First time sucking a cock

I realized that I was bi late in life. A buddy and I had met a older women(cougar) at a bar and after several cocktails(no pun intended) had gone back to her apartment. We stood with me in front and him behind her kissing and fondling her. I was kissing and licking her neck working down to her breasts while he was behind her massaging her tight ass and sliding a hand up the inside of her thigh. Her breasts were small but had those fantastic nipples that stood proudly as I kissed and licked and nibbled on them. I knelt down and slid her dress up her thighs and inhaled her musty scent. My tongue began working up her thighs towards her dripping honey pot. Unbeknown to me,my friend had freed his cock and was rubbing it between her ass cheeks. I pulled off her thong and started running my tongue in tiny circles around her clit. He, meanwhile attacked her pussy from behind driving deep into her sopping wet pussy. His cock slid out and right into my mouth. For the first time I tasted the delicious combination of her copious fluids and his precum combined as his cock slid into my mouth. The rest is history. I loved the flavor.
