So waht effect does this new mark have on him?
Things to be seen
Alex doesn't feel any differently. Emily doesn't make an stunned sounds to indicate a physical change so he guessed he already looked like her perfect little sis. The thought sent shivers of pleasure through his whole body. He was already her perfect little sis, just thinking that gave him a jolt of pleasure. He couldn't feel his mind changing as it had when he wrote 'ADVENTUROUS' on himself. That didn't mean none happened, he might just have to wait for the show themselves.
He was pulled from his thoughts by the feel of Emily pulling him up. He went with it and found himself on the couch next to her. He looked down to see the marker still in her hand. She waved it by his skin and he wondered if she wanted to write anymore on him. He felt a submissive pleasure at the idea of Emily molding him into her perfect little sis.
He felt like he was repeating himself in his mind. But if this is what Emily wanted of her little sis that's all that mattered. The marker in her hand moved away. She put it down as her eyes wondered his body. "Hmmm, you'll be my little sis?"
"Yes whatever you want big sis." The words came out of his mouth without asking for his brains input, it was just the answer to her question.
"You'll do what ever your big sis tells you." Her hand moved down his body and traced the letting on his pubis.
"Whatever you say." Alex lets out as her fingers move closer to his cocklet.
"You'll fuck whoever I tell you to fuck?" Her forefinger and thumb pinched his soft cocklet and began to slowly stroke him.
"Y-yes! I'll be you little sister slut, I'll bend over and wiggle my sluttly ass and get plowed by whoever you want. I'll get on my knees and service everyone you tell me to." The words flowed out easily, the were just the natural response to his big sisters question.
"But you'll only be mine." This one was little more than a whisper, he could hear a hint of worry in her voice and his very being cried out to answer.
His brain tried to answer at them same time as his mouth. He just made a girly gasp as her fingers kept working his soft self. He tried again but couldn't, so he just kissed her. He felt her relax into him, her free hand wrapping around his body as her fingers kept up their steady pace.
"I love you big sis. OH!" Alex said as the kiss broke. Her fingers squeezed lightly when he said that and he felt himself get all fuzzy as he she the happiess in her eyes.
"I want you fuck you." Emily growled as she swung leg over his hips. Straddling his hips. As soon as she said it he felt his cocklet twitch in her fingers.
It was a strange sensation, two marks on his body trying to do two different things to the same body part. He couldn't disappoint his big sis so he rubbed away 'SOFT'. The second it was only slightly marred his cocklet sprang to life. Her fingers suddenly could only pinch the tip. She moaned in approval feeling his cocklet rise. Her hand wrapped around and jerked him, making sure he was fully hard for his big sister.
"Oh god little sis, you cocklet so just so fucking cute." She lowered herself and grinded herself against his length. She felt so warm and wet as she rubbed herself along his short length. He let out a feminine moan at the pleasure he was feeling. "Little sis do you want to fuck me."
"GOD YES BIG SIS! PLEASE LET YOUR LITTLE SIS PUT MY CUTE LITTLE COCKLET INSIDE." Alex let out as he felt her dripping wet entrance push against his crown.
"I love you little sis. I love you so much." Emily lowered herself onto Alex's cocklet and her let out his a series of pleasured noises as she sank the whole length into herself. It wasn't very long but he knew this is what she wanted. Letting her mark him really did wonders for his self worth, ironically.
"I love you too big sis." As he said that she leaned down and locked lips with him. She started to ride him slowly, lifting her body up on her legs she just let gravity pull her back down. It wasn't even close to the mindless pleasing he did while eating her out, or when she fucked his face or butt with the dildo. This was the sharing of love between two people, one devoting themselves the other claiming ownership.
Emily began to speed up her ridding slowly, the rhythm she set echoed in kiss. As her tongue pushed its way in his mouth and he pushed back, even in his he was submitting to her. Whatever she derived greatest pleasure from he got the pleasure of serving.
His hands fianly moved from her hips around to her butt. He felt a shameful pride at knowing his butt was better than his sisters. She moaned into his mouth as he felt her up. His fingers dancing all over her soft skin feeling the firmness beneath.
"Mmmmm." Emily moaned into his mouth and then pulled back. "Tell me what it was like when I fucked your ass."
"It was soooo good." Alex moaned out. "Feeling you pushing your cock into my slutty butt. Not being able so see as you fucked me. Mmmmm." At the memories Alex's butt felt empty but he kept talking. "I feeling you press me down, not being able to move as you use that dildo so milk my cum out. Feeling myself cum just from your fucking, letting me cum like a girl for the first time." Alex started to move his ass on the couch to try and get some stimulation.
"Oh fuck Alex." Emily moaned and bit his neck. She sank all they way down and he felt her begin to orgasm. Her tightness increasing around his cocklet. But it wasn't enough to make him cum, he felt like something was missing, like he just couldn't cum.
"Can i please cum with my cocklet big sis." The words flowed out naturally. As they did he knew one of things his new mark did. He could cum with his cocklet if she let him. He didn't think it would be the same with his butt, she loved watching and knowing he came like a good femboy sister too much to limit it.
"Yes little sister you can cum. Cum in your big sisters pussy." The words led to another mini orgasm from Emily. The extra stimulation making his cocklet empty all it could into his big sis's pussy. It wasn't much, only a few spurts, barely enough to leak out when he pulled out but know he obeyed was more pleasurable anyway.
Emily stayed on top of him for a while. Neither talked, enjoying the closeness and warmth of each other. When Emily stirred his ear perked up, waiting to serve.
Emily lifted up pulling Alex out but not getting off him. "Clean me up little sis." Alex sunk down and dove into her pussy without question or hesitation.
She dripping from the sex and there was a hint of sweat in her skin. Alex did all her knew to make her moan. When he got his first taste of his cum his arms wrapped around her thighs and pulled her down. Making sure that none of it went anywhere but his tongue.
He managed to get Emily to cum one more time before she lifted herself up. "Good girl. Now time for a reward." She moved away leaving Alex half on half off the couch. "Get on the arm and bend over." Alex did so. His feet touching the floor, his stomach pressed against the arm, his head resting on the cushion.
He didn't move, just waited for Emily to do whatever she wanted. He could hear the distinct sound of a paper bag being opened and his but began to wiggle excitedly.
What does Emily have in store for her little sis?
