows that she has a special place in Alex's heart as the one who took his first time along with being his first blood servant so she's not worried she'll be replaced anytime soon.

"Nope, I have no one, let's just say preparation for the future? Anyway let's get dressed, breakfast is already prepared" Alex said changing the subject causing Sayaka to narrow her eyes but nod in the end.
