To Kill For Love

Chapter Ten

Waking up to a tongue in his ass was never something Katsuki expected to experience. Once it happened though, he could not say he hated it. A moan escaped him, and he writhed. Scarlet eyes peeked open to find a head of red and white hair between his legs, his hard cock resting on top. A skilled tongue rearranged his insides. Fuck, he could feel his orgasm building already.

"Shouto-"

Fingers dove into his mouth, cutting him off and coaching another moan from him. He looked up at Izuku, who sat on his knees, naked and very hard. His heels dug into Shouto's toned, muscular back.

"Morning, baby." Izuku crooned softly. "Did you sleep well?"

A nod.

"That's good. Shouchan and I had an idea for you."

His eyebrows raised curiously.

Those lips curled into a sexy smirk. "We want to mark you, but we know a permanent fix isn't desired just yet, so we wanted to know if you would like a temporary one." Those fingers left his mouth. They trailed their way down Katsuki's body, leaving a wet mark in their wake, until they reached the uppermost part of his inner thigh.

All humans had multiple sets of scent glands, but most of them hardly excreted much in terms of scent. The ones in the junction of the neck, of course, were the most known. They secreted the stronger scents, and only they could be used for permanent marking, to properly intertwine one's scent with another's. Next came the smaller ones in the wrists, most commonly used for scenting. They picked up scents easily, so people would rub them against another's neck glands to mix scents for a couple of hours. These could not retain any kind of marks. The final glands, and most unknown, rested in the inner thigh, closest to the pubic bone. Being dangerously close to genitalia, hardly anyone ever used it. These glands produced the most sex pheromones. In the past, historians assumed the pheromones came from the respective glands but were ultimately incorrect. The glands resided deep inside the inner thigh, so it took a strong bite to mark them. Once marked, the effect would last a month or two. It acted just like a regular mating bond, but temporary.

Shouto pulled back and looked up, his mismatched eyes meeting Katsuki's. "Only if you're comfortable."

"I can't... I won't be able to mark you back." Katsuki admitted. He looked between them, expecting some form of disappointment, but all he found was understanding.

Marking an omega's thigh was easier than an alpha. Not only did alphas have a stronger bite force, but they did not have to worry about missing the slim window of time because they had to dislodge from a knot.

Izuku's spare hand tenderly pet through blonde locks. "You will." He stated confidently. "Our situation is very different, and we can get you the window you need."

His brows furrowed. "How?"

Shouto moved forward, his lips immediately locking with Katsuki's. The omega hummed the moment he tasted himself on the alpha's lips. Soon to be his alpha. Well, one of his alphas. "The gland is most accessible right at the peak of an orgasm." He whispered against Katsuki's lips. "Getting you off is easy since you're made to release back here too."

A hand wandered dangerously close to his soaked hole, and he moaned.

"Shouto and I discussed it while you slept." Izuku stepped in. "What you need is an obstacle-free window between the orgasm and the biting. Unfortunately, commands and orders won't work for this."

"But lucky for you," Shouto crooned with a small smile. "We've been fucking each other for years."

Scarlet eyes widened. "You're going to fuck each other so I can mark you?" He whispered, almost disbelieving their words.
