By confirming their love

Mash Kyrielight will be honest with Ritsuka Fujimaru when he asks if she loves him. If Ritsuka unloads into mash or any girl, he can choose if it will impregnate her.

"Mash, I wanted to ask a question. Do you love me?"

"Y-Yes!" Mash chirped, blushing up a storm. "I've been in love with you since you saved me when the bomb went off before the first mission!"

"Then, would you like to have..." God, this was so much easier to write out than to say. "...Have sex?"

"Y-Yes! I-I mean... i-if you really want..." Mash said blushing, bouncing over to the bed. Ritsuka followed her over, disrobing as Mash removed her pants excitedly. The Master took the Sex Note and put it on the nightstand before laying down on the bed, Mash bouncing next to him. The Shielder blushed as she bounced onto the bed, carefully adjusting her sex to insert the dick. she closed her eyes as she grabbed onto the erect shaft, lowering herself onto it.

"Wh-what next?" That adorable look, his shaft already going harder. Damnit Mash, why are you always so adorable and sexy!? "U-um, bounce up and down on it? I-I'll try thrusting!"

Ritsuka grabbed Mash's thighs as she bounced on top of him. He knew she'd be satisfied regardless, but he did want to put in the effort regardless. "Mash, I-I'm cumming.!" He said, releasing into her. The two of them had gone limp, the mix of cum and blood from mash's broken hymen as the two panted.

"That... was... amazing, senpai..." Mash panted out, Ritsuka nodding in response. Now, the time to think was upon him.
