Yes

Andrew thought about stopping Brian from exposing and mauling his chest but felt he might as well give him something more than last time seeing as he would be braking up with Brian shortly, even if he were revulsed by the thought of his best friend ravaging his body the way Andrew did to his previous girlfriends.

Brian began caressing Andrew’s breasts, then playing with his nipples using an index finger and thumb, lightly squeezing, tugging and rolling them.

Andrew’s nipples were particularly sensitive, especially when erect and exposed to the cold, and Brian’s ministrations sent weird shivers and vibes throughout his body.

Such succour naturally triggered Andrew’s biological reflexes, and he found himself becoming erect from the erotic attention of his best friend, so much so that he felt the sanitary pad giving way below his thong.
