That is not the kind of man you want to lose your virginity with,” Lily said.Sarah burst into laughter at Lily's comment.“It's not funny,” Ava scowled.“Actually it is. Better warm up to the idea because when Alpha Lucas Raventhorn wants to take you, he will in the roughest way possible.” Sarah advised.“You mean like last night? I thought he was going to rip you in half.” Ava rolled her eyes.“I like my men rough.”“Well, I don't.” Ava retorted.“If you are looking for flowers, love, and vanilla sex. You are a concubine to the wrong alpha.”“Ain't that the truth.” Ava murmured under her breath
