Brian

Liam had woken up with Louis and the disturbing realization that he hadn't had sex with him. Hadn't ever had sex. After checking that his penis was, in fact, attached, he'd kissed up Brian's feet, his ankles, his inner thighs, gotten a few scratches along side the ones Brian was giving him, grinned at the bitching coming from Brian before opening him up with his tongue and his fingers, then fucking him for a rather long time. He was kind of proud, being as it was his first time and all. They drowsed for a bit, then Liam went to go get them water.

When he came back it was to semen soaked sheets, Brian in the middle of them, and the realization that he'd never had sex with Brian. Never had sex at all. So it was with a great deal of possessive jealousy that he fucked Brian this time, hard and biting his throat, his skin, his shoulders, trying to erase the marks the other man had put on him. He wrapped around Brian claimingly when he was done, growling softly until he was ready to let Brian go. He went to get a wash cloth from the bathroom.

When he came back it was to a bruised and sweaty Brian, lying stretched out in the sheets. Liam growled, realizing he'd never had sex with Brian, never touched him. He crawled onto the bed and pinned Brian, glaring at him, "Who was it?" He bit over the mark on Brian's shoulder, sucking it hard, pulling blood to the surface. "You're mine."
